Portable Watch Charger, 6000mAh Watch Charger for Galaxy Watch 7/Ultra/6/6 Classic/5 Pro/5/4 Classic/4/3/Active 2, 2 in 1 Phone and Watch Charger for Galaxy S25 Ultra/S24 Ultra/Z Fold6/Z Flip6/S23

This has been the best and most handy battery to have and has lasted so well, while still out-performing others i've tried. It works great with my Samsung phone and watch, and I'm even able to charge my watch AND my phone While it's plugged in, essentially keeping it charged up and ready to take in my purse for a backup. I have used it to operate an inflatable costume as the battery source for the fan and it performed marvelously. I have used it to charge a Bluetooth speaker out in the field. I have even used it as a temp power source for my laptop in a pinch. When it/if it ever dies, I will happily buy another. Mine has lasted remarkably well and it's so small and easy to slip in a pocket. This is a very good value.

Bought for my husband and he loves it! It forgets to charge his watch at nighttime a lot so it’s great he can take out this little portable charger and charge it easily on the go. Battery works great last along time on a single charge. Great value

Works great with galaxy watch

Absolute perfect solution for charging your watch on the go. I can not stand having 12 charging cables and this makes charging my phone and my watch simple and quick. Does not charge as quickly as the cord or stand at home but does the job just fine. Compact with cord attached to charge your phone as well you don't need a lot to travel. Simple easy and perfect for on the go.

I like that fact it is a 3 in 1 charger very conveinent and the size is great!

It does charge the 7U but not fast charge . From what it's showing it is about half the speed , double the time needed , of the 7 series puck and 15 watt (or higher) wall wart .I also like the usb-c cord so I can use it to charge my phone or earbuds if needed .It didn't heat up my watch after letting it charge for 5 minutes .It holds pretty well in place while charging due to magnet strength .This is a must have for those who need something portable to charge their Galaxy watch and phone .

bought this for my galaxy 7 ultra. I would not recommend this if you have a metal band on your watch. The magnet that holds the watch to the charger is very weak, like barely present. Far weaker than the OEM charger. Unless you can set the charger flat and place the watch on it, it will just slide off, making it very difficult to use with a metal band that doesn't open completely.

If you have a smart watch you can charge it & the device itself lasts around 4 years before the battery swells to warp the plastic on it.
