My title tells you most of the story about this. It will pass some power from one car to another thru the lighter outlets, but we're talking "trickle charge" power, not "Instant starting/boost" power. If you have a good car battery but left your lights on while you went into a movie or such, this can recharge it, but will probably take 15-30 minutes (or more depending on how totally drained it is). However, if the dead car battery is bad and won't hold a charge, you don't want to wait that long, or you have other car problems (like something draining power), this won't work for you and you're better off with the old jumper cables. They say in the manual "Let it charge for 5 minutes until the green LED comes on, then disconnect it and try starting the car" followed by "If it doesn't start, let it charge another 5-10 minutes and try again", but at the under 5 amp rate I'd bet my 15-30 minutes minimum is more realistic.

Some other details if your interested, this device actually "Pumps" power where I connected it between 2 batteries and the "Good/source" battery dropped to 12.5V while the "Bad/charging" battery went up to 15V (and since I know 15V+ is "Overcharging", I pulled the plug there). Seeing the voltage go that high tells me it doesn't regulate the output power (and they even say on the box "Puts out 16-17V"), so you'd never want to use this to connect 2 batteries together and go off leaving them. I also checked the current draw and it pulled 2.7 amps while putting 1.8 amps into the other battery. My battery I tested with may not have been very drained, but still the
