I have the yellow 900 amp jump pack and the purple 1900 amp one too, use them to run glue guns and led lights for paintless dent repair work.
I have used them on trips a couple of times as a back up, but the are only have the equivalent of 19amp/hr and 38 amp/hr respectively internal batteries, so are a bit limited for all but a night, maybe 2 nights.
Trouble is charging them, the ciggy charger or little 240v supplied charger takes 7 or 8 hrs minimum (I use a Supercheap 6amp mains charger at home, about half an hour to charge, but not practical for use 4wdn etc.
I would either get an arkpak type setup, the in built smart charge is pretty good with the 12v 6 amp charger.
But really a thumper, plain battery box, or just second battery fitted is probably best for you, charged from isolator via main alternator charging, set and forget.
A 100 amp/hr battery is probably ample for your needs described, only needs minimal driving each day, or set up a 120amp solar panel during the day to top off.
