On Project Farm's carbon-pile bench test (Nov 2025), boxes claiming 7,000 to 8,000 amps held roughly 500 to 670 amps, while NOCO's 4,250 A GBX155 held 1,044 A at 10.36 V. Eight units, ranked by the amps they actually held at the clamps. #8 Milwaukee M18 HOTSHOT (503 A) · #7 YUSMAN F04 (508 A) · #6 NACKEO Star03 (538 A) · #5 WOLFBOX MegaVolt24 (612 A at 9.28 V) · #4 GOOLOO GT4000S (621 A, most stored energy) · #3 TREKURE TK20 (647 A) · #2 YaberAuto YA90 (671 A, started the diesel 3 of 3) · #1 NOCO Boost X GBX155 (1,044 A). Before you buy: pick a unit with a boost / force-start button for a fully dead battery, top it up every 2-3 months, and keep it out of a hot dashboard. Bench numbers are from one test session; listings and box claims change, so check the model and price the day you buy. 📚 SOURCES Project Farm: "Don't Buy A Jump Starter Until You Watch This Review!"
