One thing I've been paying attention to recently is how Tesla's wall charger is priced compared to Porsche's
On their website Tesla sells their Silver Wall Connector for $500. That doesn't include how much installation costs with an electrician. Along with that you can also purchase their Corded Mobile Connector for $520 or their Gen 2 Mobile Connector Bundle for $275 if you want.
For Porsche the wall mounted Charging Dock for the Mobile Charger costs $470. It also doesn't include installation costs.
Along with that, the Mobile Charger Connect that comes standard for initial production Taycan orders costs $1,120 on the Taycan Configurator.
