The Vstar variable voltage mod looks exactly like the Joyetech Evic. Looking at the specs it looks like this device has a lot of the same features as the Evic so I would say it’s safe to call this an Evic clone. Take note that the Vstar doesn’t have a variable wattage setting but it will fire from 3 volts up to 6 volts in 0.1 volt increments.

If you like the style of the Evic but aren’t happy with the price then the Vstar variable voltage mod might be worth looking at.
