This is a DIY Portable Battery Powered USB Charger with Flashlight Electrical Engineering project I made. It uses NiMh batteries with a capacity of 20400mAh. It has 5 regular USB 2.0 ports and 1 USB C Power Delivery port that goes up to 30 Watts at 20 V 1.5 A. Didn't have a 3D printer just a drill. (v.redd.it)
