The charger comes with a very thin adapter which you place on the back of the phone and all you need to do is place your phone on the pad and it will charge, wirelessly.
Technically speaking, the WildCharge adapter for the iPhone and iPod touch is actually integrated into a high-quality gel case called “Skins”, a gel covered product made of Thermoplastic Elastomers (TPE) material. WildCharge wire-free charging technology is located on the back of the case and all you have to do is slip your iPhone or iPod touch into the case and then drop it anywhere on the WildCharger charging pad. It’s that easy. A blue light on the left hand side of the pad lights up notifying you that the juice is pumping through your device.
