Haven't seen this mentioned around here...but bescor makes a family of batteries
with a cigarette lighter adapter built on...all you have to do
is plug in your JB3 cigarette lighter adaptor into
the battery and walla, ready to go.
there's a few flavors of these...
here's a pic:
you can check out the family here:
http://www.bescor.com/Batteries/12v_shoulder_packs.htmthe prices on that page are a bit higher than you can
find them for elsewhere...do a froogle search
and it'll show all sorts of vendors with better prices.
we have a couple of the battery packs here at work (each belt holds 4 batteries
for our onboard camera lights) and i just tested the JB3 lighter adaptor
and it powered up just fine.... this is perfect for morons such as myself
that don't want to have to rig up anything! just charge, plug and go!
some of these packs come with a charger as well...
just a heads up!
i am ordering a 12aH battery now!
