UGREEN MagFlow 10000mAh Qi2 25W Wireless Power Bank Built-in Cable

Why it's worth it

A Qi2-certified magnetic bank that clicks onto the back of an iPhone and charges at 25 watts wirelessly, which is faster than the usual magnetic pack. A built-in USB-C cable adds up to 30 watts of wired power and doubles as a carry strap.

Magnetic banks usually make you choose between convenience and speed. Android Central puts most MagSafe-style packs at 7.5 to 15 watts wireless, well behind what a cable can do. This one is Qi2 certified at 25 watts — UGREEN says that gets an iPhone 17 Pro Max to half in around 38 minutes, against roughly 54 minutes at 15 watts. It's still not cable-fast, but the gap is much smaller.

The magnets are the unsung part. There are 17 of them, and owners describe the snap as firm enough that the phone stays put while they're walking or holding it up to watch something. A magnetic pack that slides out of alignment charges slowly and heats up, so grip is a performance feature, not a convenience one.

What to know

• –Fit and speed depend on your phone
