It is a USB Load Tester Discharge Resistance, Steady Red LED lighting indicates that the rated output power reaches the standard,The Red LED Not bright or flashing indicates that the power supply less than the rated output standards.Feature:
- The load tester has the 1A/2A switch allowing you to choose 1A or 2A current discharge
- Tin is used in the back of this board to ensure better radiating
- It adopts winding resistance of 5V to ensure more accurate testing result
- The USB load gauge can do discharge test and aging measurement directly on USB power supply or USB output port of mobile power supply
- LED status indicators:
- Steady Red LED lighting indicates that the rated output power reaches the standard,
- The Red LED Not bright or flashing indicates that the power supply less than the rated output standards.
- When the load tester is operating, it will cause high temperature because a huge amount of current flow through the winding resistor. Please don't touch the winding resistor during the usage process or when you just finish your usage.
- Due to winding resistor's particular features, there might be a little smoke or strange smell after you power up the USB load tester for a certain time in your first usage. This is normal phenomenon and will disappear finally. Supporting the use of ASIN:B00JYAJJ5E or B00K7YUFI6 or B00JW78YIW.
