Sigelei 20W Too Hot is this normal?

[JamJarPenguin]

I just got a new sigelei 20W & I tried to use it with a dripping atomiser (LR 306) on the lowest setting 7Watts, but it gets the atomiser so hot I'm scared to use it. The volts going to the atomiser showed as around 3.27V (which is below the max safe limit for the attie of 3.7V). And the atomiser seems to produce hardly any vapour on it. If I swap the atomiser onto an SVD the vapour production is massive on 4.5W's & tastes good.

What is the resistance of your atomizer?

It's not firing it at 3.27V. It can't step the voltage down that far.

It was reading it at 1.6ohms. I've just tried it again & it is reading it at 1.4ohms & saying it is firing at 3.13V. I tried to read what is said as I press the button just now & it changes up to 3.77V & it does fire. Also I tried my nautilus on it & the ohm reading kept changing. It doesn't account for the attie having changed until I fire it (Is this normal?). The nautilus attie is 1.8ohms but the reading seems to swing between ohm readings until after about three or four separate button presses (with pauses in between, not in quick succession). 1.4 - 2.1 - 2.5 -1.8. And now after writing this I checked it again & the Nautilus is reading at 1.9ohms another button press & it is 1.8ohms again.

The LR 306 reads at 1.5 ohms on my SVD
The Nautilus reads at 2.0ohms on my SVD

The SVD rarely changes its mind about an attie resistance between button presses.

edit & the Sigelei now thinks the Nautilus is a 2.0ohm attie again. oh now it is 3.2ohms!

The 20W will not step down voltage so your minimum voltage is the voltage of your battery under load. It also reads working voltage in real time where your SVD does not. I would not use low resistance atomizers with the 20W unless you build them yourself. For off the shelf products, I don't think low resistance atmoizers will tolerate the 20W for long.

Are you saying both the 1.8ohm Nautilus & the LR 306 at 1.5ohms are both not to be used with the Sigelei 20w?

You might be able to get away with 1.8 ohms on a pre-built, but you will be putting a lot of power through it so your mileage may vary. I wouldn't go below 2 ohms unless you build your own. Again, until the battery starts dying down your are putting 4.2 volts minimum through it (around 4.0 working volts) even if you set the unit well below that (again, the 20W can not step the voltage from the 4.2 volt battery down). The voltage and watts that are displayed when firing are what the atty is receiving, which is much more than the 4.5 watts you like on the SVD (without doing the math, about twice as much power).

So basically Caged you're not answering my concerns of a problem with the device in my first two posts. But instead informing me that it doesn't have step down & as such I shouldn't be using a Nautilus or an LR 306 with a Sigelei 20W. Incidentally I am well aware of the Sigelei's lack of step down as evidenced by a thread where I specifically asked if this would be a problem with a Nautilus before I purchased & was told no.

Amazing, because I have seen forum user after forum user state that they use a Nautilus with this device. Not once have I seen anyone caution against it. Thanks for your input & I think you & I are done caged.

So if some one else can offer some insight on the actual concerns asked about a problem with my device in the first two posts that would be fabulous.
