Koopor Plus 200W Hissing noise??

[Andromendous]

When I turn my mod on and its unlocked, if i put my ear up to the top side of the battery door, i can hear a "hissing" or "buzzing" noise. Its very quiet, but i can definitely hear it if i put it up to my ear like its a cell phone. Can anyone check theirs and see if its doing this?


Im guessing its the chip located there making this slight noise. Once the screen goes off and the mod goes to "sleep" the noise goes away.

That would be the regulator(if your firing the mod) - Normal............and it is Not a Cell Phone.
Just for safety sake, I would not place a Mod to my Ear and fire it.

I never fired it while next to my ear...

I fired it next to my ear once........ but I never inhaled!



I seem to remember a few mods doing this.

I have heard others refer to it as the "heartbeat" of the mod.

Is it a higher pitch noise? I remember reading other threads and people were saying it was the displays on certain mods.

The only way i know how to describe it is, i used to have some Bluetooth ear buds that made a similar noise. But its barley noticeable. I just wondered if it was normal

I'm not hearing that on mine, but my HF range may be compromised after decades of playing guitar on stage.

I can hear the sizzle of the coil if I press fire while my ear is next to the top of the battery door. BTW, the Koopor Plus must have a higher frequency voltage regulator. The coil sizzle is as smooth as my Provari V2 (800hz).

thats the batteries moaning under the duress of 200W

That must be it. I'm vaping at 10W and hearing snap, crackle, and an occasional pop.

If you listen closely you'll notice once the display goes off the "hissing" or "buzzing" goes off. Its really nothing to worry about, I had the same problem and at first was concerned about it as well.

Yep.

Switching regulator noise perhaps? Many regulators and digital displays have a clock oscillator (lo frequency) that runs all the time...controls the timing pulse of the regulator and can also double as a display driver trigger (to simplify the part count).

It's the sound of electrons doing the nasty
