1. As a car guy ...

I’ve been highly suspicious. However. Two friends have them and rely on them, heavily. I’ve seen one start a Toyota with a totally dead battery in -10F temperatures. After seeing that, I do think, if sized reasonably well, they’d serve their intended purpose acceptably.

3. My battery died and the tow truck guy used one of those to jump my car.

I have cables but no one in the neighborhood was home. The tow truck guy said cables were becoming obsolete because the small hand held devices were more convenient.

I found a device at Costco that is a combo air compressor and jump starter for about $100. The two truck charged $65.

I bought that battery jumper from Amazon. Works great! Small wires. You can only use it for a short time and then let it cool off.
It came with 75% charge and started the engine three times I think.
The one from Costco looked good but would get it around June 4th.
Amazon was one day.

The general rule applies: Don't buy the cheapest one or the most expensive one.
One that says it will start full size trucks is a good idea. Probably talking about $125 at the most.

I have one to help other peeps in parking lots. I have a hybrid so I can't use it on my car. My car has its on internal jump start mechanism. It too, works.

I also carry an electric jack, full array of lug sockets and 1`8" brakes bar to help people on the road. I also carry a tire patching kit for my car and other people.

I had let the charge run down to 80%. Oops.

Cables did the job.

Check everything!

Audew rated well in a comparison I did a few years ago.
