I've looked at many types of DVD universal batteries...but I'm confused on which ones have output to a Standard (female) USB connection...most I look at have female USB Input and Barrel type output connectors...
I want to power a 5th gen Video iPod with a Kensington 4 in 1 Charger/Pass thru dock (see below)...ditch the cigarette car charger bottom part and plug directly into a DVD battery...with as few adapters and cables as possible.

Or would it be difficult to build a RC battery sled and hook up a female USB cable? What voltage battery and any other circuits would be needed?
Thanks in advance.

to my knowledge there is NO dvd battery with a usb out
you need some sort of converter/voltage reg box in the middle
do you know the voltage a iPod runs on? i think its 5v (most usb stuff is)
you would be better off getting a battery pack made to go with the iPod imo http://www.circuitcity.com/ccd/productDetail.do?oid=197615&WT.mc_n=92&WT.mc_t=U&cm_ven=COMPARISON%20SHOPPING&cm_cat=NEXTAG&cm_pla=DATAFEED-%3EPRODUCTS&cm_ite=1%20PRODUCT&cm_keycode=92
but if you did want to use a dvd battery you need a voltage reg between the battery and the iPod
you prob could also just use the cable that came with the iPod vs buying this cable you picture

Thank You!

AH....there's a reason I want to use this connector...as there will be a Micromemo under the dock (using line in with a Church Audio 9100 Pre)...and a power hungery Hard drive in the iPod above...Juice coming in on the USB cable...but no desktop/laptop in sight...

What do these folks know? A 9v battery directly wired?!? Cost $64.90 (http://home.swipnet.se/ridax/connector.htm) and ugly as sin to boot... :o
There is a 12v firewire power connection shown on the 30 pin out here... (http://ipodlinux.org/Dock_Connector)

Perfect...the lenmar is the very edge of the low end power wise...but at that price I can have two for backup...Thank you.

Check out this one too... I think you feed it Alkalines, but at $9.81 it's worth checking out.

There are specs regarding power supply over USB, and they aren't big. I think it's 500ma max.
I have a thing similar to this for my iriver H120. Works great. What I do is start with a fully charged iRiver, plug this in right off the bat, and this will "try to keep it charged", and mostly succeed. It will last all day this way. But if I run down the iRiver and then plug in the external, that's a big much for it.
