Excellent Portable Charger for Galaxy Watch 4
My husband and I each have a Galaxy Watch 4. We purchased 2 chargers. The portable chargers worked fine, both while the chargers were plugged in and charging and while they were unplugged. They charged the watches quickly and without any issues. We had overheating issues with a different non Samsung charger. It seems that we can get 2 watch charges on a full portable charger battery. The portable charger recharges quickly using the USB cable provided. The charger is small and lightweight.

Excellent charger for your watch
This works great! I bought it for a trip and it was just perfect. Small enough to fit in my carry bag and it would recharge my watch quickly and easily. It holds a charge nicely and recharges quickly.

I mean it charges your watch , great for the office or when your away from home.
I mean for me this is roughly a 3.5 to 4 star product. The charger works don't get me wrong, the main issue with me is that I don't have the OEM bands, I have sort of like a G shock like case + band on it right now that limits the option on charging my watch. My issue with this charger is I expected it to have a magnetic charging area but it does not which mean I can't throw it in my lunch bag, or have it to the side in my car to charge. As the charger slides off. I basic thought this portable charger was magnetic like the cable. So far I have only used it 3 times and in those times the charger kept sliding off pausing my charging, had to use two hair bands to hold it together to ensure it could fully charge my watch. Not sure if this is normal? Or if I maybe got a defective model? Heat level - notice it did heat up a bit when charging my watch, and slight heat when the bank was charged Durability- seems to be reasonable durable as it is made of more stiff plastic, doesn't feel flimsy. Power - usually takes a bit more of an hour to fully charge your watch, shows roughly 1 hour & 10 minutes I mostly try and top off my battery when at work or when driving before I hit the gym. But because of the lack of magnets on the charger it tends to move alot and pause the charger, item still works as intended hence why I gave it a 4

Favorite gadget this year
This is probably going to be my favorite little tech gadget this year. This does work with my galaxy watch 8 classic in which I'm so happy for since now it's not possible to charge the watch on the back of your phone anymore. I have attached this to my Keychain so that it always stays with me when I go out. Another positive is that I no longer have to worry about packing my watch charging cord because if this needs to be charged and my watch needs to be charged, I can charge this device and my watch at the same time. Yes it does take longer to charger the watch with this, but just knowing that I dont have to worry about having a dead watch is worth it to me. Since I've had it, I haven't noticed any issues with my watch heating up or the battery deteriorating. A must buy for galaxy watch 8 series owners since we cant charge the watch with our phones anymore and some people like me, don't want to carry 2 separate cables.

10/10 would buy again!
**5.0 out of 5 stars** This little thing is now permanently on my keychain — absolute game-changer for Galaxy Watch owners Reviewed in the United States on April 2, 2025 Verified Purchase I picked up the Phelinta 1800mAh portable charger with keychain on Amazon on March 6, 2025, after missing too many workouts because my Galaxy Watch 8 Ultra died mid-run. I already own a couple of big power banks, but I wanted something I couldn’t possibly forget at home. This tiny charger has exceeded every expectation. **What I love:** - It’s legitimately keychain-sized. The whole thing (charger + built-in keyring) is smaller and lighter than my car key fob. I’ve had it dangling from my keys for almost a month and I forget it’s even there until I need it. - Charging speed is excellent. It takes my Galaxy Watch 8 Ultra from 15% to 100% in about 65-70 minutes, and it can do it twice on a single charge of the charger itself. My Watch 7 and wife’s Watch 6 Classic charge just as fast. - The magnetic puck snaps on perfectly every time — strong enough that I can dangle the watch from my keys while it charges and it never falls off. - Four little LED lights show remaining power clearly. Green = 75-100%, blue = 50-75%, etc. Simple and useful. - Comes with a short built-in USB-C cable hidden in the side, so you’re never hunting for a cable. - Build quality feels premium for the price — matte soft-touch plastic, no creaks or sharp edges. **Real-world use:** - Saved me on a 3-day work trip when I forgot the wall charger. - Charged my watch fully during a half-marathon when I started at 22% and finished with 95%. - My teenager now borrows it constantly for his Watch 5 — it’s become the family “watch resuscitator.” **Minor cons (barely worth mentioning):** - The keyring part is a little stiff at first, but it loosens up after a few days. - If you have a thick protective case on your watch, you might need to pop the watch out — but that’s true of every magnetic charger. At the $28 I paid, this is one of the best Amazon impulse buys I’ve ever made. If you own a Samsung Galaxy Watch and ever leave the house, just get it. You’ll use it way more than you think. 100% recommended.

I love my Samsung Galaxy Active 6 watch but I often find that the battery dies on me before the day is up. This nifty charger is the perfect solution when I need to top up my watch battery on the go. It is super slim, small and light (about the size of a traditional matchbox) and really easy to use. Most importantly it does what I need it to do, which is to charge my watch quickly so that I can use it till the end of the day. Charging the watch from my phone is slow and inefficient whereas this charger does the job much much better. It is not cheap but it fits my needs perfectly so I feel it is value for money.

Cumple muy bien como cargador de viaje, va muy bien con el Samsung Galaxy watch 7

As you can see in the pictures, it is very slow compared to the original charger and about the capacity, I don't know what to say, after I unpacked it and turned it on for the first time, 3 out of 4 LEDs were on, after charging the watch battery 1% for about 1 minute, it was left with 2 LEDs on. It's up to you whether you want to buy it or not, but I, knowing what I know now, wouldn't buy it even if it cost 10% of what I paid for it.

reicht für etwa 1,5 Vollladungen. Praktische Notlösung wenn kein Ladegerät in der nähe ist.
