Survive with Sony's hand-crank USB charger

How would you power a smartphone or other USB without a power outlet? Sony has an answer.

One possible solution to resurrect a dead phone resides in Sony's latest portable CycleEnergy USB charger, with a built-in hand crank, due out in Japan on 20 June for 8000 yen (AU$100).

The modular charger (the CP-A2LAKS) features a dual-port unit capable of charging two USB-equipped devices and a built-in 4000mAh battery, chargeable via AC power.

A Sony press release stated that the large battery capacity within it can deliver enough power to charge a smartphone twice, with an additional reference noting that it would take about two hours to give the Xperia Acro HD smartphone a full charge.

As for charging from hand-crank power, don't expect any miraculous numbers; it takes about three minutes of cranking for one minute of call time, and five minutes of cranking for one minute of web surfing. Those seeking a full charge would need to crank for many hours. But in a disaster scenario, where power no longer exists, that doesn't sound so bad.

This is neat, but it's no alternative to real progress in battery technology... Stop adding "features" in our smartphones and start giving us batteries with 2 days of HEAVY usage!
