GOOLOOGT4000S Jump Starter 100W Two-Way Fast-Charging Portable Car Jump Starter EVA Storage Case

These are great! Worth the $$$$. My second one I purchased!

Sorry I didn't take any photos but I did jump off to friends and it's still working great it's got enough juice to last for a while longer and it looks great too and it's so the case is awesome you have to get the case too

It was used on a big truck that had a dead battery. Put this thing on the battery, and it cranked right over and only pulled 3% of the life. The whole reason I purchased this thing was due to almost being stranded as a gas station and not having the best positioning for a cable jump start. The gentleman next to me had a jump pack (not this one), and I was able to get to a battery store. I decided I didn't want to be placed in that position again, so I picked this up.

Great... High Quality

I have used this charger several times since purchased. A family was stranded in a parking lot. I was able to jump their vehicle. It was also used to keep my cell phone charged up during a power outage this summer. Lasted for hours . I ended up buying 2

This product has worked well for me. I have a Dodge Ram with a 6.7 liter Cummins diesel and have used this unit to jump start it on several occasions. I have three of these units in three different vehicles. One jump pays for the unit instead of calling for a wrecker to come jump your vehicle. I am an Engineer and was somewhat skeptical of the claims that it could start a big diesel, but now I am a believer.

A bit bigger than I thought, but not an issue. Fits in spare tire well. Has helped me twice so far on the same charge. Surprisingly powerful. Leads are short, but still usable without issue.

Jumps off diesel trucks easily 12.7 Detroit best quality for money will b buying another for other tractors
