Product features: Real-time monitoring of charging status charging equipment, for the detection of charging equipment such as chargers and mobile power supplies, display voltage, current, power and other data on one screen to diverse testing needs. High-definition screen is obvious AT35 adopts 0.96-inch IPS high-definition color LCD screen, 160-degree wide viewing , high brightness, long working life. One-screen display of various data Real-time monitoring of voltage/current/power/internal resistance/temperature, etc. of USB electrical equipment when working, one-screen display, real-time grasp, more and 5-digit resolution measurement is more. Product measurement resolution is increased to 5 digits, higher precision and more measurement. Widely compatible with fast charge recognition - key off-screen display flip.
