Checked the specs on the LG website, and while it's actually 27" not 24", it's still only 1080p60. Digging deeper it turns out you cannot remove the batteries, which might be a problem both for air travel and adding more battery life than 3 hours. There's no aerial connection, so using Freeview is out of the question without an external STB, only one HDMI, no onboard media storage, SD card slot or USB port. Meanwhile for less than half the price, you can get a 32" smart TV designed for caravans and boats that runs off 12V DC. Comes with built in DVD, Freeview, satellite tuner and all the usual apps, assuming you can get internet where you are.
On that point, I've also been camping with friends where one chap had the same idea as me and took a small projector and portable screen to keep the kiddies amused at night, but was still relying on a mobile data connection to get any content. Didn't work as he expected, so next time I offered to bring a small DVD player and box of discs. There's the key thing to be said for physical media, they work offline.
