What is Ego?
There is a lot of confusion since the name Ego originated years ago by a popular vape pen model developed by Joyetech. At the time it made a difference with the cig-a-like type of e-cigarettes, so an Ego became a sort of a popular standard. Afterwards you could find Ego e-cigs of any brand you can imagine, and the term ego went beyond the original Joye Ego to become a standard, ultimately a standard type of thread.
You can use most Ego threaded batteries with any Ego threaded tank, they match. They can be screwed together.
At the end, what is important to know is that Ego is a type of thread that must be connected to its counterpart (male/female) Ego thread.
There is another common type of thread: the 510 thread. This is commonly used in bigger tanks and batteries, mods, etc. In the picture below, there is an Aerotank V2 and an Ipow 2 showing their 510 connection.
There is also an adaptor that allows an Ego tank to be connected to 510 threaded batteries or Mods like the one shown in the picture below.
There are many high quality vape pens, electronic cigarettes, vaporizers or whatever name (there are many) you like to use, with excellent performance that are Ego threaded. Of the most populars are the Kanger Mini Protank 2, Mini Protank 3, Kanger Aerotank Mini which are Stainless Steel made and can be disassembled and cleaned. There is also the popular Evod, originally made in plastic (an option I do not recommend as some flavors are known to degrade the plastic); there is also the newer Emow that comes in the Emow Starter Kit that is Ego threaded...and there are all kinds and brands of Ego tanks and batteries you can think of.
Ego threaded devices usually have a diameter of 14mm approximately (not the Emow which is 16.5mm). Most Ego threaded batteries also have a 510 thread inside the Ego thread, opening the possibility of using the battery with bigger tanks that are usually 510 threaded.
Using a 510 threaded tank with the internal 510 connection of an Ego battery might not be an optimal option in my opinion as it is not visually appealing to have a tank bigger in diameter than the battery, but from a functional point of view it works fine, most of the times.
There is the option of adding a "beauty ring" to make the transition in size visually smoother. Some tank kits come with a beauty ring like the Kanger Aerotank V2
Ego threaded batteries that also have a 510 connector (all Kangertech Ego batteries do), are charged using a charger that has a male 510 connector like the one you see in the picture.
Some Ego batteries have a USB port that can charge the battery or could also have a “passthrough” function. The passthrough function means that it will “pass” the electricity to the tank at the same time the battery is charging so you don’t have to wait for the battery to be fully charged to use it. An example of an Ego passthrough battery is the Evod USB.
You can find Ego batteries that have constant voltage (usually 3.7 V) like the Kanger Evod USB passthrough battery and also Ego batteries that have variable voltage like the Kangertech Ipow or the Evod Twist VV (variable voltage)
There are many options to mix and match, most work fine, other are not so good but still work. Make sure you are matching the thread and if you have any doubts on your choice send us an email, we will we gladly help you.
