Hellvape Helheim S RDTA Review

Here we go again! Following on from the review of Hellvape’s new Helheim RDTA, I’ve got it’s brother here up for review today. This one is called the Helheim S RDTA, and is designed to be a single coil system (even though it can actually do dual coil) with slightly larger tank that it’s sibling and featuring 4 stainless steel rope wicks to pull the eliquid from the lower chamber to the build deck.

Let’s check out Hellvape’s Helheim S RDTA!

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

General Info

While both the Helheim and Helheim S are very similar, they are focused on two different types of vaper. The smaller Helheim that I reviewed the other day is for those who love genesis style RDTA’s but prefer them to be a little shorter, while still being able to throw largish dual coil builds in them. It’s typically built with cotton tails pushed down into the eliquid chamber.

The Helheim S RDTA on the other hand is significantly taller, with stainless steel rope wicks seated in the eliquid chamber, designed to pull the eliquid up to your secondary cotton wick that is tucked into the wicking ports on either side. The Helheim S is also designed to be a single coil flavour banger, with a slightly larger e-liquid capacity.

I am a little confused by this as I would have expected the dual coil design to have the larger liquid chamber, but who am I to say if it makes sense or not.

Regardless of my confusion, you’ll find that the Helheim S is all in all, very similar to it’s sibling. Both are 25mm in diameter, with very similar decks, dual airflow control caps, positioning pegs that also act as fill ports for the tank, 810 drip tips, 1/2 lock fill cap, locking top cap and Hellvape’s usual fantastic build quality.

The only real differences are the Helheim S’s caged tank, x4 stainless steel rope wicks, a taller tank chamber.

The Base/Deck

The deck of the Helheim S is of a postless design, cleverly thought out with large wicking ports off to the side, where you’ll find the rope wicks, side screw flathead screws for your coil legs, and two large fill ports on either side, that also act as locating holes for the pins in the top cap. Making sure your top cap always sits right with the airflow lining up with your coils perfectly.

While the Helheim S is mostly marketed as a single coil RDTA, you actually can use dual coils, and a pair of 2.5mm ID coils should work wonderfully in it. There is enough room for them. I set mine up as a single coil however, as Hellvape provided the one coil in the pack and I actually wanted to see how it held up in single coil mode.

Just like the Helheim RDTA, airflow comes in from the sides, with the lower airflow control inlet, pushing air into the small chamber under the deck and then up through the 10 holes provided for under coil airflow.

The deck is securely held together with the caged tank glass by orings and a central post that tightens down to ensure everything is sealed and secured.

One thing to note, the Helheim S’s deck does not have that slope off to the wicking ports like the Helheim does. Interesting that this was left out, but, being that the rope wicks are there, and Hellvape needed a sort of juice well, to create a seamless wicking between the primary and secondary wicks I’m not really surprised.

Top Cap

The top cap is a really nice, thought out design, it comes apart into two separate pieces, with the top section locking down onto the bottom section via a sliding lock system, making sure it doesn’t come off by accident, and ensuring your airflow sits right at all times.

From top to bottom, you’ve got an 810 drip tip with orings on the internal side of the actual top cap, the top airflow section with it’s 5 slots for adjustment, and the bottom section that contains a 10 hole honeycomb style underlying airflow for the top airflow, and a small cyclops style airflow ring below it for airflow under the coils.
The entire cap, simply pushes down onto the deck (as long as the locating pins are lined up) and sits in place.

One thing that I did notice about the Helheim S vs the Helheim, is that the Helheim S does not have the conical top cap like it’s brother does. Another interesting omission, but the flavour is great anyway.

Airflow

The airflow is cleverly done on the Helheim S, as it was with the Helheim. With two different airflow systems, one for across the coils coming in from the side (top airflow), and another feeding in from the side, and coming up from under the coils (bottom airflow) and plenty of incremental adjustments that can be made, will have you find your sweet spot in no time.

The top airflow has 10 underlying airflow holes, that are regulated by the rotation of the top cap, which has 5 slots in it, creating a smooth cross airflow across the coils.

The bottom airflow is only a small cyclops style airflow with adjustment ring, but that feeds through the deck block and under the coils coming out of 10 small airflow holes under the coils for an even flow coming up from that direction.

Hellvape have paid a lot of attention to the design of this dual airflow and it shows, being both highly adjustable, and smooth on all settings.

Filling

Remember I mentioned the two positioning holes either side of the deck earlier? Well, that’s where you fill. Simply whip the entire top cap off, and fill via one of these holes. The other is to allow air to get out while filling. A simple system, that simply works.

Building

Now to the build. I can’t believe I’m saying this, but this has to be the easiest deck I’ve ever built on.
Line your coils up, drop them in the slots, tighten the side screws, pulse and wick.
That is it! And it takes all of about 5 minutes to do, even when you’re trying to get your coils perfectly lined up.

Any Leaks?

None, unless you hold it upside down, but we don’t do that with RDTA’s do we? 🙂

Pros:

• Lots of build space on the deck
• Dual airflow for under coil and across coil
• Great build quality
• Clever little additions like the top cap lock and locating pins doubling as fill ports
• Single and Dual coil capable
• Excellent airflow options
• Really easy to build on
  

Cons:

• Chews through juice
• Decent tank size
• Not pocket friendly (but you wouldn’t really expect it to be)
  

Where to Buy:

As always with Hellvape’s stuff, you can pick the Helheim S RDTA up through their Australian partner, Vaporstate.
Vaporstate have the Helheim for $65 AU, which is a pretty good price for what you get. Go check them out now.

Conclusion

This is another fantastic RDTA from Hellvape, while it’s not gotten all of the features of it’s brother the Helheim, it’s pretty darn close, and likely focused toward a slightly different audience.

The larger eliquid capacity is nice, even though the wicking does promote this as a bit of a juice hog, but having the single coil option allows you to minimise eliquid usage, whilst retaining the flavour and ease of build of an RDTA.

Just like the Helheim, I particularly love the dual airflow control, the slide lock conical top cap, and position pins that are used to fit the top cap into place. Very clever additions.

All in all, this is one fantastic RDTA, a quality build, with a lot of thoughtful little fine tuning to make the experience even better than expected. Good work guys!
