Review on 🔌 AT35 USB 3.0 Tester Power Meter: Voltage, Current & USB Capacity Detector with IPS Color Display by Chris Drury

I use this meter to test various solar chargers and batteries. It is very easy to use as it starts the measurement automatically and the settings are made with just one button. It is useful to be able to switch the display output depending on the angle of the device I want to measure. The only downside to this gauge is that it's hard to see in the sun (e.g. when checking a solar charger). I have attached photos showing the difference between the exterior and interior views. Overall I think it's a quality knife and I use it regularly.
