Newbie here and still trying to understand how all this works. I bought an ac200max to power my van build. Currently the only thing I use it for is to power my Iceco 75L fridge and charge phone/laptop. The fridge is plugged directly into the 10a cigarette lighter port (or whatever this is called). I am planning on connecting other appliances such as a maxxfan, composting toilet, water pump, overhead lights, diesel heater, etc. I was wondering if I need to connect a small fusebox between the appliances and power station of if that is something built into the device? Thank you for tolerating amateur questions
