Continuance AA Battery Packs USB Port

Continuance AA Battery Packs USB Port: "

'Continuance' tries to combine AA and USB into one

Continuance is a battery that can power pretty much anything. It’s a rechargeable, AA-sized cell with a USB port in the side. The concept — designed by Haimo Bao, Hailong Piao, Yuancheng Liu and Xiameng Hu — is meant to make it easy to power any device, whether it takes batteries or has its own USB port.

But can USB and AA exist side-by-side? Leaving out the fact that the extra circuitry takes up precious power-storing space inside the cylinder, can a 1.5 volt cell provide the 5 volts needed to ive up to USB spec?

I don’t know. I guess you could certainly transform the output by upping the voltage and lowering the current — V=IR, after all. But then, P=IV, which may leave us struggling to get the 5 watts of power needed for many USB devices to function.

But what do I know? I’m no electrical engineer — I use my “soddering” iron to brand grill-marks into my microwaved chicken dinners, for God’s sake. Maybe this is a fantastic invention.
