the heaviest unit tested

the lightest unit tested

by far the heaviest unit tested

needed the boost button to override activation on the completely dead battery, then doing by far the best of all units so far

rated at 2,500 peak amps but performs just as well as the Yesper YJS 40

jump starter mode would not activate on the completely drained battery and there is no boost button or override; presenter used a separate battery charger to trick the unit into activating, and once activated it only lasted two and a half seconds before powering down and sounding its alarm

boost button works properly, delivers more than enough cranking amps to start a small block V8

has a boost button, like the Yesper, that has to be used to activate the jump starter on a completely drained battery; spinning over very quickly with more than enough cranking amps to start the engine

claims 4,120 peak amps and is doing the best so far at this point in the video, plenty of cranking amps even for an engine that might take a while to fire up

spinning the engine over even faster than the Foxpeed, plenty of cranking amps to start the engine

makes more than enough power to spin the small block eight cylinder pretty fast for about 10 seconds, more than enough cranking amps to start the engine

at 100 percent charge, plenty of cranking amps to start the engine

spinning the engine over a little faster than the BRPOM, plenty of juice to last 10 seconds and more than enough power to start the engine, down to 93 percent charge afterward

at 7.5 V, equals 6,720 W, the highest wattage of all units tested, about 1,200 W better than the second place finisher

at 7.2 V, equals 5,566 W, the best result of all units tested up to that point

claims 6,000 peak amps but came up way short at 649 amps at 7.4 V, equals 4,803 W

at 6.6 V, equals 4,475 W, took third place from the Autogen at that point

at 6.4 V, equals 4,422 W, moved into third place at that point

at 6.8 V, equals 3,502 W, enough to take the lead from the Povasee at that point

at 6 V, equals 3,348 W, about 150 W better than the BRPOM at that point

ran out of steam at 517 amps at 6 V, just over 3,100 W

rated at 3,000 peak amps, ran out of steam at 510 amps at 5.8 V, equals 2,958 W, pretty low compared to most of the other brands

at 6.2 V, equals 2,722 W, almost 400 W less than the BRPOM, the lowest bench wattage of all units tested

delivers more than twice as many cranking amps compared to some of the other brands, presenter says it is ready for a much bigger challenge than this test vehicle

made very easy work of the truck on all three attempts, presenter says it is ready for an even bigger challenge than this 454

would not activate using the boost button; presenter had to use another jump starter to activate the unit, and with that help it made very easy work of starting the truck

performed well on the bench test at almost 4,500 W, delivered more than enough cranking amps to start the truck three times back to back

performed very well on the bench test at over 4,400 W, made very easy work of firing up the truck on all three attempts

made very easy work of jump starting the truck on all three back to back attempts, presenter notes not bad for a $90 jump starter

did better than the Foxpeed on the bench test at over 3,300 W, made very easy work of starting the truck on the first attempt and did well on two more attempts

did not have any luck on the first two attempts and struck out after three attempts total, did not start the truck

made very easy work of jump starting the truck on the first attempt, but it is one and done, could not repeat the start on further attempts

claims 2,500 peak amps and delivered just enough cranking amps to get the truck going

spinning over the engine the fastest of all the brands tested

only lasted 1.5 seconds before powering down from being too cold, did not start the engine

only lasted 1.3 seconds before powering down, did not start the engine

performed very well, more than enough cold cranking amps

performed very well without any issues

spinning over the engine a lot faster than the Povasee at this point

spinning over the engine a little faster than the Foxpeed at this point

started the engine after the 30 minute warm up period

performed good enough to start the engine but did not spin it over nearly as fast as the less expensive Yesper YJS 40

performed well and lasted long enough to start the engine

delivered 78.4 W hours, second place behind the Yesper Armor Pro 2

hours, about 23 percent less than advertised

hours, about 47 percent less than advertised

claims a 99.1 W hour capacity but came up 30 percent short at 69.2 W hours

hours, performed about the same as the standard Yesper YJS 40

claims 88.8 W hours, came up 20 percent short at 71 W hours

claims 88 W hours, struggled on this test at 44.1 W hours, about half the advertised capacity

claims 23,800 mA hours, around 88.1 W hours, came up 47 percent short at only 46.1 W hours

claims a 299.5 W hour capacity, came up 26 percent short at 220.5 W hours, still the highest actual capacity of any unit tested

claims to make 77.7 W, came up 42 percent short of its rating at 44.9 W hours
