This jump pack has jumped my car in 15 degree weather a few times, plus the convenience of having an air compressor to fill up tires, alternator tester, two USB ports and a LED light all come in handy. Keep some jumper cables in your trunk as well, just in case you haven't charged your jump pack in a while/battery is super dead.
