Multi-voltage adapter passthru (2000mA too much?)

[ibi5205]

My project this weekend is to make a passthru using a multivoltage adapter from Radioshack. It will allow me to vape at 4V, 5V, 6V, 6.5V and 7V. The adapter puts out a max 2A (2,000 mA). Is that too much for my 901 atomizers?

I assume not, since the amount of current flowing is not necessarily the full 2,000mA, being dependent my voltage setting and the atomizer's resistance. (Current = Voltage/Resistance) Correct?

Has anyone used those high-voltage 901 atomizers that I saw at MyVaporStore? They are supposedly for use with 6V or more. Are those for real? I might like to try those with the 6.5V or even 7V setting on my adapter.

By the way, I tried posting this in the Battery mods Forum, but I seem to be unable to post anywhere but the New Members Forum, even though I joined one year ago and have posted in the Battery mods Forum before.

Many thanks.

i like the idea of a variable voltage passthrough better than a portable battery style one.

It shows you only have 2 posts. to get out of the new members section you have to have at least 5. New rules to limit spam bots and spammers.

You set the voltage.
The atomizer you're using has some particular resistance.
The voltage and resistance determines the amps drawn by the circuit.

I = V/R

A power supply capable of 2 Amps is ...sufficient.

Yes, I knew is would be sufficient; I use a Kensington battery pack that puts out 1.5A. I was just worried it might be too much.

But, like you said, the amount of current drawn will depend solely on my voltage setting and the atomizer's resistance.

Thanks.

It's all about watts. Looking for that 8 - 10W sweet spot. More or less.
Using a 'high voltage' atty seems to make sense if you are looking for that 3.7 experience, at 5V. Or was it the other way around? Wish everyone would place watt ratings on their attys/cartos.

P = EI = I²R = E²/R

I = E/R

There is a post around here that shows all the various attys/cartos and their resistance, with watts calculated.

Hmm, at least I seem to remember one. Maybe it was a daydream?

Hafta look around...

I remember reading that a LR atty on a 3.7volt will give you somewhere around 9.3 watts

And since I had a couple more regarding attys open:

I am confused. LR vs HV?

I know that HV is high-voltage (in our case, 6V+). What is LR? I'm thinking low-resistance?

I asked a question about standard 901 atomizers vs. the HV atomizers. I get replies comparing high-voltage vs. low resistance atomizers?

What am I missing?

lol - I feel ya.

I believe it goes like this.

HV - High Voltage attys/cartos, have a higher resistance, this keeps the current draw down so you can use it at a higher volatge without a resultant increase in current frying them. Used, for some reason, on high volt mods, like 5-7V

LR - Low Resistance attys/cartos are made with a lower resistance so you can get a "high voltage" experience out of lower voltage, used to get the 5-7V feel, on 3.7V.

Wouldn't be confusing if everyone simply rated their attys/cartos on min/max Watts.

Generally speaking folks are looking for a 'sweet spot' around 8 - 10 watts.

Different attys/cartos have different resistance, so different current draw at same voltage.

This is why vari-volt devices like the Buzz, are likely to become more standard, so you can 'dial in' the amount of power to your atty/juice combo, getting the sweet spot in differing situations.

How about an example (random ohm value) Lest say 3.0 ohm is a normal atty, and 1.5 ohms is a LR atty:

3.0 ohm atty/cart @ 3.0V = 3.0 watts
3.0 ohm atty/cart @ 3.7V = 4.6 watts
3.0 ohm atty/cart @ 5.0V = 8.3 watts
3.0 ohm atty/cart @ 6.0V = 12.0 watts

1.5 ohm atty/cart @ 3.0V = 6.0 watts
1.5 ohm atty/cart @ 3.7V = 9.1 watts
1.5 ohm atty/cart @ 5.0V = 16.7 watts
1.5 ohm atty/cart @ 6.0V = 24.0 watts

So basically, with a 1.5ish ohm atty, you get the 5V experience of a 3.0ish ohm atty, but at 3.7ish volts. YOu are essentially vaping at "High Volt" with your "Low Volt" batts.

Assumming of course, that the battery can supply the current.

As far as the HV attys/cartos go, I don't understand the purpose.
