Welcome to the Dell Community  @Sherbet66 

Because your laptop has a "SMART" battery having an "Original OEM" USB Type-C Power Adapter should not be  that important anymore.

What is important is to make sure you have enough power for your system.

Since we are just starting to get laptops with just USB Type-C power adapter ports I have not been able to do much R&D yet.

And no one has reported any errors like "The AC adapter wattage and type cannot be determined" when using a "Third Party" adapter.

Best regards,

NOTE: Any comments and other information would be very welcome!!!

USB type C PD chargers are standard, so third parties should be compatible. However, Dell's 130W is over the standard which ends at 100W, hence you won't be able to find one; even 100W ones are still rare and expensive these days. And in addition, Dell's compatibility tens to be iffy. For the regular XPS 15, 60W@20V PD chargers work mostly, of course the laptop is in a restricted-power mode.

I know I'm super late to the party here, but I just bought an off brand charger, a GAN5 BASEUS that is able to charge at 140w, but my 9575 just reads it as a 65w charger in the BIOS. So Dell is intentionally limitting te charging capacity, and I know this because the slow charger connected notification does not pop out when I use this charger, despite only showing up as a 65w charger....
