The NOCO Boost HD GB70 is a 2,000-amp lithium jump starter for cars, trucks, boats and RVs with gas engines up to 8 liters and diesel engines up to 6 liters. It claims up to 40 jump starts per charge and adds a 400-lumen LED light with 7 modes, USB charging for phones and tablets, and a 12V output for tire inflators and inverters. Its spark-proof clamps and reverse polarity protection make it forgiving for people who have never jumped a car. Against smaller Boost models it trades portability for much higher engine capacity; against cheaper lead-acid boosters it is lighter and needs no regular recharging, though it is bulkier than pocket-sized jump packs.
