The Datexx SuperBattery is a hand-powered 600mA mega power battery that can be used to charge up to 1200 different devices, mostly mobile phones, MP3 players and digital cameras. The robust hand-crank device will give you 6 minutes of talk time for each 2 minutes of cranking time. A surprisingly efficient return for a little hard work.
The SuperBattery comes with an array of adaptors for charging the numerous supported devices. Alternative connection tips to support other devices are available directly from Datexx. The USB cable supports virtually any USB charging device. You can also charge the unit via the mains with an adaptor cable, useful for when you’re just setting out on a long journey.
A fully charged SuperBattery can give your cell phone 36 hours on standby and 5 hours iPod play time. Then of course you can top up the battery with the hand-crank. The SuperBattery measures 57mm x 38mm x 102mm, weighs roughly 170g and costs around $30.
