622 Magnetic Battery (MagGo)

The magnetic snap is so satisfying—it clicks right onto the back of my phone without any fumbling, and the compact size means it slips into my pocket without bulging. I’ve used it during long days out and it’s kept my battery topped up without needing to hunt for a cable.

Picked this up for my commute and the magnetic snap is surprisingly strong—my phone stays put even when I'm digging in my bag. It's compact enough to slip into a jeans pocket, so I've stopped carrying a cable around entirely.
