The Eleaf iStick 50W's compact size makes it very convenient and portable, but it also packs many amazing features, including variable wattage with 50 Watt maximum output, 0.2ohm resistance capability, and a beautiful OLED screen. Powering the iStick 50 Watt is a beefy 4400mah Li-ion battery which can be charged via mini-USB port on the base of the device.
The RX200, a new version of Reuleaux series, designed by JayBo, still features the use of three removable 18650 batteries and reverse polarity protection. However, the new and powerful chip has a maximum output of 200 watts and advanced temperature control functions including Titanium, Nickel and Stainless Steel modes. The upgradeable firmware and vibrant color options separate this from the rest.
