    Its a cheap 2 bay trustfire -- I've already ordered a nitecore and am planning on using the trustfire as a backup. But I loaded my 18650 in it and it's making a very audible whine. Is this reason to be concerned (or downright terrified?) or just normal?

    Well, my original Joyetech eGo charger does the same since day one. That's why I charge overnight in a ceramic pot just in case.

    That's been reported for a long time with (blank)Fire chargers. It doesn't appear to indicate any real problem, but it makes those 12 hour charge times even more annoying.

    Being so in love with vaping, the high pitch whine is a siren's song to me.

    I have the same charger and it has done that ever since I got it almost 2 years ago. I was actually going to mention it on here, so great question. I've never had a problem. Mine seems worse when you first put a battery in it and then the noise slowly tapers off as it charges longer.

    thanks, 'preciate the replies. Yeah, it is less now than before, still audible though. I feel better but not comfortable enough to leave it charging overnight.

    on the subject of charging, I don't have any metering equipment ... am I in the danger zone as far as not knowing whether I've overdrained the battery prior to charging? I'm using Ego T 18650 and anyvape 18350 battery tubes with Ego T and Evic Easy heads.

    It's either capacitor whine or coil noise

    Coil noise - Wikipedia, the free encyclopedia

    Computer people and anyone working with electronics and coils wrapped on ferrite beads for transformers know this sound all to well...

    It shouldn't be a problem...other than being annoying as heck!

    It is fixable...but ONLY by someone who knows about electronics and knows what they are doing!!! (aka putting a dab of clear nail polish in the coil which soaks in, dries and binds the coil so it doesn't vibrate)

    The Ego-T 2 heads have the same low battery protection circuitry as any Joyetech 510 or eGo battery: it shuts the device off when the battery voltage has dropped to 3.2 volts.

    Not sure about the Evic head.

    The whine isnt going to cause anything to explode, it's just a sign of less then top notch build quality. It doesnt mean poor build quality, just less then the best.

    OH SNAP!

    eVic Easy Head is the EXACT same thing as a Totally Wicked Tornado RCS!!!

    It DOES have the low voltage cutoff just like the ego

    Question...does the 18650 go in that eVic Easy Head battery tube? The Totally Wicked RCS uses a 14650 battery...

    Found it...the eVic Easy Head dual mode uses an 18650 battery

    Another side-topic: how do we get us a sub forum for EgoT 18660/tornado/evic easy genre of mods/apvs? Seems like a fair amount of market convergence going on around these interchangeable heads and tubes using the various control heads. I've got a couple compatible 18350 tubes for these comin. maybe there isn't a whole lot to talk about that's distinct from other mods but... let me know if I should be looking for such other than in the evic subforum and thanks for the input with the questions above

    My first trustfire charger made that sound too. I continued to use it with no problems. The power cord eventually got damaged (unrelated to the noise, just do to me putting to much stress on the cord due to the position I had the charger in while using it). I used it for over a year, and then went ahead and ordered a new one since the cord was shot. The new trust fire doesn't make that sound.

    Whether it's dangerous or not depends on the frequency of the whine. Certain materials resonate at different frequencies, and depending on the frequency and the function of the materials in question, it can be dangerous.

    It's somewhat similar to vibration analysis in rotating equipment like cam shafts, chain drives and shafts that drive large pumps (don't ask me how I know this). If you get the right frequency delivered to a piece of equipment that doesn't like that frequency, the results can be as spectacular as they are catastrophic.

    I saw a 120cm stainless steel pump shaft virtually disintegrate because the shaft of the engine driving the pump put out just the right frequency in its rotation.

    I can hook you up with an engineering outfit that specializes in this sort of thing, but just getting them to answer the phone will cost you more than the charger is worth, by a factor of about 5,462.

    Don't ask me how I know that, either.

    Harmonic Resonance Instability...



    Yeah..little vibrations can become BIG vibration can become catastrophic failures!
