Function: USB discharge load tester designed in accordance with Ohms principle (voltage/resistor value = output current) controls the different power resistance values of the load through the two switches above to get 1A, 2A, and 3 types of current respectively. 3A The corresponding on-board different resistance indicator lights and power indicator lights are very clear. Easy to use, can test power bank and mobile charger.
Applicable scenarios: electronics, power banks, mobile power, chargers
How to use:
1. The USB plug is plugged into the 5V output interface. Due to resistor resistance and maximum power limit, it cannot connect to a fast charging interface over 5V.
2.Power indicator D1 will light up when you turn it on.
3. Switch S1 to "ON" gear, D2 lights up, 4R7 resistance starts working, current is about 1A.
4. S2 switches to "ON" gear, D3 lights up, 2R5 resistance starts working. The current is about 2A.
5. If S1 and S2 are switched to "ON" gear at the same time, the two resistors will work and the current is about 3A.
Package List:
2 x USB Load Tester
Note:
1. Do not use the product in static environment. Static electricity can damage electronic components.
2. USB plug has 5V output interface
