Wotofo Serpent RDTA Preview

The Serpent RDTA by Wotofo is similar to the Avocado, but with an open deck dedicated to single coil builds.

Wotofo Serpent RDTA Intro

Wotofo continues to build on the Serpent brand with the new genesis-style Serpent RDTA. The new Serpent RDTA looks a lot like the original Geekvape Avocado 22, and is very similar in size, but where the Avocado is merely adaptable to single coil use with a chamber plug, the Serpent RDTA is a dedicated single coil RDTA.

With huge bottom airflow, and dual posts with large-capacity clamps, the Serpent RDTA opens the gap even further when compared to the Avocado. Fans of big coils will get excited when they see the open deck design — it looks like there is a lot of space between those clamps.

At 22mm in diameter, the tank is limited to 2.5mL, but the smaller size of the chamber should produce good flavor. Even so, filling the Serpent should be a breeze with its dual side fill ports.

In closing…

Wotofo Serpent RDTA black and silver

First and foremost: props to Geekvape on the OG Avocado RDTA. It remains a groundbreaking design and one that led to the many genesis-style RDTAs available today. The current crop of these RDTAs are simple to build, wick, fill, and use without leaking. I am a huge fan, and an avid single-coil vaper.

With the Serpent RDTA, Wotofo takes the Avocado 22 concept to the next level and paints a bullseye on the single-coil wish list with a wide-open, single-coil deck and large and adjustable bottom airflow, and those clamps will accept massive coils.

The ultem drip tip adapter will accept any 510 tip, and is a nice touch that should help insulate the included stainless steel tip from excess heat. Of course you may want to use the included wide-bore tip for bigger airflow.

As with the single-coil Serpent Mini RTA, I’m thinking that Wotofo kept the diameter of the Serpent RDTA at 22mm to reduce the chamber size and enhance flavor. If this Serpent lives up to it’s potential, I will happily trade capacity for flavor but if it doesn’t, the question may forever be: Why not 24mm with a larger tank?

Either way, I won’t be a bit surprised to see a Serpent 24 RDTA on the heels of this model, and why not? It looks like a great RDTA that will have single coil users rejoicing.
