Looking for a car jump starter, 4S LiFePO₄, USB-PD is bonus

I’m looking for a Car Jump Starter.
Preferably 4S LiFePO₄ (4 × 3.2V = 12.8V) so i can also use it to recharge the car battery if it drains too low while working on the car.

Bonus would be USB-PD one or two-way (to charge the battery pack and/or to charge laptops).

Does anyone know of such a device?

There appear to be some: https://www.completebatterysource.com/lifepo4-jump-starter.php

Put [LiFePO₄ jump starter] in a search engine and go to it.
Most jump starters do not specify the battery so I assume they are some variety of 18650 Lion.

Most of them appear to be 3S though?
If you can even find it in the specs Wink

I had 4 of these

I swapped the lead acid battery from a 1.4L Ford Focus with a 12V battery made from Headway cells, then tried to start the car. Nothing. Did even hear the starter motor.
Only the windshield wipers worked.

Vipon had some nice ones a while ago; check periodically to see if any vipons come alive again.

I got a nice Baseus that way.
