Digitale Voltmeter DC 100V 10A Voltmeter Ampèremeter Blauw + Rood LED Amp Dual Digitale Voltmeter Gauge Elektromobiel Motor Auto

Totally ingenious, small, can be used individually. I forgot some pictures at work, I'll add them later. The operating voltage can be supplied from the measuring voltage or an external supply.

I received the package very quickly, about two weeks, it works perfectly, it shows the voltage, amperage, and also measures the W power.

It shows the current in error. During the measurement it shows a decrease in voltage, but in reality it did not decrease...

Accurate enough for my measurement purposes. Easy to read and easy to integrate.
