Review on Eversame 2-in-1 Type C USB Tester with Color Screen LCD - Ultimate Digital Multimeter for USB C Voltage, Current, and Power Testing by Daniel Espinoza

A must for any technician or electrician! This is a great tool, especially if you work with a lot of USB hardware. I had a bad USB port or charging cable that damaged more than one device and that can damage batteries. This will definitely destroy batteries over time. This is the easiest and best way to check USB ports and cables for quality or damage. If you know how, you can easily check the charging speed and see if this charger is suitable for your device. This is far more important than most people even realize. All chargers, connectors, cables and adapters are NOT created equal and may result in damage to the battery and/or device. It has all the different readings from volts to ohms to watts that most people would never use. Here you can set the overvoltage and undervoltage thresholds. It's fairly easy to use if you know anything about electricity, and it has a basic USB tester mode for those with very limited electrical knowledge. Accuracy was excellent and I am very happy with this device. This will save me a fortune in the future and also help me test and track the capabilities of each new device.
