And really, if you are going to use this at home all the times, then you don't need a 'battery bank' style battery booster. You can get a battery charger / booster that plugs into AC.
I prefer to use my 3rd Rolls-Royce instead of that 2nd car we all have, because it may have already left also :) And of course, we all have our car in a warm garage with a plug close by.

No idea :)

I live in van so not really concerned about temperatures falling that low!

Great deal for ~$68.

The headache of needing a boost for whatever reason and peace of mind having this thing, makes it all worth it.

The Autowit supercap booster has a second generation model which "should" arrive soon. I bought my first gen model in 2018 (?) and it works great, I've used it 3 times. I had to order it from amazon.com at the time.

Any lithium battery unit is going to be way outside its storage temperature range in your car. You are supposed to take it into the house every night. There is a hell of a lot of energy in a charged lithium battery, the fire risk is real.

I'll never jump start someone's car again, I'll just hand them the device.
Very important not to connect the negative onto the good car's negative battery but instead to any bare metal/ground. Doing that will damage battery, electronics, etc.

None of my car manuals instruct negative to metal/ground instead battery negative terminal on the good car. Where did you get this instruction?

I have been on the fence with getting one of these instead of carrying a home made 30 feet long booster cables. The thing that worries me is the capacity of these small battery packs and the thin gauge cables that comes with these units. Is the insulation material pliable at -40°C.

I've read on multiple websites to connect the positive to the bad battery, then the positive AND negative to the donor car, then the bar metal part on the bad car (not the negative terminal on the bad car), then turn on the donor car and start the bad car.

It's probably not a good idea to keep your engine running while jump-starting another car. It wouldn't do any harm with traditional electrical system designs, which is why people have done it that way for years, but you never know with modern flaky electronics. When the engine is stopped, you're pretty much guaranteed that boosting can't do any harm (as long as cable are the right way around). Every time you start your own car the starter motor draws hundreds of amps and the voltage drops temporarily way down from 12vdc. Starting another engine via jumper cables is the same thing. But when your engine is running, the alternator is trying to maintain 13+ vdc, and automatically works harder when the voltage tries to drop as you turn on more high-current circuits like the headlights. If you try to start another car with your engine running, it will draw hundreds of amps and your voltage will dip way down while your alternator is trying to maintain it, causing it to work at maximum capacity for a few seconds. That shouldn't do any harm to a properly-designed alternator and any associated electronics, and it didn't do any harm to traditional robust electrical systems. But modern fragile electronics? I guess you couldn't be sure...
