Being a profressional with a full-time job requires rock-solid power stability (along with other things). This makes living out of one’s car difficult, but not impossible.
My initial tests of streaming from parks have all suffered from lack of power. I knew I would going into it, but wanted to see just how far the built in batteries on everything would take me. Turns out, not far, so I bought a Jackery 300 Plus with 100w solar panels for 600 dollars. Most people living from their vehicles get at least the 1000 but I can keep it in the hourse for family if I need something bigger later. This should be able to power everything I need to work for a few days at least including all the streaming gear recharging.
