Many smartphones today come with a built-in option for QI wireless charging.
There are two alternate systems of wireless charging, of which QI is the most widely used (in all smartphones sold in Europe, for instance). All GRATEQ QI accessories are compatible with all phone models that use the QI technology.
1. Make sure that your phone enables wireless charging.
2. Choose your favourite GRATEQ QI Charging pad.
Please notice that the charging speed depends on the phone's charging capacity, so it differs a little between different phone models.
