12V battery jump box recomendations?

only comment i will make if you live somewhere hot or don't use it much, don't charge it over 80%, the batteries don't like sitting at 100% for long periods of time without cycling, and most of these jump units, can jump multiple times before being dead

I have the Clore ES3000 and the ES6000, that I bought in 2006. The ES6000 was for my Dodge Cummins, which I sold. The ES3000 is in my Silverado.

One time years ago I had a dead short in my Dodge in the winter. Both batteries completely dead. The ES6000 started it easily.

My Noco drops off considerably after that battery indicator drops off one bar. Having the tool work is more valuable to me than preserving the optimal lifespan out of it.

The robust integrated captive leads and good clamps are great features.
I have the similar GB155.

Any of them with detachable leads would be an immediate no go for me. I know I’d end up loosing the leads plus it’s got to loose amperage at the connection.

These boxes have more use than just a jump box. On my GooLoo, the plug and socket seem well-made. I would not want the large alligator clips from dangling while the power is on and not connected to a battery. The clips are also well-made with plastic jackets to minimize them accidentally hitting each other.

If you never use your box as a power supply or source of light, then permanently-attached jumper cables make more sense.

My Noco leads attach securely to the side of the box so they aren’t swinging around arcing out. Plus even if they did hit each other nothing is going to happen because they aren’t live until the box detects power from a battery. I’ve used the box occasionally to charge my phone but I don’t make a habit of doing that and I have better flashlights.

It is amazing how small and capable the newer jump boxes have become. Some use lithium-ion batteries and some use large capacitors.

I have never had the larger boxes that have attached jumper cables on the sides. Earlier models like that were large, heavy, and used lead-acid batteries. All of the makers mentioned in this thread offer smaller units with detachable cables, and much larger units with fixed cables.

The NOCO Boost-X GBX155 unit rated #1 in the Project Farms head-to-head durability review.
4250A, great for jumping big diesel engines too.

I was surprised at the tests they did.
Worth while to watch and draw your conclusions if 2nd, 3rd or 4th place contenders would meet your needs.

I’ve started a completely dead 5.9 Cummins with the biggest 4250 Noco. Not only did it start it cranked over like the properly charged starting batteries do. I have the smaller 2000 amp Noco. I borrowed a machine with a 4bt Cummins that had a draw and killed the battery. I started it several times with the 2000 amp Noco.

it shouldn't, one bar should be 75%, i routinely run around there with mine, but its not a noco

I almost just made a jumper from scratch. I would have used a high CCA battery, then simply wired in 2 or 0-gauge jumper cables & stored it plugged into a smart charger. Weight wouldn't bother me, I'd have to have it in a substantial box with handle.
The battery was weak on my Deere 3038 so I went back to Wal-Mart getting an Everstart group 51R battery for $79. Only 1 year warranty but it started it fine.
