Introduction: The Preco One Kit from VZone
The VZone Preco One Kit comprises of the Preco One Mod and the Preco Disposable Sub-ohm tank.
A new trend in vaping is the use of Disposable Sub Ohm tanks. Basically you can still refill these but once the coil is past its best you cannot change it and have to dispose of the whole tank.
The tanks are also sold in packs quite cheaply with the marketing feature being they are easy to use and a pack of tanks is usually around the same price as a pack of coils without the initial outlay for the tank as well.
The Preco tank was one of the first of the disposable tanks I have seen and it has a top fill plug, a 0.15ohm mesh coil and is 24mm diameter.
To follow on from the Preco tank VZone designed a mod to pair with it – hence the Preco One mod.
The mod has an internal 1800mAh battery and a single button operation.
Below the tank on the top face of the mod are loads of LED lights, you can change the colour/pattern and these shine through the Preco Tank in a spectacular fashion! See the video below for an idea!

The specifications do not say what power the mod is outputting and it is not adjustable. However the tank apparently is best at 50-60W so I would imagine the output of the mod would be within those limits?
Basically this setup has all the convenience of say a pod mod but with more power and more flavour.
There are 4 colour options – Black & Orange, Stainless Steel, Black and Blue & Red.
So environmental concerns aside (yes I do feel these disposable tanks add to the issues of plastic waste) I will give this kit a fair going over.
I received this kit free of charge for review purposes and will as always report back honestly on my findings.

Build Quality & Design
I received the VZone Preco One Kit in the Stainless Steel version.
As you can see it is a bit of a chubby pen style but very light and pretty compact really.
It was very well packaged and the instruction leaflet despite the tiny text is well laid out and comprehensive.
VZone Preco One Mod
The mod has only one button which is the fire, on/off and LED controls. This is nice and clicky and responsive.
The top of the mod features the 6 LED lights and these shine through into the tank lighting the whole tank up!
On the base of the mod is the VZone branding, a battery vent hole and the required legal logos.
The finish is a very shiny Stainless steel but I am able to scratch this with a finger nail and the scratch will not rub off. Not a big deal on the SS version but it does make me wonder how durable the finish will be on the other colours.
On the side where the fire button is there is the “Preco One” branding. On the rear of the device is the micro USB port for charging.
Everything is sturdy, no rattles or wobbles and the mod stands up nicely on a desk.
VZone Preco Tank
The tank is very pretty there are two colours to choose from – Clear and Ash.
The tank in my kit and the spares were all in the clear style.
To fill you remove the top bung – which also is supposed to stay attached to the tank – however mine kept coming off. Luckily you get a spare in the kit and 3 spares in a pack of tanks.
To adjust the airflow the outer part of the tank kind of rotates. Really hard to describe but it caught me out a few times when I first used the tank as I just expected the bottom bit to turn as per usual with Sub ohm tanks.
Basically you have to grab the tank body and turn it clockwise or anti clockwise to open or close the airflow inlet. However turning anti clockwise does sometimes unscrew the tank from the mod! So the best way I have found is to hold the top of the tank with one hand and twist the tank body with the other.
Another slight niggle is that fact that there is so much plastic you struggle to see the liquid level. There are ridges and plastic seams on the tank so it is hard to tell when it’s full until it plops back out of the fill port.
You cannot remove the coil or drip tip they are all moulded into the tank assembly.
The tank, although as light as a feather, feels well made and I have had no leaks at all.
The mod and tank are supplied not connected. So you will need to fill the tank, charge the battery and screw the tank onto the mod.
Mod Basic operation
- Turn mod on or off = 5 clicks of the fire button.
- Vaping = press and hold the fire button.
- Adjust airflow = turn the tank to restrict or open up the airflow inlet slot as required.
- To change LED settings = Press the fire button 3 times to turn the Colourful Mode on or off. When Colourful Mode is on the LEDs will operate when the fire button is pressed and change colours. When Colourful Mode is off the LED light will light up Green during vaping.
- Battery life colours = the LED lights will flash twice after a short fire button press and change colour according to the battery charge remaining : Green = 100-40% charged, Blue = 40-10% charged and Red = 10-0% charged. This doesn’t happen after normal vaping, so if you want to check the battery remaining just do a brief press of the fire button. The lights also operate in the same colour code during charging.
- Show mode = to turn Show Mode on or off press the fire button 4 times. When show mode is active the LED lights will begin when the fire button is pressed during vaping and will continue to cycle through the colours for 15 minutes.
The mod also has the following safety protections:
- Short circuit – LED lights will flash 3 times
- High resistance / no atomiser found – LED will flash once in Blue when an atomiser is found and will flash once in Red when no atomiser is found.
- Low voltage (battery needs charging) – Red LED will flash 3 times when the voltage is below 3.2V and the device will turn off.
- Device overcharging – the device will cut off charging when fully charged.
- 8 second fire cut off (to prevent accidental firing and damage)
How To Charge The Battery
- Using the supplied USB cable install the smaller end into the charging port on the mod.
- Install the large end into a suitable USB outlet.
- The LEDs will light up red when charging.
- When fully charged the LED will flash green several times and then go out completely.
I timed a full charge using the USB on my PC (0.5A) and it took 2 hours from fully discharged to fully charged. This may be quicker on mains / powerbank type chargers.
How To Fill The Tank
- Pull up the filling plug to expose the fill port.
- Add e-liquid through the port whilst watching the level through the tank.
- Replace the fill plug securely.
- There are spare filling plugs in the kit and with the tanks so you can replace them if lost.
I tried to fill the tank with a 10ml bottle and a large chunky 80ml bottle and both worked fine. However I usually remove the drip tip from tanks to allow chunky nozzles to fit into the port easier but you cannot remove the tip on this kit sadly.
How Does the VZone Preco One Kit Perform?
Flavour & Cloud Production
The Preco tank has a 0.15 ohm mesh coil. The ratings for this are 40-70W and the best recommended voltage is 50-60W.
As I have no idea what power the mod is outputting I will try the tank on the Preco One Mod plus on an adjustable mod to see how it performs.
As this is a sub ohm tank it is preferable to use a thicker e-liquid – ideally 70% VG and above. Also you won’t require a high nicotine level as this is a powerful tank and anything above 6mg nic will be way too harsh.
I used my usual Stika Bombz Fruit Salad 80% VG and 6mg nicotine in this kit.
We tell you about e-liquid mixtures in our guide to PG and VG.
VZone Preco One Tank Performance
Tank On the Preco One Mod
The coil is a mesh type of 0.15ohm which seems to be a common place to start. For instance the coils on the Freemax Fireluke Mesh are similar so I am hoping the flavour and vapour output will be close too.
I can happily report that this tank is really lovely!
Plenty of vapour and lovely flavour too – when you think this is a cheap throwaway tank I have to admit my expectations were quite low. But I really really like the output from this.
Airflow wise you can fully shut off the airflow in the closed position and in fully open there is a slight restriction – not a wide airy airflow but not going to send you boss eyed sucking either.
I usually have most sub ohm tanks set to the middle position for a restricted DTL vape – I am using the Preco tank mainly in the wide open setting to give you an idea of the airflow.
To read more about DTL and MTL vaping styles read our guide.
After a week of use the flavour and vapour output is exactly the same – so far the coil life seems pretty good!
Tank On the Voopoo Alpha One Mod
I popped the Preco tank onto my Voopoo Alpha One mod and started off at 40W.
This was OK quite a lot of vapour but not much flavour and feels well below the power output of the Preco One mod.
At 45W a lot of vapour – cloud city but again the flavour isn’t starting to shine yet.
50W is getting closer to the output of the Preco One mod I think. 55W seemed to be where this was happiest. I did try 57W but there was a hint of dryness like if I push it further it will make my lungs burn with a revolting mesh dry hit. So I think I will let the coil bed in a bit and see if I can get up to the recommend max of 60W.
I transferred my well used (week old) Preco tank which was used on the Preco One mod onto the Voopoo to see if bedding in the coil allowed me to up the power a bit.
At 57W this time the output was great – it was a bit warmer than on the Preco One mod but not much improvement otherwise.
I took it up to 60W and more of the same really – no dry hits and it performed well.
So I would recommend letting the coil bed in for a few tank fills before going above say 50W as it was threatening to cause dry hits with a newer tank.
VZone Preco One Mod Performance
I have to say even from my first couple of vapes the fire time seems really quick and responsive.
The LED lights might be an issue for some, you can however sort of turn them off and they will only light up when vaping and flash twice after a button press to show the battery level. However if you want a full on vaping disco you can set it to “Colourful Mode” or even worse is the “Show Mode” where the lights carry on for 15 minutes after you last pressed the fire button.
The battery life will depend on which setting you have the LED lights set to. For instance the Show Mode will have the lights operating for 15 mins after last press of the fire button so this could really impact the battery life.
I got 2.5 hours regular vaping with the lights set to Colourful Mode (Lights operate whilst vaping but not after releasing the fire button).
- The simplicity of a pod mod with only refilling and charging to contend with.
- Nice looking kit
- Light weight and compact
- Quick fire time
- Excellent flavour and vapour from the tank.
- Isn’t as thirsty as some sub ohm tanks.
- Pack of 3 tanks is equivalent price to a pack of coil heads
- No leaks or malfunctions
- After a week of use the flavour and vapour still seem great.
- Airflow adjustment means rotating the whole tank body – if you do not grip the top of the tank you will keep unscrewing it from the mod.
- Obvious environmental concerns regarding the waste of disposing of the whole tank.
- Filling plugs will be easy to lose – thankfully you do get spares.
- Not exactly “stealthy” even with the light modes turned off the LEDs still flash when the fire button is pressed and also to show the battery level – the whole tank lights up!
- Mod body scratches quite easily – this is on the SS version so not sure how durable the coloured versions will be?
- Battery life isn’t amazing – this is quite a high output mod and needs a bigger battery really.
Final Review Verdict
I am struggling to find anything really bad about the VZone Preco One Kit – apart from a few niggles. The airflow adjustment is a bit annoying, hard to see the fill level and the filler plug becomes detached from the tank when refilling.
Aside from the waste of plastic from the tank being disposable I really like it. I can see how it would be useful if you were away from home for a while – take a pack of these, no coil changes, no worries about broken tank glass etc.
The battery part works perfectly fine with a surprisingly quick fire speed and you can set the lights to only come on whilst pressing fire if you find them too annoying.
The power output of the battery seemed to perfectly match the tank – when using the tank on another mod I found 50-55W to be similar output. Moving up to 57W was pushing it a bit so it does feel like the tank and mod are very well matched in performance to get the optimum performance.
Sadly though as the mod does output around 50W the battery life isn’t great and it is only 1800mAh. Similar output vape pens tend to be from 2500-3000mAh and I think this kit would benefit from a bigger battery capacity.
I would really love for VZone to produce a sub ohm tank with the same coils as the Preco. Where you can just change the coil and not have to dispose of the entire tank. The flavour output is excellent but my conscience wouldn’t allow me to use these tanks all the time.
