Firstly thanks for any information.

I admit that I have no idea outside of just spending an hour on google/youtube, the slang of all this.

What is the general settings/mode that I need to set this to? This is for my SO, and she wants more vapor and not such a burning sensation when hitting it.
Right now it is at 250 degrees on TI mode?

I tried the TC modes and really couldn't get into them. Right now I am using a RDA/Squank with a .5ohm coil at 50w and plenty of vapor. It is a single coil not a dual coil. Been using this setup for almost a year. I got tired of buying expensive fucking coils thus the Squank is the best of both worlds. Has a bottle instead of tank and RDA on top. Quick easy coil/cotton change. This coil has been in it almost two months. Changed out cotton a lot and still going strong.

ETA: Bump the TC up from 250 to maybe 325-350. Remember TC it to help you keep from scorching the cotton yet still has to have juice on it to avoid that.

Does the TC = temperature control? Do Ii adjust the ohms to .5?

Yes TC is Temp Control. If in TC mode you adjust it via the temp.

Thank you

Are you using the NRG tank that came with it? None of those coils are temp control and even if they were they would most likely be SS (stainless steel) not TI (Titanium). TI isn't a common coil anymore.

If they are the GT coils they're most likely running on straight wattage in temp mode since the device can't get a correct reading. Switch to wattage mode and check the wattage written on the coil. If she's using the 0.18 ohm mesh coil that came with the device the range is 50-85W and best between 65-80W. Start at 50 and work up till she finds something she likes.

It is the tank that came with it, and thank you. I am within that range now, and no complaints so far.
