Advantages\Disadvantages of single tube vs. multiple tube 18650 mods

[SharkByte]

Question for all you vaping vets out there. I've been looking at mechanical mods for the last month or so, trying to decide what my next toy should be, and I've noticed that the majority of mods come in a multi-tube configuration that allows you to change the length of the mod based on the battery you want to use. Very few, comparitively, come as a single 18650 tube configuration. I don't anticipate that I would be using anything other than an 18650 version of the mod, although I'm also considering 26650 style mods, but let's just stick with 18650 for the sake of this discussion. I've pretty much decided that I want a copper mod, due to the voltage drop issues with other types, but I wonder if there are any other considerations\issues when it comes to multi-tube vs. single tube style mods. It seems to me that with more pieces in the mix, you would have more potential for voltage drop unless you were to take the tube(s) apart regularly and clean the threads. This could also introduce the possibility of mucking up the threads over time.

I'm curious to hear from both sides of the fence on this one. Those who prefer single tube and those who prefer multi-tube, but not necessarily about the advantages of being able to use different battery configurations. That's not my real concern. I'm really only interested in voltage drop, compatibility, maintenance, and availability types of responses, and of course, anything else I may not have considered. Who knows, maybe someone will convince me that a multi-tube mod would be the better option. Thanks in advance.

You really should clean your device periodically, and lube the threads with a good quality conductive paste. I use NoAlox. Even a fixed tube mod will have threads, and yes, any threaded connection is also an electrical connection and a potential voltage drop. Hence the conductive grease. Which also decreases wear on the threads.

The other issues would just depend on the specific mech.

I have 4 mechs. Thee are telescoping. I have a #19 ( don't get that), Magneto (good mod), K101 ( not great), Copper hades (my fave. Telesoping mods have their advantages in my book but you don't find to many hybrid kits for them. The Hades is great. If you get that get the 18650 battery adapter for it and you can use 18650s or 26650s in it. That is my best mod. I find that i have to clean my telescoping more often because of normal dirt and juice leaks gunking up the threads. Had that also happen to my Zmax was getting a hot spot at the threads of the mod. Lots of good copper ones out there. If i were to replace my #19 and k101 i would get a copper Nemesis or Stingray with copper contacts if possible. The Nemesis has more hybrid kits for it than any other. My best right now is the Hades. The Magneto is in second place and the #19 is in last because the damn thing still misfires even after doing all the upgrades. The k101 works great but has way to much Resistance.

...anything else I may not have considered.

I have a Nemi clone which has multi tubes but I always run it in 18650 mode. If I'm out and about and need to go small I use a REO Mini but that's just me. The issues for me which you may also consider is:

1. Can you reliably stand the mod up without it firing? All my futzing, extra magnets, longer contacts and it's still not reliable all the time. Switch toppers from one type of RDA to a RBA and I need to futz again. I've seen mechanical mods with deeply recessed fire buttons on the bottom in both the fire position and the lock position. These would work all the time. Something to consider.

2. I chase flavor and you could call me a juice snob and I'm not offended. /lol I have to be able to dial in the voltage/wattage for a given juice and insure that it stays constant throughout the life of the bat. I CAN taste the difference as the voltage drops in the bat. You can't do that with a mechanical since it's a non regulated device. Enter a gizmo called a Evolv Kick 2 which you install in the tube and it regulates your desired wattage so it's the same for the life of the bat. Not cheap and not for everyone but maybe something to consider since not all mechanical tubes are the proper size for a kick 2.

HTH

Great points, SeniorBoy. Although there are side button mechs that get around point #1 that are an option, both bottom and top button models around.

Like you, I prefer the adjustability of VV/VW mods, and have a Kick for my mech. But they're really for my vapocalypse box. But they do work well for VW (and there's now a VV model as well), giving you the flexibility of an adjustable device and some extra protections for the battery and you. But also the limitations in max current of regulated mods
