worse thing i ever ordered, 2nd one same result, they were refurbished Items and will not work for more than one use. BAD BUY. You can have mine for free if you wish.

This product is wonderful!

Powering 12V jump box. This single unit jump starts close to 40 12v vehicles on a single charge. Only complaint is these just dont last long. I have purchased over 20 of these jump boxes and they tend to last maybe a year on consistent daily usage for a huge auto auction. Internal parts are cheap and my main concern is these will lose a charge eventually whether is from a poor circuit board or the switch going bad.

When the time came for me to try out my DSR 116, I used it on a BMW 750 that was completely dead, it started the car with no difficulity. I had not charged it for approximately 6 weeks.

I’m not sure what thickness and warmth have to do with this unit but it’s fairly thick, and makes my jeans warm. My second DSR jump pack and I have nothing but good things to say. Epic quality, and functionality. Cable leads are quite long, which is handy. Having the 110v outlet is excellent, though I’ve only ever used it for “low draw” components (ie - jobsite radio/cell phone charger and it does great for long periods of time. Charge time for the unit seems fairly fast too, though having the dedicated charging module thing is a bit of a pain.. just another cord on the tool box.

I had bad batteries on my 2018 Freightliner Cascadia all winter long and when I would go home for the weekends my batteries would always drop down to a very low voltage. Monday mornings I would jumpstart my semi with this powerful Schumacher and without hesitation or struggle we were back in business with absolutely no issues. I would definitely recommend.
