The ZMI LevPower M10 Power Bank (WPB100) is an all-in-one power bank that’s tailored for Apple users with 18W PD bi-directional fast charging, 10W wireless charging, and a convient Lightning input port. It is also MFi certified and Qi certified. Here’s our teardown review.

I Design

The power bank has an anodized aluminum alloy casing with a matte finish in grey. The wireless charging area is made of plastic anti-slip rubber coating. Our unit is a bundle version which comes with a braided USB-A to Lightning cable (we prefer a USB-C to Lightning cable which can fast charge iPhone 8 or later).

II Teardown

Pry open the top cover.

Remove the bottom and the screws.

Push out internal components from the bottom.

Separate the aluminum alloy metal casing from the internal components.

Below the wireless charging coil is a thermal paste that dissipates heat from the coil. A thermistor is fixed on the surface with high temperature tape.

On the other side is a lithium polymer battery.

The battery cell is from ATL (one of the world’s largest battery manufacturers),4.35V,10000mAh,37Wh.

Now we separate the wireless charging part from the power bank part.

First let’s take a look at the wireless charging part which consists of a single coil and a slim PCB board.

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.


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

Nice design and finish with top-level components.

Extra Lightning input port.


A little on the thick side.
