There is a 1A/2A current button to switch 1A or 2A current discharging.
Work voltage is 5V, power is 10W-20W, switching the button to change resistance and current.
Pay attention to the high temperature generated in the work process of load resistance, please don't touch to avoid scald and stay away from flammable items.
Working with indicator light, switch button marked current value, to indicate the current mode at present. Steady light means reaching up to standard output rating, off or flash means the power supply is less than rated output standard.
Adopting real 5Ohm winding resistance to make sure the testing results more accurate.
Module Feature: Power: 10W-20W Resistance: 5 Ohm -2.5 Ohm Swithcable Work Voltage: 5V Work Current: 1A/2A Note: Because there is large current passing through the winding resistance, when the load tester is working, it will generate very high temperature. Please do not touch the winding resistance during the usage or just finishing the usage, to avoid scald. And please keep the load tester away from combustible items. Perhaps there will be little strange smell in the first use when resistance heating, and it will disappear after few times use. This is normal phenomenon. Please don't worry about this. Package Include: 2pcs 1A/2A Load Tester
