The NOCO Boost GB20 is a compact lithium jump starter rated at 500 amps peak, enough for engines up to 4.0L gas, with up to 20 starts per charge. Its UltraSafe clamps are spark-proof and reverse-polarity protected, so a wrong connection does not damage the unit or the vehicle. It doubles as a USB power bank, recharges in about 3 hours, and adds a 100-lumen LED with 7 modes. At 2.4 lb and IP65-rated, it fits a glove box and shrugs off water, dust and knocks. It is the smallest Boost model, so it suits small cars, motorcycles, ATVs and mowers rather than large trucks or diesel engines, which need the bigger GB40 and up.

Owners of motorcycles, mowers and small cars rate the GB20 highly for starting engines reliably after long storage and for the safe clamps. Complaints center on its limits for bigger engines and the short cables.
