The Zelos raises the bar when it comes to compact mods. Coming in with 2500 mah battery, and an output of 50 watts you can be sure to have the vapor production and the duration you wish. You can find elegance in the simplicity of this device; with just three buttons you can navigate and personalize the settings to your taste. The device also comes with a USB connector, which makes it easy to charge on the go. The Zelos is sported in 3 different colors, all of which are made of anodized aluminum; black, grey, and red. Design was very important in the process so we have made the Zelos an ergonomic design with the soft metal feel, to allow for a snug fit in your palm.
