USB Electronic Load Aging Resistance Charger 3A/2A/1A Discharge Charging Bank Mobile Power Test with Adjustable Switch

  • .


According to Ohm's law (voltage/resistance value = output current), the USB discharge load is designed to load different power resistance values ​​through the two switches above, and 3 types of current aging can be obtained, which are 1A/2A/3A. Onboard Corresponding indicator lights and power indicator lights with different resistances are clear. It is easy to use and can be used for aging test of power bank mobile power charger.

1. 5V USB test
2. Three gears can be selected
3. The indicator shows the status
4. Hardware introduction and description
5. Board size: 67*22mm
6. Weight: 14g

Instructions for use:
1. After power on, the power indicator D1 will light up.
2. The USB plug is plugged into the 5V output interface. Because of the resistance value and the maximum power limit of the resistance, it cannot be connected to the fast charging interface above 5V.
3. Switch S1 to the "ON" gear, D2 lights up, the 4R7 resistor starts to work, and the current is about 1A.
4. Switch S2 to the "ON" gear, D3 lights up, the 2R5 resistor starts to work, and the current is about 2A.
5. When S1 and S2 are set to the "ON" gear at the same time, the two resistors work, and the current is about 3A.
Because a large amount of current is consumed by the working heat of the resistor, the resistor will get hot. Take special care not to touch the resistor with your hands to avoid burns.
Package included:
1 x Power Test Module
