Wotofo Serpent RDTA styling and build quality

Wotofo often put a great deal of care into the construction of their atomizers and this one is no exception. The machining is superb with every part fitting together beautifully! I found the design highly appealing, streamlined but with some nicely rounded edges. Logos are kept to a minimum and this RDTA simply features “Serpent” nearly engraved on one side in a stylish font.

The overall size of the Serpent RDTA is relatively compact to so will tend to look good on most devices. Intended for single coil set ups only the deck features a clamp post system secured by Philips head screws. There are two generous wicking holes for your cotton and filling is accomplished via a side filling hole which is easily accessed by removing the top cap. The box includes two drip tips; a Stainless Steel one with a small Ultem piece and a black Delrin drip tip.

The amount of exposed tank glass is kept to a minimum so you are unlikely to accidentally damage it and you do get replacement glass in the box. The tank has an overall capacity of 2.5ml.


The airflow is simple but effective. It consists of one slot which allows the passage of air to flow through to the single hole in the deck. The airflow can be adjusted by turning the top cap. At its most open the airflow offers a restricted lung inhale style of vaping. Closing the airflow heavily down allows you to vape this RDTA mouth to lung.

Ease of use

This is a really easy to work with atomizer. Essentially it is built in a similar way to a Kayfun with your leads going in opposite directions. Fortunately there is no need to wrap the wire under the screws since the Serpent RDTA has two excellent clamps. The Philips head screws work well, hold the coil securely and I had no issues with them cutting the wire.

Ideally you want the coil as close to the air hole on the deck as possible and to get best results you should have both coil leads at the top rather than the bottom. If you think Hadaly RDA build you will know exactly what I mean.

Wicking is simple and I found it best not to have the wicks trailing more than one third down the tank. You do of course have to tilt on occasion but I’d rather do this than suffer dry hits. Thankfully you don’t have to worry about your wicks being in the way when filling since there is a side filing port, just make sure not to overdo it.

To dismantle the Serpent RDTA for cleaning you need to unscrew and remove the 510 pin in the base.

How does it vape?

After having primed the wicks I filled up the tank with some Heartland Vapes Sour Worm (American Candy style E-Liquid). I had decided to make use of one of the included twisted wire coils and in hindsight it was probably a very bad idea.

While the flavour is very good and the cloud production is quite generous for a single coil RDTA, the heat build-up with my chosen coil became a major problem. I found myself having to heavily reduce the Wattage and even swap the drip tip for the included Delrin run. The thing is the Delrin drip tip is quite short and shallow and as such the heat still tends to transfer to your lips.

Even though I have fallen into the habit of sticking Claptons in just about every tank and RDA these days this is one atty where I would advise you don’t do it. Even though there is a reasonable amount of airflow I didn’t feel like there was enough to keep things at an enjoyable level and the fact that almost everything is made of Stainless Steel just compounded the problem. In the end I swapped out the coil for a standard 3mm ID 26 gauge 0.8ohm coil and had a much more satisfying experience!

The draw was enjoyable but I did notice it getting a little choppy as I reduced the airflow but in all likelihood you could certainly put up with that.


I think this is superbly constructed RDTA from Wotofo and what’s really great is that it is marketed at single coilers. It is very straightforward to build and offers really nice flavour with a decent amount of vapour production! It’s only fault in my opinion is that being constructed almost entirely from Stainless Steel it has a tendency to get very hot and this transfers to your lips even when using the included Delrin drip tip.

Surprisingly this is one RDTA where I would suggest you restrict yourself to more modest builds and vape at a lower Wattage but all the same it’s a great offering from Wofoto!
