Here are some specifications of the power module:

l 5000 mAh;
l Overcurrent protection;
l Short-circuit protection;
l Transfer efficiency: ≥90%;
l working temperature: -20℃~+55℃;
l Wireless

The best part of the power module I think is it's wireless. You don't need to a USB cable to connect the phone and power. You know, sometimes, using a USB cable can be inconvenient and the USB cable is easy to be defective if you use it a lot.

Besides, safety is important, so overcurrent protection and short-circuit protection are good for me. And working temperature can fit most extreme environment needs.

Portable power bank on Amazon is about $50, so what's the price of power module?
Guess it and the winner will get one module for free. Winner will be announced on Jan.15
