Do these things work in -15F weather?
6000a 12liter diesel is pretty funny.
Yeah I'm not sure where they get these claims.
The $370 Noco claims 4250a PF tested 7032watts /12volts is 586a
$55 Hompow claims 6000a PF tested 5299 watts /12volts is 441a
The ones I purchased at Costco will barely start a single cylinder ATV, they got recycled. I'm hoping this one is better.
As we know, lithium batteries do not perform well when very cold. I'd expect this one is no different. Might have to use body heat to warm it up in such cold weather.
In the project Farm videos he tests them after leaving them in the freezer.
It's similar to a car battery is this regard. Bigger battery has more CCA. Which decreases when cold.
The Battery certainly has less capacity when cold so the larger it is to start with the better.
The noco gbx155 does have a bit more capacity but it's also six times more expensive.
This jumper was one of the largest capacity jumper that is a reasonable price.
If the jump starter was left untouched in a trunk for a year and then you tried to use it and it was -15f outside that might be a toss-up.
But if you brought it outside from your warm house and then tried to use it at -15 it would start no problem
In a few of the older project Farm videos, when he tested them and they were very cold... They got progressively stronger up until like the 4th or 5th attempt (must have warmed up the internals with each attempts)
