As someone who's constantly on the move, my Apple Watch often dies before I do. This little keychain charger has been a game-changer. The first thing I noticed was how perfectly it snaps onto my Series 7 - that satisfying magnetic click tells me it's charging without fumbling with cables.
During my last business trip, I got three full charges out of it before needing to recharge the power bank itself. It's not lightning-fast, but when my watch was at 10% during a layover, 30 minutes of charging while grabbing coffee gave me enough juice to last through my next flight.
The frosted texture feels premium in hand, and the color-changing LED ring is genius - I can glance at it in my pocket to know if I need to top up the charger itself. Pro tip: That red light means 'charge me soon' when you're packing for a day out.
Is the magnet as strong as Apple's original? No. But here's how I make it work: When charging on-the-go, I actually keep both devices in my jacket pocket together - the fabric creates enough friction to prevent sliding. At my desk, I just lay them screen-down on my notebook.
The included Type-C cable charges both devices simultaneously - a feature I didn't know I needed until I could charge my dying watch while juicing up the power bank during my morning routine.
After two months of daily use (including being tossed around in my gym bag), it still looks and works like new. For travelers or busy professionals who live by their Apple Watch notifications, this $30 gadget pays for itself in convenience.
