When first exposed to the world of electronic cigarettes, it’s easy to become overwhelmed. Smokers who, until now, only had to choose what brand they smoked are confronted with thousands of variations of electronic cigarettes.
Kicking the smoking habit and switching to vaping is worth the learning curve. This guide will help you understand one of the most common issues new electronic cigarette users face: knowing the different thread types electronic cigarettes use.

This device allows you to connect with either eGo (the larger side) or 510 (the smaller side) threading.
First off, threading is simply what allows your atomizer to screw onto your battery. While some manufacturers use proprietary or specialty threading, the two most common by far are 510 and eGo threading. Any eGo threaded will fit on any eGo threaded battery, and likewise for batteries and atomizers with 510 threading. Understanding the difference between these two thread types will prepare you for the vast majority of e-cigs on the market.
Most cartomizers and clearomizers tend to have eGo threading, while most tanks and drippers tend to feature 510 threading, although that is not always the case. One of the main reasons for this is that clearomizers are designed with the eGo style battery in mind, while many Advanced Personal Vaping (APV) users prefer to use tanks and drippers. If by chance you find that your cartomizers or tanks are not compatible with a mod you’ve purchased, there is no need to throw them out. Many e-cig vendors make adaptors for almost all commonly used thread types.
eGo Threading
EGo threading was originally designed to allow manufacturers to make cones and cartomizers that would hide the threading and make e-cigarettes more visually appealing. The popular Joytech and eGo style batteries all feature both 510 and eGo threading. The inner thread of eGo style batteries is a 510 thread, and the outside thread is an eGo thread. Because of this, eGo batteries can accept cartomizers or tanks that feature both eGo and 510 threads.
Some of the most popular mods that utilize eGo threading include:
- Kanger EVOD-C, eSmart, and EVOD VV Twist
- Oakley FireFly eGo Gemini
- VISION spinner eGo VV
- Joytech eGo-C, eGo-T, eGo-CC, eCab, and eVic
- Innokin iTaste MVP,
510 Threading
510 threading became extremely popular with the rise of variable voltage and mechanical mods. By far, it is the most common thread type for APV devices. APVs are often called “big battery mods” because they tend to use replaceable rechargeable batteries, as opposed to eGo mods, which use a fixed, internal battery. While most eGo batteries also feature 510 threading, the same is not true of most 510 threaded mods. Since 510 is the most popular APV thread type, most APVs only feature 510 threading, but there are a number of exceptions.
Some of the most popular mods using 510 threading include:
- ZMax and Zmax mini
- iTaste SVD, VV
- SMOKtech SiD*
- Provari
- VAMO V3*
- Kamry K200
- Sigelei mechanical mods
- Kamry mechanical mods
- Most mechanical mods
- Joytech eVic*
*Indicates APV mods which will also accept eGo threading.
Other Threading
While eGo and 510 threads are the most commonly used thread types for electronic cigarettes, some other thread types bear mention. While less common, the 801, 901, and 4081 thread types are found on many “cig-a-like” form-factor e-cigs. For example, Njoy, one of the first makers of disposable electronic cigarettes, is known for using 801 threads. IT si important to find out which thread type your device ie equipped with before you make a purachse. This will let you kno if it is compatible with pieces that you already own, and will be crucial when upgrading tanks in the future.
