    So I just got this used Czar mfg. Userper 18650 tube mech mod off of ebay. I'm pretty disappointed with its performance however. I've got a 0.41 ohm a1 twisted kanthal build on my drop solo rda right now, and running a Samsung 25r. But whenever I hit the mod, its just super weak. I do notice that the button has a bit of side to side play in it, and if i just push up on a corner it hits better. The mod is very clean, doesn't appear to be warped in any spots, good threads, button looks solid and doesn't stick. So i'm not sure if it's a connection issue or just me expecting way more than I should have. If anyone has any suggestions or ideas as to whats going on I would really appreciate it. Thanks much, Hunter.

    I would drop the ohms of the build to 0.25 ohms.
    That is plenty safe for a single 18650 mech.

    It will add around 1/3 more power (wattage) to the coils.

    You are drawing around 10 amps and putting out only 35 watts with the 0.41 ohm build.

    You could do either of these:

    Build at 0.25 ohms:
    You will be drawing around 15 amps and be putting out close to 60 watts at 0.25 ohms.

    Build at 0.2 ohms:
    You will be drawing around 19 amps and be putting out close to 75 watts at 0.2 ohms.

    The samsung 25r is a solid 22 amp cell so you are in the clear safety wise with both options.

    Okay, so I should just lower the resistance of the build and that pushes more amps and watts. Thanks for the info man! I'll throw a dual coil in there and try to get around 0.2-0.25 and see how she rips.

    0.25 might not be low enough for a dual coil build and I wouldn't go lower than 0.2 with a 25R.

    If I were you I'd go for a single coil build at around 0.21-0.23 ohms.

    Something along the lines of a tri-core fused clapton 26ga.

    Aside from the already mentioned drop in ohms. You might also consider a simpler wire coil with NI80. It will dramatically reduce the ramp time and improve the hit.

    Really? I'm not a complete noob but I thought you couldn't build ni80 on a mech mod. If you can then I'll definitely have to try, that sounds like a winner!

    Sure can. Its my preference. You cant use NI80 for TC mode, works awesome on a mech.

    I have to be really careful dry burning with NI80 because coil legs pop so easy compared to other wires.
    It's worth it though.:)

    22g is about perfect (IMO) and you really have to be trying to pop coils at that gauge or running super high and hot. 24+ is super easy to do it on.

    Forgot to mention that I mean Ni80 tri-cores :D

    Ni80 is my alltime-favorite, except for TC or if I need to reach a specific resistance on a specific build, I use nothing else.

    A word of warning when it comes to materials as you seem to be fairly new with mech mods.
    Never use stainless steel (SS316L and the like) or Ni200 on a mech.

    Those are TC compatible, which means they will change their resistance when heating up, which will of course mess with your vape. :)

    I would agree that I should know more, but I know what I can and can't build on my mech mod. I pretty much only stuck to kanthal because I knew it was safe, and I only stuck sub ohm builds on it. I did think Ni80 was just for TC but I almost only use my mech mod. I pretty much go by the feel of the lung and throat hit on judging if its too hot or too cool. i did just invest in the VandyVape 80w pulse squonker and a drop rda, but I still prefer my mechs. I figured using a good high drain 18650 and 0.5 and lower ohm build was all I really needed to know. The simplicity of mech mods it what keeps me going back to them.

    The links I posted should help. Moochs Blog will also help. For example the Samsung 25r will actually discharge upto 29A without heating past 100C. It will get hot, but will not vent. 20-23 up to 25A is fine, 29 is pushing it.

    In order to get a decent vape on a mech, you need to know how many watts your coil will generate and how many amps you have to draw to get it. You are totally right in only using high grade brand name batteries.
    The better you know the limits of your batteries and mod, and the more familiar you become, the better the vape you can get.

    IF you ever vent a battery, remember you have a couple seconds to get the battery out and get it into a cat box, sink, toilet, out onto the lawn, etc.. any more just chuck the mod... you can always get a new mod.
