ROFL!
Perhaps they meant from cig lighter of another car?

I see, delivers the power through the cigarette lighter. At first I thought you meant draws power from it.

the commercial shows a woman opening her glovebox and then plugging this battery pack into her cigarette lighter which then starts her car after a bit.
I'm suprised something like this would work, given the small gauge wire that goes to your cigarette lighter. Must use something like half an amp and 12-14 volts to charge your car instead of doing a high amp, quick charge, otherwise I would think you would burn up your car.

They exist. And theoretically they work. At least, well enough to give you one or two cranks if your battery isn't really very dead.
However, it is risky at best to do this in a modern car given the number of microprocessor-controlled pieces, some of which may not tolerate current flowing in reverse very well.
Jumper cables are still the best.

Leave your cell phone plugged into the car charger then turn off and on the car several times. It will drain the battery on your cell phone (it does do it on my car, but others may have systems to stop this).
My dad is a mechanic and he doesn't see a problem with them besides the fact that they are only good for one start if the battery/charging system are truly gone.
Edit: Note: Your cell phone cannot start your car.
Edit2: Even if it is fully charged.
Edit3: Even if you bought the really long lasting battery.

Lets analyze the sentence. First, lets drop the unnecessary part from the beginning:
[*]Some device charges your car battery through your cigarette lighter.
Hmm, seems clear to me that an external device does the charging, but lets go further. The last part is also not necessary:
[*]Some device charges your car battery.
Is it clear now that it is an EXTERNAL device that charges the battery, and not the lighter that is charging the battery? Since it is clear, there is no ambiguity.

Possibly implied items:
Car battery is charged through cig lighter.
A device is used to do this.
Said device not specified as the charger. It could simply be a conduit.
Ambiguous speech FTL.
a couple different option to work with. The above link shows the dedicated powerpack that goes through the lighter.
This shows a unit that will connect two cars.
I have a unit similiar to this but only the battery unit (no compressor); it comes with dc outlet plus and gives me the option of using jumper cables for fast start, or going through the cigarette lighter. We've used it probably a dozen times with our own vehicles, stalled cars in parking lots, or for neighbors. The dc outlet is very useful for laptops when we are in remote areas with no ac at all. If you're going this route, don't scrimp on the ampreage; go at least 600 amps base.
edit: lol this thread moved so fast that my reference to the "above link" is not looking at the link i was referencing.

It is poorly worded, but it isn't ambiguous. I think the problem stems from you extending a lesser used definition of "through" to mean more than it does. Your first implied item does not say what item is charging the battery via the cig lighter. "Through" does not correctly mean the cig lighter is doing the work.

i saw the commercial
i would guess it is a pack of Lithium Ion batteries with an adapter cord for the lighter plug
you are basically putting another battery in parallel with your car battery to give it a boost
if you battery is just barely dead, this should work and be safe
but if your car battery is really dead, i could see an issue with too much current going through the lighter adapter wiring
jumper cables are cheaper
