    Default Dial-A-Volt (DAV) review and technical info

    They arrived this afternoon (thank you Ms. Audrey), first one off the charger was the 900mah one so will be touching up on it technical wise first. These tests will be an on-going process, each battery size (650, 900, 1100, 1300mah) will be tested with the following cartos- DC- 1.5ohm, 2.0ohm, and 2.5ohm. SC- Wow and Cool carts because I don't have enough of the single coil tank cartos left to test them all. Luckily the wow and cool carts are close enough to them that differences between them will be minute at best.

    Will first get into the pv's themselves. A lot of people have asked why they got rid of the threads on the collar that the original non-vv egos had. Reason for this is simple, to prevent you using any other charge than the slim line on them. You can still use the mega cartos on them using a 510-808 and an 808-510 adapter with the DAV, but this means they no longer have to ship a slim line with every purchase. So keep in mind if you order one, you need to get a slim line charger. The look of these with a 3.5ml tank is perfect, and the cool carts and wow cartos don't look awkward at all on them either imo. To turn them on and off it uses the 5 click system. Will include the cut off time on each one as I review them but in the early tests (checked each one before charging them) it's between 10.5-13.5 seconds. To change the voltage you simply twist the dial on the bottom of the unit itself. There is a red line on it to mark what voltage you're running it at. The only marked units on the DAV itself are 3.3v, 3.8v, 4.3v, and 4.8v. The button is back lit by a green light on all four colors I have (green, blue, black, magenta) which leads me to believe that's only color it comes in. With that on to some technical info.

    The 900mah DAV-

    Will first touch up on the one issue this unit has. The voltage indicator dots above the dial aren't properly aligned on this unit, none of the other three have this issue, so don't think it's a wide spread. I can turn the red line past the 4.8v dot by about 1-1.5mm. It's not much but as the voltage test will show it does make a difference. Here are the voltage numbers off load with it-

    3.3v- 3.21v
    3.8v- 3.61v
    4.3v- 4.12v
    4.8v- 4.61v
    Dial turned as far right as it will go- 4.82v

    So on this one have to turn the dial slightly past it's mark to get the stated voltage. It's by no means a big issue. With dial based vv the numbers are more of guid, it's simply twist until you find your sweet spot with the juice/carto set up you're using.
    On to the on-load test. Will be doing the 1.5ohm dc carto first, since they're the ones that ship with the tank (have a feeling most people who buy a DAV will be using tanks on them as well anyways, so...). The other cartos will follow, these tests do take some time. Cut off for this one was 11.8 seconds.

    Voltage numbers at full charge with 1.5ohm dc-

    3.3- 3.16v
    3.8- 3.55v
    4.3- 3.91v
    4.8- 3.91v
    Dial turned all the way to the right- 3.91v

    The amp limit on the 900mah was 2.9a, so just like the omg handle and the omg vv you can't go past that limit. It will only give the maximum amount of voltage it can at 2.9a. So keep in mind with lower ohm cartos even if you set it 4.8v, it won't function at that. 3.91v on load though is higher than any other vv ego I've tested in the past, so again this is nothing to complain about.
    Here are the voltage numbers after 1 hour of heavy use (think 3-4 hours of use from a normal person, already have gone through a 3.5ml tank on it)-

    3.3- 3.16v
    3.8- 3.55v
    4.3- 3.78v
    4.8- 3.78v

    As the battery discharges the higher voltage will drop, but the same goes for every vv ego out there. The good news again is that a higher number than I've seen in the past with the same sized vv ego under the same conditions from a different company (3.73v being the old record recorded).

    Will be running this to the blink to see what voltage numbers I get, will post those asap.

    One other item to note on the DAV, the airflow. One of the biggest knocks I had on the original egos sold by V4L was the draw was tighter than my liking with anything but the mega cartos. This issue has been fixed on these. The draw is very similar to that of the king diamond and stealth (VT and non-VT) manuals.

    No problem Ms. Dedi.

    Final voltages from the DAV (charged it for ten minutes in the slim line after the blinks so I could do this)-

    3.3- 3.05v
    3.8- 3.11v
    4.3- 3.31v
    4.8- 3.31v

    All with the 1.5 ohm DC carto of course. Up next is the 1100mah

    DAV 1100mah-

    Unlike with the 900mah one, the dial and notches lined up perfectly with this one. This is the longest of the 4 DAV sizes, but same circumference as the 650 and 900 mah sizes. On to the technical side.

    Off load voltages-

    3.3v- 3.26v
    3.8v- 3.83v
    4.3v- 4.29v
    4.8v- 4.80v

    All numbers are well within range of the stated voltages off load, so no complaint there. For the on-load test, will be uoing the 1.5ohm dc carto for this test. Just as with the 900mah, the other cartos will follow. Cut off for this one was 12.4 seconds.

    Voltage numbers at full charge with 1.5ohm dc-

    3.3- 3.23v
    3.8- 3.76v
    4.3- 3.95v
    4.8- 3.95v

    The amp limit on this unit was 3.0a, as stated before can't go past that limit. It will only give the maximum amount of voltage it can at 3.0a.

    Here are the voltage numbers after 1 hour of heavy use (do mean heavy)-

    3.3- 3.21v
    3.8- 3.71v
    4.3- 3.82v
    4.8- 3.82v

    We see some drop, but with it still being able to hit 3.82v after a full tank worth's of juice has been used up is a good sign.

    Here are the voltage numbers after 2 hours of heavy use-

    3.3- 3.13v
    3.8- 3.34v
    4.3- 3.66v
    4.8- 3.66v

    Again nothing too surprising, still doing a good job of being over 3.6v (which is where most start to notice a serious vapor drop off and taste change with dual coils).

    About 40 minutes later the battery was dead, so just as with the 900mah battery put it on the charger for 10 minutes to give some final voltage numbers-

    3.3- 3.07v
    3.8- 3.13v
    4.3- 3.34v
    4.8- 3.34v

    Not too different from the 900mah, which wasn't a surprise.

    Up next will be the 650mah

    Thank you for the information and your review Mr. Morandir, sir.

    How does the size of the Medium 900 maH Dial-A-Volt compare with V4L EGO (also 900 maH)?

    I'm a little bummed that they removed the outer threads. I just bought some eGo cones that make the PV look nice when using with XL cartomizers (which I've been bringing to work). .I want to get some collars to see if they'll will work with the 3.5 mL tanks.

    It's same circumference, but it's about 10mm longer (will measure the exact length after I get home from work) Firestorm (sir or Ms.?).

    Thanks Mr. M! I love your technical breakdowns. How long on the charger do you see the 900maH take?

    12mm longer Firestorm.

    323 minutes BHam sir, roughly 5.4 hours.

    On to the 650 mah DAV-

    Just like with the 1100mah one, the dial aligned perfectly with the dots. This is the smallest of the DAV's, being a few millimeters shorter than the standard V4L ego.

    Off load voltages-

    3.3v- 3.23v
    3.8v- 3.77v
    4.3v- 4.25v
    4.8v- 4.81v

    Again all within range off load, again will be using the 1.5ohm dc cartos for on load testing this round. Cut off was 10.6 seconds on this one. On load voltages-

    3.3- 3.19v
    3.8- 3.61v
    4.3- 3.88v
    4.8- 3.88v

    The amp limit on this pv at full charge was 2.7a, which isn't surprising since it has the lowest mah of the 4 sizes.

    Here are the voltage numbers after 1 hour of heavy use (do mean heavy)-

    3.3- 3.16v
    3.8- 3.58v
    4.3- 3.77v
    4.8- 3.77v

    Ran it to the blink before I could do the next set of tests, so after a 10 minute recharge on the slim line ran the final voltage numbers-

    3.3- 3.04v
    3.8- 3.11v
    4.3- 3.28v
    4.8- 3.28v

    Not real surprising at all. This one will not last as long, or hold it's voltage as long as the other sizes, but it should be expected since it is the smallest of four. This one is closest in size to the original egos which will is it's biggest asset. Up next is the 1300mah with the 1.5ohm dc's.
