Hey everyone, new to this. Question about iTaste vv3?

[Paul William Carr]

I was using a 2.5 ohm coil I purchased from a local vape shop that was supposedly a dual coil. When pressing the fire button, it would heat up relatively quickly (~.5-1 second). Recently I purchased a new tank that came with a 1.5 ohm dual coil. I've noticed with this coil it takes about 2 seconds before it heats up. For the record, I did also start using a higher VG juice that is far more viscous than my previous juice on the 2.5 ohm coils. My questions are:

1. In many reviews I watch online the coils on numerous devices seem to heat up instantly. Is it normal mine would heat up more slowly or is my device defective?
2. If it's normal, what might be causing mine to heat up more slowly if lower ohm coils are supposed to heat up more quickly?
3. If low resistance coils are easier to heat, why will they not fire on some cheaper batteries?

Any help or advice appreciated, thank you.

The V3 has an output limit of 11 watts, so at 1.5 ohm it will send 4.06 volts through the atty at highest setting.

Since this is dual coil, each individual coil has a resistance of 3.0 ohms. 4 volts through a 3ohm coil will take a bit to heat up. I think it is working normally.

What power setting are you using? If you are at say 9 watts, it's running at 3.6 volts and the coils would take a long time to heat up. Turn up the power and see if it works faster.

To specifically answer your questions...

1. Many videos show mech mods being pulse fired. You don't notice but the coils are already warm, then the guy hits the fire button and is like "yeah look at em glow". Then you make the build yourself, and it takes 1-1.5 seconds for them to glow. That's been my experience. Also, they don't have to glow to produce vapor. Actually once wicked and juiced, your coils shouldn't glow at all.

2. Lower ohm single coils heat up faster. A 1.5 ohm coil heats faster than a 3ohm coil. But you are using dual coils. This means each individual coil is 3ohms. This is why it is taking longer to heat up than you expected.

3. The lower your resistance, the more amperage is drawn from the battery. Cheaper batteries may not be able to provide the amp or watt output that is required by the low ohm coils.

Thank you so much for your reply, it has been difficult to get such clarity. I normally keep it between 8-10 watts but honestly didn't notice much of a difference in taste or vapor production when running at 11 watts, just felt a bit warmer. One thing i'm still confused about is if the 2.5 ohm dual coil has a higher resistance than my 1.5 ohm dual coil, why does the 2.5 ohm dual coil heat up faster? In theory, shouldn't that total 5 ohms and the 1.5 total 3 ohms? The shop I purchased the 2.5 ohm coils from for my evod glass said they were dual coils but is it possible they were just wrong?

I would guess that they were incorrect and those 2.5ohm heads are actually single coil.

What type of atomizer are you using on the itaste v3? Kanger, Itaste, Smoke? Clearomizer, Carto, etc?

Sorry for not specifying that right off the bat. Here's the story:

My original setup was an evod glass and battery. Typical noob set up. Was vaping that with what I would imagine was a high pg juice. Not sure of the ratio, but it was rather watery. When the coil needed to be replaced I went to my local shop. Showed employee1 the coil and he said kangertech had replaced those with newer, better designed dual coils. Buy a couple and leave.

Get home, coils won't fire. I know nothing about vaping, bring them back to the shop and employee 2 takes a look. Says the resistance is too low and asks employee 1 to grab the higher resistance coils (2.5 ohms) of the same make. Take them home, they work great.

Recently I purchase an itase vv v3, protank3 mini (1.5 ohms stock), and new juice. New juice is very viscous, assuming it's very high VG. Set it all up, seems like the coils don't fire up very quickly. Toss the evod glass with 2.5 ohm coils/old juice on it, fires up pretty quick. Not instantly, but faster.

And here I am. I also have a nautilus mini on the way with stock 1.8 ohm vertical coil in it so I plan to use that for comparison.

Hrm, check out this photo of both single and dual coil heads.

Does your 2.5ohm head look the one on top or botton? The one on bottom is dualcoil, top one is single.

Check the resistance of your heads using the itaste. It will show you the actual reading. Maybe the 1.5 head is faulty.

I recommend rewicking with organic cotton, will taste much better with a possible slight increase in vapor production from my experience.

Welp, that settles that. Got home from work and compared coils. The 2.5 ohm coil IS a single coil. They were wrong. Was drivin me nuts, thanks so much for clearing that up, porkchop! Now all things considered, when I go to order more replacement coils, what resistance do you suggest? I would like to be able to generate the most vapor I can while still utilizing the full capabilities of my device.

Hey congrats on getting this figured out. For the V3 or MVP2, get either the 1.8 or 2.0 ohm heads. That will keep the mod within spec all the way up to 11watt max.

Can't thank you enough, really appreciate it..
