The Uwell Valyrian is a sub-ohm tank very similar to the TFV8 Baby Beast. In fact, it looks very much like it and performs just as well.

I wasn’t really too impressed with previous Uwell tanks like the Crown and Crown 3, but the Valyrian is a horse of a different color altogether. It has a nice big juice tank ( 5 mils, can be upgraded to 8 with a replacement tank sold separately) for all day vaping which I really like. Plus, I am a fan of top-fill tanks which this is also.

It has a flip-top fill design that allows you to open it with one hand and avoid accidentally unscrewing the glass from the base, which happens with other tanks when trying to refill. It is so easy to fill, just flip the top open and squeeze the bottle nozzle down one of the two juice openings and that is it. Snap it closed and you’re ready to vape. It doesn’t get any easier than that.

Uwell Valyrian Tank Testing and Performance

I got this tank over the weekend and couldn’t wait to give it a test drive. I spent about a week getting familiar with it and several hours of testing and reviewing the features and quality of the tank itself. Below are the highlights of my experiences with it.

A few things about the Valyrian that you should know if you’re planning on buying one is that it has really good airflow. There are 3 airflow holes that are adjustable. You can open it all the way or close it down halfway for a more restricted, more flavorful vape. The tank comes with what the manufacturer calls “airflow pins” to allow you to customize your vaping experience with this tank. 3 pins are included: 1 x wave pin, 1 x spiral pin, and 1 x unrestricted pin. At first, these pins were thought to improve the flavor, but what they actually do is change and modify the airflow coming into the coil head. They do not affect the flavor at all, but if you want more flavor simply close down the airflow a little until you find the sweet spot. Here are a few specification and features of the tank:

  • Size: 25mm Tank Diamenter
  • 5mL Standard Juice Capacity
  • Quartz glass reinforcement
  • Spiral Pin – Flavor-Focused
  • Unrestricted Pin – Cloud-Focused

Build Quality and Design

This tank boasts a unique design perk: Airflow Pins. The included airflow pins change the airflow in the coil head to improve the vapor production. It was originally advertised as for “improving flavor and vapor production” but I didn’t notice any real change in the flavor. It was good but did not drastically change. What did change slightly was the airflow, it was smoother and created more vapor. Another feature for this tank is a fill-line measurement on the coil head. It is a visual reminder not to vape the tank below this line to avoid dry hits and burning the cotton wicking of the coil.


Constructed out of stainless steel, the tank section is resistant to scratches and nicks, even when dropped from a table. I used it over a period of five days and a couple of times it was knocked over and rolled off onto the floor. The Pyrex glass tank resists cracking from acidic juices. I tried a citrus blend in it and it had no problems whatsoever. It is a well-made tank.

Ease of Use

The tank is really easy to use. Just fill it with e-liquid, attach it to your mod, and vape. That is all there is to it. Coil changes and cleaning are easy as well.

Vaping Experience

I really enjoy using this tank. In fact, it is one of the few I have that I will use. I have had issues with tanks leaking in the past and gave up using them. But this one changed my mind and I keep it in my collection for times when I will be away from home and don’t want to be bothered with dripping.


The flip-top design of the cap makes it really easy to refill the tank. No more twisting or unscrewing the top to fill. It can actually be done with one hand. There is a little button on the front of the cap that you press and it flips right up. Fill it with juice and snap it closed. Because of this design, there is no possibility of unscrewing your tank and juice leaking out.


The tank holds 5 mils of e-liquid as it is but can be upgraded to 8 mils with the replacement tank. It sells separately for $4.95. The two juice fill holes are wide enough for large bottle tips to fit for easy filling. The is tank had been great and I have had no issues with it leaking or flooding.


The vapor production on this tank is phenomenal. The airflow is smooth and produces plumes of vapor. This is a good tank for cloud chasers because it chucks them. The vapor production on this tank is slightly better than the clouds produced by the TFV8 Baby Beast, the slightly smaller version of the big Cloud Beast.


I did find that although the pins didn’t directly affect the flavor, the improved airflow in combination with adjusting the airflow control allows the flavor to be customized to where you want it.  For more flavor close down the airflow holes, and for more vapor open them all the way.


This tank is currently priced at between $25 and $30 dollars. This is a good price for a quality sub-ohm tank.

What We Liked

Unique airflow pins
Flip-top cap for easy filling
Fill line imprinted on the coil as a visual reminder
0.15-ohm dual coil heads rated for 95 -120 watts
4 Juice slots in the coil improve saturation and eliminate dry hits
Insulated drip tip doesn’t absorb heat
Hold 5 mils of e-liquid (8 mil tank sold separately)

What We Didn’t

– No variety of coil heads
– Vaping at high wattages will consume juice quickly
– No O-ring on the drip tip
– No RBA section

Final Verdict

If you are looking for a well-made tank with good airflow and great vapor production, this is it. And priced at less than $30, it’s a real budget-pleaser as well. It’s easy on the wallet if you need to replace an old, outdated tank and don’t want to spend a lot of money. It’s a great tank for the money and you’ll love how well it performs.
