Up to 1 cubic feet or about 75 cigars The Cigar Oasis Ultra electronic cigar humidifier is designed to mount on the lid of the humidor with minimum space requirements. It uses microprocessor technology to measure and control the humidity accurately and can run on either batteries or electricity. When used with battery power, it will run until the desired humidity is reached and then goes to 'sleep', which helps to extend battery life, and will sample the humidity every five minutes to make sure the humidity is correct. When operating on line power, it samples the humidity continuously. The unit comes with a sealed water cartridge mounted and is ready to use.
