With this freezing weather we are having, I have had several discussions with people on what to use to jump start their vehicle. For me, I have a NOCO GB40 for the Jeep. I have used it several times to quickly jump start a car. The only thing that I find as a nuisance is when the car battery is so low/dead that it cannot find it. This is a safety feature. It has an override button that you can use, but you have to read the manual to figure out how this feature works. I also have a bigger one for the diesel tow-rig. You can find more information at: NOCO - 1000A Lithium Jump Starter - GB40 ...
What do you use???? Always interested to knowing if there are better products we can use that might be less expensive if we ever have to replace this.
I have an older Type S jump starter. Ive used it to jump tractors in the dead of winter and a lot of vehicles with no issues. I also use it as a power bank when camping and it has a wireless charger for my phone. It's been great for me and it always outputs power when toggled so it will even jump a completly dead battery.
