There are a couple of Razer Blades up there; they say incompatible:
Dart is not compatible with laptops that:
Draw > 65W of power
Require a voltage outside of 18-21V
Have a non-standard connector
We may have a tip or product that works with this laptop later, please join our Notification List for updates.
