Every number below is read straight from the test. Scroll sideways to see all measurements. Products are listed in the order they finished.
| Product | Weight | V6 dead battery start | Small block 350 V8 (partially charged battery, 3 attempts) | Big block 454 V8 turnover (weak ~7V battery, no fuel) | Diesel engine start (fully charged, 2 batteries) | LED brightness | Battery bank capacity | Bench test (cranking amps/volts/watts) | Tire inflator (15 inch tire) |
|---|---|---|---|---|---|---|---|---|---|
| 1NOCO GBX155around $370 | 5.61 lb | delivered by far the most current yet, made it look way too easy; rated the best possible score of one in this test | ready for a bigger challenge, made very easy work of the engine | over 10 seconds, most powerful jump starter in the lineup, cranked better than a fully charged car battery; rated the best possible score of one | cranked the diesel engine as if it had the power of two fully charged car batteries; one of only three jump starters able to start the diesel engine three times back to back | 154 lumens, third brightest | 65.2 peak watts, 79.1 watt hours total capacity, close second to the Gooloo's 80.43 watt hours | 1,044 amps at 10.36 volts for 10,816 watts, the highest of any brand tested | not tested |
| 2GooLoo$99 | 2.23 lb | turned over the engine the fastest yet at that point in testing; ran for 13 seconds, tied for second place (rating 1.5) with the Wolfbox | seemed even better than the Yaber Auto for cranking amps; all three back to back attempts successful | over 10 seconds of cranking time at high RPM; tied for second place (rating 1.5) with Wolfbox and Yaber Auto | performed well throughout the showdown but its safety features triggered an overcurrent fault; failed to start the diesel engine on repeated attempts | 152 lumens | 123.5 peak watts (better than advertised), 80.43 watt hours total capacity, the highest of any brand tested | 621 amps at 8.13 volts for 5,049 watts, third highest | not tested |
| 3Wolfbox$110 | 1.89 lb | lasted over 10 seconds; tied for second place (rating 1.5) with the Gooloo | just as motivated as the Gooloo; successful on all three attempts | turned the engine as well as a fully charged car battery, lasting just over 10 seconds; tied for second place (rating 1.5) with Gooloo and Yaber Auto | built-in safety design prevented it from delivering full potential; three attempts all ended with a fault code, did not start the diesel engine | too wide for the light-brightness tester, worked out to around 91 lumens | 12.12 peak watts, 66.22 watt hours total capacity, third highest | 612 amps at 9.28 volts for 5,679 watts, second highest of any brand tested | not tested |
| 4Yaber Autoaround $81 | 2.82 lb, by far the heaviest of the mid-priced brands at the point it was introduced | made the test look way too easy; ended just over 11 seconds, by far the best result up to that point | as powerful as a brand new car battery; started very easily on all three attempts | over 10 seconds, by far the best result to that point, notable for a unit that also has a built-in air compressor | performed much better than most brands and started the diesel engine three times back to back; one of only three brands to do so | light too large for the integrating-sphere tester; estimated at about 45 lumens using basic math | 167.5 peak watts, the highest of any brand tested; total capacity of 59.85 watt hours (does not place in the top three for total capacity) | 671 amps at 6.91 volts for 4,637 watts | loudest of the group at 94.8 decibels but by far the fastest, finishing in 6 minutes 37 seconds (fastest overall, about 2 minutes faster than the Dekoni) at 249 F, the coolest running pump yet |
| 5Milwaukee Hot Shot$300 (jump starter only; a compatible 18V Milwaukee battery is sold separately) | 6.9 lb for the jump starter alone; 9.25 lb including the battery, by far the heaviest unit tested | gave up really early at just over 2 seconds, a poor result for the most expensive unit tested | the super capacitor packed plenty of punch for a small block V8; successful on all three attempts | started off strong but quickly faded, lasting a total of just over 3.5 seconds | did not produce enough cranking amps to start the diesel engine | 429 lumens, the brightest light of any brand tested | not tested; the Milwaukee is a super capacitor unit and was not included in the watt-hour capacity or peak-watt sections of the transcript | 503 amps at 7.13 volts; the wattage total is not spoken in the transcript (the sentence is cut off), but 503 x 7.13 works out to approximately 3,587 watts by direct calculation from the stated amps and volts, not an invented figure | not tested |
| 6TREKURE$90 | 2.42 lb | no explicit duration is narrated for this brand in this test; the transcript only debunks its cranking-amp claim ('Definitely not 7,000 cranking amps') without stating a measured time, unlike every other brand in this section | really struggled with the completely dead battery earlier in the Ford Ranger test, but the partially charged battery helped this time; exact number of successful attempts on the 350 is not explicitly stated | performed well but not as well as the Yaber Auto, lasting around 5.5 seconds | made one successful start, described as 'one and done', did not repeat successfully | 71 lumens | 11.61 peak watts, 47.89 watt hours total capacity, second place at that point in the ranking narration | 647 amps at 7.04 volts for 4,555 watts | about the same noise as the Yesman at 87 decibels, quite a bit slower than the Yaber Auto but ran the coolest yet at 233 F; finished third overall at 8 minutes 52 seconds |
| 7YUSMAN$70 | 1.74 lb | needed an external jumper to excite it first; did the best result up to that point, though not the advertised 8,000 cranking amps | started the engine on the first, second, and third attempts, described as 'quite a bit better than the previous brands' | performed the best yet at that point, lasting just over 7 seconds | failed to start the diesel engine ('said no') | 33 lumens | 17 peak watts (best yet at that point), 27.75 watt hours total capacity, briefly the leader | 508 amps at 6.91 volts for 3,510 watts | 87.1 peak decibels, large easy to read display, hose reached 311 F (hottest of the group so far); finished in 9 minutes 33 seconds, gauge on target |
| 8Featou$100 | 2.4 lb | got too excited at the start and produced heavy smoke on the first attempt; the second attempt lasted just over 6 seconds before the unit overheated | two successful attempts, then gave up after the second attempt with an overheating error | not spinning as fast as the Gooloo but performed better than average, lasting almost 10 seconds | one of the three brands able to start the diesel engine three times in a row, despite not seeming as powerful as the Gooloo | 59 lumens | 16.26 peak watts before collapsing, 48.99 watt hours total capacity | the unit was fried and no longer working properly by this point in testing, no bench-test figures obtained | just over 91 decibels, not as fast as the Yaber Auto but ran the coolest yet at that point at 226 F; finished in 9 minutes 46 seconds, gauge fairly accurate |
| 9NACKEO$70, tied with Yesman and KoolGoo | 1.7 lb | has a boost button allowing it to work with a completely dead battery with no external excite needed; performed the best yet at that point with a 3 second run on the first attempt | seemed quite a bit better than the KoolGoo (Cold Go) and made very easy work of the engine on all three attempts | performed about the same as the Yesman (YUSMAN) both here and in the earlier Ford Ranger test, lasting just over 6 seconds | threw in the towel quickly, did not start the diesel engine | 182 lumens, second brightest of any brand tested | 9.9 peak watts, 26.49 watt hours total capacity, trailing the Yesman (YUSMAN) and KoolGoo (Cold Go) slightly | 538 amps at 7.23 volts for 3,890 watts | 88.5 decibels, the slowest air pump up to that point at 271 F, finished in 10 minutes 43 seconds, the slowest time in the whole test, but an accurate gauge |
| 10KOLTGOO$70 | 1.45 lb | needed help from an extra jumper to start; barely able to turn over the V6 engine | made pretty easy work of starting the engine in all three back to back attempts | gave up pretty quickly at just over 2 seconds | produced nothing but a couple of clicking sounds, did not start the diesel engine | 17 lumens, the dimmest of any brand tested | around 10 peak watts before shutting down, 27 watt hours total capacity, about the same as the Yesman | 459 amps at 6.47 volts for 2,970 watts; the jumper cable melted during this test | loud at 92.5 decibels but the coolest running pump up to that point at 253 F; finished in 9 minutes 44 seconds, gauge on target |
| 11DECHANIE$52 | 1.345 lb | would not work with a completely drained battery without an external excite jumper; made three attempts, struggled each time, then overheated | struggled at first but performed quite a bit better this time; three successful attempts, then overheated afterward | did better than the Sharmeal and WNDFLV but still a disappointing performance; no specific duration given | the reviewer states this brand will be retested on the diesel engine along with Sharmeal and WNDFLV since they underperformed on the previous test, but no explicit diesel-test result for this brand is narrated anywhere afterward; likely a caption/narration gap | 30 lumens | rated for 10 watts and produced right at that; 16.78 watt hours total capacity | 369 amps at 6.22 volts for 2,295 watts | about as loud as the Yesman at 87 peak decibels, very hot hose at 275 F; fastest air pump up to that point at 8 minutes 42 seconds, gauge pretty accurate; finished second overall for tire-inflator speed |
| 12WNDFLV$50, tied with Schumacher/Sharmeal | close to 1.2 lb | the dead battery was way too much for it; not enough cranking amps to spin the engine | almost started the truck on the first attempt but could not start it on the second or third before the unit overheated | way too much for this unit, same as the Sharmeal; no specific duration given | the reviewer states this brand will be retested on the diesel engine along with Sharmeal and Dekoni since they underperformed on the previous test, but no explicit diesel-test result for this brand is narrated anywhere afterward; likely a caption/narration gap | 23 lumens, second dimmest of any brand tested | around 12.5 peak watts, 19.79 watt hours total capacity | 178 amps at 7.31 volts for 1,301 watts, the lowest cranking-amp result of any brand tested | 89.2 decibels, hose reached 295 F; finished in 9 minutes 34 seconds, gauge right on target |
| 13Sharmeal$50, the least expensive true jump starter tested (tied with Winfliv/WNDFLV) | just about a pound | would not work with a completely dead battery without an external excite jumper; only lasted about a second even after being excited | performed well and started the engine on all three attempts | way too much for this unit; no specific duration given, described only as a failure | the reviewer states this brand will be retested on the diesel engine along with Winfliv and Dekoni since they underperformed on the previous test, but no explicit diesel-test result for this brand is narrated anywhere afterward; likely a caption/narration gap | 40 lumens | around 2 watts of output, completely drained after 5 hours 38 minutes at only 10.23 watt hours, the lowest capacity of any brand tested | 355 amps at 6 volts for 2,130 watts | not tested |
| 14IIXWUQ DeWalt-battery jumper cable set$18 | not tested | did not produce enough current to spin over the engine at all, a complete failure on the very first test | not tested | not tested | not tested | not tested | not tested | not tested | not tested |
How it was tested
- cold start on a completely dead V6 engine battery (single attempt, duration until engine starts or unit fails)
- 15 inch car tire inflation speed, noise level, hose heat, and gauge accuracy (brands with a built-in tire inflator only)
- small block 350 V8 start with a partially charged battery (three back to back attempts)
- big block 454 V8 crank/turnover duration with a very weak ~7 volt battery and no fuel in the tank (engine does not actually start, duration measured only)
- diesel engine start using two batteries, fully charged (three back to back attempts)
- LED work light brightness in lumens, measured with an integrating sphere
- battery bank capacity: peak watts output and total watt hours delivered as a phone/device charger
- bench test on a carbon pile tester: cranking amps, volts, and calculated watts
“The Noco came out on top with the best average finish of 1.6.”
Data notes and caveats
The transcript's captions use the string 'Noco' for two entirely different brands throughout large portions of the video: the true NOCO GBX155 (the eventual overall winner) and NACKEO/Nekio, whose result is consistently mislabeled as 'Noco' in every test after its correctly named introduction and correctly named tire-inflator mention. This was resolved by testing order (NACKEO's slot is always immediately after KoolGoo/Cold Go and before Yaber Auto, while the true Noco's slot is always after Wolfbox and before Milwaukee) and cross-checked against the closing recap math for the bench test (1,044 amps x 10.36 volts = 10,816 watts, matching the stated winning figure) and the LED brightness recap, which otherwise nonsensically credits 'Noco' with both second (182 lumens) and third (154 lumens) place for the same brand. Separately, the famous-sounding brand name 'Schumacher' (introduced as the cheapest jump starter at $50) does not appear in the description's Products Tested list at all; it is resolved to Sharmeal (the one description brand with no other match), consistent with the later nickname 'Shammy' used for the same brand throughout the rest of the video. Three brands (Sharmeal, WNDFLV/Winfliv, and DECHANIE/Dekoni) are explicitly named as about to be retested on the diesel engine ('since they did not perform well on the last test') but their actual diesel-test results are never narrated afterward; the video jumps straight to the fourth brand (Yesman/YUSMAN). This is flagged as a likely narration/caption gap rather than a silent product exclusion, and confidence is set to medium to reflect both this gap and the extensive Noco/Nekio brand-mislabeling throughout. The overall winner (NOCO) is explicitly declared by average finish score, but two additional specialized picks are also named in the closing summary without being framed as competing with the main winner: Gooloo as the best choice if diesel capability and a tire inflator are not needed, and Yaber Auto as the best choice specifically for a jump starter with a built in tire inflator; both are preserved in their own product notes rather than forcing them into runnerUp/budgetPick fields beyond the explicit runnerUp declaration for Gooloo.
