I'm looking to buy a portable jump-starter power bank that's rated for up to 140°F.
I'm wondering how dangerous it would be to store it in the car (trunk or globebox) if I know outside temperatures might occasionally peak at ~105°F.
(Note this is outside air temperature. I don't know how hot inside a car can get.)
I know it can result in reduced lifetimes but I do not care about that. I just don't want there to be a risk of fire, is all.
It's 14000 mAh and the thought of a lithium battery fire scares me, but I can't imagine that it wasn't designed for this use case. Would this be dangerous or safe?
Bonus points if you could describe the safety mechanism(s) that are typically employed to protect against this. It may help me understand the risks better.
