What customers say
★★★★★
Recording videos and taking photos kills my battery. I can keep filming while charging, and it doesn't get in the way like larger power banks.
★★★★★
Most power banks are bulky and ugly. This one feels like it belongs next to my phone.
★★★★★
I move between cafés, coworking spaces, and home all week. It's reassuring to know I always have extra battery without adding bulk to my bag.
★★★★★
You can immediately tell this isn't a cheap accessory. The materials, finish, and packaging all feel premium
★★★★★
I spend a lot of time in airports ✈️, and this has become one of the few things I never leave home without. It's slim enough to stay attached to my phone while walking through the terminal, and I never have to search for an outlet anymore
★★★★★
Gets me through a full day on campus. 🎓
★★★★★
Finally, a power bank I actually want to carry. Slim, premium, and the magnetic hold is surprisingly strong.

I've tried several magnetic power banks, and this is by far the slimmest one that still feels powerful enough for everyday use.
