Its all about wattage, right? Noob needs help!

[killovicz]

I've been only vaping for 13 days now never the less I made my first power mod today.

It's just a 3A voltage regulator (3V-15V) that I have connected to a 12V 1.5A power adaptor. I have connected it but did not tried it yet since I burned a fuse on my multimeter after the closing hours.

I made it so I could find different sweet spots for various atty's and catros.

Now to the point: If I find my own personal sweet spot for E2-R3's to be at:

6Vx1.5A=9W would this be equal to 3Vx3A=9W

In other words the voltage is just a way to control the effect (Watts) and the effect is what counts, right?

Thanks in advance, Killovicz

Opps forgot the quote

Sorry will respond further when more time exists. Short answer - watts ARE key -- but so are the ohms of your atty -- If you pull 9 watts at 6V with that atty -- you will NOT get 9W by putting 3 Volts to it.

It's volts times volts divided by ohms so 3*3=9 9/3 = 3 watts (very weak). Ten watts is often considered the sweet spot. So you first have to know the resistance of your atty or cartomizer.

for example 5 volts with a 2.5 ohm 5*5 25/2.5 = 10 watts = sweet spot. Now of course this varies from person to person and from juice to juice.

Right now my favorite is a simple 3.7 (14500 battery) with a 1.7 ohm cartomizer. 3.7*3.7=13.69 13.69/1.7=8.05 watts a little low but perfect for my favorite juices.

edit ohms being the resistance of the atty or carto

You have a voltage adjustable regulator I presume.

Just keep things simple output at 'standard' ecig volts. Start it at 3.7V and move the voltage up from there. 3A should be more than enough to find your sweet spot.

would this be equal to 3Vx3A=9W

To get 3Vx3A=9W you'd need a 1Ω atty. Ain't gonna happen. If you were using a 2.2Ω Joye 510 and set your reg to 3V, even though it has a 3A output potential the Joye would not do much (if anything at all). It would be pulling only 1.3A. To get a Joye atty to pull 3A you'd need to set your reg's output to 6.6V. If you set your reg to 3V and used a LR 1.5Ω atty you'd get about 6W. Not terrible. The LR would be pulling about 2A.

6Vx1.5A=9W

Now that would take a 4Ω atty, some of the HV atties are around that.

Does it matter that the power going in to the 3amp reg. is 1.5 amps?

WOW guys this was the most compact help I have ever received in my life , just few lines made the matter as clear as 1 + 1!!

THANKS YOU SO MUCH, I really Appreciate it , now I understand why ppl connect their batteries in serial rather then parallel.

Right now I only have R3's XL 2.4-2.6 Ohms (TPB modded) which I run on my eGo (3.4V when fully charged, lol) besides that I have some LR's and 510 atty's.

I made made my power mod partly because I felt that my R3's needed a bit more power to reach their full potential and partly to check these High Voltage Atomisers out (..and to find their sweet spots), they all run at 4.5 ohm's.

I was hoping that once I found the spots I could simply shag a voltage regulator directly into the connector (planning on making RCA connectors for my box mod) and be able achieve the right wattage regardless the power source! (as long as the min. input requirements are reached)

For example:

For my R3's which are 2.5 ohm's a sweet spot of 10W would be achieved by making a 510 connector with this regulator installed within the connector:

(5V x 5V) / 2.5ohm's = 10W

and for the 4.5ohm's the regulator should be at 6.75V, and so on...

------------------------------------------------------------------------

However I did not include the juice in this equation so my best bet would be to make a voltage adjustable box-mod. I know all this thanks to you guys, once again THANK YOU VERY MUCH!!!

@5cardstud

Not really sure yet, since I made my mod yesterday and burned a fuse on my multi-metre in the process. I'll hope to find out later today. Once I found it out I'll both PM you and post here about it.
