With a wireless charger, you can charge your Samsung smartphone from the S20 without cables. Put your device on the charger and it starts charging by itself. With a 15W Samsung charger, you can charge your battery the fastest. With 15W, you can charge your S23 in less than 2 hours. With our other wireless chargers, that takes about 3 hours. Cheap wireless chargers from the supermarket or budget websites can even take 4 or 5 hours. On a charging dock, you can charge an extra smartphone, your Galaxy Watch, or your earbuds at the same time. Put them on your wireless charger next to your S23, S22, S21, or S20, to charge all your devices easily without cables.
