SwanScout 303S - Samsung Galaxy Watch 8/7/6用ワイヤレスモバイルバッテリー

Overall, the power bank is OK. One major issue is that the magnet meant to keep the watch attached and aligned with the power bank is very weak. This makes the connection between the watch and the power bank unstable, so charging (power transfer) is not reliable.

SwanScout 303S - Power Bank for Samsung Watch

I have to say i am satisfied with the product. It is a little bigger than i imagined and it charges my watch (Samsung watch 7) a little bit slower to my liking. But is has helped very much because i dont need to think every day if the watch is charged or has enough battery. I recommend it. the battery is enough for 3 charges, possibly 4.

I've been looking for something with good build quality weight and battery life for a long time. I absolutely love the design and it's easy to throw into a bag backpack or pocket for when you know you won't be close to your home charger.

the battery on the samsung watch is decent, but it being a portable charging bank is a great plus. doesn't seem to get hot or anything folded up it can fit in a pocket, and easy to use. good overall product for the money.
