We're still talking about camping, right? I see that things have changed. My first time was one canvas groundsheet, one thin blanket, one two-person tent, one solid fuel itty-bitty stove. Froze through a sleepless night, ate grass in the attempt at breakfast, no place to poop and a forced long hike to get back to a toilet. Probably the most desperate I've ever been to make a pong. Boarding school builds character through torture.
Swore I'd never "camp"again. GF talked me into a family outing. Air mattress that sagged heavily to my side because I weigh more than her, sweltered through a sleepless, humid Midwestern night. Never again.
I do not recognize this activity that you describe, with generators and batteries.
