The RELIFE XA3 Pro USB Smart Tester puts real charging diagnostics directly on your repair bench. Built for mobile repair technicians who need to confirm charging IC health, cable quality, and adapter output before touching a device, this Type-C and USB detector reads voltage, current, power, and resistance with 0.00001 resolution. It identifies PD, QC2.0, QC3.0, SCP, AP2.4A, and DCP protocols automatically, so you know instantly whether a "charging issue" complaint traces back to the phone, the cable, or the charger. A 1.77-inch TFT display and flip-screen function keep every parameter visible while you work.
