I have this one- https://www.amazon.com/gp/product/B015TKSSB8/ref=ppx_yo_dt_b_search_...

It has am amazing amount of boost power, started my stone-dead ISX Cummins at 30 degrees and still had 3 out of 4 charge indicator lights left. I don't know how long it will hold a charge, the longest time it has sat between uses was about 8 months and it still started what I needed started-but I didin't notice what the remaining charge level was.

I bought it based on someone's recommendation on here, I have not been disappointed.
