It can be powered from 3 x AA batteries (not included) or from an available USB power source such as a power bank, so there?s no mains power needed.

There is also provision for 12VDC power for permanent setups (power adaptor not included). Includes USB power cable. 360 rotation Colour changing USB or battery powered
