Review on MakerHawk USB Load Tester - Intelligent Discharge Resistor Module for Battery Capacity Testing, Adjustable Constant Current, 150W 200V 20A by Jacob Fish

Features multiple connectors for testing various standard PSUs as well as screw terminals. Reading was clear except some things were written in Chinese. The load adjustment knob to set the current was a little touchy and difficult to set to a specific current. The fan only worked when the tested voltage was loaded. The cooling fins were easily bent and the fan blades were exposed, so care must be taken to protect these parts. Every chance helps. Universal burden.
