- CNN Underscored named the GT4000S its best jump starter after hands-on testing of nine models, sustaining about 3,500W for a full minute, and Project Farm ranked it number two of eight overall and its best value pick, sustaining over 1,000 cranking amps cold. It delivers 4000A peak and 800 cranking amps, starts 12L gas and 10L diesel engines, and its 100W two-way USB-C fast charge refills it in about 1.2 hours, with a five-minute charge enough for one jump. Available at capture, sold by GOOLOO, the maker's own Amazon store. Honest limits: there is no extreme-cold pre-heating (rated to about -4°F), the clamp leads are short at about 10-11 inches so the pack sits on the engine bay, the lithium pack needs a top-up charge every few months, and there is no tire inflator built in.
