coil or tank problem?

[Danny300]

Hi there, i have bought couple weeks ago in Las Vegas X cube 2 and TFV4 mini.
The first week i was vaping Clapton dual and sextuple coil with 80-90wats and it was amazing .
Big smoke and flavour at its best.
But after a week of using the taste was like getting burnt toxic.
So i changed it to RBA coil which was already built, it was okay for 1 day and then the bad taste returned, i cleaned the wire and changed the cotton, it did not help.
I rebuilt the RBA completely new and still nothing, can't enjoy the vape at all
Need help, what am i doing wrong .
P.S. After i release the fire button, i can still hear something burning inside the tank.

What kind of wire were you using when you rebuilt the rba?

With coil(s) like that (high heat capacity), it takes the coil a bit to cool down. Therefore, hearing a little sizzling after releasing the fire button, is normal.
Overall, you might be using too much power. Although, the coils are able to handle the power, it doesn't mean, your eliquid can. Not every liquid likes it hot.
Regarding the RBA, you might just have a wicking issue.

I used the wire which was given in the box for tfv4 mini tank.

Can you upload some pics? Usually, if you wash everything and out a new build and prime it well so you don't fire it dry fixes the problem.

OPINION: I don't know anything about the tfv4 tank, but, sometimes, it is the tank. If you decide to go with a different tank where you have a nice deck for you to build on yourself instead of relying on buying new coils, you should check out the OBS Crius V3 (with the velocity deck). You will never have any issues.
