I'm wondering What is the most important factor to choose one Jump Starter,Whether it is worth buying at this price.

This is spam!

The original post has a few advertising foibles but I have a similar jump pack and it starts a Lexus V6 easily with the jumper leads. The cigarette lead part is pure crapola. I bought mine for about $50 off eBay.

Was looking at an 86 AMC Eagle. Had been parked a cupple years bat. Dead not even a click. The owners frind pulled one of theas out ,don't know specs, hooked it up waited 5min and it started after a few trys , macanical fuel pump .

I always figured if I was going to spend that much I'd rather simply get a good battery.

The wires at the starter are beefier than the wires at the cigarette lighter for a reason. This isn't just spam, it's dangerous.

That thing is junk.
For $90 I can buy a real jump starter pack that actually works.

I built a supercapacitor jump pack with 400 farad caps. As long as you can get them up to 10v, you can jump most vehicles. A weak battery in parallel with the supercaps will start. I've jumped a neighbors car using it.

The real purpose was to experiment with the technology, since it isn't cheap at about $65.

Have you used one? I have and they are not junk! They are a real jump starter pack.

Yeah I have used them.
They take too long.
