ChargeBite is a small device containing 3 x 30-pin connectors that you carry on your keychain. In case that your battery is depleted unexpectedly and you happen to have few friends with iPhones around. They can spare some juice to get you going without the need to find an available electric outlet.
It looks like you need 2 donors to work and the device only supports the old 30-pin devices.
You can pledge ChargeBite HERE!
