How does wireless charging work?

You need two things: a device with wireless charging capability and a compatible wireless charger. Plug the charger into a wall outlet and place your device on it to power up. It’s that simple.

Want a more technical answer? Wireless chargers emit an alternating magnetic field via the transmitter coil, which in turn induces an alternating voltage/current in the receiver coil inside the device. But really, it’s simple.

Can I charge a smartphone in its case, or do I need a special case?

It depends on the device. Many newer-model smartphones can be charged wirelessly with any case on, but some older smartphones require a special device-specific wireless charging back cover (sometimes called an inductive charging cover). You can find this information in your device manual。

How do I set up wireless charging?

Despite the name, there is one wire involved: You must plug the charger into a wall outlet. But there’s no wire between the charger and your phone. Just place your phone on the charging pad and watch your device juice up. An indicator light lets you know when it’s charging.
