1A / 2A USB Tester - Dummy Load Resistance
The device is used to check the actual efficiency of the USB port, e.g. chargers, power banks. To do this, connect the resistor through a special USB meter (not included) and turn on the selected load range - 1A or 2A.
When the device is under load, the resistance caused by high current generates very high temperatures. When using the device, be extremely careful not to touch the resistive components.
