Instead of taking the plant with you I would buy an automatic watering device. They are inexpensive. The one I use can be set for how often it waters and how much. One can do the job but for extra security I always use at least two in case one dies the other keeps providing enough water to keep the plant alive until I get home.
Just buy an inverter🤷🏿 We used one to run a tube tv and an xbox back in like 2007 running off the cigarette lighter on an 8 hr road trip😂 then u can plug whatever light u want in
