It adopts a dual-circuit drive design inside， which can effectively control output while monitoring temperature of the atomizer. With the new monitor technology， HFDMR-Ni200 (High-Frequency Dynamic Monitoring Resistance of Ni200) ， it can achieve the high accuracy of regulating and monitoring heating wire temperatures. The precision can reach 10 degrees Fahrenheit (about 5 degrees Celsius). Constructed from stainless steel with a zinc-alloy coating， it looks modern and feels comfortable. Magnet-held battery cover design makes sure that， with a gentle touch， you will simply slide it off and replace the battery in seconds! This compact mod takes one 18650 battery， and provides 60 watts of maximum output for enough power! This is KOOPOR mini， helps to satisfy all your desire for temperature control， strong power and high quality. God said， "Let there be light"， and there was light. You said you want real temperature control， and there is KOOPOR Mini.<br><br><span style="font-size:17px;">Note: </span><span style="font-size:16px;"><span style="color:#ff0000;">This item will be shipped after Oct. 10th</span></span><br><br><b>Dual Driver System</b><br>Recently， most devices on the market have "single driver system"， which means that it' s only one option， either boost or buck the voltage. However， KOOPOR has integrated our own Dual Driver System that works to buck and boost the voltage to improve the accuracy and speed of regulating， and enhance the consistency and taste of every puff. Or let me explain that by using a metaphor: other devices can be compared to front or rear wheel drive vehicle， and KOOPOR to all-wheel drive， which tends to produce a more outstanding<br>performance.<br><img src="http://des.gearbest.com/uploads/2015/201508/heditor/201508181715542386.jpg" alt="" /><br><b>High-frequency Dynamic Monitoring Resistance</b><br>HFDMR， is a high-frequency resistance sensing technology， which can detect atomizer resistance once every 250 microseconds， with a precision of approximately 4000 times per second， thus regulating the temperature of heating coil more effectively.<br><img src="http://des.gearbest.com/uploads/2015/201508/heditor/201508181715551369.jpg" alt="" /><br><b>TC Mode and VW Mode</b><br>KOOPOR Mini allows you to switch between VW Mode and TC Mode as you like.
