Bought the JP400 unit not long ago with this case. Haven't tried to jump anything or pump anything up, but it looks well made. But don't expect a tight fit in the case. Very sloppy.

I just bought their J1350 PRO model for $66 a few days ago which has LiFePO4 batteries and it worked flawlessly to jump start the battery on my SUV which was completely dead. Not even jumper cables had worked, but to be fair, they were pretty janky jumper cables.
Apparently LOKITHOR is the only company in the market right now that has jump starter models with LiFePO4 batteries, which seems very odd to me.
The model for the J400 seems to use LiPo batteries instead of LiFePO. LiFePO batteries would hold their charge stored in a car longer than LiPo batteries.

Too bad lifepo batteries are completely unsuitable for this application. Literally unusable in the winter.

Interesringly, lonithor knows about this and they have a model with a built in heater. This isn't it.

I have one in my car since 2018(Gooloo 800A) and I live in Northern Illinois.no issues at all. Just check it every 5-6 months. See if it got a full charge. That's all I do.

What's the best price on the best one of these? I'm fine spending more but there are so many Chinese sellers I'm not sure which one. Moderate to very cold DC area weather
