The evic features on-board charging! You can plug in to charge your battery instead of taking the battery out to charge on a separate charger.
The evic can also be programmed from your computer.
The 134 only goes up to 12.5 watts ; it starts out at 6.5 watts too, so limited in range; many others go from 3 to 15 watts.
The 134 also doesn't have vv as an option; it vw only.
The provari is 510 thread only; and it's vv only, no vw; but good warranty. And flat dc output.
If you use any of the computer software more than once for the evic I will be very shocked.. its cool and all, but the most you can do is program the home screen displays and mess with the same options you already have from the device itself.. it's kind of pointless and shouldn't be anything in the end to help you decide. (My two cents)
the new evic supreme will let you upload a picture to display on the screen.. another pointless option lol.. but at least it will go up to 30w for all the people who like that aspect.
