Stuffcool's 10000mAh Mega 40 power bank is a pint-sized powerhouse

This 10000mAh power bank has dual USB-C ports and goes up to 40W.

(Image credit: Apoorva Bhardwaj / Android Central)Each USB-C port is able to go up to 20W total over the USB PD protocol (12V/1.67A), and in my testing, I found that it went up to 18W on the Pixel 9 Pro XL.
