With the Samsung Duo Wireless Charger 15W Black, you can charge your Samsung smartphone extra fast and at the same time as your Galaxy Watch or earbuds. You only need 1 charger for your smartphone and your accessories. You can charge your Galaxy Watch with the special charging location on the right. This charger is only suitable for the Samsung Watch 3 and newer, and for the Active2 and Active, not for other smartwatches. Thanks to 15W fast charging, the battery of your Samsung smartphone is fully charged in no time. You can even charge the large battery of the S23 Ultra or S22 Ultra within 2 hours. With other wireless chargers, this takes 3 to 5 hours. Keep in mind that only the Samsung S, Note, Z Flip, and Z Fold series charge wirelessly. The A and M series can't do this.
Note: wireless charging doesn't work well with 3mm or thicker cases and with cases that contain metal.
Wired charging is always faster than wireless charging.
