The eGo-V V3 Mega is a 1300mah VV/VW battery with an LCD screen and pass-through capabilities. It is the first eGo style battery with variable wattage. Similar in style to the V2 but with VW & a better LCD. It features short circuit, low voltage, & over-discharge protection, a 14-seconds safety cut-off, and a 5 Click On/Off function. The v3’s dimensions are 132mm by 17mm, so much thinner than most 1300mah batteries which are usually 22mm or greater. It is compatible with all eGo and 510 threaded atomizers/cartomizers/clearomizers. The pass-though sports a mini-usb connection on the bottom. I know some people are annoyed that it’s not micro-usb, but I have a multitude of devices with both, have many cables & chargers laying around, so for me it’s not a big deal. The LCD screen indicates power level, current wattage or voltage, lock state, and can also display the atomizer’s ohm rating. The wattage range is 3.0w-15.0w in 0.5w increments and voltage can go from 3.0v-6.0v in 0.1v increments. I picked mine up at sweet-vapes.com, in black, for around $32.
This is my first foray into VV/VW, and after a lot of online research, I settled on the eGo-V V3. For those new to VV/VW vaping (I’ll be writing a longer beginner’s guide later), here’s the gist: Most regular 510/ego batteries are regulated at 3.7 volts, this in conjunction with the atomizer’s ohm rating produce a given wattage (Watts=Volts2/Ohms). Wattage is how much power is coming to your coils. The more energy, the hotter your coils. This also means that if you take a standard battery, use an atomizer with a 1.6 ohm rating, you will get a hotter vape and different characteristics than if you used the same juice with a 2.2ohm atomizer.
Now first their were VV or variable voltage batteries, these would let you set the voltage within a given range, so in the example above, if you wanted to get the same characteristics on your 2.2ohm as on your 1.6ohm, you’d need to rase the voltage. You still had to do a bit of math, but at least it was possible. Now VW, or variable wattage, is a step above that. Instead of adjusting volts, you set the wattage you want produced, the device will read the resistance of the atomizer (ohms) and set the voltage automatically to the correct value. Now you can set your wattage and then swap out various ohm atomizers while still producing a similar heating profile.?
Anyway, back to the eGo-V V3. Pressing & holding the + button switches the device from VV to VW and back. Quick presses of the + or – buttons will increase or decrease the voltage/wattage depending on what is selected. The screen shows a V or W to let you know which mode you are in. Holding the – key down for a bit will display the ohm rating of the atomizer. When you plug in a new tank, this ohm value is also briefly displayed. Finally, holding down both buttons puts the device into lock mode, so that accidental hits of the button do not change your selected volts/watts. Pressing the buttons together again for 5 secs will unlock it. There is a small lock icon on the screen when the device is locked.
Build quality is nice, the black model has a coating that gives it a smooth rubbery feel, very comfortable. Power regulation seems to be very good all the way until the battery needs recharging. Speaking of a dead batter, the V3 is pass-through so you can plug it in to recharge but still continue to vape. I’ve really enjoyed this battery, varying the wattage, finding the right power level for various juices. Some e-Juices just work better at higher settings. I found Captivate’s The Good Sh*t to be much more flavorful at 10.5 watts. One great use of the ohm reader is to keep track on how your atomizer is doing. If after a while you see it’s ohms rising, you know it’s on it’s way out, or maybe needs a good cleaning. If the atomizer is dead you’ll get zero ohms.
My only complaint so far is that the power button gets stuck down sometimes. I’m hoping this will clear up after more use, but we’ll see. Also there is no end cap covering the bottom mini-usb port. True this means you can’t lose it, but I worry about junk ending inside the port from carrying it in my shirt pocket. At 1300mah this battery will last for a while. So in short, I love it. Setting the watts and letting the battery decide on the volts for whatever ohm atomizer I’m using is extremely cool. The slightly thicker body looks great with my larger clearos, like the Nautilus. This has become my regular vaping battery. At $32 the V3 is slightly more expensive than other standard eGos but the added VV/VW and ohm reader makes it worth it.eGo-V V3 Mega by SLB,
