Is the Surface charging cord extensible?

Hey Tribe,

Quick question: how exactly does the Surface (RT, but I'm assuming it'll be the same for the Pro) connect to its charger?

Most charging cords are a lot shorter than I want them to be, and in the past I've used simple USB extenders in between the actual charger and the charging cord to extend their reach, and I'm wondering if I'll be able to do the same for a Surface.

If it connects to the charger some other way, or if the cord can't be separated from the charger at all, are there any long Surface chargers (or just cords) out there that I could get instead?

Thanks
