How much power does it use when plugged in?

Hi Bret, I have not got mine yet but being in the automotive field for over 30 years I would say it will draw next to nothing to run that tester it should light red or green led but it would take any power to do that I will let you know when I get it for sure

Actual current used (without dismantling the unit for DMM measurement) would be no more than that of the typical mA rating of a 12 volt phone charger. Extremely low draw off the charging system. The accuracy of the display is within .1 volts, DC when compared against a Fluke 87 TMS DMM.

Brent, It uses less than a smidgin. Imagine how much a digital watch uses on that little tiny battery inside and yet lasts for years. I leave my voltage tester plugged in all the time. It's like no drain. I've had it plugged in for atleast 2 months. It's in a sailboat that uses a 5 watt solar panel to upcharge the battery. It keeps charged up mucho.

When plugged in you will see 12volts on display and when the vehicle is started the display will jump to 13-14volts max as the alternator start charging.

No idea, fully charged I can use for 5 hrs or so before plugging in, hope that helps

The plug uses 50mW with no load. That's with absolutely nothing plugged in to it. So yes it does use some power but its a miniscule amount.

.25 watts per hour according to my engineer husband, very low power, capable of running off a cell phone charger. But can really make the sound project!

I can't tell you. I returned the item. It didn't power the item I needed. Sorry

I think they say not to use it plugged in, but the charging time is a short four hours and the charge lasts for many hours, so the power it uses without being plugged in is more than sufficient to tackle the job.

It is not battery powered. It comes with a plugin transformer. Settings are retained in non-volatile memory, so if there is a power interruption, the settings remain intact.

Not sure, it won't even hold a charge when plugged in to domestic power...do not buy it!

I'm not sure exactly. But, we do not leave it plugged in...and I have never had to recharge yet when I had to use it. My wife uses it too. Basically, we love the vacuum. It's very well made and extremely powerful.

It is powered by a 110/120 volt A/C cord. No problems so far with many uses.

Does not have to be plugged in all the time. Just after using it and every 30 days. I don't know how much current it uses but you can keep it plugged in and it'll stop charging it once it's fully charged

I have no idea!!! I keep pulling it out, turning it on, using it at meetings for anywhere from 1/2 hour to 2 hours, turning it off, then doing it again. I also use it for emails in the morning. Hadn't thought about where the power comes from... Now I'm worrying. �

I guess that would depend on the processor you used, the graphics card you used, the harddrive you used and the memory and how much you had. I've never measured the power, so sorry, I can't help.

Sorry I can't answer that question. I always have it plugged in and do not rely on batteries.
