Do I need to buy a battery for the Heated Sleep System?
Yes. Each device in our Heated Sleep System line is powered by 12V rechargeable power supplies, and they do not come with a power supply included. All products connect directly to a standard 5.5 x 2.1mm barrel plug. Check the details for each product to see what adapters are included or available.
