Would it melt the insides if I solder the wires into the terminals

Depending on how long you spend soldiering the wire on ,shouldn’t be a problem though , properly terminated crimps are good enough though

Can this be used with a vehicle having +ve earth battery

I don't think so. The LED display is probably wired to work with conventional negative earth batteries. I would emphasize this is just my opinion. It probably could be got round but you would need to know what you are doing!

would this charge a macbook air via usb c port?

This charger can charge the macbook air via USB C Port , but you have to make sure your vehicles can provide enough voltage 24V, and use the original cables or third-party authorized cables. Normally, the truck, boat can provide more than 24V volatge. But it cannot charge the macbook air via the USB C port in MOST cars which can provide only 12V.
