    Dual coil ampere calculations

    When doing single coils, I calculate the minimum possible resistance with the formula R = E / I. Doing it with the maximum of 4.2 volts that my mechanical/battery can provide. Of course, I don't push it to that resistance, I am happy with around 0.8-1.0 ohms. What is the formula for dual coils...

    Tobeco Trident questions

    I got a Trident clone from Tobeco and like it a lot. It is my first rebuildable dripping atomiser. One thing though, the chrome plating is flaking off on the "tank". Is this of concern? What is the material underneath the chrome-plating, is it brass or stainless steel? It's quite hard to find...

    Will I be happy with a coil of 1.0-1.5 ohms?

    So, my first mechanical is coming and I apologise for the many questions I already asked but one thing has me wondering. People seem to like 0.7, 0.8 ohms on their mechanicals. I want to have my RBA's working on both mechanicals and regulated mods, so I have to have at least 1.3 ohms I think...

    Is this battery and the math safe?

    I am waiting for my first mechanical to arrive, including some Sony Konion US18650VTC4 2100 mAh. I also have AW lMR 18650's. I calculated the minimum resistance that I could use with either with the formula R = E / I.So, let's do this:AW lMR 18650 (assuming 10 amperage limit):R = 4.2 / 10 = 0.42...

    Nemesis clone - some questions

    Hi, I think I will get a Nemesis clone. I have a few questions about the Nemesis though:1. When locked (or unlocked?) you can see the battery vent holes. When locked, you don't. I searched and found that the button has holes in it but I can't see them on either the original nor the clones...

    The Rocket RBA: a good atomiser?

    I have been looking for a rebuildable atomiser to go along with my Kayfun Lite Plus and Fogger V3. I have been looking at The Kraken, the SMOK RSST, and recently The Rocket. My priorities are no leaking, easy access, and micro coil with cotton possibility. While all three have easy access for me...

    Help me go mechanical the right way

    I want to try mechanical mods and want to do it safe. Can you please point me in the right direction with the following questions? 1. Simple one: Tobeco Nemesis or Chi You? 2. Is sub-ohm every coil under 1.0ohms? Will I be safer with a 1.0-1.2ohms coil than say 0.7ohms, provided I have the...

    Questions about micro coils + cotton

    I have a few questions regarding micro coil + cotton builds. 1. Horizontal coils: what is the deal here? Are they supposed to be better in some ways? What are the benefits of horizontal micro coils with cotton? 2. If you forget about the liquid going empty in your tank and you use cotton /...

    Which batteries for regulated and mechanical would be best?

    I am a few months now into mods and have problems with my AW IMR 18650’s. All my mods (itaste SVD, Vamo V4, and Sigelei Zmax V3) turn off randomly at times. I heard it’s about the amp limit on those batteries. I have one other and the random shutoff didn’t happen with it yet but I don’t remember...

    SMOK RSST questions

    Reading ECF on the RSST it seems, this is a good purchase for me. A few questions: 1. How do you like microcoil+cotton builds on it? Do they work good? 2. I read it leaks from the center pin, does it also leak when laying on its side, out of the wick itself? 3. To what atomiser is the default...

    Normal coil with cotton?

    Hi everyone, I have a hard time perfecting my microcoils, as I am very new to them. Would you recommend wrapping a normal coil (32gauge wire, wire spaced out, not touching like in a microcoil) with cotton? I have spent at least 2-3 hours on microcoils right now and want to vape, so do you also...

    How many wraps with 28gauge Kanthal A-1?

    I ordered some 28gauge Kanthal A-1 to replace my current 32gauge NiCr wire. Or at least to try out different things. Usually, 5/4 wraps of 32gauge NiCr wire on a "doubled twice" 2mm silica (S-shape) gives me around 2.0 ohms. Let's say I want to have the same or a similar resistance with the...

    Voltage/wattage for a given resistance. I am a little bit lost!

    When I only had clearomisers, it was easy: bump up the voltage until it tastes burnt, then take it down a bit. Some time later, here I am with a Sigelei Zmax and Vamo V4, 2 ProTank 2's and a Kayfun Lite Plus. After reading a bit, I quickly changed from voltage to wattage and set it around 8.5...

    Will I enjoy the Fogger V3 RBA?

    I currently own a Kayfun Lite Plus (my first RBA) and a pair of ProTank 2's. I really started to like rebuildables and want to get another one, a less expensive model. I make my coils usually with 2mm silica and 0.20mm NiCr (soon 0.20mm/0.30mm Kanthal) wire. I looked at dripping atomisers but am...

    Help with coils

    I am fairly new to RBA and have a few questions. Please keep in mind that I am not really ready for micro coils yet. I have a Vamo V4 and a Sigelei Zmax. 1. Did I understand correctly, that the more wraps I do, the more liquid gets vaporised and that in turn increases flavour and vapour...

    Is a dark buildup on an RBA normal?

    I am having a dark buildup on the wick and wire/coil of my Kayfun Lite Plus. Does that happen with all liquids or should I be concerned? Thanks.

    DIY Liquid: What percentage of TPA Sweetener (sucralose based)

    Hello everyone, I am using TPA Sweetener and I heard anything from 1 drop per 5-10ml and 2+%. I tried 2% of TPA Sweetener and didn't taste much of a sweetnes. Would you go as high as 4-5% with it? Thanks and sorry if that talk is not allowed here :)

    Microcoil with silica

    Hello everyone, after reading the forums for some weeks, I decided to sign up! Indeed, a very nice and informative place here. My first question is, what are your opinions on microcoils with say 2mm silica instead of cotton? Thanks!
