Has anyone used a surge protector on the charger?

I thought I posted about this but couldn't find anything in my history. I had an issue where my charger's plug started to melt. No idea what caused it, but after having the plug replaced by Porsche and replacing the outlet with the one recommended in the forum and also lowering my charging to 35 amps, I have not had any issues. That being said, I saw these surge protectors meant for RV's (link below) and I'm wondering if this would be a good option to protect from a future surge or whatever may have caused the melting. Any thoughts?

Probably not related to your previous issue. The melting was likely due to heat for a prolonged time, not a surge.

You can add a whole house surge protector to your electric panel. Two of them (1 for each 110v side) install like breakers and have a green LED that indicates they are operating. They just need to be matched to your panel.

Good for the entire house.

As @365B said, you can add surge protection for the whole house. I had two installed as part of a whole home generator project last year. However, I don't think surges would create heat. They are momentary in nature and tend not to have a lot of total energy (just high voltage). Suggest having an election check the quality of the plug, socket and the connection. For high current service, the plug needs to have a very tight fit with the contacts in the socket. If not, arcing can occur creating heat. Also suggest confirming amperage spec on your plug to make sure its within spec.

Good luck

If you've a melted plug, it's built up heat and that means somewhere inbetween and including the receptacle and the plug to the evse, there is too much resistance.

The receptacle could have bad contacts, i.e. perhaps there is a lot of plugging and unplugging which is resulting in a weak contact between the prongs of the plug and the receptacle.

The plug it self could be undersized for the amount of current it is pulling. Given the fact that running lower current prevents this problem, this helps to reinforce it is a resistance problem.
