Millions of questions totally overwhelmed

[hobbette]

Ok so I stopped vaping when I found out I was pregnant. After I stopped breastfeeding I started again, but I'm so far out of the loop now it's ridiculous. I don't even know where to start.

My sister gave me an ego aio she wasn't using. She had dropped it a number of times and the USB micro port is not working right. I like the sub ohm coils and I'm looking to get something new.

I've been looking at the evic aio I like the changeable battery, remivable glass, tank converter and am interested in the rewickable notch coils.

The thing is I don't know anything about temperature control, vw, or the newer ni or ti coils. I am not really up to date on my batteries.

How does tc on the evic aio work? What exactly does it do? I get what the vw does, and the ranges are on the atomizers, but is it easy to use? Does it need
To be set much? Do the rewickable notch coils need to be tested when you wick them and do I need a separate tank to do that if they do? (I have a multimeter) What's with the ni and ti coils?

From the coils I've seen available the lowest being .25ohm I should be able to use a 20a battery for anything pre-built but I don't know much more than that. I saw the purple efest batteries were venting? Are litecigusa.com or mvs ok places to buy batteries?

I'm not totally sure if this is what I want or not. I would think I would like it since it uses the same coils as the ego aio, but seems more versatile, but I have a 1 year old so I don't really have too much time to mess around with it in general. It needs to be easy to use most of the time.

Welcome back. Please discontinue use of a battery with a bad USB port. That's a common reason for fires and such.

Welcome (back) @hobbette! Congrats on the new little one

Batteries - Mooch is pretty well-versed. Check his blog: Mooch's Recommended Batteries | E-Cigarette Forum Orbtronics, imrbatteries.com, rtdvapor.com - very good places. I've purchased batteries from 101vape, too.

Regarding TC, basically, think of the temperature as your limiter and the wattage setting as how fast you get to that temp. You can "floor" it, but when the coil hits your set temp, the device backs off the power delivery to keep you from overheating your coil.

How are you with Ohm's/Watts' Laws? If you're using Kanthal/Nichrome coils and only looking at the coil rating, I'd start about 1/2-3/4 of the LOW end and work my way up to what I like as a setting. If you hop into TC coils, I'd start with power at the low end of the coil rating, and set the temp about 370-410 and nudge the temp up until you find a spot you like. Then, you could play with the power setting - again, that's just going to get you to temp more quickly.

Hi hobbette. Welcome back.

In simple terms, think of VW like a Dimmer Switch on a Lamp. You can adjust it Up or Down to suit your Mood.

On an e-Cigarette, VW lets you adjust the Power, the Watts, that the coil produces. So you can adjust it Down for a Mellow Hit. Or you can adjust it Up for a Big more Intense Hit. And to find that Perfect Sweet Spot where a given e-Liquid tastes Best.

Once you kinda find a Overall Range of Watts for how you like to Vape, you will probably find that you don't need to Adjust it constantly. Just an adjustment here or there to Fine Tune the hit.

TC is like that Dimmer Switch. But it allows you to Set a Maximum of how High you can set the Dimmer.

The Purpose of TC is so you Don't get "Dry Hits". And so you can (if you want) run Higher Wattages/Temperatures without buring the Cotton Wick and your e-Liquid.

To use TC, you have to use a Coil Wire that's Resistance Changes a lot when it gets Hot. The Most Common wires for TC are Nickel (Ni), Titanium (Ti), or Stainless Steel (SS 316 or SS 316l)

Stainless Steel is Very Popular because it can be used in either TC Mode or in VW Mode. Whereas Ni has to be used in TC Mode Only.

I don't use TC much. I just don't get Dry Hits in VW Mode for the Coils and Wattage I use. And I'm not trying to Push the Coil to Maximum performance. But I tell people that Most Mods come with TC. So you should try it and see if you like it. And if you do, use it. And if you Don't, just use VW Mode

The Ohms of a Coil are Very Important when you are using a Unregulated e-Cigarette ( a Mechanical Mod or "Mech" Mod).

For a Regulated e-Cigarette, one that you can Adjust the Wattage or run in TC Mode, the Ohms of your Coil are Not important when thinking about Amps that you Battery will need to provide. It's the Wattage that the e-Cigarette is set to and how many Volts the Battery has that determines the Battery Amp Draw.

And for a Single Battery Regulated e-Cigarette, this is around 60 ~ 70 Watts.

At 60 Watts on a Regulated e-Cigarette with a Battery at 4.2 Volts (Fully Charged), the Battery will need to provide about 16 Amps regardless of the Ohms of the Coil. And at 60 Watts with a Battery at 3.4 Volts (Fully Discharged - Needs to be Recharged) the Battery will need to provide about 19.6 Amps regardless of the Ohms of the Coil.

Last Thing. I would Retire that eGo AIO with the Bad USB Port ASAP. It just isn't worth Fooling around with something like that.

I would just look for a Mod that you like the Size and Looks of. And that is in your Budget.

Thanks for all the replies! 1st off I'm not using the ego aio but I appreciate the warning.

I know ohms law but not watts I'll look it up after posting this if the kido doesn't wake up.

I knew ohms law in reference to mech mods because that's what I had before, and never really thought about the vw changing things though now that you mention it I feel like I should have. Would watts law be the equation you use to determine how many amps you need? 19.6 seems really close to to 20 and I belive the evic aio is supposed to go up to 75.

What advantage do the ni and ti coils have over ss?

For Me, None.

And I like the Taste of SS over either Ni or Ti. It just tastes Cleaner to me.

Watts are really just a calculation. It's voltage x current. In respect to resistance, it's voltage squared / resistance.

Variable voltage is like a dimmer switch on your lights. When you change the bulb to a different wattage, the light is brighter or dimmer and you have to adjust the dimmer. In an ecig if you put in a coil with a different resistance, you have to adjust the voltage to compensate.

Variable wattage is like a dimmer switch that detects the light level. If you change the bulb to a different wattage, the dimmer adjusts the voltage so that the light level stays the same. In an egic, the ecig adjusts the voltage for you.

Temperature control is like a dimmer switch that detects the heat given off by the bulb instead of the light produced. If it gets too hot, it turns down the voltage even to the point where it's not lit up anymore. This protects the light bulb.

Of course, the ecig can't actually measure the temperature of the coil. It does it indirectly by measuring the resistance, which changes as the coil heats. Not all metals will change resistance, so you have to be using the correct wire and you have to set up the ecig so it knows what resistance equals the wattage you're looking for.

A common thermometer doesn't measure temperature "directly". The mercury expands with increased temperature, and the amount of expansion is measured to get the temperature. So a tc mod actually measures the temperature no less directly than a mercury thermometer.

Yeah... When a person stops and Thinks about it, there Aren't too many "Direct Measurements" of Heat.

Welcome back and congrats hobbette

I've found the easiest way to calculate amp draw in VW mode is to use the Steam Engine battery drain calculator.

Click on 'regulated (APV)', 'power regulation (VW)', input the 'Power (wattage) setting' (try 75 watts for example), set 'Battery voltage' to 3V and hit enter. In the 'Battery drain – what taxes your battery' box you'll see battery draw is 27.78A at 75 watts. I use 3V because that's when your batt is about empty. Try it at 4.2V and you'll see it is less, the opposite of how it works with a mechanical mod.

Experiment with the watts, resistance and battery voltage and you'll see how battery amp draw changes with each in VW mode.

TC works the same for max battery draw as it's limited by the watts you set. It may be lower if you set a low temperature, but it will never be higher than the watts set.

What advantage do the ni and ti coils have over ss?

Ni and Ti change resistance more as they heat up allowing more accurate coil temperature control. With the current mods out there it is probably not worth worrying about though.

Disadvantages: both of these oxidize when over heated and that oxidation may be unhealthy to inhale, which is why we don't vape these in VW mode. SS is considered safe enough in this regard.

I also find both Ni and Ti harder to work with when making coils.

Best of luck with it all

Wonder what my Laser thermometer indirectly reads..

I just stick my hand in the oven. Surefire way of knowing if it's hot.

There is another advantage of temp control than avoiding a dry hit. If you're in power/wattage mode, the mod will continue to supply whatever power level you select to the coil for as long as you hold your finger on the fire button. That means your vape becomes hotter the longer you press fire, sometimes uncomfortably so. With temp control, once the coil is "at temp" the mod will regulate the power to maintain the same temperature throughout the puff, no matter how long you press the fire button. It's a smoother vape for me.

That would be Heat.

What is attempts to Directly Read is Black Body Radiation.

Hence the emissivity setting.

But somewhere in these snippets there's a joke mentioning a zipper of some sort.

Thanks for all the replies. I can't think of any more questions at the moment but I'm sure I'll have some when it gets here [emoji14]
