How much current does this draw? I.E. can I leave it plugged in for 2-3days..

This question got me curious so I checked itwith a digital multimeter. It only draws 8.3 milliamps (0.0083 amps) when the engine is not running. This is only 0.2 amp hours per 24 hour day, a tiny amount, so I would not hesitate to leave it plugged in. Note: Some lighter sockets turn off when the engine is off (except when accessary switch is turned on) so that would also shut down the meter. Hope this helps.

I don't think you should leave it plugged in. I charge it for an hour before a planned use but when I simply grabbed it and ran, it had enough juice to start an 8 cylinder jeep.

Sure you can. But you will not need to keep it plugged in. It should do the job without a recharge.

It should be plugged into a 20 amp outlet.You can plug it into a 15 amp outlet but nothing else on the circuit should plugged in, even then you are still pushing over the limits. I bet most people do this though. Not good.

You should not have to charge it that long.There must be a proablem with it.2 hrs worked with mine.Try another plug otherwise send it back

You can leave it hooked up and charging while runnning the 12v DC fridge.Depending on how many amps of draw your fridge uses it may or may not go over the amount you are producing with the panel.Do you know how much amps that the fridge draws?Thank you,AW

you can leave it plugged in as long as you like. the light changes color when it is finished charging. will need new usb cord though. it may also break if you are trying to recharge a high amp device. my GF uses it every other day, it gets pretty hot when charging her phone.

I don't know, I never leave mine plugged up, I put it away. It heats up in seconds, no need to leave it plugged. No other solution.

It does draw a lil current as long as you have 12v and about 3.2amps of current ur good i have it on a 5 amp fuse and it has never blown. It does use about 32 watts. now this is just what i have clamped it useing at run not fire up. Hope that helped

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.

That is entirely up to you. I leave it plugged in on long trips to monitor performance, bit take it out when we get home. It is used mostly as a code reader for my son's truck.

Yes, no problem. Recommended so you don't run out. I keep it plugged in when using.

Not sure of the "current draw" but it must plug into a 110V outlet. Probably not much draw as it only works a circuit board and small fan.

It doesn't draw power. It has an internal battery which is charged with a USB cable and supposedly lasts 6 hours between charges. Haven't had mine long and haven't used it enough to know if it really lasts a full 6 hours.

I don't think it draws that much, but why keep it on when not in use? Just plug it in to check then disconnect, I think would be best.

I have tried it both ways, but it always seemed that when I left it unplugged and needed it, there was no power. Now I leave it plugged in all the time. However, probably like other devices of this nature, it might be a good idea to let it run out occasionally and recharge.

I have charged 2 devices at a time with no issues. It can run about 5-6 full charges on devices before you need to plug it in again.
