Portable Watch Charger, 6000mAh 2 in 1 Portable Charger for Galaxy Watch 8/8 Classic/7/Ultra/6/6 Classic/5 Pro/5/4/3/Active 2, for Galaxy S25 Ultra/S24 Ultra/Z Fold7/Z Flip7/S23/S22/S21

I am absolutely blown away by the value of this portable charger. I originally purchased it with the simple goal of charging my Samsung Galaxy Watch during weekend trips, but I never imagined how indispensable it would become.The 6000mAh capacity provides more than enough power for multiple watch charges (I've never gotten close to exhausting it), but the real surprise was the handy USB-C output. It has saved my phone from dying more than a few times, essentially acting as a two-in-one power bank.However, the absolute best feature is its brilliant design for in-car watch charging. On long road trips, trying to keep my watch on a standard charging pad was impossible; it would slide off with every bump and turn. With this charger, the problem is completely solved! I can tighten my Galaxy Watch strap loosely right around the body of the charger, which holds it perfectly and securely in place while it charges. The convenience of this cannot be overstated.If you travel or spend a lot of time on the road, you owe it to yourself to get device as an essential piece of kit. It’s versatile, thoughtfully designed, and solves a major annoyance of charging on the move. Highly recommended!

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.

This charger works great with my Galaxy Active 2 watch and my Galaxy phone. The unit is a convenient size to throw in my purse and charges much faster than I expected. VERY PLEASED with this purchase!

Works nicely. Great for charging my watch, but can also give my phone a boost when needed.

Wow,wow this charger saved me many times over in europe when my cell and phone were running out of power and I was lost. Extremely hand and robust. A must have when traveling. I strongly recommend works well with Android and Apple watches. :))

I often find myself away from my watch charger, and that can spell a problem on occasion so I endeavored to find a solution, but had no idea that portable watch batteries were even a thing...but boy am I glad I accidentally found them. Now typically I wouldn't think twice about having one of these, but since Samsung removed our ability to reverse charge our Galaxy watches using our phones, this kind of became my go-to for topping off my watch while on the go.It really does the job, too. It has a fairly impressive 6000 mAh battery - which is actually bigger than the one for my S25 Ultra phone...meaning it'll top off my Galaxy Ultra several times over before needing to be recharged. The additional advantage of this battery in particular is it also comes with a built-in cord that I can use to charge virtually anything with that is USB-C compatible...and since these days almost everything is slowly migrating to that, means this will so be able to charge almost everything I need.It is not compatible with charging an apple watch though, no matter how similar it may look. Apple has made that tech proprietary and well, as is often the case with Cuptertino, they march to the beat of their own drums - and that's okay.Either way, if you need something convenient that will help keep your devices charged for several days, this really ought to do the trick and solve multiple problems all by itself. I lost my old one, and bought another - yes, I like it that much.

I didn't have any complaints initially as it was small and easy to carry around but then it just abruptly stopped working after a little over a month. The blinking lights to indiciate power on and charging levels won't turn back on and I am back to square one.

I am using very long time.Very good quality. very compact and powerful
