Review on ⚡️ Mini Digital DC Voltmeter: Waterproof, Dustproof, Drop Resistant Tester - 3 Colours (Red, Green, Yellow) by Michael Moulton

Everything worked fine, most were blocked with my DMM, two were clipped at 0.03V. The DMM, which is a current clamp meter in the mA range and is much more accurate than whatever I have, gave me 00A. I double checked the spec and its resolution is 1mA so that should have worked. If I find time I'll check with a third DMM so I can give you a good average power consumption. The power consumption is so important to me and maybe few of you because I connect it to a battery with a small solar panel that has to run for a long time and only 10mA is a lot in my situation.
