In this video, Iβm building a simple USB load tester using only old, wasted components from my electronics junk box.
A USB load is super useful when you need to:
test USB chargers π
check powerbanks β‘
diagnose bad or unstable USB cables π
Unfortunately, my old USB load tester died while testing a damaged charger⦠so instead of waiting two weeks for a replacement from AliExpress, I decided to build one myself using what I already had.

π§° Whatβs inside this DIY USB load:
βοΈ How it works:
With a single switch, I can test devices in two load modes:
No microcontrollers, no displays, no fans β
just pure old-school resistor load.
π Typical DIY problems included:
Sometimes it really is easier to buy a ready-made tester β but thatβs not the point.
This project is about reuse, improvisation, and DIY spirit.
β οΈ Important note:
This is a basic and unprotected load.
If you need accuracy or safety β buy a proper USB load tester.
