Have not used it yet.
This really works great.
I recommend it to everyone to have in their vehicle.
Where is the device?
Tried for first time this morning and at 100 % it wouldn’t crank a 6.0 desil hopefully will do better on other vehicles nice product but it has to wk!!
This is much better than the older technology I previously had with a traditional lead acid battery weighing 3 to 4 times more.
Strong reliable starter even in below 0 degree blustery cold weather. Device recharges SUPER fast with quick charger that was included. Sleek design and easy to use. Very satisfied with my purchase.
