1a/2a USB Load Resistor Tester

Regular price $1.50 $0.00 Unit price per

These USB load resistors can pair with the USB capacity measuring device that we sell. Or you can just plug this directly into a cell phone power bank and count the time it takes to discharge complete. Just $1.50 for this device and $5 for the capacity tester which we have in our accessories section.

You can flip the switch from 1 amp to 2 amp. Each of the resistors are 1 amp. When you flip the switch it activates both 1 amp resistors to draw 2 amps total. These do get pretty warm by design but if you have a small fan blow on it then it will stay cool. Without air blowing it just slowly gets warmer and warmer.
