Samsung Ultra Fast Wireless Charging DUO PAD - White

i used this fast wireless charger with my then new samsung s10 plus. i now use it with a s21 ultra, galaxy 45mm watch3, and buds pro.. using my now 2 year old fast wireless charger duo pad, the buds pro and the new s21 ultra charge quickly and perfectly on this charger. my galaxy 45mm watch3 charges equally as well on the wireless duo pad. all i do is center the watch on the small pad to make sure the charge light for the pad is steady - if off center the charge light will blink and the watch will further discharge. the large pad is only for charging a phone. although, the smaller pad will also charge a second phone. i use the fast wireless charger duo pad for just over an hour every night with my s21 ultra and galaxy watch3.
