VaporFi has a great selection of e-cigs that tailor to any level of vaping experience.  Their new high-end vaporizer, the VOX II MOD, is crafted with experienced vapers in mind.  The VOX II features an adjustable output power ranging from 7w-50w in .1w increments.  It also accepts atomizer resistance from .2 ohm – 3.0 ohms, meaning you can tailor the device to your unique vaping preferences.  The VOX II Mod Starter Kit comes with your choice of either the Bolt RDA, the Volt Hybrid Tank, or the Rebel Tank, depending on your vaping preference.

My first impression of the device was that it was very well made and had a great appearance for such a powerful mod.  It’s a finished silver color that in my opinion looks super attractive and sleek.  It’s got a good weight to it, but not too heavy where it’s a pain to carry around.  One thing that really stood out to me is the fact that it’s small enough to fit in your pocket.  Its dimensions are 94mm x 43mm x 24mm, making it a perfect size to take virtually anywhere.  It has a super bright OLED screen, which gives you a constantly-updating read of the output power in watts, the atomizer resistance in ohms, the output voltage, and the remaining battery life.  The two buttons on the front of the device really change the wattage quite fast, which I really liked because it can be a pain to wait forVox-50-II-Vapor-Fi-3 a slow meter to go from 7 to 50 watts.  It also has an auto Ohm resistance meter, meaning that it will find the ideal voltage depending on the current wattage for RBA and RDA atomizers.

This is definitely one of the stronger variable-voltage mods I’ve tried.  As far as specifics goes, it has an output voltage ranging from 3.0 volts to 8.5 volts.  The input voltage ranges from 3.2 volts to 4.2 volts.  The maximum output current is 22 Amps.  Another great feature is that is has 510 threading with a spring loaded pin, making it compatible with an endless number of tanks and atomizers.Vox-50-II-Vapor-Fi-4

The VOX II MOD Starter Kit comes with a high-capacity 35A 2500mah battery.   The VaporFi battery works perfectly with this device, and there are a bunch of protective features to ensure the utmost safety of its users.  The device has reverse battery protection, meaning that the battery can only be inserted one way, so you’ll never have to worry if the battery is upside-down or not.  The battery has a vented casing to prevent gasses and pressure from building up, ensuring your safety.  It also features output short-circuit protection, low voltage protection, low resistance protection, temperature protection, a device lock feature, and an input high voltage warning.  VaporFi really holds the safety of their customers in high regard, which is why I really love this device.  Another great feature with the VOX II MOD is that you can charge the battery with a USB cord, and it also acts as a pass thru, so you never have to stop vaping.  That was probably one of my favorite features of the device, since it can feel like forever having to take the batteries out and charge them with a separate charger, leaving your device dormant until the batteries fully charge.  With the VaporFi VOX II MOD, charging your battery will never be a problem.


Bolt RDA, Volt Hybrid Tank, Rebel Tank

As far as clouds go, this thing really delivers.  I decided to try the VaporFi Bolt RDA to use as my atomizer.  I chose to go with the Bolt RDA because it’s specifically made to work in conjunction with the VOX II, so I decided to give a try and see just how well these two products work together.  The Bolt really allows you to customize it any way you’d like, and it’s always fun to build your coils and wicks from scratch.  The Bolt RDA really gives you that hands-on feel that every serious vaper is looking for.  I was very happy with my purchase.  Let me start by saying, they really give you a lot of great stuff with the Bolt RDA.  They give you the 22mm Bolt RDA, 4 additional o-rings, 10’ 30g Kanthal wire, 1 screwdriver, 3 screws, and 1 drip tip.  I love that they give you a bunch of extra o-rings, because in my other vaporizers I feel like these can sometimes wear out very quickly.  I’ve been using the VaporFi o-rings and they still look great after a few weeks of use.  The Bolt RDA also features a copper 510 connector and has the ability to adjust the airflow depending on your preferences and set-up.  The Bolt is designed to be compatible with a dual-coil set-up, allowing you to sub-ohm for your vaping pleasure.Vox-50-II-Vapor-Fi-2

Initially, I did just a single-coil set-up to see what kind of vapor it would produce with just the single coil.  With the single-coil, the resistance measured at 1.5 ohms.  It produced a lot of vapor, and I was impressed, but I knew this thing could do a lot better than that.  I decided to add in another coil to see how well it could truly perform.  If you know what you’re doing, the dual-coil setup is really the way to go.  I prefer to vape with a sub-ohm setup, so I wrapped my coils to perform at a 0.5 ohm resistance.  Regardless of whether you set the VOX II to 7 watts or 50 watts, you are going to get a smooth, clean hit and lots of vapor.  At first I wasn’t quite sure what to expect from this device, but it really blew me out of the water.  The clouds of vapor produced from the dual-coil setup were massive! And I never coughed once while using it.  It also preserves the flavor of the juice you’re using, so you never have to worry about lackluster hits.  I actually had to reduce the amount of nicotine in my juice because I was using it so much throughout the day!  This will definitely be my go-to vaporizer from now on.

The Volt Hybrid Tank is the second option of tanks/atomizers that are available with the VOX II MOD Starter Kit.  It’s referred to as a hybrid because it allows you to choose between pre-made organic cotton atomizers, or a rebuildable deck with pre-made RBA coils.  The Volt Tank has features such as adjustable airflow, materials needed to create your own build, a spare Pyrex glass, 2 pre-built coils, and the ability to use both low and sub-ohm atomizers.  The third tank option is the Rebel Tank, which is a dual coil tank.  This tank features adjustable airflow and juiceflow, giving you endless options so you can enjoy your favorite e-liquids exactly how you like them.

Overall, I was extremely impressed with the VOX II MOD Starter Kit and the Bolt RDA.  Although the price for these items is on the higher end, the quality and performance really cannot be matched.  VaporFi’s engineers really went all-out on this device, and the workmanship and safety considerations are worth every penny.  Another great feature is that you receive a 6 month warranty for your device as well as customer support, which is something you don’t get with most mods straight from China.  If you want a customizable device that will deliver huge clouds of vapor, while making the user feel completely safe while using it, VaporFi’s VOX II MOD and Bolt RDA is truly the way to go.

    I decided to try out the VOX50 because I wanted something more advanced that will let me get big clouds like a lot of other people I’ve seen with these type of devices. I was so impressed! It’s also very easy to use which I like since prior to buying this I had never dealt with an advanced device like this,

    I was drawn to VaporFi because of their customizable e-liquid selection. I decided on the VOX50 because it looked like a great device that was also easy to use. I was super happy with my purchase. The e-liquids taste exactly how I wanted them to, and the device gives me so much vapor and it’s so easy to use and re-fill. I love this thing!

    Although this thing is pretty pricey, I was very impressed with how much vapor this thing gives off. I also like that I can choose between thousands of flavors on the VaporFi website. Would recommend.
