AJMRTC USB electronic load resistor module is a simple passive discharge testing tool for standard 5V USB power supplies. It uses high-power resistors and manual switches to offer three selectable discharge currents (1A, 2A, 3A). Simply plug the USB-A connector into your power bank or USB charger, toggle the switches to pick your target load current. This dummy load is widely used to verify actual power bank capacity, perform aging tests and check the stability of USB charging adapters. Visible LED indicators show which load mode is active. The small PCB design is convenient for desktop electronic testing. Important note: The resistors will heat up during discharge. Do not touch the resistors while working and ensure proper heat dissipation.
