III Conclusion


From a brand with some of the world's best-selling power banks, the ZMI LevPower M10 Power Bank (WPB100) continues the high standard of the Xiaomi-funded ecosystem brand with top-level components, neat layout, and an in-house buck-boost controller IC. The inclusion of a Lightning input port is a nice touch, especially for iPhone users.

At $36, it is also very reasonably priced for a premium power bank that checks all the boxes. But it is not available in the North America yet.


Pros:

18W PD fast charging input and output with 10W wireless charging.

Nice design and finish with top-level components.

Extra Lightning input port.


Cons:

A little on the thick side.
