OMG VV Technical Info (Part 2 of 2)

OMG VV in Blue

This is a guest post written by Morandir835, an e-cig enthusiast, admin on the Vapor4Life forum, and a regular on their ECF sub forum.

This article is the second part of “OMG VV Technical Info”. It gives some basic information about V4L’s newest mod – the OMG VV, as well as an introduction into variable voltage.

Testing

The three major factors to look for in a VV device are durability, accuracy, and amp limit. I use a self-powered multi-meter and a special adapter I’ve made specifically for testing. I do not use in-line voltage testers that some vendors sell. Those will tell you the voltage on a VV device to an extent, but an in-line tester derives power from the PV’s battery. This can lead to false results. Of course you can use one as a guide, but not as a perfectly reliable testing device.

The OMG VV with a full charge on it’s shipped battery was .1V higher than the voltage selected all across the board. This continued over the entire charge of the batt. On load was a different story (used a 3.3 ohm CoolCart for this test so all voltages would be available). With the supplied batt at full charge the voltage was +.1-.2V, after the batt hit 3.99V was -.1-.2V, and at 3.45V was -.3-.4V. I used a high drain IMR battery as well with testing. With the IMR voltage was +.2V at full charge, +/- .1V after the batt hit 3.99V, and -.2-.4V after the batt hit 3.45V. There was more accuracy with using the IMR batt than the supplied, but the IMR also has less mah (1100 vs 1600) so it won’t last as long. These numbers are well within range if not better than that of any other VV on the market, save one very high-end one.

Amperage Limit

Amerage limit controls how much voltage the OMG VV will actually put out. The higher the

amperage, the higher amount of voltage can be used on lower resistance cartos. Some variable voltage PV’s have an error code that tells you when you’ve gone past its limit, and you have to lower the voltage before you can vape. The OMG VV doesn’t tell you you’ve hit your limit, it just won’t supply any more voltage than the limit allows.

According to the manufacturer the limit on the OMGVV is 3.0a. Mine topped out at an in-range 2.8a. Again with the exception of one, variable voltage mods give you an amperage range cut off. 3 amp means it could be as low as 2.7, and as high as 3.3. A 3.3ohm CoolCart could use every voltage without issue, because even at 6V its only pulling 1.81a. No voltage limits were experienced using a 2.3ohm WOW carto either. Using a 2.0ohm dual coil tank on the OMG VV is a completely different story. No matter what I had it set to past 4.3V, it would only provide 4.32V (was pulling 2.77a at that voltage). With a 1.5ohm dual coil anything over 3.9V didn’t matter, 3.87V (pulling 2.76a) being it’s voltage limit. I got the same results using the IMR as the protected battery..

If your OMG VV stops working for any reason do a hard reset. Remove the head or the battery for more than 8 seconds. If it doesn’t resume function afterwards then contact Customer Service.

Watch for updates as my testing begins!
