Always watch Project Farm review videos before buying things like this. I got the GOOLOO GT4000S that he showed worked well for the price with a lot of power to crank a V8 easily, and that was one of the few that could start a totally dead battery. Most jump packs like this one won't start a car if the battery is drained below something like 8V? The GT4000S is the least expensive decent power jump pack that can work on a totally dead battery which is why I bought it last year after watching his video. I've used it to jump a V6 and a V8 without recharging it yet, and it still has 82% battery capacity left.

Just like the description says. Applies when you checkout. Doesn't seem like it will but it does.

Bait and switch going on here. The price on Amazon ends up being $20 higher than advertised here.

I have wanted one of these. This gives the kick I need to make it happen. It does look like it has been cheaper, though. This can be used across many vehicle types. I will be keeping it on the boat. No fun at all when you kill the battery with accessories, and it won't start in the middle of the lake.

Make sure the one you choose has a 45% off at checkout. As of right now, all but the orange show it.
