So your on the beach on a sunny day, and your umbrella is actually powering your stereo. Cool right! The Sunbrella provides a source of energy to power small appliances using Photovoltaics that produce a peak output of 282 watts.(A standard CD/cassette player takes 30 watts) Just plug your small appliance in to the Umbrella’s plug and your in business. It also comes with a built in fan for additional cooling on hotter days. Other features include detachable parts for easy flat storage, and a drill anchor for an easier set up.
