I remember when little jump packs started to become a thing a few years ago after previously having to carry around a jump pack that was the size of a car battery with jumper cables hanging from it. Those still exist, but the small hand held style are taking over and with good reason. These things are small, lightweight, and can stay charged by the car you have them in. And these little jump starters can jump current diesel engines, big blocks, and whatever you throw at them. Or so they say. Is it true? Can they do it more than once?

Project farm has tested them and here are the results.

Video Description:

Brands: NOCO BGX155, Gooloo, Yesper, Autogen, Avapow, Lokithor, Provasee, Foxpeed, BRPOM. All the jump started tested on a 5.3L and 7.4L gasoline engines with completely drained batteries. Jump starters also tested on a 5.9L diesel with completely drained batteries. Batteries bench tested for current and total watt hours. I purchased all of the jump starters to ensure an unbiased review. So, thank you for supporting the channel.
