The odor is significantly reduced to a much more faint smell. Combustion produces tars and carcinogens, which is the cause for a portion of your smell. Since the process of vaporization produces an aerosol mist, the smell isn't as powerful. The Vapir Mini Oxygen Vaporizer 4.0 does a fair job of managing smells.

The battery must be charged for 12 hours. Do not exceed 24 hours, this will over charge the unit and void the warranty.

The 4.0 now features a coaxial cord connection vs. the 3.0 version used the RJ31 (telephone cord) connection.

This is significant, the biggest complaint with the previous model was that the RJ31 (telephone) connector would sometimes break.
