We really need to standardize portable battery specs in Watt hours (Wh).
This battery pack description is a rollercoaster of confusing specs for the average person:
"15,000 mAh" (@3.2V) = true, but most would assume the same voltage as other chargers, so at ~3.2V LiPO4, you'll get ~15% less power than a ~3.7V Li-ion at 15,000 mAh, so this seemingly inflates the specs
"8,000 mAh" (@5.0V) = true, but hardly anyone measures at 5V, so this seemingly deflates the specs
"48 Wh" = ultimately, the correct way to compare power between battery packs
The tl;dr is that if you can't find Wh on a Li-ion battery pack you're comparing this to, think of it as a "~13,000 mAh" (@ ~3.7V) pack.
Pro: $18 isn't bad for something that will give you a 1-2 boosts on your phone and watch for an extended day.
Con: 1.1lbs is a touch heavy when you consider the ~$95 (sale price) Anker A1695 is 1.5lbs for ~2x (95Wh) the power.
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.
Is it viable to keep one of these as a backup power bank in a cold car?
Far better than a traditional Li-ion. It'll still wear, but probably age at about 20% of a traditional power bank.
For some reason they haven't merged the two threads about this... but I have this model in every glovebox. And my cars endure both snow and 120 degree summers.

They are the best power banks for storing in cars that endure very hot or cold temps.
Normal power banks last a year in my climate. These I expect will last 3-4... Long enough for sodium banks to hit the market.

Yep, shouldn't be an issue. LiFePo4 works in much higher / lower temps compared to Lithium. Just dont leave it in a spot where it'll get hit with direct sunlight in the summer.
It's only 23w though so you can only charge phones and other small electronics with it.

The power is accurate, but your pro/con omits two huge pros:
1) LFPs last way longer. This could last 5-10x longer. Especially when you factor in power banks are used to zero much more often, which LFP benefits from.
2) Hot and cold. As noted above, this will last in a car for years probably.
You would not buy this for a backpack or purse. This is for a car or a tiny solar setup.
