How about some portable power for your portable smartphone or tablet? The Etón BoostTurbine2000 is a small back-up battery that slips easily into a backpack or carryall. The battery's USB port makes it compatible with the charging cables for most any electronic portable.
The hand crank fits right into the body of the battery when not in use, and swivels out when you need to power up. Press a button on the battery to see the LED charge level indicator. The BoostTurbine 2000 has a durable, lightweight aluminum body and is completely self-contained.
One minute of cranking the super-efficient dynamo can generate enough power for your phone to make a 30-second call or send a few texts — handy in an emergency when power goes out.
And when the BoostTurbine 2000 is fully charged, it can fully recharge most smartphones. An included micro-USB charging cable lets you recharge the BoostTurbine 2000 through your smartphone's AC recharger.
