GOOLOO GT4000S Jump Starter 100W Two-Way Fast-Charging Portable Car Jump Starter EVA Storage Case

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

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

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.

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.

Great... High Quality

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

only one of these little ones I would use (have returned others). friend who runs a junkyard told me about it (he uses it)
