Jump Starter Power Bank

[oj88]

Unless the cells were manufactured by the same chaps who designed the Note 7's battery, there's little chance of it exploding inside the car. Just keep it out of direct sunlight and enclosed spaces (ie. glove box, center console, trunk) and just store it as low to the floor as possible, such as under the seat, to keep it relatively cool.

That said, in the last 8 years, I've only had to use my jumper cables once. I personally think that those jump-starter powerbanks are a waste of money.
