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. WARNING! 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. Specification: - Dimensions: 85 x 18 x 16mm - 1A / 2A load switch - Material: metal, plastic - LED indicator (1A - green light; 2A - red light) - Resistance 5ohm (tested) https://elecena.pl/product/22604506/1a-2a-usb-tester-dummy-load-resistance 2023-02-22 https://elecena.pl/product/22604506/1a-2a-usb-tester-dummy-load-resistance 2025-10-29
