THE BLACK BOX
The Black Box, Jacobs Power Packs and the "Fake Batteries" have been
around in various incantations and upgrades for the past fourteen years and
some of my original packs date back to the sixties with different
"chemistries", battery slang for types of batteries. There are several
thousand
of these packs out there.
The pack came about
because I had another popular brand drop
dead in the middle of a Wedding. After that, I built my own. I put my
plans on the web. For every one built, five asked me to build one for them. I said when I retired I
would.
With that said: I have no secrets. I am a
one man company, I believe in simple, affordable, reliable, portable
products. I am semi retired, it keeps me busy, prevents boredom, and
I have enough contacts in the electronics fields that allow me to purchase
quantity and quality. We have no corporate meetings, no stocks, no
options, no employees, no headaches. Just me now since my partner and
beloved wife passed on August 30th, 2007. Since I have the
longest warrantee in the business and the best price it behooves me to put
quality stuff in. I hate comebacks.
Sometimes I get behind, "buried" as my wife used to say. I'm putting in more hours
than before retirement.
I build limited numbers, all by my hand and a little help from a CNC machine. I
have no
advertising, all is word of mouth and people like what I make so they tell
their friends. So much for advertising budgets. I'd rather put it in
service. Service is when you need me.
We have no distributors, no large chains of retail
stores. No sales teams, rallies, parties, or win a trip for sales
excellence. Basically you are dealing direct, no markups, and from a
fellow photographer who kind of learned from shooting what works and
what's really ridiculous.
In addition I can be reached by phone most
of the time. I prefer the weekdays allowing some time on the weekends
to spend with life doing what photographers like to do....
Covering politics... it's exciting work! Sort of like the running of
the bulls in the
nine-day festival of
San Fermín in
Pamplona. The
Politicians are running a lot of BULL and the paparazzi trample each other
to get a shot. Same result. BULL whether it's verbal or 1400 pounds of
tortured animal both cause harm.
Career wise I shot over 400 weddings working out of a
Wedding Mill with bookers, shooters, album sellers, and a boss who studied
under the Third Reich. I then went on my own. I starved like
many to get started and did it part time to keep food on the table.
"I have been around the block", as they say and
"I'm one of the few who hit those numbers without being
institutionalized". It was good training as I understand the game and
have enough ideas from the past and all the communication I do today to be
of help to those starting out.
Today I prefer covering news, PJ, and
shooting product, basically picking and choosing. Weddings are a different business
today and very competitive. These legs are too tired at almost 65 to run anymore,
while warding off the evil doers. I'm writing a book on the Wedding
industry and Wedding Photography. Parts of it, about a quarter of the
pages is available on this site. As I bring the other sections to
fruition, they will be added. Some have told me it's very funny...
the horrible truth is most of it is very real and hopefully very funny.
Hope these few points answers your
questions...if not I am available. I will call you if you do have
questions. Just send me an email with your number. Real voice, real
people talking on a phone. I hate typing long responses, a little
arthritis does that to you.
THE AA CELL DESTROYER
I hate AA cells, small chargers, and changing AA batteries.
I don't hide it, please respect me for my opinion and I'll respect yours. If
you are a devotee of AA cells, and think the MAHA 204 or the Ray-O-Death
or Neveready
Charger and AA cells are Ok for a Wedding, this place isn't for you.
To me a guy lugging twenty AA batteries going for a shoot makes no
sense. If you do use AA cells in NiMH , here are some good tips.
-
Don't mix chemistries, types, brands, lots or capacity of the cells.
When you put cells together, you have basically built a pack. It may store
in the camera or flash or it may be in a holder but you made a pack
generally with very POOR connections.
-
Cells should be marked and kept in specific sets and kept them together
for performance to stabilize.
-
NIMH cells do not get better with age, it's the reverse, they actually taper off.
Since
NiMH tapers and deteriorates as it gets older, the point you have to
change batteries increases or changes.
-
You are kidding yourself if you believe the life expectancy of the NIMH
is as promised. We are smart enough to know not to buy the "Brooklyn
Bridge". But, just last week three idiots bought the water rights under the
bridge. Paid Cash too!
NiMH do not recharge as many times as professional NiCads.
They also have a shelf life no one talks about. NiCads are actually better
in the C and D cell commercial categories. That's why they are preferred
in the higher power packs, the Ni-Cads and Sealed Lead Acid batteries are
the preferred power source for longer use and less depreciation in
professional units.
So why the popularity of NiMH? Simple. it's the cheapest battery to make,
(CHEAP, HIGH PROFIT) least offensive to the environment, lightweight and it works in all the
toys like phones, beepers, Walkmans, Boison-berries, and Vibrators.
And we all like our toys!
-
Li-ion and Li-ion Polymers are popular now
but have problems. Severe threatening problems. Just ask SONY, DELL,
APPLE. IBM, Toshiba, Panasonic and a few others in the laptop business.
Common denominator SONY batteries and Toshiba batteries under license.
from China, just like Pet Food, kids toys, car tires, etc.
Also note several fires with Li-ion involving those used in model
airplanes (yes, they are used in model airplanes) and cell phones.
Also when they blow in cell phones, they can kill you as happened in Korea
recently. They cannot come in contact with air. Never open the case. the cost so far
is over 470 million dollars. The main source for Li-ion batteries is
China. (As if you didn't know!)
-
This is reality in
the battery business. If you are not in the battery business, like anything else in life,
like buying a car, it's not what they tell you more often it's what they
DON'T tell you. I will tell you.
-
FAST and Faster: Definitely stay away from chargers that
promise faster, faster, faster. Being fast or "being one with speed"
is OK in NASCAR, the Olympics, serving tables, drag racing and working in
a brothel.
I DON'T GEAR FOR THE FAINT AT HEART
I gear more toward PJ, Event, Model and Wedding shooters who need lots of shots
and more convenient flash usage then with AA cells. My units average
over 1000 shots. A lot depends on the flash, and that’s more than I or any
other shooter will use in any wedding. If you are one of
those who shoots more, get the 2nd Black Box back up pack for 119.00 dollars more or at
least a Tuxedo for 79.00. That's
1600-2000 shots on hand with a two second swap.
The Black Box is just that, a stealthy black box filled
with more power than the average shooter can shoot in a long session. And
it only comes in black, black and black.
-
No difficult color
decisions here. It comes in Black, Black, or Black.
-
No battery or financially draining complex electronics or
extras.
-
We use one really big reliable quality brand heavy duty battery.
-
While the other guy is carefully scrutinizing his fuel gauge waiting for
all the lights to work and scared to death they won't come on, you are
capturing images.
-
Speed kills.
I do not gear toward those who are impressed with speed.
The measurements, thus actual counts are misleading. On a FULL dump,
you can do this, set your flash to manual and aim it at a foreign country, that's a full
dump. We average three seconds or less, and 800-1000 shots. In auto mode
and closer distances, like wedding shooters who do forty-five shots of the Brides
shoes, twenty-two ring shots and at least fifty-six at the thigh high
garter grab you will use less juice, as less power is is drained
from the capacitors squelch circuit at these close distances.
-
My pack will keep up with the others. Full
pops slow any strobe down. The accelerated pack will recycle faster but
will give you far less shots.
-
A flash can only operate at max for a while before there is trade off. You
trade your money for a new one. With the rash of burnt
units out there from too frequent a shooting and finally the unit
overheats, you pay for the speed twice.
NATURAL SELECTION of POWER
|
Currently, there are three methods by which you power a strobe:
|
AA Alkaline Batteries
The OLD Reliable Backup
Slow and Inefficient
Good for Turtle races. |
Rechargeable" cells in NiMH
Cheap, unpredictable, charge by heating the mash, shorter life, also
prone to a single cell stopping a pack. |
External Power Pack
Choices! Go to very expensive power packs made by outside
vendors not licensed by either Nikon or Canon |
If
you are an ALKY read no
more and go home |
There is an AC Adapter port a
manufacturer provides for his brand of flash made to his specs by both
Nikon and Canon. They use 8 or 12 AA cells in their packs so you
can now carry forty NiMH batteries and any one that fails depletes the
capacity of the pack. |
Utilize the battery compartment with auxiliary
power of the same or better low voltage quality but more quantity.
I'm the last guy. I just increase the power supply and do not play
with the dynamics of the strobe. Read on below... |
SPEED KILLS, AC PORTS and LOSSES
The biggest question we get is how fast.
Speed is pushed by many
battery manufacturers because they feel it's the selling edge. "More speed is better". In reality speed has a price. You are pushing
limitations whether behind the wheel or with over-clocking a computer
which is altering the
current to the CPU. Usually a reduction in life cycles, higher costs, maintenance and
battery life. Plus you are using a port on the strobe not designed
for what it is about to receive.
-
We do not use the AC port on the strobe.
The Quantum Turbo, Lumedyne Cyclers, Digital Camera Battery and the Jack
Rabbit all are good units, basically offering speed and better capacity
than AA cells. They cost more because of the electronics. The more
the electronics the more the failures the more the warrantee work, the
more the losses. So you charge more to pay for more.
-
Speed is attained by accelerating the 8 volt
to 12 volt battery clusters in their pack and using a fly back transformer
or use another capacitor larger than yours externally. They then reroute and use the AC port
direct to the capacitor.
-
This results in faster shooting and two
anomalies. In Canon usually a toasted strobe, those nasty trace burn
really become apparent to the repair guy, and in Nikon the yellowing
of the flashtube and in some cases melting the plastic. the small but
powerful strobes such as the SB-800 and the Canon 580EX and EXII are
basically pushing the electronics to the hilt and the accelerated packs
push them over the cliff.
-
But the strobe still needs to be powered for the LCD screen
or power to the camera for messaging. These units still require the
use of four AA cells to make the unit work, so now you have two battery
sources to consider. A pack and AA cells.
-
With accelerated packs you have bypassed
some of the mechanisms. I truly believe based on size measurements and a
little research both Nikon and Canon have pushed their best selling units
to the end of the power curve. "Sort of tweaked to the nines".
The max amount of power attainable from four AA cells in a standard flash.
I am very reluctant as stated to try to push it further with acceleration.
Warrantee wise the way Nikon and Canon look at it, anything
else plugged into this external port voids their responsibility if you
make a volcano out of your strobe. The use
of anything other than their specific brand especially through the AC input on the
Nikon SB-800, the Canon 550-580 series and the METZ 54 series is easily
detected on a repair bench. Just look for burn "traces" at the in port.
The manufacturers own brand won't effect their strobes, the voltage is too
low.
-
Everybody who makes battery
packs would love to use this port, me included, it's neater, but remember
I said it comes at a price. Again that's a direct AC input. If it
does blow or spark they know where to look. That's why the warning about
any product other than theirs. So if you happen to torch your strobe by an
accelerated speed product, with an accelerated trigger finger, overheat
the strobe... this happens every day, the manufacturers can tell in a
heartbeat what zonked the strobe. You can't hide burn traces in a
specific location. As one person stated; "the fastest strobes can
recycle in 0.8 and other promises 1.3 seconds". That's fast, very fast.
BUT. If they blow, that speed is reduced to slow, very slow, like
eternity...
ADDED VALUE
We do not use cardboard covered vinyl in our cases because they absorb moisture. Nor do we use cheap findings like metal belt clips and miniscule shoulder
strap assemblies. Nor stitches that come loose, nor painted on logos, nor
barrel connectors. We stuffed it into a box, a BLACK
BOX, and after many meetings with the marketing people and a few beers we
called it "The BLACK BOX".
Two minutes later I threw the marketing guys out. They thought I was paying for the beer. We did add racing stripes in either red or gray to the left side. That
was in response to the critics at the PMA who thought it was too plain, too retro, too simple.
When we explained the power reserve, the redundancy, high tech charger, and low-cost they thought I was
under pricing the other guys.
No days off. My packs stay on the charger indefinitely. My chargers are
intelligent and do the thinking for me and make my batteries last. Up to
seven years. And are always at the same temperature, same 100% and peaked
ready to go to work in a moment as long as you follow instructions.
BLINKING LIGHTS ARE FOR
THE HOLIDAYS
Two things make no sense to me. Man's fascination
with blinking lights and now lower powered blinking LEDS. They add
sophistication, cost justification and interest to a normally dull and dry
product. You are buying a storage device not the controls to a nuclear
power plant. Just another distraction.
I don't use BLINKING lights to indicate when the unit is running low.
Why, because they don't really work, that's why. In a nutshell, they draw power,
they require a lot of electronics that can fail, they raise the price, take up room,
have to be calibrated to the battery
and retain heat in the battery pack causing corrosion
Do you remember when cars in the late sixties to seventies had nice
gauges on them replaced with
IDIOT LIGHTS. It was a lot CHEAPER to manufacture and install idiot
lights than gauges and most folks couldn't interpret the gauges anyway.
The idiot light came on after the car dropped dead. Same with the flash
units. Just before it drops dead. So you really need two units not one.
Nice subliminal sales approach.
In most cases idiot lights on Sealed Lead Acid batteries and others are
not even a true idiot light. They are LEDS reading from comparators. The
Sealed Lead Acid battery has a flat power curve , basically they remain
the same till exhausted. They run straight and then they nose dive.
To you this means more consistent time between flashes. The comparators
"compare VOLTAGE" guessing how much is left. So if the voltage stays the
same for 3/4 of the life of the battery what is the use of having an
inaccurate gauge. Thus we
power the
flash tube through the battery door with fake batteries using simple
Quantum "M" cables. They almost got the cables right. Read
on.
QUANTUM T2, T4, T5
FLASHES
Sorry, you have to buy
Quantum or Lumedyne or Digital Camera Battery. We do not build Turbo or Super Speed direct 325 volt
connections.
WE DO NOT USE the little port that is built into
the flash for the AC pack or direct connections.
The risk of replacing
equipment it just isn't worth it to me.
FOR SOME A BETTER IDEA
We use SEALED
LEAD ACID batteries and a much improved, actually a full one amp variable
rate charger with safety controls built in. It lasts longer, no
maintenance, no calibration, sit at 100% indefinitely.
It's less expensive per amp hour, bigger capacities,
less chance of leaking and the charging circuit is not located in the
battery. No heat transfer or buildup.
-
Basic lead acid battery technology has been around the
longest of the chemistries.
-
Many different charge methods have been used.
We use the best. OUR CHARGER is a regulated
two stage charger. These don't let the voltage climb higher than the
trickle charge voltage, so they can be also be used to maintain a
battery. This is the newest technology that brought the SLA back. We use a
very sophisticated charger that high speeds the charging rapidly about 50
min per amp hour thus a 5 Amp hour battery is about 250 minutes or about
four hours.
-
Our Chargers have circuitry that is set for the maximum allowable
charge voltage, but has a current limit to control the initial absorption
current and produce's a very nice charge. The upside is, this type of charger can both charge at a reasonable
rate and maintain the battery at full charge without damage. Indefinitely.
-
We need that to cover the five to seven year lifespan of the battery. You
take care of it, it takes care of you. Because our battery is larger it weighs more. Would you
rather carry twenty five AA cells, four Bantams, four of the Dogs or two
Quantum ones instead. It weighs slightly under 8 OZ heavier than a
Turbo.
TO TELL THE TRUTH - The Beer
Comparison.
Some of you won't like this...Batteries come in different price
ranges, qualities and integrities. In batteries simply saying "you get what you pay
for" means nothing. You get what was put inside and NO MORE THAN what you
paid for. It's not like buying milk, your milk vendor sees you once or
twice a week. Your battery guy sees you when you need him. By the way, I
lost a friend to drinking milk a few years ago. Unfortunately the
cow fell on him.
Perhaps beer is a better example. Most have more concerns about what they
stick in their gut than the brand of battery they stick in their 400-500
dollar strobe. It depends on the integrity of the builder and then the
integrity of his vendors. Whether you know it or not, the manufacturer can
print anything they want on the outside. That's the part you get to
see. The testing standards used to achieve "incredible results" are
usually about as accurate as the testing individual who works for the guy
selling the batteries. Sorry, that's the game in a totally unregulated
business.
Example: Those 2500 - 2700 AA MAH batteries attained their numbers from a
three or ten amp hour
draw. Think of it as a large bottle of beer. A quart bottle. You
have two drinkers. One guy gulps it down in a 1/2 hour. They rate
him as a 1/2 GAH ( Gulps an hour). Drinker number two sips his beer and
takes two hours. (2/2 GAH) Sounds more impressive. It's not.
The sipper has a lower draw or drinking speed but the capacity is the
same. Remember a business with no regulations. A 2100 mah battery at a
three
amp drawer can be the same thing as a 2700 mah battery at a six amp drawer.
Numbers mean little in milli-amps. It's the drawer that tells the truth.
Today, you build to the profit margin, just as Wal-Mart goes to it's
vendors and says "that's all we'll pay", you figure out how to make it
cheaper. They, the vendors go to China or elsewhere where cheap labor is
available and the vendors say this is all we'll pay.
The internal boards and workings, of most battery operated products,
the batteries themselves, even cases are made all over the world, China in
particular. Mine come from Denmark. They were stronger than the
Chinese ones. And now the game is taking Chinese stuff and assemble
it in Mexico so that no tariffs are paid. So it might mean made in Mexico
by way of China or is it the other way around?
The only thing I can control is to
buy the best reputable components I can find and it's getting harder.
I am willing to buy better supplies and I have held pricing though
my costs have gone up. In the beginning one vendor sold me a
bunch of RCA jacks that were supposed to fit a .240 (24/100 hole or
slightly under 1/4 of an inch). The first batch came in .218 to
.245. Some too big, some too small and they broke. I had to replace
several units when they snapped in the field. I use the strongest
RCA plug made now. I'm paying four times as much to
get quality parts now and learned a valuable lesson. I do not listen to
vendors anymore. And I overbuild.
MY PACKS ARE MADE TO POWER
-
Regular
on-camera flashes like a most Canons or Nikons
-
Really outstanding with
the Vivitar 283/285/285HV
whether on camera, bracket, or in a dual setup for a light stand.
-
We have pros in the field who have captured 1500 images
doing variable flash fill for outdoors sports.
-
They are perfect for the remote Canon and Nikon strobes where you want your recycle times as
fast as the mains.
-
Dennis Reggie is mounting
multiple Canon strobes on a light stand with wireless at Weddings.
-
You can use two Vivitar
283/285's with a Wein slave or peanut in an umbrella. And build the whole
thing for a fraction of the Canon cost.
-
Each pack can power two
strobes with the optional second port into an umbrella or softbox or two
strobes floor mounted for backgrounds illumination of large churches or
areas displaced at 10 degree angles.
-
Or two FONG Tupperware's,
side by side, someone suggested this. I have no clue what that
would do.
-
You can also tape it,
glue it, Velcro it into position, who cares. Its' affordable. Use it on
remote powered setups. The battery has 90 days in range at about 90+% off
the charger. Try that with NIMH. With real HD components,
Fused breakers and switches. No idiot lights, no power robbing
circuitry.
THE SMALL PARTS - CLIP JOINT
I use the Super
Heavy Duty BELT Clip.
I have had competitive packs just slip off my belt because they lie
flat on your waistline when you sit down.
Cheap clips bend and lose shape. and one will finally realize what
holds their 200-600 dollar device in place. And we all know St.
Murphy-Lawes, the Patron Saint of Photographers. If it can fall, it
will, and usually during the Wedding and cease to function.
So I contacted
Beau Bennett of the
www.theclip.com
. He knows
the CLIP
business. We tested it and it was the only product that worked.
All of my gear will be made using his products.
The
"Ultra Clip" is designed to help protect high-end,
electronic devices from loss or breakage.
It is a Locking Belt clip, that
means when you unlock the safety it will only come off if rotated to
a certain angle.
This two step prevents fall off. So it takes two
motions to remove the pack.
It also allows the pack to rotate
while on so if you sit down, the pack gets out of the way, but
doesn't head off on a trip of it's own.
It fits snugly on most 2" Belts. We recommend you use a
separate black 2" belt so that the weight of any pack will not lower
or drop your pants thus preventing "photographers crack, a socially
debilitating scene similar to plumbers crack".

PRIVACY
We have a firm commitment to privacy. Whether
you are a recent graduate of the Raeford State Prison System or never told
your wife about those nude pictures of your ex you kept, what gets said
here, stays here, just like in Vegas.
Cookies are not used, we eat cookies. NO pop-ups, no ads, no spy wear, no
ladies wear. We just make Gearhead stuff. We do not sell lease
or transfer any information that comes to us like your name, arrest
record, IRS info, email, or address. We do not solicit any
demographic information other than the occasional request for a good
restaurant or shooting location (photographic) in your area. We travel a
lot and once asked a fellow for a good shooting location in his area and
he recommended "the projects".
It's simple, the data you submit about what
you shoot with and specific equipment tells me what to design around. For
example many are using the Vivitars in 283/285 as backups and fill lights
on light stands with umbrellas. So many, it is the number one
selling strobe of all time.

BEST OF THE OTHER QUESTIONS
I understand that the Metz batteries are 8-9 volts
(approx.) and the normal batteries are 6 volts (approx.).
ANS: Both batteries are normal, it's just the manufacturer made them on
either a 6 or a nine volt platform or setup depending on how many AA cells
went on board. If it takes four AA cells to run it it's a 6 volt platform
and if it takes 6 AA cells to run it it's a nine volt platform. I make
chargers and intelligent battery packs for both.
If I get a higher powered battery for the Metz with the optional
additional outlet, what could I expect that to do to the recycle times?
ANS: The pack I build has had good recycle times (Full
dump-3-3.5 sec) A lot depends on the age of the capacitor and condition of
the strobe. In addition "faster" reaches a peak based on the fact that
though a capacitor is like a black hole and takes it all in, it to has
capacities and things like 22-24 gauge wiring in some of these strobes just
don't handle overloads well. Years ago we ran higher clock speeds in
computers and while the results were minimally greater the blow-ups exceeded
the expectations. I wish everyone would take apart their METZ, NIKON
and CANON products and saw how much is crammed into the space and how weak
the wiring really is in these things before they overloaded them.
One of the converted Vivitar flashes I have has been powered by a
Quantum Turbo since new, so I'm sure it would take the 8 volts to "power it
up."
ANS: Wrong. That Turbo is pushing 325 volts into the Vivitar since
the Turbo has it's own fly back transformer and sends the 325 direct into
the capacitor of the flash. This is the part I DO NOT fool with.
I feel certain the other one ARMATAR 100-200 altered Vivitar
will, could, or may take more than 6 volts as well.
ANS: Possibly, there were many conversions done in those days. At
least four guys in NY made the flashtube and capacitor changes and variants.
Armatar probably being the most famous and prolific. Unfortunately un-inventing something from years ago has to be done with
someone who works on one-offs. I do when not busy. (REPEAT when not
busy and looking for a challenge)
Think of this: The original inventor (ARMATAR in NY) doesn't even
fool with them anymore.
Last time I spoke with a few customers, they had trouble with
getting parts and the original batteries have undergone changes so the packs don't fit the
battery and have to be altered. Makes sense for me to stay clear. Just use
the Turbos.
Is there a watt-second output reduction if the voltage is less, or
does it just take longer to charge up?
ANS: Both, either or it won't top the capacitor at all. Many nine
volt models are really 8.4. Many variables here and sooner or later you have
to upgrade. For me it's too time consuming to work on older gear
because of the parts and supply side. I'm sure there are those who
enjoy retro work but lessons in life have told me many times you are never
reimbursed for what you do and from a prudent business standpoint, "these
projects are best avoided".
Is it possible to "gang" two of the regular batteries together to make
a 12-volt power supply if any of the flashes I have require that?
ANS: YES but it's easier for me to just build 12 volt packs, I have
access to 5000 different batteries, from my distributor at competitive
pricing because of the organizations I belong to.
The SB-800 also uses a Quantum Turbo and takes five (5) AA batteries.
If it takes 5 batteries at 1.5 volts each - then does that mean the flash is
7.5 volts?
ANS: I wouldn't use that for all the t-balls in China, sure pure
way to blitz a SB-800. Nikon made the five pack to give you 5 x 1.25 or six
volts with NIMH. The 7.5 gets cut back by a resistor. Now you add the Turbo
to the mix... Where does the heat go? Remember Nikon does not make a HV
pack, the make a AA add-on. So you are combining an overload and Nikon knows
it and charges appropriately (179.00) when it blows.
I just checked the Quantum site and it says the Turbo Compact provides
6, 9 and "high voltage" output. THIS IS CLEARLY OVER MY HEAD.
Lead Turbos are 8.4 batteries (Lead Acid, the same I use) the NiMH are
higher. that have a
huge computer board inside that contains several resistors to down step the
8.4 down to 6 volts....leave it at 8.4 which they call 9 volts and a
transformer that steps it to 325 for HIGH VOLTAGE. The actual current is
controlled by what cable you hook up . The cables have six or seven ports
and create various combinations depending on which two wires are selected.
Thus they are expensive, hundreds of solder joints and when wet will fry...
I will substitute simplicity to complexity for the convenience of ports I
will never use.

Why USPS instead of UPS
or FedEx?
We ship via
the United States Postal Service. We get excellent flat rate rates
for two day delivery regardless of weight for the size unit we ship. It is
25% cheaper then UPS and FedEx. The insurance is cheaper and reliability
has been 100%. In addition there are other cost savings on boxes and
materials down. So by keeping my costs down, it keeps your costs down.
Our standard package weighs almost six pounds, ships in two days and with
$200.00 in insurance runs about $12.50 anywhere
USA.
Add $5.00 for Paypal and 2.50 for shipping supplies, gas, and tape and I’m
lucky to break even on shipping.
Sometimes we will ship to you before your drop shipped cable arrives.
For those
drop shipping or sending me their cable for upgrades. This is a logistical
situation involving how many units I wish to store before I get them to
the post office waiting on cables to be modified. It also means more open
boxes waiting to ship and may cause mix-ups so we may ship you in two
packages. I will not charge extra for the second package if I choose to do
this.
Here are the reasons mostly aimed at keeping costs down. This
means lower for you by taking advantage of the pickups and shipping
benefits of the United States Postal service.
The Post Office does pick up and I have to make sure they grab the
packages on schedule. Frankly
the increase in gas
prices means elimination of daily trips to the post office, I save gas
whenever I can and so should you. Postal service pickups just like UPS and
FedEx are time framed and not specific. I’m semi retired so only working
80 hours a week, I have to watch my time. Also a PJ assignment can slow me
down. This allows during the busy season like May June to flow smoother.
When the cable arrives for those using the free upgrade, it will be turned
around in an hour and shipped First Class to you same day in an envelope
suited for mailbox delivery. Those go daily from the drop.
Very important…these
chargers I use, especially the the standard charger, are considered
“Intelligent Chargers”. They are the forty to 100 dollar option
charged by the other guys. They differ from simple idiot box “wall warts”
that are usually furnished with most high end packs. They constantly test the status of the battery. With that
said, when the battery is not in use and we are speaking of the Black Box;
it can and should be stored on the CHARGER! It will not overcharge and
will keep the battery topped automatically. Under NO circumstances
leave the depleted battery in that state. Or, you will wind up sending
it to me to re-power it. Simple rule…If it’s not busy shooting it
should be on the charger. This is what allows the unit to last five to
seven years. It is designed to work this way. the Tuxedo of smaller
capacity charges in an hour or so and should be charged after use and then
tweaked say once a week.
UPGRADES
Upgrades available: 03/27/06 - New HD RCA jack available. Send
me email, and picture of top of your unit and we'll schedule an upgrade.
No charge for upgrade, shipping is $12.00 Paypal USPS Priority Only
CABLES FOR YOUR BATTERY PACKS
So that you may connect your battery pack to your flash. We
do not furnish those
but we will assist you if you need help.
ORDER EARLY THE BLACK BOX
WE ACCEPT CHECKS, (slow), MONEY
ORDERS (faster)
and Paypal (sometimes shipped in 24 Hours when it's slow and that depends on volume and hangovers, floods,
colds, hurricanes, bee stings and haircut
appointments and the occasional assignment) In other words I get
them out as I can based on supply and demand. Because you waited for the
last minute to order doesn't mean I need a heart attack or stroke on your
behalf or to stand on line at the post office for three hours during the
Christmas rush just to log an Express order. When I'm on line, I'm
not building someone else's pack. I will however try to get things
out expeditiously.
