Most powerful jump starter and only diesel-cranking powerhouse

NOCO GBX155 Jump Starter (No Inflator)

Average Finish: 1.6

Purchased for: $370

Made In: China

Search on Amazon

Premium NOCO GBX155 jump starter rated at 4,250 cranking amps and weighing about 5.61 lb. No inflator, but an extremely strong pure jump starter. Boost mode allowed it to dominate every cranking test: it spun the dead V6 and 454 better than a fully charged car battery and easily handled everything Project Farm threw at it. Light output is about 154 lm, battery bank capacity a strong 79.1 Wh, and it delivered an enormous ~10,816 W on the bench test (1,044 A at 10.36 V). One of only three units that could start the diesel three times in a row, and clearly the strongest of the bunch.

NOCO’s GBX155 topped nearly every test: longest and strongest cranking, top-tier bench-test watts, excellent battery capacity, and flawless diesel performance—at a premium price.

Gooloo Jump Starter (No Inflator)

Average Finish: 2.5

Purchased for: $99

Made In: China

Search on Amazon

High-end lithium jump starter (no tire inflator) rated at 4,000 cranking amps, 24,000 mAh, 400-lumen light, and fast 100 W USB-C in/out. Weighs about 2.23 lb. With boost mode it was the fastest cranker yet on the V6 (~13 seconds), handled the small-block 350 and the 454 for over 10 seconds of strong cranking, and has excellent battery bank performance. Light output ~152 lm, top battery capacity at 80.43 Wh, and ~5,049 W in the bench test. Safety circuitry prevented it from fully feeding the diesel, but it finished second overall on Project Farm’s scorecard.

The Gooloo nearly matches NOCO’s real-world cranking while adding huge battery-bank capacity and 100 W USB-C I/O at around $100.

YaberAuto Jump Starter with Air Compressor

Purchased for: $81

Made In: China

Search on Amazon

Heaviest combo unit at ~2.82 lb, rated for 8,000 cranking amps, 160 PSI, 65 W charging, up to 160 W DC output, and 600-lumen light. Has a boost button and absolutely dominated the dead V6 test with over 11 seconds of cranking. On the small-block 350 it behaved like a fresh car battery on all three attempts and powered the 454 for over 10 seconds. Tire inflator was by far the fastest: 6:37 (397 s) at ~94.8 dB and ~249°F. Light output ~45 lm, battery bank capacity 59.85 Wh, and about 4,637 W in the bench test. One of only three units to start the diesel three times back-to-back.

YaberAuto blows away other inflator combos in tire-fill speed, cranking performance, and diesel capability—making it the standout choice if you want a built-in compressor.

Project Farm’s final scorecard average finish across all tests (cranking, diesel performance, tire inflator, battery bank capacity, and bench-test power).

Time to inflate a 15-inch car tire from flat to target pressure. YaberAuto’s compressor was dramatically faster than the rest (lower is better).

Peak sound levels recorded at each built-in compressor during the 15-inch tire inflation test (higher values indicate louder operation).

Measured watt-hours each unit delivered while powering a DC load until shutdown. Gooloo led this test, followed closely by NOCO, with Wolfbox and YaberAuto also performing very well.

Watts delivered under a heavy carbon-pile load (amps × volts). NOCO’s GBX155 was in a league of its own, with Wolfbox and Gooloo rounding out the top three.

Number of successful back-to-back starts on a Dodge Ram 2500 diesel with one real battery and one wooden dummy battery. Only YaberAuto, Featou, and NOCO achieved three successful starts; NOCO did so with the strongest cranking performance.
