Chain Vape with Sub-Ohm?

[seraphe]

Question is... Is there any way to chain vape with sub ohm setup? I'm a newbie on a 18350 mech mod and a Hobo rda. Built myself a dual-coil 0.5ohm and I really enjoy the vape production. Only problem is I can't vape any more than 4 long vape before the Hobo gets really warm. Reckon I should let it cool before another vape. Don't want to heat up the mod or battery.

Any tip how I can have more long vapes without this heating issue? A different dripper or a tank? Regulated mod? Higher resistance?

Still learning.

Btw I forgot to mention: my air holes are all wide open.

Heat transfer is fine as long as it's not super hot. Just drag it like as far apart in puffs as a smoke. My mods frequently get warm. If you want you can maybe buy a heat sink adapters to cut down on heat. A lot of sites have them.
But nothing to be worried about unless the actual battery itself is getting hot (not warm, hot)
Or the heat isn't coming from the battery.

First of all if the battery is from AW that is a 6 amp limit. I would stop using that immediately. Please purchase a mech that fits a 18650 battery that has a 20 amp rating or higher. Or get a regulated box mod. Be safe dude

Why?

Thanks for that warning, mate. I'm well aware of the continuous discharge rate. I'm using the AW IMR 800mah with advertised max CDR of 12A, and the purple Efest IMR 700mah with max CDR of 10.5A. Should be ok, right?

The heat is not from the battery.

Coz I'm residing in a place where vaping is banned so resources are scarce.

Don't get me wrong. Not going for smartass-points here. There are many ways to achieve 0.5 ohm. God is in the details, as they say.

You can probably achieve the same resistance with a single, thinner, shorter wire - meaning you would have to put a whole lot less heat into your atty to get the wire up to vaporizing temperatures. Any heat you put into your atty has to go somewhere. Ideally it's mostly spent on transforming liquids into vapor. Still, chain vaping at relatively high power in a tiny little dripper (or any atty) may prove difficult.

Either way, a decent way to get a (non-sciency) feel for how heat-efficient a build is, is simply to note how long it takes to bring up to temperature, and how long it keeps vaporizing liquids after you let go of the button. The more it lags behind, the more excess heat you shove into your atty. Point is to vaporize the most liquids per energy unit spent - not to heat the largest amount of coiling wire. The coil is not your friend. It's a necessary evil. Try avoiding it as much as you can - or as much of it as you can without ending up with a wire so thin it focuses heat too much.

Then again, there's always the Ultimate Solution to all things Vaping: Get another setup to share the load.

to chain vape properly you need at least 3 setups.... as the atty gets hot, you set it down and let it cool off, but use the next setup in line, once that one gets hot you move on to the 3rd setup. Once the 3rd one becomes too hot you go back to the first one ( which should be cool enuf to use again).... by having 3 setups you can increase your vaping time 3 fold since you have 3 batteries to carry the load...

Higher resistance with smaller wire. It will heat up faster and cool down faster giving off less waist heat.

I'm using 26 AWG kanthal. That should be small enough, right?

I use 28 AWG in parallel coils.

Two of these will be at 0.5 ohms, heat up and cool down fast because of the low mass.

Was actually asking about the Chain vaping part.

If you are comfortable with .5ohm, 28ga. would be better. It heats/cools faster and will not heat the quite as quickly. Your reserve juice will not boil up as fast due to excess lingering heat.

Also, make sure your Draw exceeds your button press. This gets all the Vapor out and draws cool air into the chamber reducing remaining heat.

Now this is what I need to learn about. Thanks mate

Like this

This was on a 3.25mm mandrill so it is only 8 wraps and 6mm wide.

Of course build to a safe resistance for your rig, the posts above are just examples.

What type of 18350 Battery are you Using?

Because at a Fresh charge of 4.2 Volts, you would be Asking the Battery to provided 8.4 Amps.

Amps = Volts / Ohms

And I am Not Aware of too many 18350 Batteries that would be Consider a Good Choice for that amount of Amps.

If you are going to go Mech Mod, I would Highly Suggest that you go with a 18650 Mech Mod. And use a Battery that has a Continuous Amp Rating of at least 25 Amps.

8.4a = 4.2v / .5ohm
7.2a - 3.6v / .5ohm

Why the 25a recommendation when Most Quality Batteries are rated @20a and fit the above need easily?

Made me break out my calculator

Because a Good 25A Battery costs about the Same as a Good 20A Battery.

And I have found that people tend to Lower their Ohms More than Raise their Ohms as they Get more into this.

for a 18350 battery i'd suggest a 1 ohm 28 gauge single coil
