Ok so where does an idea come from anyways? its the only important question & the most difficult. i guess i'd have to say it was prompted by looking at these half-dozen projects: *aaron dunlaps 9v usb charger *another 9v + 7805 usb charger (instructables) *jason streigel's 9v+7805 usb 'battery' (hackaday) *ians firewire switching charger. This is a lithium-ion charger for lipo batteries. circuit schematic shows configuration for charging single 3.7v lipo battery but voltage can be set to charge several batteries in series.. All energizer® batteries provide long lasting power to keep all of your devices ready for action. rely on energizer for the battery types you need!.

Dc to dc battery charger - learn how to construct a simple


This is a project of a mini usb car charger circuit. the circuit can charge usb devices with car battery.... What i really find annoying is that on all the commercial solar usb chargers i see their internal battery is only 1000 ma. that isn't a lot. a rechargeable aa battery has between 2000 - 3000 ma of current in it.. Automatic battery charger automatically starts the charging procedure when battery voltage drops below a certain predefined value and stops after the voltage has risen above the maximum allowed value..
