Is this good for just plugging into cig lighter so that I can keep from using up laptop battery on long trips?

It worked fine at first- about 3 months. Then it would buzz when plugged into the lighter. Then my car had some type of electrical issues that cost 2000 to fix that I say was attributed to this power adapter because after the repair my car was fine until I plugged it in again. I trashed mine, but you may have better luck and I may be giving it a bad rating in error, but I truly don't think I'm wrong.

Yes you can plug it in the cig lighter and you can use your laptop for as long as you want. Also it has 2 USB port. It's pretty bad ass

Traveled five thousand miles in a week. Girlfriend did homework on her laptop with this charger the whole time. It's all good.

Cig lighter, yes- don't know about battery connection charge though; check web offers before you buy it. I have charges for cig lighter & household electric. But why would you want a battery connection too, since one charge will last a long time, depending on usage of course.

I would make sure that the cigarette outlet is live when the motorhome is turned off. Otherwise, it should help to keep the battery charged unless you have significant power draws.

Can't address the duel battery issue, I've never tried it. As for the lighter adapter, are you serious? If you can get the cord attached without cracking a window, more power to you! ;-)

No, Not for powering a laptop. It's good for cellular phones, IPads, tablets, etc.

Yes. Just rotate the 2 metal blades in the back of the device, and plug it into a wall socket. The cigarette lighter plug is for use in the car, an you plug the wire into the top of the battery holder

No. There is a solution. I made some modifications to the output wiring by cutting the output wire short and adding a 15 amp Anderson Power Pole connector because it has much lower contact resistance. The connecting cables are 10 gauge Zip cord. The panel-to-charge-controller cable is 50 feet long (to be able to put/keep the panel in the sun) and has a less that 2% voltage drop at 2 amps, more than 16 volts into the charge controller. I made a cigarette lighter socket adapter using another A.P.P. connector. To get USB charging I use a dual port 12vdc input cigarette lighter USB charger. I also use the cig ltr adapter to power a 1 foot long white LED light bar at about 125 ma which has lasted all night (about 11 hours) on my small, light weight, 3 Amp Hour 12 vdc sealed lead acid battery. You can find the Goal Zero connectors at Radio Shack. With some 16 or 18 gauge wire you can make your cigarette lighter adapter, and/or put 3 white LEDs in series to make a nice night/emergency light. Not quite as efficient, but less expensive.

Absolutely this product is designed just for that I would refer to the Instructions (Guidelines) as far as how long to keep this device plugged In, this is what your looking for It does weigh a little bit and should be watched the first time you use It I've have been told that you might need an adapter depending on where you travel Thanks Troy

It turns off when the ignition is off but if your cig lighter is constant power then just in plug it from the cig lighter

It can be either. It comes with a cord for your cigarette lighter/power outlet and a cord with aligator clips for direct connection to a battery. Keep in mind you'll need a direct connection if you intend to use it at high power. Most power outlets are fused at around 10 amps, which at 12 volts is only 120 watts.

This inverter is to big for cig.lighter direct hook up to battery..wire that come with this inverter is a little light..you might want to get heavier gauge..

Yes, if that dvd player takes power from its cigarette lighter plug or usb (which is unlikely).Basically this device is a fancy usb adapter for car cigarette lighter with splitter for the cig. lighter.

It is designed to charge a 12 volt battery. You would need separate cigarrete lighter style charging equipment for your device

Your car has to be able to charge the battery that way so i'd check your owners manual just to be safe if you havent already. but we had a Toyota Prius and the ignition battery died so bought this and a quick jump kit. we jumped it from the cig lighter anytime the car wouldn't start. we never left it plugged in longer than to start the car. hope this helps!

Gail, the cig lighter function is for maintaining a battery on another vehicle. I doubt you could charge a battery on a vehicle you're trying to charge. I'm using mine to keep my motorcycle battery charged but I do have the charger plugged into an electrical outlet...Not into the cig lighter...Hope this helps.

I did not keep this unit but returned it. I do not think it a good idea to charge it using a cigarette lighter. It might be very dangerous. Check with professionals in this matter.
