Serpent RTA by Wotofo

I am sure that Wotofo need no introduction since they have brought us many excellent and cost effective products such as the Freakshow Mini and Sapor RDA’s. Not so long ago they released their first device, the Freakshow Tiny and now with the Serpent they bring you their first ever RTA.

The Serpent is a single coil rebuildable tank atomizer that has fully adjustable airflow which can cater to both lung inhales and mouth to lung vaping. In addition the tank features juice flow control so you can be certain you can happily use your high VG liquids without issues. With a 4ml capacity and a top filling method the Serpent looks to be a very attractive tank and of course like all Wotofo products it is very well priced.

Styling and build quality

In terms of looks the Serpent is a very well machined tank. It is nicely streamlined and all the parts fit without any problems. The only exception is the included drip tip which makes for a very stiff fit if you don’t remember to lubricate the O-rings. All of the other drip tips I tried fitted and the tank itself sat nice and flush with all my devices. In addition the 510 pin is fully adjustable.

The Serpent has large windows so you can clearly see how much juice is in there. In some ways the design reminds me a little the Aspire Triton and much like that tank the Serpent cannot be completely disassembled for cleaning. Thankfully it is less of an issue than the Triton and you can happily just rinse the main section under the tap. Of course due to the nature of this design it does mean that if you break the glass you will have to replace the entire tank.

The top of the Serpent features the juice flow adjustment and the top cap itself which unscrews easily to allow you to conveniently fill up the tank with juice.

The base of the tank unscrews to allow access to the tank. The deck is a two post design (not a Velocity style design) and is very similar to a Kayfun. It features a single large diameter air hole and has very wide juice channels. The post holes which are large enough for most builds seem a little unusual due to their location but they make perfect sense when it comes to building. The posts feature excellent grub screws which means they won’t cut your wire when tightening them.

Airflow

The Serpent features two wide slots for excellent airflow and makes the tank equally suited to typical or Sub Ohm builds. The airflow is very flexible and you can either vape it fully open for direct lung inhales or close it down heavily for mouth to lung vaping.

The airflow adjustment is slightly tight but not a big deal. The only real problem is that when the tank is fitted to box mods it makes it a little awkward to adjust the airflow. You also have to take care not to unscrew the bottom of the tank when adjusting it.

Ease of use

Filling this tank is very convenient but you need to remember to hold the juice flow adjustment with one hand and unscrew the top of the tank just below the drip tip with your other hand. If you don’t do it this way you will just end up opening up the juice flow.

You will have absolutely no problems when filling because there is plenty of room in there for your juice bottle nozzles. The juice flow control works really well and allows you to raise the chimney in the tank so you can happily vape thicker juice.

My build

The Serpent comes with two pre-made twisted coils but I decided not to make use of them. Instead I went for my typical 1.2ohm build using 28AWG Kanthal wrapped around a 2.5mm screwdriver. If you do decide to use one of the pre-made coils remember to add an additional wrap since the coil legs do need to be in opposite directions.

Installing a coil is really easy as long as you remember to leave the legs long enough. You first put one coil leg through one of the post holes and then move the coil as close as you can to that post. You can then easily gauge how much wire you need to cut off the other coil leg to get it to fit into the other post hole. Once you have the coil legs in both holes simply adjust the coil to be directly over the air hole and then use the included multi-tool or an Allen key to tighten up the grub screws.

Wicking is very straightforward but you don’t want the wick tails too far down the channels. Also keep in mind that you will need a decent amount of cotton in there because the juice channels are very wide. On my first build I made two mistakes firstly I didn’t use enough cotton and secondly I had accidentally opened up the juice flow control so I ended up with 2ml of Manabush in my lap when it came to filling. Now while any bottle of Manabush is a lovely vape it is absolutely horrible when you get it all over your jeans!

How does it vape?

I filled the tank up with Manabush Mojave Dessert which is a juice I vape a lot and because I am very familiar with it I know how it should ideally taste. If I remember right I was vaping at about 12-14W with this coil and I had the airflow really closed down for mouth to lung vaping which seems to be my preference these days.

I did of course try the airflow fully opened up but it was too airy for my tastes. However it does put out plenty of vapour and there is loads of airflow so you can happily put a Sub Ohm build in the Serpent if you want.

The flavour you get with this tank is lovely and makes for a highly enjoyable vape! Mojave Dessert tasted extremely nice and I got the full range of flavour notes when vaping it in this tank.

I wouldn’t say the Serpent was a hot vape like a Kayfun or my GP Heron 1.5 but it is definitely a warm one. Of course it will depend a lot on what build you put in the tank and the wattage you use it at.

Conclusion

To be honest considering the price and the overall excellent build quality I find this tank to be something of a bargain! Not everyone wants dual coil tanks or enjoys building them so it’s really great to see a good single coil tank like this. The very flexible airflow, top filling and ease of build make this a very desirable product that I think most people will really enjoy! The only minor flaw is the fact that the tank cannot be completely stripped down for cleaning but this can be easily overlooked when you consider the product as a whole which is excellent!

The Serpent was purchased from M-Vapes where it is currently priced at £24.95 (postage is included in the price).
