The KangerTech e-Smart Clearomizer is a clearomizer that is the same diameter as the KangerTech e-Smart Battery - 320mAh, but it has a standard 510 thread that allows it to be used with many different setups.

Simply unscrew the mouthpiece from the top of the clearomizer and fill the outer portion of the tank.  Be careful not to get any liquid into the center tube as this is for airflow only and any liquid that gets in will simply run out the bottom or will be sucked up on the next draw.  Once full, screw the mouthpiece back on the clearomizer and screw the clearomizer onto the battery.  Give it a minute for the liquid to wick in properly and you are ready to vape.
