Relife XA1 Current And Voltage USB Tester

The Relife XA1 Current And Voltage USB Tester is a small meter that sits between a USB power source and the device being powered, and shows the voltage and current flowing through the connection. It is a quick way to check whether a charger, cable or power bank is working properly, and a handy tool on phone repair and electronics benches.
