MagGo Power Bank (10K, 35W, für Apple Watch)

The little screen showing battery percentage is such a nice touch—no more guessing if I’ve got enough juice for my watch and phone on a long day. It’s compact enough to slip in my jeans pocket, and the built-in Apple Watch charger means one less cable to forget.

The 35W output charges my phone noticeably faster than my old brick, and the fold-out stand for the Apple Watch is surprisingly sturdy. I've used it on two trips now and the battery gauge on the side takes away all the guesswork about when to top it up.

This thing charges my phone and Apple Watch at the same time without any fuss, and the 35W output actually keeps up while I'm using it. The built-in screen display is a nice touch, showing me exactly how much juice is left so there are no surprises.
