This a portable power bank with fast charging capability. It has 22.5W 20,000mAH USB-C in & out fast charging. There is an LED display on the front to conveniently show the battery life percentage remaining. It has two USB-A ports and one USB-C port in total and has a built in flash light.

If you've ever used a fast charger, you know how awesome they are. In just a few minutes, you can juice up your phone enough to last all day. But how does this magic work? Let's take a look at the science behind fast chargers to find out.

‍
The first thing to understand is that not all chargers are created equal. A standard charger that comes with your phone will charge it at around 5 volts and 1 amp. In terms of power, that's 5 watts. A fast charger, on the other hand, will charge your phone at around 9 volts and 2 amps. That's 18 watts of power—more than three times as much!

But why does this make a difference? To answer that, we need to understand how charging works. When you plug your phone into a charger, it starts pulling electrons from the charger and shoving them into the battery. The more electrons it can stuff in there, the faster the battery will charge.

There's a limit to how many electrons can fit into the battery at any given time. But by increasing the voltage (the force with which the electrons are pushed into the battery), you can stuff more electrons in there in a shorter period of time. That's what a fast charger does—and that's why it charges your phone so much faster than a standard charger.
