Anyone found reliable 12v Raspberry Pi power options for boat use?
We day sail on our J/24 boat and don't have a permanent battery on board. I bought an EcoFLow River 2 which is 256Wh, weights ~4kg and has nice ergonomics to carry around (I charge it at home). It gives my 12V DC (connected from cigarette lighter) to power RPi, RPi 7in monitor, WiFi router, 7 port powered USB hub (AIS dongle, GPS, IMU, etc). I put a small fuse box just in case in between EcoFLow and my devices. Also, it gives me "instrument panel" (tiny LCD display) where I can see power consumption.
Edit: Answering your initial question - I use 12V powered USB hub which converts 12V-5V for RPi itself.
