My V8 is here!!!!!! Initial thoughts? I love it!!! Its the perfect size and I love the color. I cheated and put a pair of batteries in it because I just couldnt wait, I only took a few tokes becuz I want my batteries to last but WOW, this thing is amazing even @ 3 volts!!!! Thank you so much Eric, I couldn't be happier!!!! Today feels like Christmas in June! Lol

Here is my new stealth E-Power. I cut the tube down to accept a 14430 battery.

Only mistake I made is the wife was standing next to me as I opened the package. Not only did she confiscate my gold drip tip, of course now she wants a mini E-Power too.:facepalm: Should have known to order two:)

Here it is next to my 14650 LG mod. Not nearly as handsome, but it's very pocket friendly.

BTW Eric. I owe you for a switch. My tube came with a LR blue LED switch!

I thought you had said you had a bad one so I replaced it, assumed it was mine :)
No need for anything, hope it work for you :)

I received my V8 today, and it is a powerhouse.

I've been using a CE4+ and an E1 Revive V2 on the provari at 4.0 Volts. Set the V8 on 4.0 Volts and promptly blew the coils on those two. I'm thinking that the V8 is putting out more than what is indicated. Dropped it down to 3.0 Volts, put a new CE4+ on it and all is well. Tons of vapor and great taste. Also changed out the innards in the E1, and it is doing great on the V8.

I have an oscilloscope (DSO Nano v2) heading this way and will take a look at the V8 output to determine the peak and average voltages at the various settings. I'll post the results here.

Hits like a truck doesn't it!? :) I received mine this afternoon and ive been in a really big cloud ever since! Lol

It sure does. Just start out with a low voltage, move up slowly, and stop when you're comfortable with the vapor.

I'm running mine on 3.0 Volts on devices that I run at 4.0 Volts on my Provari.

Nice!! Does the bottom come off and you then cut the tube to length and put the end cap back on? What kind of battery life do you get from a 14430? They are 650mah, right? So I assume about 6 hours roughly? I might have to get an extra tube and battery to try this out. Would be nice to have a stealth option:)

I find myself not taking the Twist above 3.7 either. It seems that my clearos, and my juices of choice, prefer the lower voltage for flavor. I don't see a big increase in vapor pushing it to 4.0 volts, and it kind of starts tasting burnt. I do love the VV now, I am going to leave my e-power as a back up from now on. Last night, I almost got through the entire day on one 900 mah. I started to vape on it at 8:30am and it died around 9pm. That's pretty good:)

I see one more Twist in my near future.

P.S. I love the CE4 V1 on the Twist. It looks amazing and I get clouds of vapor!

This is my first VV and the highest ive gone is 3.4!!

That is the same Oscilloscope I have. Make sure to get the latest BenF loaded on it. If you need any help getting it updated, give me a shout out on Skype. I used the dfu-util on my Mac.

If you are looking for the peak and average, I have some in my review of the V8. They may help until the DSO Nano V2 arrives. Obviously, I could only focus on a set voltage or two during the review, so a nice listing of each is really needed.

The reason the V8 blew your coils, is because it isn't a constant voltage, like your ProVari. The V8 uses Pulse Width Modulation, which means it hits the coils at about 7.2V (sometimes it peaks at 7.4V) pulses according to the DSO Nano. Even though the averages under load are lower than their intended voltage, they still produce more wattage. Here is why...

When you calculate wattage (ohms law) on a constant voltage device, you calculate the voltage squared, and divide by the ohms of resistance. This is basic ohms laws, as I know you are aware.

When you calculate wattage for a PWM device, you calculate the peak voltage squared, divide by the ohms of resistance, and then divide by the duty (percentage of pulse).

Now, taking into consideration that the PWM device is only averaging about 3.2V average (40% duty), when set to 4V, we are going to give some examples using 4V setting, with a 2 ohm cartomizer:

Constant Voltage: 4V squared = 16. Divided by 2 ohms = 8Watts
PWM: 7.2V squared = 51.84. Divided by 2 ohms = 25.92Watts. 25.92Watts divided by 40% = 10.37Watts!

Roughly, the PWM device is 25% more powerful than the constant voltage device, in this example, at the same setting. Now, these examples came from the V8. :) But, keep in mind that I haven't had my morning coffee, so my calculations may be off a little. Plus, the V8 does peak higher at times, so the duty would be larger at times.

Yep, that explains pretty well why people are having to set the V8 at such a low voltage. Since most clearos are designed to work on a normal eGo, such a drastic jump, without some poly filler to keep the coil nice and saturated at all times, will make it pop. IMHO. I think the V8 is an amazing machine for the price, it cannot be beat, but it looks to be a little overkill if all you use is CEs. There might be an exception on certain clearos that are 2.8ohm and above. Currently, all my clearos are between 2.0 and 2.6.

I am still considering purchasing the V8, however, as I do still have my tanks that I didn't like so much on my e-power. I need to bust them out this week and give them a go at different voltages. Maybe I will like them again? Also, to have more than 900mah in battery power would be very nice;)

Question to all: Does anyone vape a CE2/3/4 past 4.2 volts? Actually, 4 volts is already over my limit. I find it very harsh and unbearable.
