Damn! I Keep Blowing Attys!

[MBblue]

Alright, I'm official stumped. I just got a Chameleon high voltage device and it runs perfectly at 3.7v with no problems. However, it also operates at 6v and (I believe) 7.4 volts with the extension sleeve. The problem is that every time i try to run it at a higher voltage than 3.7v, be it 6v or 7.4 it will burn really hot with a bad taste for a hit or two (even with a good amount o juice on it) then the atty just stops working. This happened with multiple 510 attys as well as a 901 high voltage atty. I really want the 6v sweet spot but I don't want to keep burning attys. Someone please help me.

Ah yes, the downside (in addition to safety issues) of high-voltage devices.

High voltage is very demanding on an atomizer, which is the most delicate component of a PV. Some attys (varying by manufacturer, date, batch, and individual unit) are sturdier than others. vaping is an industry still in its infancy (which is part of the excitement of participating in it). And quality control is not all that it should be.

Using an HV atomizer can help. [HV = "high-voltage," but it actually is high resistance.] It dampens the power ... down to around 10 watts* (which is what most vapers regard as the "sweet spot").

* Typically it is referred to as "5V", referring to the net voltage of a 6V battery package with a built-in resistor or regulator. With a standard resistance atomizer, such a device also delivers approximately 10 watts of power.​

Don is quite right here. HV vaping still has bugs to be worked out. In general HV vaping shortens the life of attys. Allow me to add some useful math that can act as a gauge.

Not all 510 attys have the same resistance. The ones I have from TW are consistently 2.5 ohm. Others state that their 510 attys are 2.2 ohms. LR attys are 1.8-2.0 ohms I think. DSE510 attys are generally around 3.0 ohms. HV attys are generally higher than 3.0 ohms.

As Don said, its wattage (power, P) that is the key, not voltage.

P = V^2/R, where V is volts, and R is ohms. "Sweet spot" is particular for the person, but there seems to be a general attraction to 10-12 watts...although my sweet spot is around 6 watts, and that can be too much for me sometimes (I'm a light-weight). A 2.2 ohm atty at 7.4V, will be giving about 24 watts on the coil. That's a huge amount of wattage on the atty!! So it would be useful to measure the atty resistance with a multimeter, if you have one, and see if this might be why your problems are occurring. My guess is this is the reason. Unless you can lower the batt voltage, you are likely going to need HV (high resistance) attys, and there still might be considerable strain on them. A multimeter, especially when you start getting into mods, is quite useful.

Good luck!
