Introduction: Cosmo Kit by Vaptio

The Vaptio Cosmo kit is a baby device in comparison to most Vaptio kits. And the name itself isn’t quite as ‘Out There’ in comparison to Vaptio’s other releases. Despite the size, does that mean it can’t keep up with the big boys?vaptio cosmo kit review

Design and Build Quality

Cosmo Tank

The Cosmo Tank is a cute little thing, housing 2ml of e-liquid. But it has some very unique features.

For such a small tank, it all slides and slots together nicely and during my testing I had no issued with leaks, parts coming loose or faults.Cosmo-Tank-Exploded

It feels well made and the paint finish is very durable. At the top is a 510 Drip Tip fitting which has been compatible with all my other drip tips.

Unfortunately the kit doesn’t come with a spare glass which is a shame.


The Cosmo Tank easily manages mouth to lung (MTL) vaping, and direct to lung (DTL) vaping thanks to clever adjustable airflow options.

For MTL, you can set the airflow between 2 little holes on one side only to allow a more restrictive vape, but then twist it up to DTL airflow which opens up large slots on both sides. Cosmo tank mtl and dtl airflowIts super simple to adjust as the complete tank twists, leaving the base stationary which is a clever little feature.Cosmo tank airflow

No matter where you set your airflow, there is simply no noise, no whistle. Which is impressive in my opinion for such a diddy tank.


The Top of the tank twists off with a smooth 90 degree anti-clockwise turn, enabling the tank to be filled via the 2 large kidney shaped slots, and is easily re-assembled by placing the top cap on and turning until the notches are located and it drops back into to fill vaptio cosmo tank

Turn the top clockwise 90 degrees and its ready to go.


The kit comes with 2 coils, the C1 1.6 Ω coils is designed for the MTL experience, with the Wattage recommended between 10-15w. And the C2 coil is a 0.7 Ω coils designed for DTL, with a recommended wattage of 15-23w. Which in my opinion is baffling as the device itself is rated up to 30w.

So surely that means using the C2 coil at the Highest rating will damage the coils? It appeared not during my testing.Vaptio cosmo coil - C1 and C2

Cosmo Mod

The Vaptio Cosmo mod is just as cute as the tank with a fire button up top which when clicked 5 times will turn on/off the device, and a downward pointing arrow below that, which enables you to select between the 3 power options:

  • H – High (30w Output)
  • M – Medium (20w Output)
  • L – Low (10w Output)cosmo vape mod settings

There is a tiny RGB dot that appears when you release the fire button, which is used as a battery indicator:

  • Blue – High Battery (70-100%)
  • Green – Medium Battery (30-70%)
  • Red – Low Battery (0-30%)


When charging the device, the display will flash L-M-H and this will alter depending on the current charge level of your battery.

In The Hand

This super slender kit is super comfortable in the hand, the paint finish is nice and smooth and the only parts of the mod that slightly protrude are the fire button and the wattage selector. vaptio cosmo mod in handThe curve of the rear of the Vaptio Cosmo mod nestles nicely into your fingers leaving your thumb in perfect position to fire, and adjust the settings.

In the Pocket

As previously mentioned, this is a super small kit so its highly unlikely that you wont have space in your wallet for it, let alone in your pocket.

Setting the Tank & Mod Up

To set up the Kit for first use, its pretty simple:

  • Just screw the tank onto the mod
  • Twist top cap 90 degrees to access the filling slots
  • Fill with your desired e-liquid and re-fit the cap
  • Let the coil soak up the liquid for 3-5mins and away you go!

Changing The Coils

  • Unscrew the tank. (Sometimes the top unscrews leaving the coil in the base, sometimes the coil unscrews with the top. Either way it doesn’t matter)
  • Remove the glass
  • Unscrew the coil
  • Fit new coil
  • Refit glass tube
  • Re-fit tank sections

How Does The Cosmo Perform?

It’s hard not to compare this kit to the Pod System devices which have taken over the starter kit world during recent times. But seeing as its clearly aimed at the newbies, that’s what I’m going to do.

Flavour & Vapour

For this review I have been using a 20mg 50VG/5-PG Nic Salt called Caramel Tobacco by Momo Salt, and a 3mg 70VG/30PG eliquid called Cosmix BlueShift by Darkstar Vapour.vaptio cosmo tank coil replacement

C1 1.6 Ω coils

As far as MTL coils go, this has been a joy to vape on, with the airflow set at pretty much its lowest (Half of 1 hole open) and the wattage on Low, it delivers a lovely, slightly warm, restrictive vape with a nice amount of flavour and a discrete amount of vapour.

This setting feels extremely similar to smoking – Which should work nicely for recent quitters. I found with the airflow open any more, it didn’t feel as satisfying.

C2 0.7 Ω coils

Vaping this DTL, on High, with the airflow wide open on both sides, it delivers a surprisingly good vape, flavour is excellent and impressive vapour production for such a small tank.

Also, interestingly enough, the coil performed very well on the Low setting, with the airflow set to a minimum. (Half of 1 hole) SO I really don’t see a point to the 2 coil options. I happily used the 0.7 Ω coils to do my MTL and DTL vaping with no issues whatsoever, and on the low setting (Below the recommended wattage) it was a lovely MTL vape.

With regards to vaping above the 23w recommended, on High, I experienced no dry hits, or burning taste when vaping with the airflow wide open.

Both coils worked extremely well and it was surprising how little e-liquid I used during the past week. After 4 days on the 1.6 Ω coils, I had a look at the cotton and it still looked fairly new. So I’d say the coils are extremely durable and long lasting

Batteries/Life and Charging

The 1500mAh battery is more than enough to last a full day, and longer. Throughout my tests of this kit I only charged the device twice. Which takes around 25minutes.


  • A great all-rounder for a new vaper
  • Coils last and last
  • Not a heavy e-liquid drinker
  • Packs a punch for a small kit


  • The 1.6 Ω coil in my opinion has no purpose
  • No spare glass tube

Final Review Verdict

With the rise in Pod Systems, the Vaptio Cosmo is a Dark Horse. And it will probably struggle with sales due to Pod Kits. But if Pods aren’t your thing, this is a fantastic little device which offers an excellent vaping experience whichever way you vape it.

Hey Folks. Im Gaz, The Flat-cap Vaper. I’m 35, married with 3 kids and I just love Flatcap's and Vaping! I started my e-cigarette journey in 2014 when I entered my local vape shop and got so well looked after, I ditched my 10 year habit of 15 roll-ups a day within 48hrs. Following on from this, my Vaping journey began. I started a Youtube Channel at the beginning of 2019 and so far has had over 500,000+ views. I quickly upgraded my device and that’s when my geeky side took over and I began to experiment with making my own liquid, building my own coils and even my own mods! As a trained electrician I suppose ohms, wattage and voltage runs through my veins so Vaping has become my hobby and a passion that I want to share with everyone.


  1. Thankyou Ray for your comments. I was very impressed with this kit. And I have since given the device I tested to my father in law, who has since quit smoking! So its worked for him. Great job quitting the stinkiest

  2. Hi…after I changed my coil it won’t make smoke. It lights up and everything. I left it over night to charge and soak and still nothing. Please help.

  3. Thank you very much for a very detailed review of this device. I am a newbie to vaping, having made the decision to quit the fags for good. I am 70 yrs of age and should have done it years ago but better late than never. I am looking for a decent replacement for my “intro to vaping device” using the KiK 02 Vaping pen. Based on your review and that of many others I feel this could be the one compared to the Aspire Breeze 2 which I have also researched, which also had good reviews. What did it for me was the large capacity battery and the dual action MTL & DTL capability of this devise and the fact that it doesn’t use a lot of e-liquid during vaping. Thanking you again, keep up the good work and “Happy Vaping” Cheers Ray
