So wildly convenient.
This thing is so wildly convenient. Ever since Samsung removed the powershare ability to charge it from my phone (due to a more curved back-plate on the watch), I needed another method to charge my watch on the go. This does the trick quite well. I may buy another just to have it on hand in my travel bag.

Will not charge Samsung watch when connected to the phone
Will charge Samsun watch from an mobile battery or wall charger but not when connected to the phone. Samsung original charger will do so. I purchased it to be in my bag without needing to have a battery with me.

It’s a much better keychain than charger.
This charger is garbage. Doesn’t charge my Galaxy watch ultra like… at all. Doesn’t matter what I plug it into. The magnet is the weakest of all. Bought cuz it looks convenient. Function? Not great at all. It’s a good idea and had it worked like… at all. One star because I can’t submit 0 starts. I’d have given points for ingenuity.

Just Okay
This charger is just okay. It is portable, so if that's your top priority, this could be an okay option. However, the magnet is not that strong, and it takes forever to charge with this thing. With 76% charge on my watch, it takes an hour to top it off. When I connect my watch to my stock charger, topping it off takes 36 minutes (43 if in my car). Either way, it takes longer to charge, and because the magnet is so weak, it easily comes off the watch if you are moving. In short, I would probably recommend something else.

Nice alternative
On a trip I almost lost OEM charger that came with my Galaxy watch and in looking for a spare found this little charger. Small enough that I can keep it in travel bag. I also like that in came with an adapter that allowed me to convert from USB C to one can plug into my backup battery.
