New technology and super fast recharge
The difference is in the shorter charging times and the powerful jump start delivering the same power on every start This will more than start my Ford Ranger on a Cold winter day and can be used as a power bank in between I’ve have a jump starter in each of my vehicles and have had many over the years and this one has by far a better capacity and specification Please I spent the money on this one

Awesome little package
Fantastic portable jump starter, got this little unit on special and it doesn’t disappoint, got handy features like a torch if you goofs jump starter of a night time, ports so you can charge your device. Ip65 water and dust resistant, 5 minute quick charge feature. Can’t go wrong grabbing one of these handy for your vehicle or if you see someone who needs a jump start. 👍

Piece of mind
I purchased the Boost Lithium charger 1750A to predominantly start my ride-on, it does this with ease time after time and I still have not had to recharge it, I have now also used it to start a car with a flat battery when shopping - so far I can not fault it, top quality, easy to use, compact and always ready to go. I am very happy I purchased it.
