The Wire-free Qi charger is an excellent example of a bridge between tomorrow’s charging technology and today’s phone.
It includes a standard Qi pad that is compatible with many modern phones including those by Apple and Samsung. The pad is powered by a built-in rechargeable battery that can provide high current. The battery is, in turn, charged using the built-in Wi-Charge wireless power receiver.
The result is a phone charging solution that is suitable for tables that are not connected to wired electricity. See the demo video here
