okay, couldn't find a thread so i'm starting one

I fly drones for a living, I love to do it and it's the one thing I want to keep pursuing.

recently I got tired of dealing with people and I want to get my self a small tent and just get myself into a local forest or big open area where i am able to "wild camp".

i want to film and take photos tho, so I want to take my filming equipment with me

i have everything packed up and settled, except for one details I'm trying to go around.

how do i get electricity to charge my stuff? solar panels are a no-go in the UK. I thought about buying a generator but I can't find one small enough to take with me.

I don't have any vehicle so transporting stuff will be on my bagpack only... any sugestions?
