    The end of microcoils?

    According to this Ulbrich Ni200 datasheet it is stable up to 600° and it takes extended exposure at the 800°F–1200F range for it to lose ductility and precipitate carbon. For what it is worth, I cleaned some Ni200 well with alcohol and torched the bejeebers out it. The surface changed from...

    SXmini M Class (TEMP CONTROL)

    Vapro Supply is the U.S. distributor for the SX Mini according to their YiHi SX Mini facebook page. I could be misremembering but I think they were the ones that were schlepping pre-release S-class models to trade shows. YiHi doesn't likely doesn't have a list of Vapro's customers who would be...

    Titanium wire, vaping and safety

    There is the DNA40 Chels side by side XvoStick by MiniEcig (YouTube demo). They have an ECF supplier thread, Mods by Chels - mini-ecig.

    Temperature Control -- Worth the Hype or a Gimmick?

    There has been no shortage of people who have struggled with doing reliable builds for temperature protection that have had a long, successful track record of doing Kanthal builds. Anyone new to temperature protection deserves to know this before spending their hard-earned money on a temperature...

    Hana Modz DNA40 V4S (skinny!)

    If someone is not planning to use their battery for anything that needs 30 amps the 20 amp LG and Samsung batteries are a safe choice for DNA 40 devices. DNA 40 specs/url] indicate a minimum 16 amp battery requirement so the 20 amp LG and Samsung batteries are within spec.

    Temperature Control -- Worth the Hype or a Gimmick?

    Temperature protection isn't a gimmick in that it provides a distinct vaping experience. However, not everyone will enjoy or appreciate that experience and want something different in their vape. Temperature protection is very effective in providing a vape with a consistent temperature...

    DNA40 vs SX350j

    The screen display and battery bar has absolutely nothing to do with temperature protection. Odd resistance readings and incorrectly being in power/temperature protection mode are issues commonly associated with wonky 510s and/or poor coil and/or mod builds. Trusting someone who used that build...

    DNA40 vs SX350j

    Garbage in, garbage out. A reviewer that does not fully grasp the concept that using a build like this to review temperature protection goes on my "totally ignore" list on the subject.

    Looking for a parallel regulated box mod.

    You might want to consider getting a mod that allows a fast battery changeout and carrying a spare battery with you. That will broaden your choices of mods considerably and allow you to use a smaller device. If you just want to carry a single battery as a spare to save pocket/purse space you...

    SXmini M Class (TEMP CONTROL)

    Legal niceties, good manners and psychic abilities to accurately intuit the intent of the sender aside, it is against ECF rules to post emails one receives from others. The most helpful place for YiHi's recommendations regarding vaping while charging via USB would be in their SX Mini M Class...

    SXmini M Class (TEMP CONTROL)

    It would be helpful for SX Mini owners if you would ask YiHi for permission for you to post their reply to you on the subject of vaping while charging via USB or, much better yet, ask them to include that info in their SX Mini FAQ.

    SXmini M Class (TEMP CONTROL)

    It would be very helpful for troubleshooting purposes to have temperature accuracy specs from YiHi for at least their recommended oHm build range. Specifics as to what they mean by "some unexpected behaviors" for 3+ oHm builds would also be useful to know. Since you have staff on the ground it...

    SXmini M Class (TEMP CONTROL)

    For the purposes of troubleshooting, at this point, the 10% margin of error is the most credible number we have although there is no way to know for an absolute certainty if it is spec for the final product. There is no way to know if YiHi decided that was what they wished to use in balancing...

    Crap luck with nickel/temp control

    You might want to contact your vendor if you have ruled out any iffy 510 connections or build issues. Poor soldering on TP mods, particularly the ground, seems to wreak total havoc with temperature protection.

    Greetings from a Newbie

    Welcome to ECF and congratulations on your first five days of not smoking! Wishing you continued success in your vaping journey. Nicotine in e-cigarettes is absorbed through the mucous membranes in your mouth and nose so you don't need to inhale deeply or at all if you are coughing. You also...

    SXmini M Class (TEMP CONTROL)

    [ Varitube spent quite a bit of time with YiHi at a Vegas trade show before the M class was released. They posted at that time that they thought the chip was accurate to within 10%. Later, around the time of release, I asked in the thread about temperature accuracy but my question was ignored.

    DNA40 vs SX350j

    Technonut posted information he received from Brandon at Evolv concerning board warranty replacement for an Evolv chip that is beyond the manufacturer's warranty. Evolv will honor the 1 year warranty but it must be removed from the device.

    DNA40 vs SX350j

    1.2 oHms is the borderline high end where I noticed a bit of temperature variation in my SX Mini depending on how wet/dry the coil is but I doubt most people would care. I get the type of consistent temperature I prefer on the SX Mini between .05–.08 oHms, 10–25 watts, 370°–430°. I haven't...

    Yihi SX350J Technology Discussion Thread

    If YiHi deliberately delayed shipment of a chip to P4U the chances of them telling anyone, including P4U, are close to zero. From what I've observed YiHi is very persnickety about the people with whom they share information and it is done without any hint of gossip. The email just looks to me...

    The Innokin iTaste VV V3 owners group

    Three out of my four are still going strong with one still usable but battery recycling heaven isn't far off. VV3/HH.357/Aurora BF on a lanyard remains my goto when I'm flitting around the house and yard.
