A few weeks ago Vapor4Life launched another new product, the V4L Dial-A-Volt (DAV  for short). I've tested these for the past few weeks,  and so far have been very happy with the findings.  The tests  have been an ongoing  process, with  each battery size (650, 900, 1100, 1300mAh) being  monitored with the following cartomizers:
  • Dual coil cartos:
    • 1.5ohm
    • 2.0ohm
    • 2.5ohm
  • Single coil cartos:
    • WOW carts
    • CoolCarts
I decided against testing the DAV with a 2.0ohm or 3.0ohm single coil carto for a couple of reasons. 1) I  don't have enough of the single coil tank cartos left to test them all, and 2) the WOW and CoolCarts are close enough to them that differences between them will be a minute at best. Compatibility I won't go too much into the technical numbers now, but when the tests are finished, I will include the link to the thread on the V4L  forum with all the data. The look of these with a 3.5ml tank is perfect, and the CoolCarts and WOW cartos don't look out-of-place either in my opinion. You can use EGO mega cartos on the DAV as long as a 510-808 and an 808-510 adapter are screwed on it. Instructions The DAV is turned on and off with a 5 click system.  The cut-off time for these are between 10.5-13.5 seconds, much like that of the Original Vapor King Diamond and Stealth manual batteries. To change the voltage you simply twist the dial on the bottom of the unit itself. There is a red line on the dial to indicate what voltage you're running at to a point.  There are four marked units on the DAV  itself-  3.3V, 3.8V, 4.3V, and 4.8V. So if you want to set it to exactly 4.6V you'll need a multimeter for it. In all honesty though because of the ease in which you can change the voltage, the numbers don't matter as much as just finding the spot that suits you best.  The button is back-lit by a green LED as well, indicating if it's on and when the battery is low.
