Zephyrus V2

Today, I will be doing a review on an RTA (rebuildable tank atomizer)  made by Youde (UD). Youde is a company well know for their quality range of products in the vaping community. Over the past period they have released quite a few successful atomizers like the Bellus, Goblin, Goliath and last but not least the Zephyrus. The atomizer that I will be reviewing today is the Zephyrus V2, this version is an improvement to previous model the Zephyrus V1. During this review we will also be looking at the differences between the two tanks V2 vs. V1.

Build Quality

Zephyrus V2 The materials used in this tank are quite good (304 stainless steel)  and the finish is nice, I didn’t notice any rough edges or threads and the tank came perfectly clean (no machining oil whatsoever).

Mine tank came in stainless steel and so far it has stood the “test of time” fairly well. I have abused this tank quite a bit since for almost 1 month  it has been my daily vape. I didn’t encounter any leaks with the Zephyrus V2 as compared to V1 which would leak from time to time even with the prebuilt OCC heads (coils). The 510 pin on this tank is non-adjustable, I wouldn’t recommend the usage of this tank on the hybrid. The 510 pin is mounted around a rubber gasket, this can be removed however I would not recommend this since over time the rubber gasket can get loose and your 510 pin will begin to move side-ways.

I didn’t have any issues with pairing this tank to any of my mods, it has made a connection with all of them. The Zephyrus V2 also features  a unique design to prevent condensation, with the previous version I have had some issues with condensation building up near the airflow holes. The tank can be taken fully apart, even the airflow control ring can be removed for cleaning.


I have to be honest with you this is a good looking tank, especially with the preinstalled black O-rings. I also like the fact that their branding is quite subtle and looks very appealing to the eye. The tank also features a quick and easy top fill design, much more easier to fill now as opposed to version 1 where you had to take the small rubber gasket off and try to fill the tank through 2 small holes, in most cases I needed a medical syringe for a clean fill.

The airflow control ring has also been redesigned to prevent condensation at the bottom of the tank. For a tank that has a 6ml capacity this is fairly compact and low profile. What I really miss from the previous version is the heatsink, I really like the look and functionality of the heatsink however with this redesign this is no longer possible because this will make top filling a bit tricky, you would have to take off the heatsink with the drip tip and then open up the filling ports.


Vaping experience

Tasty flavour and good clouds with the pre-made OCC(organic cotton coil) heads, I took the 0.3 Ohm coil head and found that it best performed at around 40-50w, flavour was really nice however it does not match the performance in both vapor production and taste when using the RBA base. For me personally I think this tank really shines when used with the RBA base and when in need of a quick vape and time is limited for building you can just swap out the RBA base with an OCC head. Also the tank is pretty versatile as it also offers the option of doing mouth to lung thanks to the redesigned airflow system. For this tank you will have quite a nice selection of OCC heads as the Zephyrus V1 coil heads are compatible with the V2:

  • 0.6 Ohm Single Clapton Coil Kanthal A1 (recommended wattage 20-50W)
  • 1.8 Ohm Single Kanthal Coil (recommended wattage 10-13W)
  • 0.3 Ohm Dual Coil Kanthal A1 (recommended wattage 20-50W)
  • 0.5 Ohm Dual Coil Kanthal A1 (recommended wattage 15-40W)
  • 0.15 Ohm Ni200 Dual Coil – in series (This should be used in Temperature Control Mode Only, do not use this in power mode!)

Out of the OCC head collection, I have enjoyed the Single Clapton ones (0.6Ohm) the most, these have performed remarkably both in terms of taste and flavour production; these coils also lasted much longer than the others.

The RBA deck is a 4 post deck that can handle dual coil builds and single coil with the added ceramic adapter. The deck is fairly big and can take coils with a 3mm inner diameter, the bottom airflow holes provide sufficient air to cool the coils down. As I mentioned earlier, with the RBA deck this tanks really shines in terms of clouds and taste.

An added feature is the riffled chimney and drip tip, some would say this is a bit gimmicky however I found it to be something I enjoy, having that swirling effect in the vapor could be one of the reasons why the vapor tastes better.

Top-filling the tank couldn’t be easier, by twisting the top cap this reveals two filling ports one on each side to regulate the pressure easily while filling. Prior to filling out the tank I always put the airflow control ring to MTL (single hole) by doing so I haven’t experienced any leakage. Thanks to the top-filling redesign, now you won’t need a medical syringe for a clean fill, fine tip bottles or even fine tip droppers fit perfectly.



Changes in version 2 of the Zephyrus tank:

  • bigger RBA deck with improved airflow intake holes (U shaped)
  • bigger Philips head screws
  • Redesigned top-fill, twist to open juice fill ports
  • Chimney and drip tip riffled design (in the Zephyrus V1 only the drip tip was riffled)
  • Supports single coil builds thanks to the included ceramic adapter
  • Black version also available (Zephyrus V1 was available in stainless steel only)
  • Improved Airflow Control Ring with added MTL(mouth to lung) feature

Overall Impression

It seems that Youde (UD) has listened to their customers and has taken a product that was good but had a few shortcomings and has transformed it into something great. If for the version 1 of the Zephyrus there were some downsides (leaking in some situations, top fill design not so intuitive and easy) the Zephyrus V2 has taken care of all of that. If I were to change something in this tank, I would probably focus on the 510 pin to make it adjustable so that this can be safely used on mechanical mods or hybrids.

In terms of pricing this is fairly good for an authentic tank, the lowest price I managed to find at a quick look was 22.64$, if you do a better search you might even find it cheaper than that.
