MobilePower BoostPak2

The people at QVC.com do not seem too keen on this

is this strong enough to start a very dead battery, like you left lights on? Also, wonder about the date built as that is important on batteries. I see it as more as a device charger and maybe boosting a slightly decharged battery in a small car

Jump packs I have seen to get a car going are 6 times the amps this little unit supposed to have.
