The Wellontech Transfomer kit is an inexpensive 75-watt mod and 4 mL subohm tank combo priced around $37. Available in black, silver, copper, or brass finishes, this zinc alloy mod is TC compatible with presets for Ni, Ti, SS, and a temperature range of 200-600F. It uses a single-18650 replaceable battery with a load minimum of 0.1 ohm. A cool feature that first piqued my interest was the small hinged magnetic door that covers the +/- buttons. That prevents accidental power adjustments, and it makes for a more aesthetically “finished” look. It’s a simple yet nifty little addition to this industrial and ergonomic mod. Looks good so far… especially for such a low priced kit. But for me, the intrigue lies within its tank.
The Transformer Tank is relatively tall at ~48 mm, and it has a lot of parts by most standards. It holds 4.0 mL of juice which is a decent capacity these days (no mention of a TPD conversion). The coils – available in 0.2 ohm and 0.5 ohm – appear to be the Joyetech Cubis style of coil heads. Threading to the chimney system instead of the base, this type of coil head was popularized due to its ease of swapping and its virtual leak-proof nature.
The Transformer Tank is (sorta) a double decker tank. Its a top-fill, 4 mL tank divided in two by an “airflow base” that somehow also feeds the bottom tank. The top tank houses the chimney, and the bottom tank holds the coil head — but again, they’re separated by an “airflow base”. This is not your typical sub ohm tank. In a way, it looks like a sub ohm tank version of the Gragas RDTA, but no crazy pump-action here to saturate the wicks. From what I can tell, it’s just normal wicking like a Cubis coil (juice feeding from the bottom of the coil). And although it doesn’t look like it, the Transformer is technically a top airflow tank but the “top” airflow is in the middle yet above the coil. It’s more accurately top/side air since the chimney is above the air intake. As seen in the diagram, it looks like the airflow has a long way to travel, which will likely reduce heat, and maybe flavor. We shall see.
I just got an email from Wellontech that the coils are Nichrome (this was in none of the press releases I saw). Aside from Kangertech SSOC NiCr coils, I can’t find any other sub ohm tanks that use single-wire NiCr. Do you have thoughts on NiCr coils for a kit like this? I think confusion could ensue for some with Ni vs. NiCr on a TC mod. I wonder why Wellontech didn’t opt for SS since it goes both ways and the mod does TC. Either which way, it’s a good looking mod with an interesting tank design. I am interested at least in trying it, but not so sure I’d be itchin’ to buy it without seeing a few reviews first.
