High Ω Coils

[HDVaper]

I was rebuilding some old coils last night and 2 out of the 8 I did turned out to be 3.2Ω and 3.3Ω (got a little crazy on the wrapping I guess). But they looked so good (wraps) that I hated to tear them up and start over again. My question is will the work OK at the higher Ω or should I re-do them? Thanks in advance.

It won't hurt anything to use them. They'll draw less current and run a little cooler than your low-resistance coils.

 

[UncleChimney]

They'll still work fine, may have to turn the voltage up though!

 

[HDVaper]

Thanks!! I just did another one and it came out 2.8Ω. Guess I'll take it down a wrap! Thanks again.

On an unregulated device or at the same voltage.

Those should work fine. You just have to match the voltage to get that preffered taste and vapor. Most likely 5+ volts.

 

[Vapo Marx]

For a given voltage, a higher-resistance coil will draw less current and generate less heat.

On an unregulated battery, the voltage will tend to climb slightly if less current is being drawn from it.

Try 'em! You might like it! (Assuming you have a VV or VW device.)

 

[ScottP]

If you have a VW device it won't matter at all. You device should automatically adjust the voltage to get the correct wattage you want. If you have VV then you may need to adjust the voltage up some manually. If you have neither then it will be a cooler vape but will still work.

I use 3(ish) ohm coils in a RDA on my Provari all the time. Every bit as nice a vape as LR coils on a mechanical.

I do want to throw this out there too. While using a VV/VW device that 3 Ohm coil can be made to fire exactly like a 1.5 Ohm coil, to do so requires more from your battery. From a battery perspective, it will last longer firing a lower voltage on a lower resistance coil than it will firing a higher voltage on a higher resistance coil. The vape is the same the batter life is not.

I run micro coils 3.2ohms - 3.8ohms at 1 volt higher then the ohms (running atm 3.5ohms at 4.5 volts) and it is great.

If you are talking long term impact on your batteries that's actually backwards.

On a regulated device, any difference in life at the same wattage is not related to the load per se but the efficiency of the converter at that voltage. So it's not inherently one way or the other. They are likely to be very close regardless, since the wattage demand is the same.

Maybe you should give a bit more info before you state that as most common coils used then you would be wrong.

Volts: 4.5 / ohms: 3.5 = 5.78 watts / amps 1.28 (current setup) MICRO COILS high ohms (most common)
Volts: 2.5 / ohms: 1.5 = 4.16 watts / amps 1.66 (micro coils low ohms)
Volts: 5.5 / ohms: 3.5 = 8.64 watts / amps 1.57 (no micro coils high ohms)
Volts: 3.5 / ohms: 1.5 = 8.16 watts / amps 2.33 (no micro coils low ohms) (most common)

I agree with Rickajho. It may not make sense, but lower resistance allows more voltage to flow to the coil, so the amperage draw from the battery is more. Higher resistance means their is less voltage going to the coil, thereby less amps used by the battery. At least that's the way I've always understood it. I'm sure dr g will set me right.

Low resistance = more amp draw
high resistance = less amp draw

 

[ScottP]

There has to be additional current used in the upconvert process though. Taking a 3.7v battery and using a booster to push more volts from the battery requires more power. It doesn't just come from thin air.

I built a solid 1.2ohm coil in my zap and it fires at 4.2-4.4v tops on the provari mini but gets an E2 error on my other two non-mini Provari's. Was there any subtle amperage limit change from v2 to the newer mini's maybe?

The provari has a 15watt limit for v2.5 idk about 2.0, 1.2 ohms at 4.4 volts is 16.13 watts I am surprised you can even do that.

 

[RedhatPat]

I know right! I've been vaping it for days now @ 4.2 (14.7w) but just turned it up to 4.4 and still fires! (on the new mini only) How can a steady solid 1.2 ohm pass the 15watt barrier on a 'vari is what the mystery is here, folks. Sorry for hijacking the thread
