321 MagGo Battery (PowerCore Magnetic 5K)

I was skeptical about a 5K magnetic battery being worth it, but it’s slim enough to stay on without bending my pocket, and it topped my phone up from 20% to full during a long commute. The click-on grip is reassuringly firm, no wiggling mid-charge.

It’s genuinely pocketable in a way I didn’t expect, and the 5K capacity has been enough to top off my phone twice during a long day out. The magnetic alignment on the back is spot-on, so I never have to fiddle to get it charging.

The magnetic snap is so satisfying, and the 5K capacity got me through a full day of heavy phone use and even topped up my earbuds. It charges up pretty fast overnight, and the slim build fits perfectly in my jacket pocket without feeling bulky.
