William, 33, the second-in-line to the British throne, started working with East Anglian Air Ambulance (EAAA) in July.
EAAA has requested people to donate 55-inch televisions so the team can relax between callouts.
The charity is also appealing for a large larder fridge, under-counter fridge, under-counter freezer, dishwasher and microwave for a new two-storey operations base at Cambridge International Airport.
Until now, Prince William and the crew were using a small room at the back of the main airport building as a base.

The Facebook appeal reads: "EAAA needs your help! "The crew and clinical team are moving to our new base at the Cambridge airport very soon. We are asking our lovely supporters and generous companies to help us furnish the new accommodation."
A spokesperson for the EAAA said, "We are a charity and don't like to waste money where we don't have to. A lot of business like to help us by donating items in this way."
He flies and responds to emergencies in Norfolk, Suffolk, Cambridgeshire and Bedfordshire, ranging from road accidents to heart attacks.
