This is a 4000 amp rated jump starter pack, which is going to be able to actually jump start a lot of your diesel trucks. So, basically it's up to a 10 L diesel engine or a 12 L gas engine. And that's actually kind of a big deal because a lot of your diesel trucks, obviously you've got two batteries that you got to deal with. It takes quite a bit of juice to get these trucks going.Watch B

Used it twice for other people’s cars, started straight away and what a fantastic compact jump pack it is. I have now just purchased a second one for my sons car. Being compact it fits away nicely and the person who used it twice is now considering buying one too. I’d definitely recommend.Read N
Yes, both devices deliver as advertised but if you’re looking for the best jump starter of the two the GT4000S is it.Read
