How to read power chart (for VW) and choose wattage?

[ohaya]

Hi,

I was looking at this power chart:

http://25.media.tumblr.com/tumblr_m9dkanCt0I1qc8949o2_1280.png

Am I correct that the way that this is used/read is that for a given resistance and a given voltage, the numbers inside the cells/boxes tell you the wattage?

And you want to be in one of the green boxes?

If that is correct, then that seems to mean that the "good" wattage range changes as the (for example) voltage changes. for example:

- At 4.20V, the "green" wattage range is 4.41W - 8.02W whereas

- At 3.70V, the "green" wattage range is 4.28W - 7.61W

Is that correct?

So, to stay in the "green" wattage area, you'd want to, say, set the battery wattage (for a VW device) to 4.41W - 7.61W?

Is that correct?

Thanks,
Jim

Yes. Although I use the left colume first to determine what my resistance or ohms is. Then I go to the right and see what my volts range is. I set my volts in that range.

Some flavors/taste do better at the low end of the range and some at the higher range.

A 2.2 of resistance (go to the right and see the green zone. Look at the minimum/maximum wattage. (4.09 - 8.02 Watts) OR, look up to the top and see the Volts range. (3.0-4.2 Volts)

Hi,

Thanks. As mentioned in the OP, I'm looking for setting for a VW device, not VV one.

The chart works for determining volts or watts. Different people prefer or have to use one or the other. I was just trying to reach others, too. Good chart.

the chart is for average coil/wick setup ( like a Protank, etc) My HC3.1 normally runs in the 7-9W range but my RSST likes it better in the 10 - 12W range due to the heavy bed of cotton. Considering the mass of the wick and surface area covered by the coil will determine what wattage is "best" for the given wick/coil. The lower end watts showed in the chart doesnt have enuf heat to properly vaporize the juice, while the upper end (red zone) will burn the juice as it vaporizes.... which ends up being unpleasant...
The choice of juice and the PG/VG ratios also play a part in the wattage setting too....

there are alot of variables to consider other than "add juice set to X watts and vape" ...

I'm not a welder, but I use a technique similar to those guys. I play with output without even looking at it; most of the time I can hear the right condition. It's not foolproof and I might have to tweak for some flavours, but most of the time I can just listen, and for any PG/VG ratio or any kind of flavour, it's usually correct when it makes the same sound. Not interested in using some chart; that would be like taking a sex-ed book to bed!

Sometimes I get a juice "pop" like biting a grape or sausage casing. Now I'm hungry. Anyway, wondering about viscosity, pg/vg mix, temp, draw technique and chart. I have bdc that are sold as 1.8 but show 1.9 on MVP. I draw and hear the sizzle, then the pop and stop. That is at 7w, too hot on the chart. I change to 6w and loose the pop but less sizzle. My passthrough was set to 4.2 so I changed it to 3.7 and get the same thing. No pop but the flavor is not as intense. What to do, what to do...

It really depends on the juice. Some flavors taste horrible at low wattage and others burn really easy. Depends on the wick too. If you use cotton like I do, it's really not fun when you burn it. I use my protank 2 between 9&10 watts.(rebuild the coils myself with 30ga)

IMO, the charts are just suggestions not rules, the green areas arent ideal for everybody or every combination of juice & delivery device.
Whether you use V or W makes no difference, set the power low and slowly work your way up until you find the vape quality you're looking for.
If you get a slight burnt taste turn it down a little.

My chart is my tastebuds...

These charts are fancy.... Well made... Nice to look at...

But after 1 day of vaping....

Completely useless!

Start low... Make your way up in volt or watts until you like it. Any atomizer can go around 8 to 10 watts without any problem.

I have to agree with this. I always just tell people to start at the lowest setting your device allows. Usually that is 3 watts and far to low, but the great thing is, you can turn it up one click at a time until YOU find what YOU like. I see many people say to start off at 7 watts with a 2.5 ohm stock head in a Protank 2. For me, that is WAY to hot. I rarely, if ever, get past 6 watts, and find my "sweet spot" to be generally 5-6 watts. Once you get to the setting that the juice taste's off or bad to YOU, just back it back down to the setting that was the best for YOU.

I can't stress enough that it is about what YOU like, and not what anyone else says or a chart displays.

Now I am done with my allotted amount of uses of the word YOU for the day. lol.
