True about the eVic being available, but it has several shortcomings that the CVI-2 completely addresses:
The eVic's switch has a 2.5 or 3 amp limit. The CVI-2's has a 5-amp limit.
In VW mode, the eVic can only reach 11 or 12 watts. The CVI-2 goes to 15 like most other VW devices.
I can't remember whether the eVic uses RMS mode, but the CVI-2 definitely does.
They both have pros and cons
I'd say if you won't go over the limitations of an eVic, the eVic is a better device. Better homescreen (with 1.2), smoother vape (no rattlesnake) at comparable wattages (according to the reviews the CVI uses the zmax/vamo chip, I have a zmax and an eVic) and of course in device charging.
The CVI is cheaper and goes bigger on power. The only caveat is from what I can tell you will need to stack batteries to get to 15 watts in most cases but obviously still much more than an eVic.
Both have a place and a target user.
