YESPER Speed 4120 Jump Starter Review: Starts Diesel Trucks & Powers 4 Devices!

Project Farm clickbait thumbnail?? Not cool man.

Yes sir for Yesper 😂

First Aussie 😁. Ginja , a handy unit to keep in the vehicle . Great review. 😎

As a mechanic who jump started many cars and trucks over the years, too many to count, i cant believe this little box could start a car or truck...i used to haul around 40 pound jumper boxes and batteries on pull carts to get cars out of parking lots in 20 degree temps and snow and rain falling on me...they sure have come a long way

Just ordered…anyone seeing this the day of upload this exact 4120 unit is $70 with a 20% off coupon on Amazon….even with a 3 yr warranty add on it was less than $70. What happened to the finger? Looks like mine….left middle got mallet finger…takes forever!

I got the 4120 it's pretty nice for the size

There are SOOOO many brands of these jump starters. They virtually the same thing in different packaging. You can tell the cords are all the same across different brands. After a year, they are paper weights.
