It's amazing how no one thought of this before. I know I did a long time ago, but let's not talk about that. Thank you, Thanko, for your USBACH01, a standard AC adapter powering two USB ports on the unit, that can be used to charge or power USB devices such as MP3 players, light bulbs, fans or clapping monkeys, if you fancy those.
This is a good thing to take with you on those trips that last for more time than the battery life of your device. The device can only connect to two devices at a time, but I think a USB Hub (or two) connected to the charger would give you at least four more ports, not that you'd have those many USB devices that would run out of battery all at the same time. The best part about the USBACH01 is that it would cost barely Rs 500 (converted), which instantly makes it a valuable gizmo.
I bought this charger . Its great !!! the only down side is that retractable connectors are flimsy ! Its gives 500mA fot each USB.
