I have the latest version of the E-MECH and I LOVE IT!
It has an output voltage range of 3.0 to 6.0 volts or 3.0 to 30.0 watts in 0.5 watt increments. And it will work with coils built between 0.5 to 5.0 ohms (though I have heard that it will work with coils down to 0.3 ohms). It has the standard 10 second cut off and offers short circuit protection and low battery indicator.
The V3 has addressed the issues with the previous versions. The Transformer stickers come in the box (which is very nice) and you can put them on the mod yourself if you really want to (I did not and I will give them to the first child I see that wants them) so I guess without the stickers you would just call it the E-MECH. Put on the stickers and you have the Transformers mod. They have gotten rid of the alarm clock function and the annoying beeps that everyone hated (its a totally silent device now) and I really like the fact that the display shows the time, day and date which really comes in handy.
This device shows the resistance in real time (I have seen the resistance value change without my finger on the power button as an older coils was getting ready to die) and the battery level just like your cell phone display does. Still has a puff counter but that does not detract from anything and can be easily ignored. If you move fast, after you are done with your most recent vape you can see the duration of your vape on the display screen before it returns to the main display The flashlight can be very handy and is very bright (I recently lost a black drip tip in a car with black carpet and floor mats and without the flashlight I would have never found the sucker). You can indeed charge your cell phone from it with the multifunction cord that comes with it. The updated version also has a larger base so you can stand it upright with toppers like the Kayfun and the like and it won't tip over easy. The high resolution OLED display is very easy to see even in bright sunlight while wearing sunglasses.
The touch screen is not a touch screen as you would think about it. The two buttons +/- are touch sensitive. Very sensitive so you need to lock the device once you have set it to the watts (or volts) you want. But the device is so easy to lock or unlock so for me it is a non issue. The power button is very nicely fitted and slightly recessed so it is not easy to accidently activate it while it is in your pocket. The power button has a quality feel to it and does not rattle or move around under your finger like the power button on so many other mods
And it is very, very well built. It has a very, very nice spring loaded center pin The internal charge works but the device is easy to open without tools (two swinging latches, one on either side of the back cover) so it is nothing to swap out the batteries and charge externally (with the 2 X 18650 2000mAh batteries I have in mine it takes 4.25 hours to charge using the built in charger). I normally vape it around 15.5 watts and I can get up to two days of use between charges. The batteries are connected in series with this device. The battery sled and terminals are very well constructed and marked +/-. While you can cram in button top batteries, it prefers flat top. And the back cover has a pad on the inside just to make sure the batteries do not rattle. But they fit so well they wouldn't rattle anyway.
I have accidently (I forgot to lock the device once before putting it in my shirt pocket where it fits along with my cell phone) vaped it at 26watts. Once. The vaper was incredibly warm warm (as it should be at that setting) but I did not get a burnt taste from the coils. Another plus for the USA made chip powering the device.
The device is very well constructed (out of aluminum I believe) and the finish does not pick up fingerprints and so far I have not been able to scratch it.
Here is a link to it on the Dovpo website..

And when I sat down to reply to this, I just meant to say heck yes, add it to your stock. As you can see I am a huge fan of this device. Vaping on mine right now!
