[QUOTE="Wolla, post: 752970, member: 664"] This little amp uses around 17mA at 5V, so theoretically can run non-stop for 14 days on one charge of my 660mAh battery power banks. Crazy stuff. This is at normal listening levels, not disco loudness. It uses this amount of power even when not playing any music at all, just being on. It does use more power once I go loud :angrywife: [IMG]http://a68.tinypic.com/105tqgn.jpg[/IMG] [/QUOTE]
