Griffin Slim 5000mAh Magnetic Power Bank

It holds a solid charge for a full day of topping up my phone, and the magnetic grip is strong enough that I don't worry about it slipping off. The 5000mAh capacity is perfect for my commute, though I wish it had a USB-C port for faster recharging.

The 5000mAh capacity is just right for a full emergency top-up on my phone without adding bulk to my pocket. I've been using it on my commute every day this week and the magnetic grip holds steady even when I'm juggling my coffee and transit pass.

The magnetic alignment snaps on perfectly every time, so I can just stick it to the back of my phone and keep scrolling without hunting for a cable. 5000mAh got me through a full day of heavy use and then some.
