Strungup Posted January 9, 2008 Report Share Posted January 9, 2008 (edited) Ok today I bought a Lithium Polymer batt pack , ( I had a bunch of unused points on my Yodobashi Card) the " Powerbank Slim " model FPS440 Specs : Internal 3.7 volts 4,400 ma ... 4.4 amp hours folks. USB out 5 volts 1 amp ( I can confirm it , a lot of batt packs state that but are not anywhere near 5 volts , iPod packs are really bad about that) On/Off switch Input DC jack 5 volts A wall wart , that is World Voltage 100- 240 Volts 50/60hz here is a link , http://store.shopping.yahoo.co.jp/komamono/fps440u.htmlI have connected it to the RH1 , with a standard USB cable , and the RH1 lit right up , absolutely no problem .

Strungup Posted January 9, 2008 Author Report Share Posted January 9, 2008 Update: I have an older Kenwood DMC-F5R , MD recorder , DC 5 Volts input , and it doesnt like less, I can run it off of the Sony 4.5 volt , but it wont charge as well . The kenwood 5 volt supply charges it nicely , and I know how it acts when its is charging , if it sees to low a voltage it just wont charge. Believe me I have tried all kinds of stuff. I can run it from a USB to DC connector , but I have to be sure it is 5 volts . So anyway direct to the point , The Battery pack is now down to the last LED marker indicating almost empty , and the Charge indicator on the Kenwood is still going , what that tells me is that it is a REGULATED STABLE 5 volts out even when the internal voltage drops , . I mean I have the Litho almost drained , and it is stable at 5 volts . and will stay there untill it is empty . That is very very likable.

Levanel Posted January 16, 2008 Report Share Posted January 16, 2008 I still prefer an original external battery pack, no wires involved. Coincidentally, there is none for the RH1. Quote Link to comment Share on other sites More sharing options...
