Question: Towards the beginning of the review, you mentioned that the ProVari couldn't handle a certain amount of current draw (2.5 amps) and that the 306 you were using, you could really only set the voltage at 4.5v before getting the E1/E2 error? Or is that only if you're hitting it with a completely dry atty?
That is incorrect according to Ohm's Law. E=IxR Or, since we're finding current, (Amps), I=V/R And in your scenerio, V= 4.5v, R= 2.3ohms, therefore, I= ~1.96A --- Even if you ran it at 5v, you'd still be within the current shut off limit. 5v/2.3ohms = ~2.17A
I know it's nit-picking, but, it's a peeve of mine.
This is a nice showing of the ProVari, though, as you mention, there are already tons of videos on the device. However, I wish that you could have included the "extra" features that you mentioned as that would have been new and useful to a ProVari vet as myself
Either way, thanks for the showing.

I was speaking to the fact that that set up would give me an error when the atty started to get a tad dry. Becuase that atty can go from 2.1 to 2.3 ohms depending on how wet it is, juice adds resistance. The upgrades involve doing the same thing the old Provari did, just better. For example, the battery low indicator now works properly and doesn't start to flash early. Thanks for the tips.
I've tested several attys and cartos both soaking wet and dry and always get the same Ω reading ??
Not to mention that juice is actually mildly conductive and, in theory, will actually lower resistance, but not enough to matter.
Another nit-picker.

Here's the email i received by Provape in regard to ya'lls confusion on the topic.
Hi Rollin,
We haven't changed anything, so I think maybe someone is spreading incorrect
news if you heard this on the forum. They all have a limit of 2.5-2.7 amps
and the blue is definitely the latest version of everything.
The ProVari works with all types of atomizer and all ranges of resistance
but there are some conditions that can cause issues. We suggesting using
atomizers with a higher resistance. The reason is when a atomizer heats up
or runs dry the resistance drops very rapidly causing the ProVari to
shutdown with E1/E2 alerts. It's trying to protect itself and the atomizer
from cooking itself. As the resistance drops its going near a short
condition.
The reason low resistance atomizer were designed including the dual and
triple coil, was for devices that didn't have adjustable voltage and this
was a way to get more power say out of a set 3.7 volt device. By lowering
the resistance its increasing the wattage.
Since variable voltage devices hit the market and had the ability to raise
the voltage, low resistance attys are no longer the best thing to use on
these devices. By going with a higher resistance atty not only will you get
better battery life but it will open all the voltage options that you now
have access to and it gives the device some buffer room for the resistance
to drop when it's in use.
You can still get the same wattage and heat by raising the resistance and
raising the voltage as you would lowering the resistance and lowering the
voltage.
I would recommend trying some 2.8-3.2 ohm attys or cartos.
The top cap is stainless steel, so maybe a little stainless polish will take
care of that.
Hope you are enjoying the device.
Happy Holidays
Kindly,
David
