The Vaporfi VOX 40 TC mod is what you’d call a ‘beginners/intermediate vape kit‘.

What I mean by that is with a max power of 40 watts the device covers pretty much most of your vaping needs – looks smart too.

It works extremely well as a Mouth To Lung [MTL] vape and between 30 and 40 watts it actually hits quite well on a lower powered sub ohm coil.

Therefore if you’re new to vaping or are looking to try out Direct To Lung [DTL] sub ohm vaping – then this might be for you.

VOX is Latin for voice – so has this got me shouting its praises or mumbling insults?

We have covered a number of devices from Vaporfi in the past including the Rocket 3 vape pen, Vibe sub ohm tank and the Venom RDA. Oh.. And the superb Vaporfi Grand Reserve and Cosmic Fog / Vaporfi collaboration e liquids.

But this is all about the VOX 40 TC vape mod so let’s take a closer look. As always my thoughts and opinions are my own.

Key Features

As the name suggests the VOX 40 maxes out at 40 watts – I don’t have anything to measure that but can say that it certainly feels as though it’s hitting that mark.

So what we have is a pretty nice little device capable of both mouth to lung and sub-ohm vaping – or at least a gentle introduction to sub ohm vaping.

There’s also a temperature control option and TCR with three memory settings should you wish to go down that route.

And let’s not forget the clock feature which can be set to standard or 24 hour styles.

You can change the time according to the manual on the Vaporfi website – however I spent a good half an hour a day trying and lost the will to live!

And I’m not sure if it’s me but the Roman numeral VI is reading IV – just a blip I’m sure!

Other little features that are now becoming standard for vape devices are key lock and stealth mode and you can also set the screen protection mode – which helps save your battery if you’re running low on power.

There’s also bypass mode – direct input – and you can vape on the Vox whilst charging.

So there’s plenty packed inside such a tiny little device.

  • Hold + & – buttons to lock
  • Power button and + button together then + to enter screen timeout setting

Design and Build Quality

As we’ve come to expect from VaporFi the build is outstanding with nicely responsive fire and up & down buttons which look good too.

There’s a good amount of battery venting on the base and the USB charge port is on the side which means the device can be charged standing up right – always a bonus for me.

Design wise yes it’s a little boxy but the brushed stainless steel feels good in the hand and the Vox 40 has a nice weight to it – it feels like it could do some damage if you dropped it on your toe – yup I was that vaper.

At 22mm wide it will obviously only fit smaller tanks but it is extremely pocket and handbag friendly.

The large OLED screen is bright and I do like the clock on the front – I’m just in another time zone at the moment given I can’t for the life of me change the settings – hopefully my 8-year-old grandson will help me on that one!

I must admit on opening the box I got a little misty eyed as it reminded me of my first ‘box-mod’ the Heatvape Defender – kind of lol – it has the same max power too.

I think the Vaporfi Vox 40’s whole retro clean lines kind of thing looks good and with the JacVapour S-22 tank on top I did get a couple of admiring comments whilst out and about.

How Does the VaporFi Vox 40 TC Perform?

In power mode I can’t really fault it – it hits as hard as you want it to.

I used the JacVapour S-22 at 17.5 watts without any issues and swapping to the Aspire Nautilus 2 with the 0.7ohm coil at 21.5 watts and ramp up time was pretty much instant.

I popped on the Augvape Merlin Mini with a 0.5ohm build and vaped between 31 and 40 watts.

The vape was actually very pleasant – probably more down to the tank than my build – but again the ramp up time was super-fast with the tiniest amount of lag – barely noticeable.

Obviously, depending on your settings the battery life will change. However, the 2200mAH is more than enough for a day and a half vaping at 21.5 watts and just under a day whilst I was using it as a sub ohm device.

However, in Bypass mode – which in this instance basically pumps out full power for as long as the battery can hold out – I began work at 7am and by 11.30am I was almost out of power.

And remember you can vape whilst charging known as ‘pass-through vaping’.

Temperature Control Guide – Vox 40 Watt

I still haven’t gotten round to buying some temp wire!

So to put the temperature control settings I once again resorted to using my dinky little Innokin Slipstream tank set at 240C and at 33.5 watts.

As always the tank was dry and whilst the VOX 40 fired I got neither dry hits nor that nasty burning taste.

All I can say is based on that most basic of tests I reckon it seems to be working OK!

To customize your temp settings:

  • Click power button x3
  • Press + button until you see the TCR Mode
  • While mode is flashing scroll through the x3 memory settings
  • Click + button to choose the one for you based on your atomizer
  • To set up your own TCR mode:
  • When device is OFF press power and + button for 5 seconds
  • Choose the memory setting and use + and – to choose your settings

What I Like

Some might say it’s a little boxy but given its size it actually looks good with the slightest of curves taking that sharpness off.

The brushed stainless steel version I received [black is also available] looks very smart and looks as if it will take some knocks.

Like most of the VaporFi products its well-constructed with extremely responsive buttons and crisp clear screen.

Personally I think it’s a great little kit for a beginner or a more established MTL vaper looking to inch their way into sub ohm vaping.

What I Don’t Like

I was going to say the price however [and I’m not sure how long it will last] but VaporFi has knocked $20 off.

However that still means its $60 which for a 40 watt mod does seem excessive.

I don’t like the menu if I’m honest – far too fiddly and trust me I spent an age on the simple task of changing the time!

Final Review Verdict

Get past the tricky [for me] menu on the Vaporfi Vox 40 and you have a very smart classic almost retro looking vape mod.

Put it this way I’d happily carry this around if – and it’s very rare – I was in a suit!

It will grow with your vaping style and indeed switch between the two in a heartbeat.

30 watts is the bare minimum to get the sub ohm vaping experience and 40 watts on a decent tank and coil is all you really need for a good vape if I’m honest – who cares about the wattage wars!

It’s a classic little device that’s charmed me!
