Number 7. ZMI PowerPack Wireless 20K Pro

The ZMI PowerPack Wireless 20K Pro is a capacity-first option for people who want fewer recharges and more time between outlets. I put it in this list because 20K-class power banks are great when you’re traveling or charging multiple devices.

Pros

+High capacity for extended use
+Great for travel and multi-device charging

Cons

-Not as slim as smaller magnetic packs
