The Transformer Kit by Wellon Tech

Wellon Tech are not a company that I’m familiar with, in fact until I received the Transformer Kit to review, I’d never heard of them before!

But that can always be a good thing! New companies can, and quite often bring new and innovative ideas to the vaping table.

Build Quality & Design

The Transformer 75w TC mod is an incredibly compact device however, it’s not packed with tons and tons of features, in fact it’s very simplistic in that respect but it does contain pretty much everything you’re going to need.

The first striking feature of the mod is its size! Its compact and has a very distinctive styling.

The main body of the mod is constructed from a light-weight zinc alloy and there’s not much weight to the mod until you pop in your single 18650.

The stainless steel 510 threaded connection at the top of the Transformer mod is slightly recessed inside the body of the device. This doesn’t affect attaching the tank to the mod, in fact the threading was exceptionally smooth on both the mod and the tank connections.

Down the front of the mod we have a good sized stainless steel ‘Firing’ button with no apparent rattle. The ‘Firing’ button also doubles as the ‘ON’ and ‘OFF’ switch to the device. 5 click to turn ‘ON’ and 5 click to turn ‘OFF’.

Below this button we have an OLED screen, which by todays standards is on the smallish side but nice and clear with all information easily readable.

  • Battery Level Indicator
  • Coil Resistance (ohms)
  • Voltage
  • Wattage / Temperature
  • Coil Type (Ni, Ti or SS)

Below the OLED screen we have a and small flip down panel which covers the ‘+’ and ‘-‘ buttons. A nice little feature I think, as I’m forever accidentally adjusting the wattage on some of my mods due to having rather chunky fingers.

Like the ‘Fire’ button the ‘+’ and ‘-‘ buttons appear to be constructed from stainless steel and there’s no button rattle evident from either of these.

Button Functions:-

  • Turn the device ON and OFF:             5 Clicks of the FIRE button
  • Cycle through TC Coil Selection:        Press & hold ‘+’ and ‘-’
  • Rotate Menu display:                        Press & hold ‘+’ and ‘Fire‘
  • Adjust Wattage / Temperature:          Press ‘+’ or ‘-‘

Coil Selection Mode:-

<Ni> – Ni200 – Nickel Coil
<Ti> – Titanium
<SS> – Stainless Steel

The battery compartment on the Transformer mod is located through the rear panel of the device. The compartment door is held securely in place by two set of magnets located at the top & bottom of the panel.

Battery contacts appear to be brass or gold plated in colour with a spring loaded negative pin located at the top of the compartment. Battery fitting was straight forward and trouble free.

Finally on the mod, we have a micro USB port located on the base of the device. Not the best of locations but it works!

Transformer Tank

The Transformer tank is a little different to what you would expect from a Sub-Ohm tank. When I say different what I mean is, it’s tall. 60mm tall to be precise, excluding the threaded 510 connection.

At the top of the tank there is a standard black delrin 510 driptip attached to the top cap!

The cap is removable to provide a point for filling the tank with your desired e-liquid.

Threading on this was nice and smooth making the cap easily to remove.

The tank essentially comprises of two glass compartments. A top section which solely contains e-liquid and a bottom section which houses the stock coil and the remainder of your e-liquid. Between both of these sections we have an Airflow Control Ring with opposing air holes.

The tank can be broken down into its basic components to replace the stock coil and for cleaning quite easily and quickly. All threading on the tank was very smooth and clean.

A Note on filling The Transformer Tank

The capacity of this tank is 4ml. On the first few initial fills I experienced problems with air becoming trap in the bottom section of the tank. This appeared to mainly be caused by the size of the juice holes between the two tank sections and was increase by the high VG content of the e-liquid I was using. 70VG in this case.

After several attempts to correct this I discovered that tilting the tank at a 45 degree angle while filling allow some of the air to escape from the bottom section of the tank and substantially reduced the amount of trapped air bubbles.

Not ideal I know, but it was a good work around at the time.

How Does The Wellon Transformer Kit Perform?

I’ve been using the Transformer mod & tank for several days now and all in all its a reliable piece of kit.

Performance wise the kit did a relatively good job while using it in wattage mode. Both the 0.5 and the 0.2ohm stock coils performed as you would expect with flavour and vapour production being quite good.

Unfortunately I wasn’t able to use the kit in Temperature Control as the coils provided did not work in TC mode, which was a bit of a shame.

Following a little research on the internet I discovered that the coils are in fact Nichrome. So not suited to Temperature Control due to Nichrome’s very low TCR.

Hopefully, Wellon will be releasing Stainless Steel coils in the not too distant future.

In addition to this, the Temperature Control mode on the Transformer mod is very simplistic with the only options being coil selection and temperature adjustment.

Great for a first time user who want to experience Temp Control without all the hassle of adjusting loads of settings, but probably a bit too restrictive for a seasoned vaper who will probably like to fine tune their wattage as well as their temperature setting!

What I Liked

The simplicity of the Transformer kit make it a pleasure to use. You don’t need to read a 200 page manual just to turn the thing on.

Battery life was pretty good on this device as you wont be vaping at incredibly high wattages on either of the included coils. I was roughly getting a full day out of a 30A 3000mAh 18650 which suited me down to the ground.

What I Disliked

There are a number of issues I have with the Transformer Kit so lets start at the top of the kit and work our way down.

Firstly filling the tank. As mentioned earlier the tank is split into to sections. The bottom half mainly contains the coil and a small amount of juice while the top section is solely for the e-liquid.

Between both section there are juice holes which allow the e-liquid to travel from the top half down to the lower section and into the coil. These juice holes are quite narrow and its very easy to create an air lock between the two halves while filling the tank.

In addition to this, while vaping the device, the tank can become air lock in the bottom section preventing the juice to flow down and into the coil resulting in dry hits.

Bottom line is the internal juice holes need to be bigger, especially if your using a high VG base e-liquid. For this review I was using a 70/30 VG/PG liquid which didn’t flow through the tank very well.

Secondly, the mod has a Temperature Control feature however, you are only able to adjust the temperature setting. Power is automatically set to 75w and not adjustable. For me this is a big NO NO. I personally like to be able to fine tune my temperature and power settings to suit my tastes.

Thirdly, if your going to produce a Temperature Control device then at least provide a TC compatible coil in the retail kit.

Finally, we have the Micro USB charging port, which is located on the base of the mod. It just makes charging the device very awkward and cumbersome. Maybe thats more subjective than anything. Not the end of the world I know but it can be a little frustrating, but thats just how I roll 🙂

Final Review Verdict

The Wellon Transformer kit is a nice piece of vaping hardware. Yeah ok it has a few little bugs, but overall these aren’t too onerous.

Compact and relatively stealthy, this could possibly make for a good kit for anyone looking into making the progression from a basic setup into sub-ohming without all the fuss and technical know how of temperature control.

Pros

  • Mod is easy to setup and use
  • Leak-free tank

Cons

  • Tank is prone to air locking while filling
  • No Temperature Control coils included in kit
  • Position of Micro USB port can make charging awkward

Smoker for 25 years but now a seasoned vaper of four years. Started my vape journey on Cig-a-likes before moving very swiftly onto CE4's and Ego’s, which were to remain my preferred vaping hardware for a considerable length of time. When the infamous Nautilus clearomizer was released I move completely away from my beloved CE4 and also dumped my Ego for a tube type variable wattage device. Shortly after this I was on to RTA’s, RDA’s, VW mods and rebuilding. Recently I discovered the joys of Squonking and have become completely hooked.
