Odec 20W Review – 20000mAh Power Bank

The lithium polymer batteries inside the power bank have a total capacity of 20,000mAh, or 74Wh (watt-hours).

That’s below the TSA limit, so you can bring the Odec 20W onto an airplane.

What makes it different from a lot of other portable power banks is the 20W USB C PD port that can be used to both charge the battery itself and compatible devices.

Meaning that it’s both an input and an output.

The USB C PD port can output 20W, but charges at 18W.
