VaporFi VOX Mini 40 Watt Box Mod Vaporizer Review

“With a Price Like This and No TC, it Must be Sleek…”

Rating: 4.9 of 5 Stars

Price: About $80


VaporFi VOX Mini 40 Watt Vaporizer Review, By J. C. Martin, III The VaporFi VOX Mini is a wonderful little device. Sleek and high-tech, the regulated mod is light and powerful. Has anyone ever preferred a device without TC (temperature control) as opposed to one that does use temperature control? Surely. I vape with TC devices all the time, yet stick mostly with Kanthal coil builds and variable wattage control. The VOX Mini 40W does not have TC, however it does go up to 40W, which is enough for some of my more advanced coils, which I sometimes use at 29.5 watts and up to 40 watts or more. More on coils below. Just remember many coil builds have less resistance than 0.20 ohms, which is the minimum resistance for the VOX Mini 40 watt box mod. Also, VaporFi has a few great choices of suggested atomizers for the VOX Mini 40W.

There are two main reasons I like this device. One, it looks pretty state-of-the-art, with its mirror-like screen display. The other feature, even more important to me, is that while you can charge it with a USB cable, the USB charging port is not on the bottom but on the front of the device. It is an attribute that is appreciated, as the device can stand upright while charging. Most people who vape with it will prefer a sub-ohm tank, such as the VaporFi Hybrid Tank. More on the suggested atomizers below.

Another plus to mention is that the device uses a 35A battery, which is safe for a great deal of coil building. One possible drawback is the cost. Though the device is simple, powerful, and sleek, the mod lists for $80, and its suggested atomizers are pricey, too. Together, the mod and a suggested tank together make for a price high enough to cover overnight shipping and a starter kit from a varied assortment of other competing companies specializing in fully equipped TC starter kits.

VaporFi VOX Mini 40 Watt Box Mod Thoughts and Photos

VaporFi VOX Mini 40 Watt Vaporizer Review, By J. C. Martin, III The VOX Mini 40 watt box mod is a great device. Its price is a little high, however it works great. As thoroughly covered in the other review here in Spinfuel on this same device, the price comes with a high quality product. Once you get over the cost and .3 ohm resistance minimum, you can really find the benefits for purchasing the item. It is a ‘light,’ simple device, so one can carry it easily in their pocket or purse, and it is powerful, easy to use. The VOX Mini 40W is fun to build coils for, especially if you like the looks of a 22mm RDA or authentic VaporFi Tank. The suggested tank for this device is the VaporFi Volt Hybrid Tank.

I built more than one kind of coil for the device; the first one did not work out, because it was .18 ohms. A few pictures of it is below. The first picture is of the Doge V2 22mm RDA, by Baj Ltd., a great RDA for very low-resistance coils, due to its 3mm post holes. The next two pictures show two 7-wrap, 24 gauge Nichrome 80 coils installed in the Doge V2 Competition RDA. The build worked fine on some other mods.

The next three pictures are of the gift box and the VaporFi VOX Mini 40W.

Before I built coils specifically for the VOX Mini 40 Watt Box Mod, I tried out a previous build for another device with an RDA with a more acceptable ohms resistance, and it worked fine. The two pictures below show the Mutation XS Mini V4 22mm RDA with a dual Ni80 Ribbon-Twist 30 gauge Ni80 Clapton coil build wicked with 2mm Silica wick and saturated with Aelos Smoothie (tastes like Strawberry Blueberry Malt) flavored e-liquid, a great way to vape. The ohms reading was .3Ω. If you ever attempt this advanced coil, I recommend a diameter 1mm less than what is seen in the picture. I rebuilt this same RDA with two 3mm 26gauge Ni80 coils, which read .3 ohms and vaped well. The funky mouthpiece is one I found on FastTech.

The next build I tried was the best choice, in my opinion, so far. Though I usually use two 7-wrap, 26 gauge Kanthal coils for builds of this nature and vape at 29.5 watts, for this build I used Ni80. Two 7-wrap coils of Nichrome 80, 26-gauge wire gave a resistance reading of 0.3 ohms. This is a low resistance build with a minimal ramp-up time, and it works great at both 25 and 40 watts. I use it on 40 watts. The four pictures below are of the dual 26-gauge Ni80 build in a Baal V2 22mm RDA, by Madaotech. The Baal V2 RDA is one of the best RDAs I know of, due to its appropriate post holes, deck space, and, mainly, its protective ‘splash resistant’ mouthpiece which is great for macro coils. It also allows for a large amount of airflow and has a cool horned lamb skull engraved upon its barrel.

One thing I really like about the VOX Mini 40 Watt Box Mod is the Battery, as it is a 35A, 2,500 mAh capacity Lithium IMR. These batteries can handle more amperage draw than 20A, 25A, and 30A batteries. These notions mean more for coil builders with mechanical mods that vape with coils with resistance under .3 ohms, however the battery is about the best one would prefer in the realm of 18650 batteries.

As far as the charging goes, when I charged the model I received, it only took about 30 minutes to charge fully. When the battery goes low, it should not take over 3 hours to charge fully, and the VOX Mini 40W shows an animated battery OLED icon showing that it is charging when it is plugged into the USB port of your computer or wall adapter. The battery light indication icon shows you when the battery is low long before the battery gets too low to use, which is a nice feature, because when you drain a lithium battery out all the way before recharging, it will not last as long.

The VOX Mini 40W is a simple, high-end device. It does not require any knowledge in the realm of TC, and is great for Kanthal coil vaping. Some vapers prefer Kanthal over Ni80 due to its having a higher resistance. Both choices allow for massive flavor and cloud production; I like the Nichrome due to its faster ramp-up time. With a 510 connection and the ability to produce 40 watts of regulated power, the VapoFi VOX Mini 40 watt box mod is a choice mod for many of us.

In conclusion, it was a difficult decision not to give the VOX Mini 40 watt box mod 5 of 5 stars. I just could not do it. It is a very high quality device, sure to last a long time, yet the price is a little high, even if you get what you pay for. It also does not have TC, which, as I know, some people just do not vape with, anyway. Other than those notions, I do love to vape with the VOX Mini 40W for many reasons. Again, it does not have TC, and I happen to like that. And, as I indicated above, the USB port is not on the bottom, which is my favorite feature of the device. I do wish that it could go below .2 ohms in its resistance minimum, however it is really no big deal, as most coils that are best for 7 to 40 watt vaping do not require ohms resistance levels below .3 ohms. Sleek and light, the VaporFi Mini 40W is a great choice for both experienced vapors and those new to vaping who are giving up smoking. If at all possible, I do suggest a VaporFi recommended atomizer for this device; they are available for order from the VaporFi Website, as is the VOX Mini 40W. All in all, the VaporFi VOX Mini 40W is an awesome device and I do recommend it for the reasons above. Thank you for reading and vape on.
