With the Belkin Boost Up Wireless Charger 10W, you can charge your Samsung or Apple smartphone extra fast wirelessly. This charger supports wireless fast charging for Samsung and Apple, among others, so the devices charge up to 2 times as fast. Wireless charging remains slower than wired charging. The charger is also suitable for all other wirelessly rechargeable smartphones. They charge at standard speed. You won't have to look for cables when you start charging, all you have to do is put your smartphone on the charger. Thanks to the anti-slip finish, smooth glass phones also remain firmly in place while they charge. Do you have a case on your phone? As long as there's no metal in it and the case isn't thicker than 3mm, that's no problem.
Note: wireless charging doesn't work well with cases of 3mm or thicker, or with cases that contain metal.
Wired charging is always faster than wireless charging.
