Review on Thlevel Charger Voltmeter Waterproof Motorcycle by Darrin Parasson

I like the product. It looks very nice and is very accurate to a certain extent. By this I mean that when my phone is plugged in, the voltage reading on the display drops 0.5 volts, but the power supply is correct. For example, I have a repair station with a regulated DC output that is accurate, and I checked this with the workstation's voltmeter. This was correct but when I plug my phone into USB the display shows a drop from 0.4 to 0.5 but the workstation stays where it was set. I also tested it on a jump box and it was the same. When I turn off the phone, it returns to the correct voltage reading. I will be using this on my trolling motor, I use it with AGM batteries and never run it below 12.4v so it's like my throttle gauge and it's important that it's accurate. This applies as long as the phone is not connected to the network. I can deal with it very easily.
