Hey everyone, my 1st Q ever here on ECF. Hope someone can help.
I've been vaping about a year and have a few devices. I'm buying an Aspire Nautilus 2 tank, using the 1.8 ohm coils (recommended 10-14 watts). Getting back to the MTL roots so to speak. I plan on powering the Naut 2 with my Vaporesso Target Pro 75 mod. No worries there I don't think, as the mod has variable wattage, volts, TC control, etc. I also have a good iJust 2 battery section laying around doing nothing as I broke the original tank. So here's the big Q: Can I also just screw the Naut 2 tank on the iJust 2 battery (yes, 510 compatible). The iJust 2 kit is sold as a sub-ohm device with either 0.3 or 0.5 ohm coils (30-80 watts). Will the iJust 2 battery just automatically account for the much lower wattage and higher ohms of the Naughty 2 coil? Obviously the iJust 2 mod section has no settings or adjustments, simply on or off. Will it work, or will I just start frying the 1.8 ohm coils?

According to Sweet Vape's website, it just sends straight battery voltage to the atomizer without changing it. The battery voltage will drop as you use it, along with the wattage. A freshly charged battery with a 1.8 ohm coil will give you about 9.8 watts.

"Eleaf iJust 2 Battery is a tiny sized, high amperage battery that can fire 0.3 Sub Ohm Coils. This is similar to joyetech ego one batteries in that it's not variable voltage, it is straight voltage from the battery (4.2v Fresh Charged). It has a small body, and contains a 2600mAh large capacity cell. It also features a spring connector to ensure good connection."

Unfortunately No, the iJust 2 does not make any Adjustments for the type of Atomizer/Coil that is attached to it.

This is Not to say that it Doesn't or Can't work with you Nautilus Tank. But if the Hit you get is Too Weak or Too Strong, the only thing you can do to change the Hit you get is to Change the Coil Resistance you are using.

I wasn’t arguing that an N2 could be used on a fixed battery. I’ve used mine on a T22 fixed at 13 watts.

I didn’t think the N2 would work very well on that particular battery, the iJust 2. And it’s not really a fixed battery, I don’t believe.

I know resistance range stamped on the coil isn’t gospel, but the 1.8 is rated 10-14w. The iJust 2 is 30w minimum up to 80w. From what I understand it is somewhat like a Mech.

I plug in watts and 1.8 Ohms and the voltage and amps don’t seem right.

If I’m wrong, disregard everything I’ve said. But it would seem to me the N2 with 1.8 coil wouldn’t be the optimum match for the iJust 2 battery.

I think where the Confusion and Misconception occurs is that a Mod doesn't really Output Watts. It Outputs Volts.

And the iJust 2 just outputs the Voltage of it's internal Battery when the Fire Button is Pushed. Just like a Mech Mod does.

So a Freshly Charged iJust 2 will output just under 4.2 Volts. And ever time the Fire button is pushed, the Voltage will Drop slightly. Until eventually the Voltage reached the Cut-Off Limit. I think on the iJust 2 this is around 3.4 Volts. Maybe a tad lower.

So if I put a 1.8 Ohm Atomizer on a Fully Charged iJust 2, I would create 9.8 Watts of Power (4.2 * 4.2 / 1.8) at the Atomizer.

And right before the iJust 2 is Drained, a will not Fire anymore, I would be creating 6.4 Watts of Power (3.4 * 3.4 / 1.8) at the Atomizer.

The iJust 2 isn't Outputting any Wattage, it just Outputs the current Voltage of the Battery when the Fire Button is Pressed. Regardless of what the Resistance of the Atomizer is.

Whereas when you press the Fire Button on a VW Mod, the Mod reads the Resistance of the Atomizer first, then it does some Math, then it adjusts the Voltage so it jives with Ohms Law, then it Outputs the Calculated Voltage so the Watts created at the Atomizer Match what the Number the Volts are set for on the Mod.

But Once again, a VW Mod Isn't outputting Watts. It's Outputting Volts.

    ^^-- YES, except that some manufacturers are describing them in a way that confuses all that. Within their system only, it is slightly descriptive and at least gives the power ballpark.

    It is possible to make a battery unit with boost voltage that would be necessary to get excessive power through a 1.8 coil the size (and cheapness) of an iJust, but it wouldn't be able to drive deep subohm, for that it's either direct drive or maybe PWM reduction.

    I understand all that. And that would be correct if it were a true Mech. My confusion came in that the advertised firing range is 30-80w. If it acted as a true Mech the firing range would just be advertised as max 80 watts, because the wattage would be completely determined by volts and Ohms. Why does it put the minimum firing range at 30w? Is that just giving the optimum range? I assumed it meant there was some kind of regulation in the mod.

    As you said in your previous post, if you use the 1.8 coil and the vape is not good, you have no choice but to change the Ohms. That’s why I said the 1.8 coil may not be the optimum setup.

    Again, I might be wrong.

    I think a Couple of things are going on when it comes to that 30 ~ 80w Numerical Range.

    I believe it is Based on a given Coil Resistance. Because you Can't calculate Watts if you don't have a Resistance. So the People in Marketing took the Low Voltage cut-off and Voltage of a Battery with a Fresh Charge and set a Wattage Range. In the 30 ~ 80w case, it was based on a 0.30 Ohms coil. Which is what I believe came in the iJust 2 Kit.

    They Also, true to OEM form, they Exaggerated the Wattage on the High End. Because there is a Pervasive Mindset with a Lot of Vapers that Higher Wattages means a Better Vape.

    Also, New and Newer Vapers don't think in Volts. They Think in Watts. But sometimes there is a Disconnect that a Mod, Any Mod, is Outputting Watts. It's Outputting Volts. Watts is the Power Created at the Coil.

    If you want to talk about Wattages with a device like the iJust 2, there has to be a Low Wattage Limit no matter what coil resistance is used. Because unlike a Mech that will just keep Firing until the Battery Voltage goes to Zero, the iJust 2 has a Low Voltage Cut-Off to protect the Battery.

    I like to refer to Devices like the iJust 2 as Semi-Regulated. Because they Do Limit the Voltage the Battery can Discharge to. And they Do Limit the Ohms of the coil a user can use. But it Doesn't do Anything to change the Output Voltage the Battery is providing. So in that sense, the Output Voltage is just like a Mech.

    ---

    Yeah... Unless someone is a Very Low Wattage Vaper (VLWV), a 1.8 Ohm coil on an iJust 2 isn't going to probably get it done.

    But a 1.1 or 0.9 Ohm Coil like I have used on my iJust 2 Mini is OK. And the Size of the iJust 2 Mini coupled with a Small RTA like the Serpernt Alto makes for a Very Small and Compact on-the-go setup.

    Hey, thanks everyone for all the input. It's good to see so many active participants on this forum! Well I received my N2 Yesterday, put in the 1.8 coil, filled it, and fired it on both my Target mod and the iJust 2 battery. The iJust 2 battery worked fine, just as good as it did on the VW Target set at 10w. Sludge Van Diesel, mcclintock, and zoiDman seems to be the most accurate of all the answers. I'm not an unintelligent guy, but I glaze over when discussing Ohm's Law lol.

    Good to hear Tortuga.

    At the End of the Day, what comes out of the drip tip when one presses the fire button is All that Matters.

    Thanks. I wasn’t trying to debate you, I hope you didn’t take it that way. I understand that 4.2 volts with a 1.8 coil is right in the wheelhouse of the N2. I just questioned if the device would do that, or if there was some cutoff at 30w.

    Only reason I chimed in is at one time I considered this unit, but the info on it seemed a little vague, as with the 30-80 power range. I opted for Zelos and iStick 30w.

    Not at All. Just saw it as the Normal back n' forth whenever Specs or Technical things are discussed.

    Hey how do you like your Zelos? I have had my eye on that Mod for awhile. It has just been pasted up for New Squonkers on my last couple of buys.

    I like the rotating board. Long battery life. Reads attys accurately. Charges quickly. Nice and small. First one I bought was doa. Screen wouldn’t display. Had to exchange.

    But I like the iStick 30w better. The iStick has slots on the top. So there’s a little airflow under the atty. with the Zelos tank sits flush on top of mod. If I do a little chain vaping, the heat from tank transfers to the top of mod. Doesn’t do it so much with 30w.

    Also I use a few T22 tanks with no airflow adjustment, but has air slots on tank bottom. Zelos flat top blocks more of the air.

    Cool. Sounds like a Nice Mod.
