HELP to new Kanger RBA (ROOKIE)

[xxGET_REKT_M9_xx]

Hey guys.
i just bought a new Kangertech Sub mini kit today. And for the first time i used the included rba that came along.
after a few errors i made a coil that worked properly and here is where my quistion comes:

my mod is a Joytech Vitech 75w. and using the stock coil and stock cotton, on a 70/30 pg, liquid i got 0,49ohm on 22w - 3.48V.
when i did a re-fill on the atomizer - NOT the cotton, it now says 0,55 ohm, without me changing ANYTHING - is this normal ? or is 80/20 a bad mix for a rba build ??
please help me out ... (i do not own anything to measure ohm, etc.)

It's perfectly fine.

how come it changes OHM only on a refill? tought i was going to burn the cotton on the higher OHM ? ... :/

I don't know...
Lower ohm coils burn hotter than higher ohm coils, so you're more likely to burn your wick with a lower ohm coil.

what should be the "best" ohm radios to be in? iam a 0,5-0,6 ohm vapor, in pre-build coils.
so i guess 0,48-0,60 is a good place for me ?
i just dont wanna ruin' my build ... and trying to get some fifs, off of you guys.
Turotials are great, but the dont anwser my quistions ..

also - thanks for the replys so far!

Hi @xxGET_REKT_M9_xx and welcome to the forum. I usually build my RBA on the subtank mini from .4 to .5 as a preference. Some coils will change slightly with a little use. I wouldn't worry about small changes. If you are concerned, you can always open the rba up and double check the tightness of the screws holding the wire, one of the most common causes for ohm fluctuation. You tube is a good resource for tutorials on coil building. The subtank mini is so easy to use you'll be expert at making the coils where you want in no time.
I use this steam engine to configure my coils : Coil wrapping | Steam Engine | free vaping calculators It's a good reference to bookmark. Good luck.

Thanks buddy. well i tighten the screws fairly, to the point where "the bite" or grips ..
the link for the coils is way out of what i know, i just build .... iam not at all that deep in what thread , diamenter and stuff like that xD but i'll use it when iam a bit over rookie stage thanks!
great tip for the screws. if it keeps increasing or lowering i might have to open the top, to check.
thanks for the great help!

*NOTE*
is it normal a 80/20 Will couse dry hits ? on 25w and above ?
just checked the wick and it was okay. - but going above 25w gave me dryhits ? YUCK! 1st day, and all ready some dryhits :'(

The rule of thumb for any vape device you will own is the same. Start low and work your way up. With my Sub mini rba @.4 to .5 I usually vape in the area of 22 to 25, mostly 22 and 23 watts. Each juice is different. If you're getting dry hits at 25 watts back it down one or two, the juice won't vaporize as fast. You just have to search for your sweet spot. Personally I don't get caught up in the numbers to the point of where I "need" to be vaping at a large number, I just find what works for me.

It's a combo of wicking, ohm rating and power, and will take some time to find your comfort zone.

iam getting smarter and smarter!
Thanks!
well, i tought it would be much in whats "in the numbers" but i can hear its all about ones personale style, and what each person likes!
thanks again!

Tighten the screws again. And otherwise don't worry. The difference you're talking about is .06 ohms. That can make a difference with super low builds, but not in the 1/2 ohm range; and is in any case probably below your mod's ohmmeter accuracy.

This is a great wicking method. You may have to tweek it a bit to your preference and definitely to fit your RBA. I have run it up to 40 watts in the Subtank without dry hits using 70/30.

gotta tighten the screws tommorrow !
- the Pancake methode looks super cool! and sounds like it would work with my VG based juice, might give it a try tommorrow ! (Y) super cool!
thanks.
