This versatile mod reigns supreme over all other vaping hardware. Crafted with a lustrous stainless steel finish, the Monroe features a wide range of output options to heat concentrates at optimum levels. It adjusts from 3.0 to 6.0 Volts in 0.1 volt increments or 3.0 to 15 Watts in 0.5 Watt increments, and a maximum output of 4.0 Amps.\r\n The Monroe also enables users to switch between RMS and mean value voltage monitoring – RMS repeatedly samples the output voltage while powering an atomizer and adjusts for heat-related voltage drift.\r\n Monroe also features a native eGo-style connector that allows you to use both 510 and eGo-style clearomizers, atomizers and tanks without adapters*.\r\n\r\n*The eGo-style connector does not have outside threads but typical eGo style parts fit flush down into the recess that is around the Monroe connector. 510 Tanks and other similar 510 items will screw in and be almost flush with the top. The Monroe will accept Flat Top or Button Top batteries. Never use non-rechargeable batteries in any device. Only use the recommended batteries for this device.
