Question on volts, watts and ohms

[Grimjack]

Just got my Vamo in the mail and looking for a good guide or rule of thumb on volts to ohms, and what role watts plays? I have a 2.0 ohm atty in currently, what would be a good volt setting, and how do I decide going forward? And where should my wattage level be?
Thanks!!

The simplist explanation that I have found is this article, which also includes the Safe vaping Power Chart, which can be used as a general guideline to choose the best ohm coil for the voltage or wattage you desire. Just find the ohm rating that has the largest number of green blocks for your desired voltage/wattage range. The average number of vapors seem to prefer around 8 watts. A good ohm to start out with a variable voltage/wattage device would be between 2.5-3.0 ohm.

So I'd start with a little disclaimer: any voltage/wattage setting is personal preference (ie, some people like 10 watts, others 7; some people like 4 volts on a 2 ohm atty, others 4.7). With that being said, here goes:

1) A general rule of thumb for voltage to ohms, is add 2 volts to your resistance. So if you have a 2 ohm atty, start at 4 volts.

2) Watts and voltage are related by the resistance (aka ohms). They are not really independent of each other, but rather, as you adjust volts, watts will change (assuming you're resistance (ohms) is staying the same). Mathematically (and this may not be important to you, but if you like numbers), Watts = (Volts x Volts)/Resistance. So, if you are vaping a 2 ohm atty at 4 volts, Watts = (4Vx4V)/2ohms = 8 watts. Watts is also known as power. So, lets see the watts of a 3 ohm atty at 4 volts. Watts=(4Vx4V)/3ohms=5.3 watts.

3) With the Vamo, if you are vaping in voltage mode, you will have to adjust your volts up or down depending on your atty's resistance. If you find that you like vaping at 8 watts, then whatever atty you are using, you can use the above formula to figure out what voltage to set to get that 8 watts. A lot of people however don't even think/care about watts...the voltage is simply adjusted to taste and throat hit.

4) Also with the Vamo, if you are vaping in wattage mode, it will adjust the voltage automatically to continue to give that wattage. So, if you like vaping at 8 watts, and you have a 2 ohm atty on it, the automatic voltage that the Vamo will using is 4 volts ((4Vx4V)/2ohms=8 watts). If you stick a 2.5 ohm atty on there, the Vamo will adjust its voltage to around 4.5 volts ((4.5Vx4.5V)/2.5 ohms~8 watts) so it will continue to give you that 8 watt setting.

Finally, again, the wattage/voltage setting is totally up to you. It's whatever you find you like the most. Some juices you'll see work really well with high wattage/high voltage, others may taste burnt and you will have to lower the setting.

Volts is input power

Watts is out put power

If you are in VV mode, you have to calculate the Watts based on your ohms.

If you are in VW mode, you don't have to calculate anything.

VW mode is what you want with that device.

Dude just double the ohms to get the right voltage and you can add .4 on either side to get the ideal range. 2ohm atty = 3.6 to 4.4 volts w/ the sweet spot being @ 4.0 to 4.4. Easy.

Around 4v or 8-8.5 watts. Watts is a calculation of power, so lets say right now your using your 2.0ohm carto at 8 watts which is around 4 volts or so. If you swapped to something with around 3ohms you have a higher resistance therefore you need more voltage to keep that 8watts. So by using wattage settings your device automaticly ups the voltage to compensate for the higher resistance.

7.5 to 8.5 watts btw is probably where you should stay/

I would say start at like 6 watts and work your way up I like 8 watts most of the time. It always better to start low than high and pop a coil! I might drop to 7 depending on the juice and if I am chain vaping for a few minutes. I like wattage cuz I dont have to always be messing with my volts and like vanillagurilla said you can put any resistance on at say 9 watts and it will put the voltage at what it needs to be. For my 1.5 cartos I like 8 to 9 watts which is 3.4641 volts at 8.5 is 3.57071 volts and 9 is 3.67423 volts. Like vanilla said again 2.0 ohms at 8 will give you 4 volts. I have also heard of taking whatever resistance you got and adding 2 so for example 2.5 ohm that would be 4.5 volts. I would use ohms law calculator just google it. Also check out pbusardo on youtube and tastyourjuice(dot)com Here is a chart so you can know what you're looking at and the red area in this chart is a little early for safety reasons on his or her parts. http://25.media.tumblr.com/tumblr_m9dkanCt0I1qc8949o2_1280.png Here is another one https://store-549f5.mybigcommerce.com/product_images/uploaded_images/voltagechart-lg.jpg

I have to agree with ego-sum-deus on this. Volts x volts / resistance = the watts setting that will give you a base to start with. From there it depends on your juice, some work well at that formula and others can go higher or lower from that. A lot of the juices that I use go from 5.5 to 6.5 watts and any higher gives me a burnt taste or won't optimize flavor. For example, my Kanger EVOD/ProTank 1.8 ohm heads recommend 3.1-3.4 volts, 2.0 heads at 3.5-3.8 volts, and 2.5 heads at 3.8-4.2 volts. So at 3.3 volts for the 1.8 head I get 3.3v x 3.3v / 1.8ohms = 6.05 watts. Most of my juices are just fine at that and can go a little higher, but a couple of my juices will taste burnt if I hit 7.0 watts.

I had the same dilemma recently and stuck with volts for a while. However I'm now a "watts convert". I have various heads and tend to vape somewhere between 7-9 watts. Just play about with it a bit - you'll find your own sweet spot.

just requires a little bit of simple math
don't overstress it

Yep exactly just take it easy and like before start low use the calculator and charts but start at the lowest and go up until u find something that's working and then maybe bump it up if its to hot and you don't like just go down .5 or 1 watt or .1 .2 volts pretty much back to where you were at and you will start to find out what's good. Hope everything is goin good and you're having a good vape. Somedays it might seem like its not the same as the day before and others it might seem too high. Your taste will change all the time I thought I was having problems with my device or carts and juice but I just played up and down a couple times didn't notice but the usually hotter and less vapor and cooler so I was right back at my setting 8 watts had something to drink and 30 mins later the flavor and everything seemed great again. Moods can change your vaping habit trust me!!! LOL

Happy Vaping

hey crew so i am kind of new to vaping and kedp forgetting what volts i needed for each coil i used so i just made a small android app to calc it. it is free app and with no ads so i am getting nothing from this just trying to help the community out.
