Use the charging plate only with the supplied power supply.

1 Connect one end of the charger cable to the power supply.
2 Plug the power supply into a wall outlet.
3 Connect the other end of the cable to the charging plate.

You can keep the plate plugged into the wall outlet even when you're not charging

your phone. The plate uses hardly any power when not charging.

Switch off
Disconnect the power supply from the plate, then unplug from the wall outlet.

1 Make sure that there's nothing on the charging plate.
2 Place your phone or other compatible device on the charging plate. When the

white indicator light goes off, the battery is fully charged.

It's normal for the plate and phone to get warm, and they may get even warmer if you

use your phone to, for example, stream music while charging.
