    DROK® DC-DC Voltage Buck Converter Volt Regulator 5V-30V to 0.8-29V Step-down Transformer Power Module 5A Constant Adjustable LED Dual Display Amp/Volt Ampere Ammeter Voltmeter Current Volt Tester.

    Purchased this item from Amazon. Got around to firing it up this month (waiting for other components). Hooked up to 12V supply. Display reads out input voltage. Potentiometer adjustment has no effect. Hooked up resistive load. Current adjustment pot has no effect. Tried to return to Amazon Too late. Tried to contact JBtek. Links don’t work. Don’t recommend wasting your money on this one
