Building Portable LED Studio Spotlight with 20000mAh USB Battery Bank



I am tired of wasting AA batteries and I don’t want to throw out a bunch of money for a compatible low capacity battery for my portable LED spotlight that I use during filming. Today I am going to rig up a high capacity USB battery bank as the power source of my portable LED spotlight.

20AH power bank:

Velcro Cable ties:
