Pretty well designed little battery. Strong electronics for the size of it. Test results handle 5V over 3.3Amps no problem (exceeded 3A /15W rating) 9V handled 2.5A (exceeded 2.22A at 9V -20W rating) at 22.5Watt in the test 12V output was 1.89A. (Rated for 20 watt at 1.67A) also went to 22.5 watts in the test. + has built-in bidirectional USB-C port (charges and discharges) + has built-in bidirectional USB-C cable as well (charges and discharges) + clip on the end looks strong + Power button on the same same side as the LCD is visible and better than on the side somewhere + Has a full 3 segment LCD display + The writing on the back is large enough AND clear. That's useful and uncommon. + Built-in USB-C cord has an unusual weave surface and hides away easily. + Real output specs are printed in the back, 5000mAHr at 3.6V = 3100mAHr real output after losses. Minor cons: - Display can be hard to see which side is up... is that 52 or 25% - No USB-A port, but that's expected in a charger this size. - The black texture surface over the LCD display makes it darker and a bit blurry. Overall one of the most compact, well designed, strong little chargers so far and it does Magnetic charging also.

I've probably got way too many power banks, but it was hard to resist this little guy - especially because my wife is constantly struggling with ways to charge her Apple Watch when we're on long hikes in the backcountry. She frequently uses GPS tracking to log our progress, and the watch can't keep up with a full day hike. We carry power banks and cables, but it's always a bit of a pain to dig into hip belt pockets and extract the whole mess. This is WAY simpler: not only does it have a built-in wireless charging pad, but it's small - small enough to fit into a front pants pocket, or hold easily in your hand. The 5000 mAh battery capacity isn't much if you're also planning to charge your phone from it (which you can do, thanks to the really handy built-in USB C cable), but it's more than enough to charge a watch a dozen times or more. The battery percentage display is super useful, and the charging speeds are just as fast as advertised. Really happy to add this to our backcountry kit. It'll probably replace a slightly heavier power bank, so net weight savings FTW.

This is an extremely versatile battery. I got this for the capability of adding a quick charge to my devices while traveling. Very quickly I found out that I keep this with me at all times as it is a great watch charger for my apple watch. I may be in the office or driving and I always have a watch charger with me. It will charge my Apple Watch Series 9 from 1% to 50% in about 30 minutes and this gets me through the day very easily if i forget to charge one day. The attached USB-C cable can be used to charge a device or charge the battery. Also the USB-C port functions the same way. Love this very small device.

This little charger is great, I’ve had my eye on something like this. My Apple Watch always dies when I’m out and about and I don’t have a charger. This is the perfect solution. It charges my watch in about an hour or so. It charges my phone a bit slower though, more like 3 hours. It has a key chain attachment, but it’s a little heavy. Only thing I wish it had is a lightning cable attached, but other than that I love it and highly recommend it!!

Easy to tote around as an emergency backup - not as easy as just carrying a cable of course, but if you’re somewhere without electricity this is a viable short term alternative. It charges my phone at about a 1:1 power exchange ratio (1% drop in the charger for every 1% increase to my phone) - I have a Samsung Galaxy S22. I got this specifically for short term use if I need an emergency phone charge in a blackout, and am satisfied with the product for this use. I very much like that I can tap the button to see remaining charge. I do like the built in cable, but it isn't easy to get it to STAY where it belongs. It pops put super easy which is annoying. There's no way provided to secure it other than to convince it that it fits in the groove.

I love this little charger! It’s compact but powerful, and perfect for traveling. It charged my phone from 85% to 95% in about 20 minutes, and out of the box, it was already at 51%. A full charge from 50% to 100% took about an hour, so expect around two hours from 0% to 100%—pretty much the same as my other portable charger. The built-in USB-C cable is a game-changer—no more carrying extra cords! But if you need to, there’s an extra USB-C port for another device or for recharging the power bank. The Apple Watch charger on the front is a nice extra bonus, and I love the small LED display that shows the remaining battery percentage. It’s small, lightweight, and super convenient—an easy 5 stars from me! Perfect for anyone who needs a reliable, all-in-one travel charger. ⚡🔋⌚

I absolutely love this portable power bank! It’s tiny, lightweight, and incredibly convenient—small enough to clip onto my bag but powerful enough to keep my iPhone and Apple Watch charged on the go. The built-in USB-C cable and wireless watch charger mean I don’t have to carry extra cords, which is a huge plus when traveling. The fast charging is impressive, especially for my Apple Watch, which charges way faster than other portable chargers I’ve used. The battery percentage display is another great feature, letting me know exactly how much power I have left. For such a compact size, the 5000mAh battery holds more than enough charge to get me through the day. It’s a must-have for anyone who wants a reliable, portable, and multi-functional charger.
