Does this provide regulated 12v, so it will drop it down when the car is running and at 14v, and step it up when you are starting the car?

This device depending of the model will, with an input of 12 volts step down to 9, 6, 4.5 0r 3 volts. It will not on the other hand with a lesser input step up the voltage to a higher level. It is not an inverter, it is a converter. With an input of 14 volts it will give the step down voltages name above at about 5% higher momentarily, until the alternator output taper down to 13.5 volts or so. The tension from the ouput of the alternator, and the input tension of whatever device is power is different by about 1/2 volts. This because of the loss in the line and the size of the line.

I would have no idea what does, since I do not have a volt meter hooked to it, the battery will drop to 10 volts any more means you need a new battery.

If you find the right 12V connection in the car, one that energises when the ignition is on say, just use that for the 12V input to the monitor

it will provide power until its source of 12 volt power dies, i have run mine all day day in day out for a year in harsh environment it powers my laptop, big printer, internet and phone chargers, air compressor at times, (run a direct connection with fuse to your battery for best results), use caution as it will warn you of low car battery but it keeps running and will kill it (my truck has 2 batteries). it is a great inverter, no problems

Hello I believe it is a voltage regulator only,I bought several of these and I did not see any thing more then just to regulate the voltage, and it works good,make sure the voltage regulator and the solar panel are both 12 or 24 volt as i burned my first 12 V reg as I bought and hooked up a 24 V solar panel and cooked it :(John graber

It does not. It has a shut off for an overvolt condition and provides some noise filtering, but it does not regulate voltage. The manufacturer's specifications confirm this.

It should be able to jump start any 12-volt vehicle. Make sure to keep it charged when not being used.

It probably will. Most cars will turn off the power to 12v socket when car is turned off. In that case there is no problem.

I believe the statement is referring to the starter battery of your vehicle. You would not want to risk running your starter battery "dead" or too low, as you will no longer be able to start your vehicle -- this is not good, as you will be stranded at worst, or inconvenienced. If the car is running (as in a tripp down the road), it is fine to plug it in and use it while the engine is running. If you stop for 15 minutes or so, it should be fine, as long as your battery is in good working order. Most newer vehicles have a ignition powered 12 VDC socket, and will turn off when the vehicle is "off". This is not guaranteed, so use your best judgement and consult your owner's manual for details.

yes from 0.001v (1 milivolt) to 0.200v (200mv) than it drops down to 0.20 up to 2v

It doesn't really matter what voltage your vehicle uses. All this does is bridge the starter trigger wire to a constant positive. Once you hook it up right it will work.

It needs to also be tapped into a 12v source. Mine is installed behind my stereo.

IIRC it does, the jump starting option draws a lot of power. I'll check mine when I'm in the garage and if it's different I'll let you know.

Oh you mean 12v for the car. No it doesn't. I just got an adapter from Radio Shack and I can charge on the go...

This part was made for a car it only works in a car. I would not use it for anything but 12 volts. There is no schematic to tell you where the wires go. It was I think used for the heater speeds for the motor in a car. If you can figure it out it supposed to be four speeds. I could not get it to work so it sits in by junk pile of old parts.

no, but it works great as it was designed to do. nice clean 5 volt step down

It has to be wired to a 12v source. I ran mines to a terminal on my ignition so it comes on when the key is on.

It has a wiring harness that you tie in to a 12v. Supply under dash or wherever. Works good.
