An absolute lifesaver that is simple and easy to use

SPLA5HFebruary 8, 2026✓ Verified purchase

I purchased the 1000A 37Wh version of this Hulkman portable Jump Starter and it has been a lifesaver on a couple of occasions in the cold winter including one instance when my wife needed a jump start at 7:00 in the morning to get to work. This thing holds a charge for many months and it is easy to use. The instructions are easy to follow and it takes minutes to get a car jumped and running. We decided to purchase this based on the digital percentage display that lets the user see how much charge the Hulkman has. I'm surprised so many other jump starters don't have this obviously useful feature. I should also note that my wife keeps one of these in her trunk at all times and simply charges it a couple of times a year to make sure it is topped off. A woman stranded on the side of the road can be putting her personal safety at risk when soliciting the help of strangers, so this gives my wife peace of mind for any battery issues. Overall, I'm glad we have this item. Read more

A must have for your car!

This is the second one I've bought. This was a gift for a cousin of mine and he loves it! It comes in handy and for the price you can't beat it. Very easy to use and holds charge really well. It's very practical and do yourself a favor, get rid of the jumper cables and buy this! You won't regret it! Read more

Yes, but one

RayRockDecember 12, 2025✓ Verified purchase

The starter gets five stars. I’ve taken a star off for two reasons. First, the instructions could be more clear. There are both a USB and USC inlet but nothing explains their purpose or capabilities. Second, it comes with a double ended USC charging cord but no cube to plug it into a wall outlet. What I ended up purchasing is a USC cube for my car’s 12v (cigarette) outlet which allows me to recharge the jumper immediately after use. Otherwise, it works perfectly and I’d buy it again if I needed another. Read more

Couldn’t crank over a 1.9L TDI.......

Sean B.January 13, 2026✓ Verified purchase

Tried this on a 99 vw 4 cylinder 1.9L tdi diesel. First time using the brand new hulkman, had a 76% charge right out of the box. Hooked it up and it said ready, went to start car and it did nothing! Was really surprised and bummed out as it was advertised to start a 3.0L diesel. Will be returning, its a little heavy just for using as a flashlight ...... Ill add that i got a new battery and car is starting normally now, nothing else wrong with the car. Read more
