Use this 1A/2A USB Constant Load Resistor together with the USB Digital Capacity Meter to measure the claimed capacity of any power bank
Switch to 1A load if the power bank to be tested cannot deliver 2A current output
Green LED light means 1A load (5 Watts) and red LED means 2A load (10 Watts)
1A/2A USB Constant Load Resistor
5V / 1A; 5V / 2A
1A Mode (5W)
Slow Discharge (Green LED)
2A Mode (10W)
Fast Discharge (Red LED)
What's in the Box?
1A/2A Constant Load Resistor
Switch to 2A mode to test if the power bank can really deliver the fast charging 2 ampere current output
Switch to 2A load for faster testing completion time if the power bank being tested can deliver 2A current output
Be careful not to touch this load resistor when the testing is on-going. It becomes extremely hot during the testing period. The energy being drained by this load resister is being converted from electric into heat energy!
