My wood swells.
Here's a great price on a starter kit.
Kanger E-VOD Starter kit, Kanger EVOD clearomizer, Kanger eVod Cartomizer
There is an overlap in words and meanings. Ego and evod can mean 2 different things.
Fist and most basic is what Izan posted
That style battery became known as an ego (even when made by others) but as noted, the connection threading is what makes it an ego (now).
Many battery devices use the ego threading.
Evod is actually both a battery and a clearomizer (atomizer). Usually people say it as evod kit, meaning both the battery and clearo, or they say evod battery, obviously meaning just the evod battery. Usually when people just say evod they mean the other picture from Izan, just eh clearo.
Bottom line, yes the evod (clearo) will work with your ego battery. Yes your ce4 type clearomizer (I'm guessing that is what you referred to) will work on an evod battery also.
When I'm watchin' my TV and a man comes on to tell me how white my shirts can be.
Well he can't be a man 'cause he doesn't vape the same apv's as me.
