I spent 53 days traveling in the Yukon and Alaska this past summer (2022). Using my vans power outlet and some splitters, and some accessories I purchased off AmazonI always had my XH1 (3 batteries), G50r (2 batteries), and G100s (2 batteries) , plus three drone batteries, my iPad, a power bank, apple watches, and two iPhones charging as I drove. Never had a low or dead battery issue on any device EXCEPT for the ONE time my spouse UNPLUGGED the main cable because she wanted to power up a har straightener (LOL NOW, NOT THEN). Check out the many options available on various online retailers, as well as Staples, Best Buy etc.
