Today, I will be reviewing the VaporFi Vox II Mod.  The Vox II is the improved upon version of the original Vox 50 Mod.  For those who aren’t aware of the company, VaporFi is an online and offline retailer and distributor of electronic cigarettes and a manufacturer of Premium USA Made E-Liquid. VaporFi also happens to be a wholly owned subsidiary of International Vapor Group, Inc., which is a rather large and well-known company within the electronic cigarette industry.  Get comfortable, take a seat and enjoy reading or watching this VaporFi Vox II Mod Review.


Appearance / Packaging: The VaporFi Vox II Mod looks aesthetically pleasing.  The device is rather small, sized perfectly to be pocket friendly, yet large enough to fit comfortably in the hand.  It stands just 94mm tall, 43mm wide and just 24mm in-depth.  Since the original Vox 50 Mod had a lot of similarities to other devices, the VaporFi Team did an outstanding job with its appearance, as the Vox II is 100% designed and crafted by the VaporFi Team.  It was obvious that they were aware of the past similarities, so they’ve made sure to boast on the description page for the Vox II that “this unique device will not be found anywhere else.”

The Vox II’s overall appearance is a box mod, but one side is rounded to shape out the 18650 battery that it holds, but also to give the device a comfortable feel to the hand.  The top of the device has a chrome plate, which looks to be made of zinc alloy.  This plate holds the 510 connection that surrounds a spring-loaded center pin.  The bottom plate at the bottom of the device looks to be made of the same material.  On one side it has a micro-USB port for charging and the opposite side has a round cap that unscrews to access the battery compartment.  The VaporFi Vox II has an anodized silver coating over its lightweight aluminum body.  Covering the length of the device is the VaporFi logo and to the side of it says “Vox II”.  The opposite side of the device is blank.  The flat side of the device holds the fire button, OLED screen, as well as the wattage up and down buttons.  The buttons seem to be made of a thin metal, but have a little rattle in them, which isn’t that big of a deal.  The screen is nice and bright, easy to read and displays the battery percentage remaining, the resistance, volts and current wattage.

Packaging: If there’s one thing I must say about VaporFi, it’s that they really go above and beyond with their packaging and branding for their products.  The Vox II comes in a nice VaporFi themed box, sporting the white, gray and green colors.  The top of the box has the VaporFi logo, below is a picture of the Vox II Mod, and below that reads “Vox II” and “50 Watt Vaporizer”.  The rest of the boxes sides are plastered with the themed colors and branding.  The back of the box has more branding at the top, what comes in the box, the URL to VaporFi and below that are warnings.

Inside of the box you’re first confronted with the VaporFi Vox II Mod, below that is a User Manual, and at the bottom of the box sits a micro-USB charging cord and a small box holding a high-capacity 35A 2500mAh battery that has been branded with the VaporFi green color and logo.  I enjoy the fact that they’ve included a battery, especially a 35A battery, but I do not enjoy using a battery that has been re-wrapped.  If I’m going to use a battery, I want to know the original manufacturer of the battery.  I understand that VaporFi likes re-branding any product they retail as their own, but I feel re-wrapping something so serious as a battery is not a great way to improve their brand.

Features: Let’s first start with the Vox II’s hardware features:  The device does have a 510 spring-loaded center pin, so attaching any atomizer will come without hassle.  The buttons are very clicky and though I’m not necessarily a fan of how they look, I do enjoy the feel of them.  The device feels thin, but the plates at the top and bottom are hard and durable, so that definitely improves the device’s durability and it plays well with the overall appearance of the Vox II.  I don’t like that the micro-USB port has been placed at the bottom of the device, but it’s also something I’ve become used to since most other devices have micro-USB ports placed in the same area.  I like that the battery cap sits flush at the bottom, but I don’t like how it was designed because it’s aggravating screwing down the cap when inserting a battery.

The VaporFi Vox II can run up to 50 watts, can fire down to 0.2Ω and is powered by a Yihi SX330V2 Chip.  One feature that I’m not too comfortable with, but has been seen in devices more and more here recently is the “Auto Ohm Resistance Meter” feature, which finds an ideal voltage for your atomizer.  That being said, this device will step down in power depending on the battery life that you have left and the atomizers resistance. You’ll see  “CHECK BAT” come up on the screen.  Again, not a great feature, but it is a feature that is being used to add another level of safety to these devices.  Another notable feature available with the Box II is the 5 memory settings it has that will allow you to store a certain wattage number per slot.  That being said, you can input your most used wattage number in 5 slots and easily reach them by waking up the device and pressing the wattage up button.  To not jump into your settings, waking up the device pressing the wattage down button will allow you to adjust the wattage as you wish.

The Vox II also has other included features, which are all devoted to safety for the device.  These features include: Output Short-Circuit Protection, Reverse Battery Protection, Low Voltage Protection, Device Lock Feature, Low Resistance Protection, Input High Voltage Warning, Temperature Protection and has a Vented Battery Casing.


  • Adjustable Output Power from 7 w – 50 w (in 0.1 w increments)
  • Accepts Atomizer Resistance from 0.2 ohm (sub) – 3.0 ohm
  • Output Voltage Range: 3.0 v – 8.5 v
  • Input Voltage: 3.2 v – 4.2 v
  • Maximum Output Current: 22 Amps

Performance: The VaporFi Vox II Mod performs quite nicely, especially since you can ramp up the device all the way to 50 watts.  I like that it has a wattage range where it isn’t outrageous, but still above the average watts being offered on most devices today.  Everything about the Vox II’s performance is perfect… it has the power, it can accept low resistance coils and takes an 18650 battery that is also supplied, so you honestly can’t go wrong with this mod when searching for an overall well performing device.  If I had to give any complaints, it would definitely be that the device steps down in power when the battery drains and there is a sub-ohm atomizer present.  I really don’t like that feature, but I can certainly understand why it’s there, for safety, so I can’t really complain too much if VaporFi has put their customers first with this device/chip being used.
