I kind of doubt you actually hid the smoking because non-smokers can usually smell the cigarettes. I never realized how I smelled like burned tobacco until I quit. Now depending on what flavor you are vaping I am surprised the family isn't asking what smells so good and looking for the Banana Cream Pie or Strawberry Shortcake if you are into deserts!

I worked REALLY hard at hiding it. You have no idea the lengths I went to but no one ever mentioned it. And no one has mentioned anything about my flavors.

Hey everybody! I'm a brand new convert from smoking to vaping and enjoying the vape. I started with a Joyetech eGo - not enough punch. Then an ELeaf Istick Pico - LOVE this gadget but constantly refilling juice wasn't working for me. Moved up to Joyetech Unimax25 - LOVE this baby. It's my ADV. BUTTTTTT - I vape on the DL cuz my family doesn't like it so I needed something more stealthy to carry in my pocket. So I just ordered the new Smok QBox which is on preorder. I ordered it for less from a good shop on line but couldn't order new coils at the same time for it cuz it's a preorder. I like to have extra coils. I don't make my own coils or anything - I'm just getting into this so I bought some coils today from a local shop for my preorder Smok QBox. I bought 0.15 ohms cuz I'm looking for the throat hit but I'm also using 8mg nicotine and a 50/50 pg/vg. Should I have gone to a .25 coil instead? I know the .5 doesn't satisfy like a .25 that came oreinstalled on my PICO. If .25 would be better, please tell me why. Thanks so much! Glad to be part of the forum and so glad you guys are out there for us dumb noobs.
Welcome and glad you joined. Glad you found your happy place.

Its about ohms law.

The lowest resistance i would go on a 20 amp battery is .25 Ohm. There you are pulling 18 amps.

Trying to pull 30 amps out of a 20 amp battery is abusing The baytery.
How is a 50w mod going to draw more than 20amps with a .15ohm coil? 50w with a .15 ohm coil is 18amps according to Ohm's Law.

Shannon you should be fine with whatever coils you get even the .15ohm coils.

In this case it's Watts law for a regulated mod. W=A/V (less whatever you want for efficiency loss ~10%)

The average rating on a battery is 3.7V. So, the simplest solution here 50W/3.7=13.5A. The QBox uses an internal Lipo which makes it a bit harder as we don't know how low the battery drain will be before cutoff, nor do we don't know how many cells in the Lipo (yes, probably 1, but I'm generalizing) to be sure it's 3.7V (hard to imagine not at a 50W rating).

So, if this were an 18650 mod running at 50W for a 0.15 ohm coil it would be fine. In this case, as Smok knows what the battery is and we don't, and they rate the mod up to 50W with a 0.1 ohm coil, I think she'll be just fine too.

In using watts law you would have 2 unknowns to solve for. Voltage and amps as you don't know for sure either one. With ohm's law you have 2 known parts to the 3 part solution. You have resistance and power given in the equation. amps=sqrt (watts/ohms).
And yes the point being, given the specs given by the company that built the mod, the mod will be safe with a .15ohm coil head in the tank on the Qbox.

The thing is, the battery never "sees" the resistance of the coil on a regulated mod, the DC->DC converter does. 3.7V is nominal for the batteries we use. The wattage is known from what you select on the mod. The amps are then a function of those 2 values. Even if you drain a battery down to 3V for a soft cutoff (usually higher), it's still only 16.7A.

Don't get mad. I am agreeing with you. It's all good.

Oh no. Please don't take it the wrong way. I was just pointing out the difference between regulated and unregulated use. I've messed up on that in some threads and added untoward confusion to a simple problem. We both agree she's in great shape with that. Just clarifying the why.

Technically, this is one of the reasons built in Lipos are arguably safer than a replaceable battery, as the manufacturer should have done the math for you (hopefully). As long as you stay within their specs, you're supposed to be fine (maybe):D.
