Diesel jump start guaranteed.
Old school guaranteed to work. Simple charge the battery pack up and use it to jump Start a diesel transit cab. Leave it connected to mains supply so it's ready to use when needed. Couldn't be simpler.

Could do with a stronger case but still powerful
Heavy but simple to use. Case is a bit lightweight though. I put it the rear footwell and it rocked a bit onto the seat and the case cracked. No problem starting a 7.4 ltr v8 hi compression petrol engine.

Started my car no problem
I bought this booster starter for my husband as he is going through a bad spell with his health and our car is not getting used for weeks upon end and the battery keeps going flat, four times this has got us out of the 💩with our car battery going flat and although we’re in a breakdown service it’d take time for them to come out get us started so it’s been an absolute must have for us, anyway I placed my order and had to contact the seller with regards to the packaging and they were very helpful, as it was a gift I needed the packaging to be disguised, the seller was courteous and friendly and when my order arrived it was packed very well indeed with no hint of its contents, I can’t fault the seller or the booster starter either, many thanks indeed 🙏
