You have to look up the maximum wattage for the given cabin configuration. I’ve found 30W to be about as high as I can go without it cutting out. Use a phone charger for your laptop.

This is where it’s helpful to have a multi-port charger where they’re not all high-draw.

IMO more important to go with something flat or light that won’t fall out under its own weight.

Assuming this is USB-C ports, they're supposed to negotiate a supported power limit with the device you plug in. If the port is saying "I can deliver 60W" and then cutting out if you draw more than 30, there's something wrong with their chargers.

I'm assuming he's talking about the mains socket.
