eCig Mod Wire – What Size to Use In A Mod

I see this question all of the time.  What wire gauge or size should I use in an eCig mod?  I’ve seen people use wire that could rival your household electric wires in size just for an eCig mod.  I’ll let you in on a little secret right now.

If you have ever taken apart a regular ecig battery, the wires going to the atomizer connector are small.  Very small.  So small that most people wouldn’t even dream of using wire that small becuase it would be so hard to work with.  The wires are so small that they break very easily also.

So what does this mean for my own mod?  What size should I use?  If you are building a eCig box mod like the PUCK, the wire that already comes with the battery boxes are way more than fine for the job.  You do not need very large wire at all and the wires in the battery boxes are small but not even half as small as the wires in a normal eCig battery.

Normal hookup wire would suit any eCig mod perfectly that you can get at any Radio Shack.  Smaller gauge speaker wire would even work well (not the larger speaker wire since it is too large) and is what I use most of the time.  I also like to use the wires that come in the microphone cable Radio Shack sells.

One thing to remember and a rule I would lay down right now to you is use stranded wire, not solid.  Solid wire has a tendency to break easy.  Move it a few times and it will snap a lot of times.  Stranded wire is flexible and will last the lifetime of your eCig mod.

So to sum this up, you can use just about any size of wire you have available for your ecig mod.  I prefer smaller stranded speaker wire but it’s up to you.  since eCig batteries use almost micro wire, anything you use will most likely be bigger and can carry more current than a regular eCig battery wire could.  So use anything you have available, as long as it is not solid wire. Use stranded and you will be happier with your new eCig mod.

    I’m just now getting into (the idea) of making box mods. I’ve been looking over your site carefully. Regarding wire gauge. As I’m trying to limit the money on spend on vaping products (spending a lot lately as I’m still 2 moths into the vaping world) I would like to use what ever wire I have around the house. Is it ok to use different gauge wires to complete my set up. I would assume so since, as you mentioned above, the wires that came with my prewired 510 connector are really thin and such I would assume I wouldn’t be expected to use similarly thin wire. I just want to make sure before I go soldering all the parts together only to find out later on that the unit doesn’t work as well as it did when I first breadboarded it….. Thank You and thank you for providing all the great information on this site.

      You can use any wire you have without any problems. I mainly just use the wrie that comes attached to the battery boxes since they leads are always way longer than what you need and you will have extra wire from them.

    I’m looking into making a dual 18650 box mod just a simple one with basically just a button and a ego connection do you have a info guide on it I don’t want an led or anything in it but I did see a button with a built in led at radio shack who’ll that work

      When you say dual, do you mean you want 3.7 volts (just longer lasting battery power) or 7.4 volts (too much for a normal tank or atty).

      I would assume you want longer battery life which means 3.7 volts. That means you want the batteries in parallel. That would be both batteries have the pluses tied together and the minus ends tied together.

      Basically once you have that, you have a set of parallel batteries (double the life basically). Run a wire from the negative of these batteries to the outter casing of the ego connector. From the plus side of you batteries, run a wire to one leg of your push button switch. From the other leg of the push button switch, run a wire to the center conductor of your ego connector.

      That is basically it if you are not using an LED. For an led you would just solder a 470 ohm resister to the positive leg of the led. The other lead of the resistor would connect to the wire going to the center of the ego connector. The negative lead of the LED would go to the negative wires of your batteries.

      You could refer one of my articles here… http://puckecig.com/2013/02/build-your-own-mod-any-way-you-like/

      The batteries in that article are wired in series. You will just want to follow my above instructions for the battery hookup to be in parallel. That would be the only difference (all minus sides tied together and all plus sides tied together).

      Let me know if you need any more info.

    Im looking to build a mod using an 18650 vtc5 battery. I want to be able to sub ohm on my mod and want to ensure the wires can handle the higher than normal current. Can you give me any advice on reading on this?
