AladdinPower is similar to the OLPC laptop charger design, in that it converts mechanical energy to electrical energy. However, this handheld dynamo is more of a hand grip exercise tool designed for forearm muscle workout, both in looks and the power one needs to exert to make it work. The reviewer notes that you’re likely to break some sweat as it takes a good number of squeezes to generate enough electricity to charge a portable electronic device. Besides that, the AladdinPower unit offers a narrow choice of adapters, and may require separate purchase of additional adapters for compatibility with a particular device. With any luck, the next versions of the AladdinPower will include more adapter options for portable devices.
