What Are Low Resistance Atomizers and Cartomizers?

First off, what does “Low Resistance” mean?

Electrical resistance is a term used to describe how much opposition to current an object has and is measured in Ohms.  Basically, your atomizers have a certain resistance rating… I believe most normal 510 atomizers are between 2.5 to 2.8 ohms. You can buy low resistance atties and cartos with a rating of 1.5 to 2 ohms, and that is what makes it low resistance… it resists less current. They look exactly the same as normal atomizers but most of the time they will have the resistance labeled on them so you don’t confuse them with your normal atomizers.

Why use one?

I am glad you asked! When you use a low resistance atomizer, your atomizer coil draws more current through it, which makes it get even hotter than a regular one would. This produces more vapor, more quickly.  If you are looking to get more vapor regardless of the juice you are using, this is the way to go. Personally I believe these things really make somewhere in the ballpark of 15%-25% more vapor.  now, that is my opinion, and I don’t have any way to technically test that… At least not until I decide to start stealing from medical testing facilities.

Does it matter what type of e-cig you have?

Yes. Basically, I wouldn’t use this on any type of “mini” models (m401, 510, 801, 808, 901 etc.) or in other words any unit that looks like a cigarette or is in the general shape and size of one.

There are 4 potential cons about low resistance atomizers:

  • There is a chance that you can damage your battery (even on an eGo) because of the increase in current leaving the battery.
  • Even if you don’t damage your battery, you are going to drain it much faster than normal.
  • Low resistance atomizers are more likely to go bad faster than a normal atomizer. The increased heat and current causes more wear and tear.
  • The vapor is warmer (could be a bad or good thing depending on what you like).

If you are willing to ignore those reasons, then go for it. Both Gary and I use low resistance atomizers and cartomizers, but don’t come crying to me if you mess something up on your PV.

I use both LR (low resistance) cartomizers and atomizers on my eGo all the time, and have been for a long time. I have never experienced a problem (of course aside from decreased battery life) and I love them. I also love normal atties/cartos because I don’t have to worry about keeping them as wet, and a dry inhale isn’t as harsh as it is with a LR unit. LR atties and cartos work really well and I would recommend them to anyone who is looking for more vapor production.

    I still use the inexpensive pass-thru 510 but I change the usb cord to a usb computer quality cord (delicately cutting original cord 3 cm from e-cig and attaching the long quality usb cord with electrician’s tape & duct tape. I carry round an iPhone battery outside or plug into wall via usb outlet). My pass-thru lasts almost a year. My ego I use on the road or when out and about. I think the LR might work well as my long usb cord does offer some resistance on its own. I spend very little on equipment other than carbonisers and atomisers and occasional eGo battery & pass-thru. I spend well less than C$1 a day now on equipment and juice. I do like to add a little more nicotine to my 36 mg/g nicotine liquid.

    LR thats all I use at 3.7v vaping.. for my BUZZ variable pv I tend to like the standard 2.7 omh

      I was using only LR atties for a long time, but recently have been using standard resistance more and more to get the subtle flavors to come alive in some of my juices.
