Anker <b>521</b> Magnetic Battery (PowerCore 5K)
The magnets are strong, won't fall off. Nice that you can charge other devices from usb-c port too. 5/5
Didn't receive the item yet. Tracking has been showing that my package is waiting to be picked up by the carrier for already a week.
no magsafe icon while charging and only 5X instead of 15 W charging.
it offers charge-through which is great!
