[NAME]  For optimal performance, the XPS 15 is designed for a 90W power source if you do NOT have the NVIDIA GPU in your configuration, or a 130W power source if you do.  Either way, it will run at reduced battery charging speed and likely reduced performance from a power source as low as 60W.  So what is the maximum wattage output of the outlets on the planes you usually fly on?  60W USB-C chargers are not expensive or difficult to find, and they could even be useful as overnight chargers, or last-resort power sources while you're using your system on land.  I know that Lenovo systems specifically have an "Airplane charging mode" that reduces their power consumption for this specific reason, but I haven't seen an equivalent on Dell systems.
After hours on the phone with Dell and a saleperson at Best Buy I decided on a Dell XPS 15 as I needed as strong a laptop as I could get but I needed to be able to do extended work while on a plane.  I was assured this laptop would be able to be used and charged on long flights.  I am on my first flight since purchase right now and I am unable to charge the laptop as the charger draws so much power it trips the outlet.  I am on Delta in the first class cabin if that makes a difference. Is there a charger that will work for this laptop so I can actually use it for extended flights or do I need to return the laptop? It is an XPS 15 9510. Thanks.
