- Spec: Item Type: USB Load Tester Material: Printed Circuit Board Working Voltage: DC 5V (USB power supply) Function: A USB discharge load tester designed according to Ohm's law (voltage/resistance value = output current), through the two switches above to control load different power resistance values, and obtain 3 kinds of currents, respectively 1A, 2A and 3A. Onboard corresponding different resistance indicator lights and power indicator lights are very clear. Simple to use, you can test the power bank and mobile power charger. Applicable Scenarios: For electronic equipment, power bank, mobile power, charger. Package List: 2 x USB Load Tester How To Use: 1. The USB plug is plugged into the 5V output interface. Because of the resistance value and the maximum power limit of the resistor, it cannot be connected to the quick charging interface above 5V; 2. After power on, the power indicator D1 will light up; 3. Switch S1 to the "ON" gear, D2 lights up, 4R7 resistance starts to work, the current is about 1A; 4. S2 is turned to "ON" gear, D3 lights up, 2R5 resistance starts to work, the current is about 2A; 5. If S1 and S2 are switched to the "ON" gear at the same time, the two resistors work and the current is about 3A. Note: 1. Do not use the product in a electrostatic environment, otherwise static electricity will damage the electronic components; 2. The USB plug is plugged into the 5V output interface. Because of the resistance value and the maximum power limit of the resistor, it cannot be connected to the fast charging interface above 5V.
