You mean you have to leave the truck running? Yeah, screw that. Just run it off the battery, ignition off. That can give low voltage problems, but if so, there's a fix for that. Get a voltage booster that plugs into your cigarette lighter socket that doubles voltage to about 24V. Now Mini is happy, especially if you use a shorter cable than what came with it. If your socket isn't live when ignition is off you can buy a DC-DC converter that wires to your battery and then does the same thing. A typical pickup battery has about 800Wh so drawing 250-300Wh is not a killer but not negligible either. You'd have to drive enough every day to top it up. And if the battery is old, or the truck hard starting, maybe too much risk. For power station relying on solar for recharging I'd pick a power station that will output PD100W to the mini and opt for 200W solar. My small Jackery doesn't do 100W, but others do. Maybe this little guy would get the job done with decent solar support: https://www.amazon.com/dp/B0FP29W3PS/
