Car and Driver's best overall: just two buttons, 24-inch cables and enough power for almost any consumer vehicle. It's pricier than most, and some Amazon owners find it overpriced or report battery issues.

If that catch is a deal-breaker

Highly ranked portable jump starters whose biggest complaint is something else.

#1 in portable jump startersGOOLOO GT4000S Jump Starter

CNN's best jump starter overall. It had some of the strongest output in CNN's tests, plus a big screen and instructions printed on the back. It's chunky, has no hard case, and its 4,000-amp rating is marketing; CNN measured about 3,500 W.

Its catch: bulky#3 in portable jump startersTOPDON JumpSurge 3000 (JS3000)

CNN's pick if you need several jumps per charge: it has 88 Wh, and CNN's load tests drained it more slowly than the Gooloo or NOCO. Its output was similar to the Gooloo's, despite an inflated 3,000-amp claim. It costs more than CNN's picks, and Amazon owners are split on charging and durability.

Its catch: mixed reports on charging and durability#4 in portable jump startersNOCO Boost Plus GB40 (1000A)

The best-known jump starter and the smallest one CNN and Car and Driver tested. It's CNN's budget pick and Car and Driver's most compact pick. Its small battery (24-30 Wh) may give only one or two jumps per charge, the leads are short, and some owners say it couldn't start a truck or stopped taking a charge.

Its catch: small battery, few jumps per charge
