Power is Supplied by the Device Voltage(7.5v-20v) being read then I assume?

Yes, In a previous review I noted the drain of then meter alone over a period of burn in time. Very very negligible. Nice meter, can't go wrong.

That's normal it is reading the alt ouput of the the vehicle when it is running. when the vehicle is not running it should be a steady voltage reading.

Power isn't as big a problem as the voltage drop. By the end of the strip, you may only be getting 10v, for example. You should measure it.

there is a voltage converter you simply plug in. That part of the is wired.

what are you measuring? Are you measuring batteries? If so, then it's pretty normal to have a higher reading except the 3.7V one.

I can't specifically answer the question but written on the adaptor is: Output: 5V--2.0A Max

it is powered through the USB cable ,, most devices have powered USB ports it's rare these days to find non powered USB ports

This is what it reads on the adapter's label:INPUT: 100-240VAC50/60Hz 0.4A MaxOUTPUT: 5.0v =-= 2000mA

the device itself only uses 12V at 2A ... my original power cord blew a fuse during a brownout so i don't have it anymore, i got a 120-240V at 2A replacement to power the device & it works just fine

Honestly I'm not sure, I have never checked the voltage... That would probably be a question for the manufacturer.

It may not be reading wrong. Batteries usually put out a little more than they are rated.I know my car battery usually puts out about 13.5V

I don't believe so. It is powered by the PSU and simply checks the voltage of each connector to make sure that they are within specification.

Only if the thing you are plugging into it, had Dual 110/220 V, usually listed on the device or power supply label, This is not a converter from 220V to 110V.

Output voltage is 24 VDC, connector diameter is 5mm external, didn't measure internal. Center positive.

The small details on the back simply show AP-10-12V. Not sure what that means but I'd be on the safe side and use a power adapter. Don't wanna burn out this baby

Is the red led power-on indicator lit?If so,your problem is most likely with the device.A volt-meter would help.

It's possible that the battery is bad, that would be the first thing to check. If not the battery then check the power supply.
