1.8 ohm coil running 2.5 ohms?

[Moonlitwish]

My coolfire 4 is telling me my resistance is at 2.5 but the coil is rated at 1.8. Is this normal?
Yesterday it said it was at 2 and I didn't think much of it since that's not much difference but I'm pretty sure it shouldn't be increasing...

I find that my coils ohms will go up as the coil gets gunked up. Sometimes in a day and sometimes much longer. The length of time depends on how much I have vaped through it and the sweetness of the liquid I am using. Clear liquid tends to burn cleaner than darker liquids. Lots of variables to consider.

If your 1.8 ohm coil is reading 2.5 ohms there is most likely a problem with you tank/clearo/RTA/RDA. Check for loose connections and/or replace the coil.

Also clean the 510 connection with a Q-tip and some alcohol.

Thanks guys! Resistance is creeping back down now so when I empty this tank I'll take it all apart and clean it up. I run clear menthols so my coils usually last 2-3 weeks. This is the first device I've had that gives me that info so I didn't know what to make of it.

2.5 ohm reading with a 1.8 ohm coil is not normal what so ever. You have been given some good advice already. I did want to mention though that often when I change out a coil in my Kangers they read .2 ohms higher than they should. Once broken in they read correctly. I will say I have never seen them read that high though (2.5 ohm).

Is it a stock coil or one you wrapped? Either way it could just be a bad coil, hot spots and the like causing the ohms to jump. Replace it.

Is it a Kanger Aerotank/Genitank with the Airflow Control Base that has 5 holes? V3 Base?

Always make sure that the base of the coil housing is secure. Ohm "jump" can be as much a result of poor coil wire contact as anything.

Something us squonkers know TOO well.

So far that I've been checking, I've not had a single Kanger coil read right! Not for my aerotank or my subtank mini. But the difference has been about .2 like you said.

All stock. Not quite to building my own yet. I chucked the coil. The new one isn't vamping as nice, but maybe that's because I now have the subtank to compare it to.

I recently discovered with my Orchids that if I unscrew the contact point (vocabulary) on the bottom of the RTA, use a pin to insert some Ox-Gard (conductive grease) into it, and re-install it, that the reading goes down to what it should be.

I build all my coils to 1.8. As the coil gunks, the resistance goes up. I've had my current coil for about 10 days and it now reads 2.2. As long as the vape stays good, I don't really care.
