I'm new with this mod. Can anyone tell me the different things I can do on the device and how to do them
You will want to refer to your USER MANUAL, which can be found UNDERNEATH the mod's cardboard 'holster' within the original box. Also don't forget to REGISTER your mod, with joyetech, so that if something should break, internally, beyond your control, you may have a chance of returning it and receiving a NEW model, free of charge. (manufacturer's warranty) So get that box back out!

The Evic VTC Mini has both WATTATE (AKA POWER) MODE, and it also has TEMPERATURE CONTROL MODE. Each mode is different in the way that it controls how you heat the coil(s). With Wattage/Power mode, you simply set your favorite/preferred wattage, and VAPE! Your preferred wattage will probably be different for the type of atomizer/tank/head you are currently utilizing. IF you are using an OLD style rebuildable atomizer, with a SMALL air-hole, you may want to use a higher MG Nicotine juice, at a LOWER wattage setting. I use 12mg w/my older, small airhole atomizer-heads.

IF you happen to be utilizing the TANK that CAME with the Evic VTC Mini, well then, you have the option of using it with HIGHER wattage settings. I recommend using a lower MG nicotine (around 6-9mg) and the airflow hole size will be dependent of your inhalation-style. IF you inhale straight into your lungz, you may like the middle or highest airflow setting. IF u are like ME, and u enjoy taking vapor into your mouth in a long, drawn-out drag, and then inhaling that vapor all at once, then you may like the tightest airflow setting, paired with a very SOFT drag, almost like a kiss...

WHETHER OR NOT you enjoy direct-to-lung or mouth-to-lung hits, if you want to use a higher wattage, u will need to experiment-with, and use, a lower MG nicotine juice, than u would use with an older stylized atomizer unit... It is worth it, because the vape is MUCH warmer, and the amount of nicotine vaporized per hit, increases substantially. Me, myself? I am still using 12mg juice, at 12.5W, w/the tightest airflow possible on my new Ego-ONE tank. u certainly have a TON of options to enjoy m'boy... NEXT, would be temperature control mode, which, I am not very familiar with. TC mode, (for short) allows u to vape like u would in POWER/WATTS mode, but it LIMITS the "temperature" so-as to deny the coil from burning your wicking material. It actually monitors the resistance of your coil, so-as to NOT allow the coil to reach a low-enough resistance to BURN your cotton. (dependent on your TC setting, of-course!) I am unfamiliar with how to set TC mode, so, I cannot give you a recommendation of what "temp" to set the device, or how to use TC mode, period!

You will have to experiment with TC MODE alll on your own. Hell, I shouldn't of said what I've said, this is YOUR journey to embark on! The Evic Mini is a fantastic device to begin vaping with. Enjoy your vaping journey, young man.
