A:AnswerHello. This charger will not work with the Galaxy A50 being that the device is not able to charge wirelessly. Thank you for reaching out to us. ^Kayla
A:AnswerIf the Galaxy S5 had wireless changing, then it would work for it. It will work with any phone, old or new including iPhone and Android that has wireless changing.
A:AnswerWiFi is not needed for the charger to charge a phone. If you're phone has wireless changing, simply plug in this wireless charger and just place your phone on top of it, wireless changing.
A:AnswerHello James, great question! This charger is Qi compatible meaning any Qi-certified products can take advantage of it, including your Samsung smartwatch. ^Elizabeth
A:AnswerIt's my understanding A50 phones are not equipped for wireless charging, so no, it won't charge this phone. No other wireless charger will work either.
A:AnswerShouldn't. Take it in to best buy and try it on their display charger. Or find someone with a wireless charger and try it. If it works with them, it will work with this one.
A:AnswerHello Jwsrewi9, thanks for asking! This charger is Qi compatible meaning any Qi-certified products can take advantage of it. Wireless Fast Charge is compatible with the Galaxy Note5 and Galaxy S6 edge+ and later models of the Galaxy S and Galaxy Note series. Standard charging speed applies to other devices including Galaxy S6 and Galaxy S6 edge. ^Elizabeth
A:AnswerYes as long as you don't have a protective case over the bezel part of the watch itself. It also won't overheat your smartwatch if you leave it there overnight
