Thought you couldn't get a variable voltage tube mod complete with 2 batteries and a charger shipped to your front door for less than $50? Well, you were wrong. Unless, of course, shipments come to your back door. In that case you were right on a technicality. But you see where I'm going with this, right? I'm talking about the V-Unit from Vapow, the worst named electronic cigarette store on the web with the best price on version 1 lavatubes. You can check it out here on their website, and read my review below or skip straight to my video review at the bottom for those of you who don't like to read.

First off, here is what you get with this kit for $45.99.

1. 1 V-Unit device (the tube mod)
2. 1 small eGo style carrying case
3. 1 TrustFire dual bay charger
4. 5 standard sized 510 threaded cartomizers in your choice of flavor or blanks
5. 2 18650 Lithium Ion batteries.

That's a lot of product for your dollar, so let's start off with the accessories. The cartos are pretty standard, and I ordered mine with blanks so I cannot tell you anything about the quality of their liquid or flavors. The charger that came with the unit was a genuine TrustFire charger, and was white just like the one pictured on the site. That shouldn't be a surprise, but many times these companies don't update their pictures when they change the products in a kit so I was prepared to get a generic charger and was happy to see it was the real thing. The batteries were the same as pictured as well, and those are standard issue 2200 mah 18650's. Nothing fancy, but they power the device nicely and one battery lasted me all day plus a couple of hours on a single charge.

I used this device as a secondary unit for most of the 4 months I had it before giving it to my girlfriend, but I did use it exclusively for two weeks to get a good feel for it. Before I get into how the device performed, let me get into the amp limits on these mods the best way I know how.

For those who are not very familiar with how vaping works, let me put this in layman terms since that is what I am so my understanding of this is simplistic, so you should get this. Think light bulbs. If you put a 60 watt bulb in your bedside lamp, you will get a dim light that will be nice for lighting a small area. If, however, you put a 120 watt bulb in there you will light up the room. The atomizer in your e-cig is the same, just the opposite. Make sense? If you put a 3.2 ohm atomizer on your battery and vape, you will get a small amount of vapor and very light throat hit. Replace it with a 1.8 ohm atomizer, and it will burn hotter (like the brighter light) and give you more vapor and stronger throat hit. This is because the voltage of your device (most devices like the eGo, for example, are 3.7 volt) combined with the ohms of your atomizer produces a certain wattage at which you are vaping. A lower ohm means a shorter coil, which makes it burn hotter (or at a higher wattage).

This device allows you to change the voltage put out by the batteries. It offers a range of 3 to 6 volts. This means that the 3.2 ohm atomizer that was very unsatisfying on your eGo battery can now produce good vapor and throat hit because you can increase the voltage going to it and thus increase the watts that the device produces.

Now this leads to the amp limit. All of the above will work great on this device until you get to a dual coil cartomizer. A dual coil cartomizer has two atomizers in one cartridge. This causes it to produce more vapor and throat hit because both atomizers fire simultaneously when you hit the power button. However, because it is powering two atomizers at one time, it requires twice as much current from the battery. This device will not allow the batteries to operate at more than 2.5 amps. Thus, while it has no problem pushing a single coil 1.8 ohm cartomizer to 5 volts (which will be enough to burn your liquid) it will only allow enough amps to power a dual coil 1.8 ohm cartomizer up to around 3.5 volts. This means that with a dual coil cartomizer, this device will perform about the same or slightly better than your standard eGo battery.

Now given all of that, how does one tell if this is a good device for them? Simply put, if you like standard single coil cartomizers, ViVi Nova tanks, screw tanks, direct drip or rebuildable atomizers,or any other single coil device, then this unit will perform with the best of them.

If you like dual coil cartomizers, then this device probably is not for you. I have several mods, and I never use my DCT or dual coil cartomizers with this unit. Never. I do, however, use single coil cartomizers in a dual coil tank with this device, and it works great. But for my dual coil stuff, I always use my Zmax.

Bottom line, this is a entry level variable voltage mod. Now that you understand that, here is what I think about it for what it is.

1. Overall Quality

This is a very solid device. In the 4 months I used it, I experienced no problems with it. My girlfriend is using it now as her primary device, and it is still performing flawlessly. The button has a very nice click to it and fires every time it is pushed. The resolution on the screen is a bit low, but it is certainly readable.

2. Ease Of Use

This is where this device gets it's highest marks in my book. There are only four buttons, including the power button which is red. The red button also will allow you to see the remaining charge on your battery by pushing it 6 times in succession. There are two other small buttons, one with a plus sign and the other a minus. These raise or lower the voltage when pushed individually, and lock the device when pushed simultaneously and held for 3 seconds. The other larger button fires the atomizer.

This is one of the few VV mods without a complicated menu system for you to figure out. Within 5 minuted of playing with this device, you will be using it with no problem.

3 Safety

This device has the amp limit already mentioned. This will keep you from blowing out your atomizers on higher settings. It also has a vent cap in case of a battery malfunction and reverse battery protection in the event that you insert the battery the wrong way. It also has short circuit protection, preventing the device from firing in the event that you insert a defective atomizer, or one that is below 1 ohm.

The device also claims to shut off before over draining the battery, but that depends on what you consider over draining the battery. One night when I was tired I felt the vapor getting very weak. I checked the voltage and the battery was down to 3.2 volts. Do not depend on this feature, as the battery should be changed out before it reaches 3.4 volts for optimal battery life.

4. Fit and Finish

The device is a bit vanilla. It has a nice glossy black paint job, and the vapow logo gives it a nice contrast with the blue and white. That having been said, I would prefer it said "V-Unit" over "Vapow." The screen is red back-lit with black numbers. Nothing fancy, but still nice. It also has a small drip well around the 510 connection to catch small amounts of liquid that may leak when dripping or using a leaky tank or clearomizer. And speaking of tanks, this device looks sharp as hell with a nova or screw tank sitting on top of it.

Conclusion:

I highly recommend this device under the following circumstances.

1. If you are not married to dual coil cartomizers and you are wanting to see what variable voltage has to offer.
2. If you are looking for a budget friendly way to improve your vaping experience.
3. If you are wanting to test the VV waters before paying big bucks for something like the Provari.

I do not recommend this device under the following circumstances.

1. You are a dedicated user of all things dual coil.
2. Money is not an object, you just want the best thing going.

I hope this helps you out as you consider which device will work out best for you. I really liked this mod and my girlfriend still enjoys using it. I purchased it at full price from Vapow, and I am in no way associated with the company.
