📲 MICTUNING Dual USB Charger Socket & Power Outlet with Digital Voltmeter - Blue LED Light 12-24V for Car Boat Marine Mobile - Efficient Charging Solution Review

After unboxing the charger I almost contacted Revain to say I received the wrong item. I wanted one with a voltage indicator and all I could see was a black area. But I thought it best to check first. Here! Blue LED indication of correct voltage, even through the seemingly opaque black cover. This replaced a faulty USB socket in my RV and fit perfectly in the original hole except the key flat orientation is 90 degrees off the original. So the voltage gauge is on the side, but that doesn't…

Installed on a jet ski today. I use a 5 amp mini fuse as the total current draw is 4.2 amps when both connectors are used. I was concerned about the parasitic drain on the amp's battery as the voltage indicator was constantly on. This decides if I need a battery disconnect switch when not in use. I also installed it and hooked it up to an aftermarket audio radio system. My numbers on the amp draw were 0.030-0.040a. Usually 0.075a is on the high side, but that's acceptable. I'm sure and this…

I bought several of these to build bluetooth speakers. The voltmeters are accurate, apparently more accurate than some of the cheap digital meter kits I've bought in the past that look roughly like the same module in this unit. The USB output makes me the most happy as it has a really good output that charges my phone quickly. I've bought many 2.1A chargers that struggle to deliver over 500mA to a power hungry device with a good cable. You have two options with this device, which is a bit…

Easy to install and works great! I use this on my VFR800 for voltage monitoring as I have a lot of electrical equipment on the bike that has been known to fry rectifiers. I also use it to charge my phone when needed. I connected it to the license plate light wire so it only comes on when the bike is on and doesn't drain the battery. It reads about 0.5 volts less than my multimeter connected directly to the battery, which I don't really care about. Yesterday I did a very long test run and…

I bought this to keep track of my voltage in my car. I have 2 amps that draw up to 400 amps max for my 4 12 and mid and high amps draw up to 100 amps. Needless to say, it's a good idea to have an idea of what voltage you're working with. Installation was very easy for me. This item is almost the exact size of a round cigarette lighter hole. For me I just had to trim the hole a bit because my cigarette hole had retaining tabs that came out easily with a razor. Uses the same wires from this to…
