U2O i-UP 5400 Universal External Battery (Lithium ion battery 5,400 mAh) is a very useful power backup which I am using to backup my Archos 405. Which is fitted with a Helmet (or rather Head -- saves any confusion) cam, that attaches via an Archos DVR Travel adaptor. This has a 3.5mm 5volt input to which the external battery will attach, if you used the correct adaptor from the selection included with the kit. Please see video.
were did you get it?
