DESC: This iron has 1600 watts of power for a powerful steam output. 3-way smart auto-off switches iron off in 8 minutes if left vertically, 30 seconds if left horizontally, and 30 seconds if flipped over. The 8.5 oz. larger transparent water tank allows for fewer refills and a clear view of water level. Anti-calc prevents build-up of water impurities for longer life of the iron.
