Vapefly Brunhilde Top Coiler RDTA Review

Welcome back guys, you might not remember it but I reviewed the Vapefly Kriemhild Sub Tank a little while ago. It was a banger of a tank built with quality in mind. It had excellent wicking, huge capacity and a distinctive look that really set it apart from other offerings.

Today I’ve got the Kriemhilds brother in for review, but there are no pre-made coils in sight. This one is a rebuild-able, an RDTA to be more precise and it’s called the Brunhilde Top Coiler!

I’m not sure which came first, the Kriemhild or the Brunhilde, but they are both co designed by the German 103 team, each sharing similar styling, large e-liquid capacity and are focused on quality as well as functionality.

Let’s check out Vapefly’s Brunhilde RDTA!

Big thanks goes to Vapefly, who sent this out for the purposes of review!

General Info

The Brunhilde is quite a large tank, as are the other Vapefly tanks designed by the German 103 team, measuring in at 25.2 X 65.5mm you’ll find it towers over your mod quite a bit, but with the large 8ml e-liquid capacity, it’s easily forgivable.

It’s styled similarly to the Kriemhild Sub Tank with, the same top chamber, except this time instead of a continuous window around the tank to view your eliquid, the Brunhilde sports a flying scarab insignia in the middle of 4 small windows on either side.

This is where the similarities end however because the Brunhilde has a unique side fill port that exposed when spinning the top cap around, as well as a rebuild-able top deck and stainless steel rope wicks running down into the eliquid chamber to get your beloved eliquid up to the dual coils.

The Brunhilde also sports a protruding 510 pin for use on mechanical devices, a side fill port and 2 different types of airflow, inner chamber and outer. The outer is adjusted via turning the top cap section which provides you with a stepped adjustable airflow direct to the coil, and the inner airflow comes from the side of the deck flowing air up through the center of the coil blocks and out each side via a curved airflow section between the coils.

The Base/Deck

The deck is really easy to build on. It’s of course of dual post design but with both posts making up one single block right in the middle of the deck.

These posts provide 4 large holes for your dual coil build each spaced so that you won’t need to bend the legs of your coils before fitting them. You can fit some pretty large coils in here. Your coils simply plug in get screwed in from the side via the hex screws, so that they are facing in opposite directions.

Looking further down at the tank, it’s a glass tube inside a cage type of structure with orings at both ends to keep the glass sealed nicely. I did pull this apart early on, and beware if you do, as the bottom oring is quite difficult to get back into place when pushing your glass back in. (You can see it in the last picture above)

Inside the tank, you’ll find 4 stainless steel rope wicks that reach right down to the bottom of the tank and sit just above the deck once it’s all put back together. I’ve been quite surprised at how well these steel ropes wick, they simply work and push juice up to your cotton really well.

Top Cap

The top cap is a 2 piece design, with the upper casing movable to adjust your outer airflow, and the bottom section revealing the side fill port and inner airflow hole when swivelled around.

Inside you’re treated with a conical top cap to enhance the flavour, and push all of that vapour in the one direction, for a nice dense vape.

Airflow

There are two ways to adjust airflow on the Brunhilde.

The outer airflow that shoots air directly to your coils is adjusted by twisting the top section of the cap, using the stepped adjustment. I’ve found closing this down a little to give the best vape, usually closing down the top row leaving only the bottom row of 4 airholes on each side open. It’s quite a versatile airflow and you can really dial it in to how you like it easily.

The second type of airflow adjustment controls the airflow up through the centre of the coil posts. To adjust this you can twist the entire top cap to reveal a hole on each side. One side is the fill port where you can simply push your eliquid nozzle up to the hole and squeeze eliquid into the tank, (which works really well by the way), the other larger hole is for the internal airflow. You can adjust this a little to your liking, either close it right down, open it completely or leave it open just a little, the choice really is up to you and how you vape. Personally, I’ve always left this internal airflow open all the way, as I find it gives the best flavour.

Filling

As I mentioned earlier, the Brunhilde has quite a unique fill method. Provided in the side of the deck, and available through twisting the top cap to reveal the fill hole, eliquid is squeezed in while holding your eliquid bottle nozzle up to it’s chamfered hole and squeezing your bottle.

It works really really well, and as long as you are keeping pressure on the eliquid bottle nozzle, you can get a really clean fill with no issues.
I really like this, it’s quite ingenious, and a really simple method.

Building

Building is dead simple. Vapefly have given you some pretty big post holes to use all sorts of coils if you need to, and having a solid block in between the coils sort of creating two sections, makes placing coils really easy.

Pop your coils into the appropriate post holes, tighten them up via the side grub screws, trim the excess legs off and you’re good to go.

Wicking is also really easy, just like wicking an RDA. You really only need to make sure your wicks reach the bottom of the deck and the stainless steel wire ropes do all of the hard work for you.

I have not had a single dry hit on this tank, and that’s saying something, considering I tend to pack my cotton in quite tightly.

Any Leaks?

This is an RDTA so not keeping it upright will cause eliquid to over saturate wicks and likely give you some leakage through your airflow. That’s a user error thing though, and easily avoidable. This is not a tank you want to be putting in your pocket!

I’ve had zero issues with any leaking during my time with the Brunhilde, everything seals exceptionally well, and the build quality and tolerances are as close to perfect as you can get.

Pros:

• Large eliquid capacity
• Rebuildable
• Easy building and wicking
• Unique side fill port (quite ingenious)
• Unique dual airflow with airflow not only coming in from the sides of the top cap, but also from up within the centre block direct to your coils from inside.
• Protruding 510 connection for use on mechanicals
• Excellent build quality and tolerances
• Clever use of Stainless steel rope wicking
  

Cons:

• Tank is quite tall
• Cannot pocket it due to it being an RDTA
  
  

Where to Buy:

Vapefly don’t have an online store at the moment, but you can pick up the Brunhilde locally from Vapoureyes for around the $60 AUD mark. It’s a good price for the features you get, and the quality workmanship!

Conclusion

I’m quite impressed with this tank. It has a lot of bells and whistles and Vapefly have done a wonderful job making sure the build quality is there as well as everything being fully functional. They’ve really put a lot of thought into this one!

The stainless steel ropes provide excellent wicking, the unique side eliquid fill port is ingenious and works brilliantly. A lot of thought has been put into the deck design too with airflow also travelling up and through the centre block directing air outward to both coils at the same time the outer airflow is directing air in. With this type of design, the airflow travelling in from both sides meets on the coil on each side providing excellent flavour.

It is a little tall and that might be a bit of an issue for some, but for those who like big tanks with big styling, the Brunhilde RDTA is a great performer with next to perfect build quality and tolerances.

Great work on this one Vapefly, it’s going straight to my personal use rack as one of my first choices for it’s large e-liquid capacity!
