What's the point of using LiFePO4 for portable power banks?

Longevity and safety. It's not advisable, but if you leave this one charging in a hot car under the sun, it's much less likely to catch fire than a regular Li-ion power bank.

23w max so not like it fast charges like others do. And they are quite large for the capacity.
But it carries CCC cert, and I like to think that's the only reason one would buy it.

They do look the same, although the ASIN and UPC codes are different.

Is it viable to keep one of these as a backup power bank in a cold car?
