Can this draw power from my tow vehicle, possibly through the 7 way plug??? Or maybe a separate Bat.

Yes,with no problems plenty of lifting power-what a shoulder saver,now my wife can guide me back and lower the trailer onto the ball !!

I used a standard car battrery and it ran a radio 2 40 watt lamps for days before needing a charge. Make sure you dont get poitive and negitive mixed up. It killed my inverter dead.

The only way I know to charge this is to plug it into a 120 volt line. But I can tell you that it has worked when other smaller chargers would not start an engine. The other day I helped out a workman whose truck battery would not start, and the small unit he had would not turn the engine fast enough, or supply the amperage for the system. I hooked this monster up and the truck started in one second.

This unit does not have that circuitry as far as I know. The unit only allows charging to both batteries with the engine running. If your cranking battery is below the minimum charge to crank, you're S.O.L. If you install a switch to redirect the current of your aux batt to your starter then you are golden.

Probably but not if you crank it up much. This is for a steady draw from light bulbs. The only way to steadily power a car stereo is with a high amperage power supply. The easiest method is what I do in my golf cart. I have a marine deep cycle battery that runs the radio, then when I am done, I put it on charge overnight. For longer periods to keep the battery charged up I have a float charger. Yes this is a hassle but car stereos draw a lot of power at only 12-14v so they need a lot of amperage to crank them up. Easiest thing is to get a good sized (it should weigh a few pounds minimum) power supply. A battery charger alone will buzz like crazy and not be good for the constant amp draw.

That depends on whether the power is available at the cigarette lighter when the engine is off. My truck has two 12 volt power sources. One is always powered. The second one is only powered when the engine is running. You should check this first. I use a separate battery with a small cigarette lighter adapter to run my fan. It's a little heavy but it works great in my tent!

Yea you can. If it's for subs just keep in mind how much power they will be pulling. Can drain you battery is on to long while car is off. But if it's for voices you should be in the clear.

A transformer can be used if there is enough amperage.We tried ours using jumper cables from pickup battery but would only work when vehicle was running.So we bought a deep cycle battery that runs it all day with no problem.We recharge it at 2 Amps.

No way. Get a rechargable battery and use this to recharge it between uses. Max power is 5 Watts, 1/12 of what your motor wants.

No. I recommend you only hook it directly to the battery as it draws too much current to connect through the cigarette lighter and will likely blow fuses in your vehicle.

No sir, this is not that kind of a power supply. But, you Can buy battery chargers, (a type of power supply), that will start automobiles. Just search for 'Battery Chargers' in Automotive.

It would work the same as it does in the truck for asking as you had the twelve volt battery it was hooked to charge. If you let the solar panel charge your 12v bater all day you should be able to use it for laptop, cellphone charger or small fan up to maybe 12inch fan just check the watts for hay ever you plug up

Yes you can, input is 12v DC so you can go directly from cigarette lighter to the booster. Battery charge progress is displayed on the LCD screen and will tell you when to disconnect.

Sure. The power input is just a cable with cigarette lighter on the car-supply end, and medium size coaxial DC plug on at the device. You could easily cut or remove the cigarette plug and wire to a fused *12 Volt DC * power source in the vehicle

I am not sure exactly how this unit works, but if you are referring to enough power I would say yes. If you can get lighter to pull out or can access the wires behind it you can use a splice in connector.

Yes, it should be that easy. It will run on any DC supply. I'm running it directly off of my car's 12v DC through a switch. You can wire it in reverse to blow the opposite direction as well.

I never tried it that way. I just use it for a trickle charge on my wife's car if we are gone for a while. Sorry
