Battery Booster Pack instead of Solar?

[FareEnuff]

Does anyone have thoughts or experience using a battery-booster as back-up power instead of using or to supplement solar (good or bad)?

We are planning to do a little of-the-grid camping, 1 or 2 nights at a time (boondocking or non-power sites) while travelling. In the past our battery has been good for short stints and we've recharged while driving the truck however I'm looking for a power back-up for the battery that's simple and reliable (regardless of weather). I am thinking we can connect the booster to the battery to maintain a full charge and we can recharge the booster through the truck's inverter or at a full hook-up site. I also like a booster v solar as they can come with portable compressor which is always handy and if I have an issue with my truck battery I have a booster to get started.

I started researching battery boosters as an alternative to solar panels and I've landed on MotoMaster Eliminator 1400A Booster Pack features:
- 1400 peak amps and 700 crank assist amps
- Built in 120 PSI air compressor with digital display and programmable PSI
- Three 3.1A USB ports
- Digital LCD screen with easy to read icons provides internal battery voltage and PSI readout
- Built-in high efficiency charger allows the unit to recharge faster and can be left connected without risk of overcharging
- Premium internal battery featuring AGM technology

Appreciate any input
