As long as it stays connected to the cigarette lighter in a car, can it power devices (specifically charging laptops)?

Lighter outlet needs to be powered without key in ignition if you want it to charge without key in car. Check to see if your lighter works without you key.

Yes. It can be charged by a DC source in your car or by the AC adapter provided with the device.

Yes, it can plug into a car cigarette lighter port. As a matter of fact, it is the only connection type it comes with to power it. Also, dont buy a cheap AC to DC wall convertor. this thing draws more amps than those can handle and they will either blow or wont work.

If you have a car adapter (for the lighter plug) I would imagine it would. But the device uses constant power so using it while the car is off would probably drain your battery. But make sure the adapter you use will provide continuous power, if not you might get a lot of drops or disconnections.

I thought that it would charge up but no sadly it only works when connected to either the car's battery or into the cigarette lighter/power source.

No, it plugs into a USB port, so if you have one in your car or have a USB cigarette lighter adapter you can use it.

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

Yes, if you had a lighter adapter to usb . the charger cable is mini port (like for phone)s to USB. So you can charge it off computer or wall adapter or cigarette lighter.

No - it has a 12VDC digarette lighter output...you could get an inverter (about $20) to plug into that and power your laptop, though.

No it will not charge a laptop as laptops take 45-90 watts and it is limited to 10 watts. It can charge all cell phones, and most other portable devices. It can charge tablets but they are hard work. the power box pedal generator is a better device for tablets and you could power a laptop with it by charging and external battery first. The videos on our website show how to do this as well as under support, advanced power box guide.

If your using one 12 volt car battery out of the car it won't supply that current for any useable amont of time even if the converter was capableof doing that, which it is not. It could maintain 800 watts continuous if the battery was in the car with the car running maybe even 900 watts,but that's it. As far as the connection to the battery I'll reserve the "duh" and say: positive to post marked +, negative to post marked -.

It will yes, if all conditions/requirements are met. When charging anything inside a car you always want to be using the correct voltage type style plug/adapter & yes it will charge inside a car. Dealing with a PC/Laptop connection that would all vary, based on the USB style/type, whether that be USB 2.0 or the new style USB 3.0 which is blue port on pc/laptop/product. Some usb 2.0's will not charge this model, but all USB 3.0 will charge it that I tested it on. Hope the info helps, JoeyThePCguy@Facebook.

It is charged via usb so I don't see why not but I wouldn't drain my car battery to charge it.

Not unless you have a 12 volt power supply with a cigarette lighter receptacle.

It would appear that there is a constant power connection. My iPhone is able to charge when my car is off.

You must plug it into the cigarette lighter of your car to work and the car must have a good working fully charged battery in it. It will work with the car turned off as long as your car battery is fully charged. BUT it will in fact drain your car battery if you use it while the car is turned off for a long time. I have used it for up to 30 minutes to charge a cell phone, and I've used it for about 20 minutes to run my lap top, both times with the car turned off and I had a fairly new car battery but I would not go any longer than that and I would not use it with the car turned off if your car battery is not new or is not a high quality brand.

I would guess that it depends on the vehicle. Some leave the power to those adapters active all the time. If your device stops charging once you have shut off your vehicle then it should be fine to leave it plugged in.
