🔋 DROK DC Voltmeter Ammeter Panel: OLED Digital Multimeter with Run Time, Temperature, Power Capacity & Battery Testing - 0-33V 3A, 0-99h59min, 99W, -15℃ to 60℃ Review

After trying this product, I am left disappointed by its performance. While it might be adequate for basic tasks, this Multimeter lacked the accuracy that I required for my automotive needs. The temperature readings were particularly unreliable, making it difficult to identify potential issues. Although it is affordably priced and easy to read, this Multimeter just did not meet my accuracy expectations.

Installing this in my 3 amp power supply to replace a protruding analog volt meter. I had to make an adapter plate stub to fit the hole in the old counter. The only thing to note is that the current is measured by lifting the ground leg and connecting it to the shunt in this meter. So if you have a multi-voltage power supply with all common grounds, current may be able to bypass this meter and will not be measured if your circuit uses multiple voltages from this source. As far as I can tell…

Great product. It's a bit small but for the price I don't think it's a valid complaint. Functionally it does everything it claims to do and is fairly accurate based on two separate DMMs I tested it against. I connected this (7 in 1 multimeter version) to a 750mA charger just to give me information on what voltage and current the charger is outputting at any given time. As a bonus, it also allows me to keep track of exactly how long the charger has been on and how many Ah the charger has…
