No capacity rating? Can it do more than 2 jumps from fully charged?

said to do 20 starts. but also says 30W input 60min charge to full. Do you believe 30Wh can jump start a car for more than 1 time?

You are way off here. The most famous one that most people recommend is the Noco GB40 and that one is capable of multiple starts as can be seen on youtube vds. The Noco GB40 only have a 24WH size battery (smaller than Lokithor model here if your claim that it has 30WH capacity is true)

Haven't seen a LiFePO4 jump starter before. These should be much more reliable if left in the car long term, right?

Yes, better than lithium ion. They still recommend discharging to 50% and fully charging every 3 months.

My obligatory statement of spend the extra $60 and get a jump starter that will work every time, even when user error or other products fail... Super Cap jump starters are around $100 on sale, they are worth the money over anything like this with a battery. Only time it has failed to work for me, is when I was helping a stranger with their car that had one of those DUI blow testers. Their wasnt enough power to get that activated long enough for it to pass the test and allow it to turn over the engine, so that was not the jump starters fault.

Not likely, temperature shifts will probably destroy the batteries way before their actual life span were to end. All battery based jump starters come to Chicago to die after not even 2 years of summer heat waves and deep freeze winters. Unless you live some place temperature stable or you keep your car park indoor every time, these packs will fail. I have been through well over 6+ packs with normal batteries which all failed. Then I switched to super cap and I dont have to worry about charging it or storing it in bad temperatures. My super cap has now lasted me over 5 years and going, and its used a few times each year usually to help others.

Here's a counter-opinion. I have 6 Lokithor battery jump starters with tire inflator (models JA300 and JA400) that I've kept in 6 different family vehicles over the last two years (outdoors through super-hot summers and fairly cold winters) and have had to use each of them multiple times. They have worked both as jump starters and tire inflators every time. I recharge them after every use and set reminders to check them periodically for charge level. Yes it's nice that the Super Cap jump starters don't need to be checked for charge or "topped off" periodically. But it's also easy enough to set a recurring reminder on your phone to make sure the battery jump starters are fully charged, and then it's nice to not have to wait 5 minutes for capacitors to charge up before trying to start the vehicle, and it's nice to be able to turn over an old engine long enough for it to actually start, and it's nice to be able to jump a vehicle with a completely dead battery. Any of my 6 Lokithor battery jump starters would have started that DUI tester car just fine, so yes it was the super cap jump starter's fault since it cannot sustain amperage long enough.

Sure there are pros to the super cap type jump starters and they obviously meet some people's needs better. But they are not objectively and categorically better than battery models.
