Scary electrical buzzing sound when firing... (sound file attached).

[lukewheeler]

So every now and then, my PV will emit a very quiet buzzing sound when firing my atty. It'll happen for a little while, then stop. Then the next day, it will begin again at some point. To be honest, it might happen more often as I don't always vape in dead silent environments.

Functionally, I haven't noticed any change — no heat, no issues with the quality of the vape — but I know it shouldn't be making this noise. It doesn't sound healthy.

I'm using a Vamo V5 with a Rocket rba, and the battery currently in it is an Efest 800Mah 18350. I don't have my Efest 18650 to try out at this moment. I've charged these batteries several times since I first noticed the buzzing and they seem fine.

Any ideas? I've attached a sound file in which you can hear the buzzing sound fairly well.

Thanks guys!

P.S. I just removed the battery, put it back in and the buzzing seems to have stopped... maybe I've answered my own question.

that is your coil firing im 95 % sure maybe someone else will chime in . I dont think you have anything to worry about .are your ohms staying consistent if so dont worry

Are you able to hear the slight buzzing sound behind the usual sound of the coil firing? It's not a sound you'd expect to hear alongside the normal sound.

And funnily enough, my ohms do seem to be changing... it's been going up and down between 1.7 and 2.1 over the last few days.

Best thing to do is pop another atty on the Vamo, to check if it's the Vamo buzzing or the Rocket.

RBA's like the Rocket can make some seriously strange noises at times

It sounds to me like the (I dont remember the technical term) where the power to the atomizer cycles really fast up/down, up/down. My SVD does the same thing. Its supposed to do that. Sounds like a super fast clicking electrical noise. Some mods have it and some don't. Someone will come in and say what the technical name is cause its escaping me right now.

Pulse Width Modulation?

you should fire the rocket before reassembling. That sounds like your coil firing.
