Favorite jump box

NOCO Boost X GBX75 2500A is what I run, I use the NOCO battery charger too. Good products.

GooLoo GP4000. I watched the Project Farm video and this was in the top 3. NOCO was number 1. For the price of the NOCO I was able to buy 2.

I have one of these. It's ridiculously expensive at around $800, but if your vehicle won't start with it - it's not going to. I've personally started a stone cold dead 12.5l diesel with it and it spun the motor over better than it did with fresh batteries alone.. They've got 2 other models that are much less powerful, and much less expensive (though still pricey) that would certainly start any Jeep.

Seems like this thread title should be part of a yo-mama joke?

What is everyone's recommendations on a jump box to keep in the jeep? I was looking at this one. Since jumper cables are old school this seems to be the way to go.

bought that exact model 5 years ago, and I've probably used it 7-8 times
3 times when I stupidly drained my own battery... rest on a friend's boat

In my profession as a carhauler, I've used many different kinds of jumpstarters to start many a dead vehicle in frigid conditions.

I've had a couple of the little jumpstarters sold at Costo for 50-60 bucks, and seen/used other similar ones. They often have the same little adapter that adds jumpstarting capability to the battery pack, so I expect these will all perform about the same. If the battery you're jumping is just low, these will usually give you enough boost to start it. But you don't get more than a couple attempts before they've gotta be recharged. They are nice and small and I could keep one in a jacket pocket while climbing up the carhauler to start a car.

However, these little cheap units are just NOT capable of starting a car when there's so little voltage that the lights and computers don't come on. They need some amount of existing voltage there before they even try to work.

Having used other options (includinig snap-on), the best have always been the NOCOs, and I finally got a GBX75. This is great for starting anything including 7L diesels. I've even used it to boost the 13L in my Peterbilt, though I wouldn't do that too frequently. It's overkill for Jeep-sized motors, though, even 392 - I'd say the GBX45 would be great.

Be sure to get the NOCO gb X series, as these are the only ones that charge with USB-C Power Delivery instead of a unique barrel charger. You can charge and discharge them with USB-C like you use for anything else.

I have the NOCO GB40. Never had to use it for one of my vehicles, but I've used it a few times to help family members and neighbors. Works great. Last time I used it, one of my neighbors got home from a long vacation and both of his cars needed to be jumped. One of them was completely dead. The other tried to start but wouldn't get there. The GB40 was sitting in my garage for months since I charged it. It started both vehicles and still had a good amount of battery left. They go on sale on Amazon pretty often.

I also have the Genius2D on my generator battery to keep it charged. And the GEN5X1 on my boat to keep that charged. No problems with any of them.
