Cheapest LFP portable jumper shot up to $90 (Vtoman).

Okay deal to get you through the year, hopefully LFPs drop by then.

Looks like USB C is input only and both outputs are USB A (with one being 3.0 quick charge).

LFP or LiFePO4, is lithium iron phosphate.

A different, newer type of lithium battery. It can handle extreme heat better, and keeping them fully charged does not age as significantly.

Also, they are safer because they don't bloat. No spicy pillow in your car.

Yes, Get the traditional one. The Milwaukee one works only if you have a Milwaukee battery with you. That alone seems like a pretty bad idea. Traditional super capacity you just need a good 12v source or a power bank to recharge and use it.

P9QNU5LH still seems to work. If you're using the Amazon app you might be missing the step of tapping on the arrow that appears in the promo code box to apply the code (before tapping the Continue button).
