After leaving my lights on for like an hour today and the car not starting, I figured I should get one of these.

I'll wait to see if I can get one with an air compressor that I'll probably never need first though.

These are awesome to have when your car won't start because of a battery issue.

Is "Bookoo" a spinoff of Gooloo which is a spinoff of a reputable brand?🤣
I own the Gooloo GT4000S and it is awesome. Project Farm reviewed it as the best performing jump pack at a reasonable price which is why I bought it. I also bought it because it is one of the few models that can jump a TOTALLY DEAD battery whereas most jump packs can only jump a somewhat low battery. Trust me when I say you really want to save yourself a lot of aggravation and get a jump pack that can jump a battery in ANY state, not just a somewhat low battery.

So I received this yesterday. I had a car with a dead battery, like so dead you'd need a second person to rev the car with the live battery to use jumper cables and revive the dead battery (which I didn't have). Used this which was 75% charged and my car started within a minute. Good deal, would recommend

I was going to order one tonight as well. I needed one a couple of days ago, and this is the second time in the last 2 years.


Sale ends in like 6 hours, but I think I burned the code already.

I've had that issue before when I put a code in, but don't checkout and the code doesn't work the next time.

Any hints?
