The star of the show is the double leather and reinforced keychain loop, letting you clip it to your keys, bag, or even your dog’s collar (though we don’t recommend that last one). It’s travel-friendly to a fault—toss it in your pocket, and it’s ready for action when your watch starts begging for juice. The built-in USB-C cable is a nice touch, eliminating the need to carry extra cords.
With a 2,500mAh battery, this little guy can juice up your Apple Watch Series 10, 9, 8, 7, 6, 5, 4, 3, 2, SE, or Ultra/Ultra 2 about 3–4 times, or roughly twice for the power-hungry Ultra models. Charging speed is snappy, delivering a full charge to most Apple Watch models in 1.5–2 hours, while the Ultra takes a leisurely 2.5–3 hours. The magnetic suction module snaps your watch into place with satisfying precision, ensuring stable charging without any fiddly alignment nonsense.
This product is exactly what I needed for traveling and going into the office. I really liked it. The compact size and built-in cable make it super convenient and help keep my backpack organized. Although the battery capacity is a bit low, it was still very useful when I needed a quick charge. It’s easy to use and feels well-made. Overall, I would definitely recommend it — it really comes in handy when you need it most,” said one reviewer.
