Build Quality & Design

A lovely looking RTA straight from the box.wotofo serpent alto rta deck

The delrin drip tip/top cap assembly is the correct size and can be removed if you wish to use your own. wotofo serpent alto drip tip

Below that are some cooling fins to dissipate the heat. They keep the drip tip nice and cool for when you are chain vaping or vaping at higher wattages.

The posts on the deck are definitely a bit different to the norm. One either side of a central airflow as well as two airflow holes below where the coil sits.

The airflow control ring is nice and smooth, but has the right amount of resistance to prevent it from being accidentally adjusted whilst in the pocket or when in use.

It also has a pin to prevent the airflow from rotating a full 360 degrees

All the threads on this RTA are clean and crisp. There are no squeaks or sticking during assembly and disassembly.

Prebuilt Clapton Coils

Included in the Serpent Alto RTA are two prebuilt twisted kanthal coils. They fit nicely on the deck and produce some good flavour and reasonable clouds!


  • The multi-function screwdriver is great. This helps you unscrew the grub screws fairly easily and also incorporates two different allen key sizes.
  • There are plenty of spare o-rings and also a blue and red one so you can swap the standard black one out for one of these to match your device.
  • The cotton was your usual organic square cotton pad. I personally prefer not to use this type as it doesn’t offer the best flavour for your atomiser.

How Does The Serpent Alto RTA Perform?

After filling the tank up with juice, I had no problems with any leaking or flooding. Wicking is extremely easy to do with the simple deck design.

How To Fill The Wotofo Alto Serpent RTA

Simply unscrew the top-cap/drip-tip assembly and you are met with two kidney shaped holes either side of the chimney.

The holes are big enough to let a good volume of e-liquid in and air to escape out the other side.How to fill the wotofo serpent alto rta

Just remember to close off the airflow before you fill the tank up to avoid any possible leaks!

Coil Performance (Included Twisted Coils)

The included twisted kanthal coils come out to 0.36ohms, which is a great all round resistance, not too low and not too high!

30w Test:

With the airflow fully open, you get a nice, cool vape. Clouds aren’t massive and flavour is OK. This tank can definitely take higher wattage than this.

40w Test: Again, the airflow fully open.

A slightly warmer vape than before, no spitting or crackling though. Flavour is a lot better than at 30w and cloud production is marginally better!

50w Test: Airflow fully open again

A lot warmer than vaping at 30 and 40w. Coil ramp-up is more or less instant. When taking 3-4 second puffs I’m not experiencing any dry hits or loss of flavour.

But I feel that I am getting to the higher limits of this build. But lets take it to 60w to see how it performs!

60w Test: Airflow fully open

On the first inhale, I’m getting a dry hit almost instantly. This is probably because the wick isn’t wicking fast enough to replace the e-liquid that is being heated up.

Overall, I would say that anywhere around 40w is great for this tank.

You’re getting a good combination of ramp-up time, flavour, clouds and you’re not drinking through the e-liquid like what you would at wattages over 50w!

I would also recommend that you have a play with the airflow, although it is semi-restricted when fully open. I feel that it doesn’t make a massive difference to the flavour, but I did find that restricting the airflow was a little less pleasurable for me.

Ease Of Build – How To Build On The Serpent Alto RTA

The Wotofo Serpent Alto RTA is extremely easy to build on! The deck is small, but it’s simple to build on.

The post holes aren’t the biggest I have seen, so you may have trouble fitting in some complex coils.

Simply thread either leg of the coil through the posts and tighten down.

Make sure that the coil is directly above the bottom airflow but also next to the vertical airflow which is situated between the two posts.

Tuck the wick down either side of the deck, wack some e-liquid on and you’re good to go!

What I Like

It’s small, compact and easy to build on. As with the Troll RTA, I am finding little if not anything to dislike about this RTA.

It doesn’t need massive wattages to produce good results, so would suit a mod that are capable of outputting 50-70w or higher. This would also be a great little RTA for beginners to try.

What I Dislike

Again, I am honestly finding little to nothing to dislike about this RTA.

If I was to be really fussy, the e-liquid capacity could be bigger and possibly a bigger deck to build on. But to be honest, it’s not a massive problem at all!

Final Review Verdict

I’m loving the Wotofo Serpent Alto RTA! Another cracking RTA from Wotofo. Great for anyone who is looking for a new RTA to try out and I’m sure that it won’t disappoint.

If I Lost or Broke this RTA would I Replace It?

Most definitely! Easy to build on, a great vaping experience, good flavour and clouds, the list goes on! and at around $34.99 it’s a bargain as well!


  • Great flavour across the wattage range
  • Good clouds
  • Easy to build on
  • Easy to disassemble and clean
  • Good quality feel to the RTA and accessories


  • Deck could be bigger
  • E-liquid capacity could be more

Hi, my name is Dean and I have been vaping since April 2014. I decided to start reviewing back in mid 2015 as my friends kept asking me about different e-liquids I had tried and whether they were worth buying. So I thought I'd start on Instagram writing written reviews for them to read. Then several months later, I saw that people were publishing reviews on YouTube, so in late 2015 'TheDevilVaper' was born! And since then, I have built a following across social media and I'm reviewing anything from starter kits to mech mods. Budget e-liquids to premium flavours and prebuilt coils to carry cases. To me, vaping is more than just a way to quit smoking. It is now a hobby. And a hobby that I have great pleasure in doing! And if my reviews help people ditch the cigarettes, then it's a job well done. TheDevilVaper


  1. Forgot to mention how cute it is lol. Makes equal sized RTA/RDTA’s look larger because of the heat sink fins instead of a full sized top. Even a Goblin Mini looks big next to it. Perfect tank for a eLeaf Pico IMO.
