    • Frozen Semi Tractor Starter..
The size appears small in the picture, but it’s pretty big and beefy. Just what i needed to jump start my semi truck, that’s been parked for months through the winter.

    • Very powerful.
Expensive, but well worth it and will start any diesel engine. That’s completely dead. And do a multiple times without recharging. Hoping that it will last a long time. Will do an update in a year to see how it holds up.

I bough this cuz I boost cars all the time and I want something secure and reliable cuz I’m on the move all the time and let me tell you this , a 300 dollar booster would do better job then this thing first of all you have to wait 60 seconds to just use it and then once you able to use it the power that it gives it like a cheap booster there’s no way this thing would work or some big trucks with a totally dead battery , I tried it on two different cars with a fully charged booster and barely start the cars and then on the third try I try to start a dead battery on a 2002 vw Passat and guess what , it couldn’t even start the car at all like a 1000 dollars device with so many features couldn’t even start 3 cars with one charging then this thing it’s useless and I mean useless bro don’t even waste your money with this thing get a 300 dollars booster from auto zone it’s gonna work way better then this thing plus it’s really pricey I mean the only explanation I have for this issue it’s that I got q bad unit so I contact customer service and they can return my money but they cannot replace my unit so how would I know if I just got a bad unit or if this thing it’s really cheap ... show more

    • Excellent Jump Pack! Crappy buckles

I own a diesel repair shop, and do everything from diesel pickups, semis, tractors, etc. I didn't figure I would use this a lot, but ever since I bought it, I find myself finding a use for it all the time! Very convenient! I have jump started 4 (8-12L) Semis that were completely dead, and cranked for 30 seconds or more each, on 1/2 a charge with this before. My only gripe is the case. Which is beautifully constructed, save for the pull tabs on the zippers, and the buckles. Absolute garbage, they broke in about a week of mild use. So, I replaced the pull tabs, as shown. And installed some field repair buckles to replace the cracked originals, as shown. I don't know why they would cut corners there, when everything else is a beautiful package. But, it's fixed now, you can find both of those products on Amazon as well for cheap. Also, be advised. This comes with the quick charge cable, you do not need to buy it separately! ... show more
