Steam Crave Aromamizer (4 & 7 ML)
The Steam Crave Aromamizer redefines flavor for tank based systems.
At the right is the unit we received for testing – actually, we received two units. The one at the right is the Steam Crave Aromamizer Supreme with a 7 ML capacity. We also received a black unit with a 4 ML capacity.
The only difference between the two is the glass housing and center stack. The build-decks, bases, and top filling components are identical.
The diameter of this tank is 25 mm ...
The package includes spare glass, allen key, spare grub screws for the posts, spare alignment keys, and spare O Rings and seals. (oh, and a Steam Crave sticker) ...
It's all packaged in a dense foam core to prevent breakage while shipping.
The entire unit can be disassembled for cleaning. With a total of 12 parts (including the drip tip), it's a fairly simple process and fairly straight forward. No PHD needed here.
The build deck is a generous size ... much larger than most. It's a "velocity" style configuration with the posts on the outer extremes of the base, coil holes that are offset and easier to align your coil vertically (without stressing the coil much). The tightening screws to hold the coil legs in place are at the side and use grub screws with a hex head. The allen wrench needed to tighten and loosen the grub screws is included in the box. The coil leg holes are 2 mm ... our first tests were with clapton coils and it was a distinct pleasure working on this base.
It's a simple design, and effective.
Air flow is through two oval shaped holes, one on either side of the base. Air flow adjustment is through a three stage stepped ring that allows for infinite settings maxing out at the complete size of the oval hole. The air flow adjustment ring is firm, yet easy to turn ... once set, it stays in place.
Above the air flow adjustment ring is the liquid flow adjustment ring. This is quite tight – you have to hold the base with one hand and turn the liquid flow adjustment ring to get it to move. Clockwise (viewing form the top) to shut off the liquid flow, counter clock wise to open. The liquid flows through two slots (partially visible at the bottom, through the tank). The slots are large, the liquid flow extreme. If you want to use this at high wattage like a dripper atomizer, you open the liquid flow to maximum. Vape regularly, and you adjust the liquid flow to help control the amount of liquid getting to the coil. Essentially, you dial in the amount of liquid to match your vaping style.
The base is similar to a dripper. There's no vertical slots for the wicks to fit into. There are four holes at the bottom of the build deck. E-Liquid flows through the outside of the build deck, through the bottom (below the deck base) and is delivered to the wicks from below the base.
At the left is an exploded view of the air flow channel. This is designed for air flow quite similar to a dripper. The air flow is directly across from the coils. One on each side, each aligned with the coil.
In that design is one of the problems with the Steam Crave system. When you tilt the tank, it leaks. The larger the liquid flow setting, the more juice is likely to come out of the air flow channels. (Please see the update below)
Regardless of the setting (other than full shut off), the likelihood of juice leaking out the air flow is directly proportional to the angle of any tilt. The only way of avoiding leaking is to keep the tank as upright as possible. We attempted to resolve the leaking with various wicking strategies (and will keep trying until we find a good one). Other users report a solution in building their coils in a vertical orientation and putting the wicks across the holes at the bottom of the build deck. We agree that a solution lies in how the wicking is placed in relationship to the liquid flow holes ... however, a vertical coil configuration also would mean less liquid getting to the top of the coil, and a wick at the top of the vertical coil that is not in contact with liquid in the base.
This is a top fill tank. The top section is knurled and quite easy to tighten and loosen. The sealing is excellent. Refer to the image at the right ... the liquid fill slots are excellent size, even eye-dropper style filling is possible.
This is an RDTA (Rebuildable Drip Tank Atomizer), meaning that even if you get liquid in the center stack, it's no big deal. It'll just make its way to the coil and generate even more clouds (and flavor).
Despite the comments about "leaking", this tank is a must have. It's easily the equivalent of dripper atomizers in terms of flavor and cloud generation. Easily. Plus, you get the benefit of having juice all the time the tank has juice in it. No need to drip every few minutes. Vape, flavor, clouds ... over and over and over again.
When you consider this is a tank based dripper, the leaking issue goes away. With a dripper, you do not have the option of laying it down without leaking, it's the same with the Steam Crave. In that regard, there is no disappointment.
We are in process of testing a few different brands of RDTA's. Without disclosing the others, the Steam Crave (both the 4 ML and 7 ML), share the number one spot for flavor and cloud production. All are similar specs, including the velocity style build decks. The main difference is how the top fill works and capacity. And, I must point out, there is one other RDTA that does NOT leak (read the update, neither does the Steam Crave Aromamizer Supreme – issue resolved). Hopefully the designer of this tank (BJ) is reading this and working on a fix to make this a competitor to dripper atomizers AND high-end clearomizers. At the very least, I would suggest the company make some videos and provide instructions for the ideal way to wick this tank to minimize or avoid leaking.
The coils we built for this are both clapton style coils with a total combined resistance of 0.32 ohms. The inner diameter of the coils is 2.8 mm. We used Cotton Bacon organic cotton for wicks. We did cover the E-Liquid flow holes at the bottom of the base, but our next wicking will be more generous with the length of the wicks so that we get a bit more "blocking" effect to prevent liquid flowing when tilted. Hopefully that will help.
We also have to point out that the wicking works in conjunction with the liquid flow setting on the tank ... when wide open, you have a lot of juice flowing through the large sized slots at the bottom of of the tank. Unless you are cranking out a lot of watts, avoid wide open liquid flow. We were using a Wismec/Jaybo DNA 200 unit, but set at only 35 watts. Even with the liquid flow nearly shut off, we still experienced liquid leaks through the air flow slots at the bottom of the base – but only when laying nearly on its side.
So, what’s the verdict? Is it worth it?
This is an expensive RDTA system. Focusing more on the dripper style capabilities of this tank, it's worth it. The flavor production alone is hard to beat ... even some dripper atomizers we have don't compare. Only the high end, deep well, dripper atomizers are at par with the flavor. Cloud generation is exceptional and can only be matched and exceeded by some dripper atomizers. All around, it is a "convenience" dripper system. It's not the style of tank you want to replace a clearomizer ... to avoid leaking, you have to keep it upright all the time. If you feel comfortable driving while dripping, this is the tank for you – you'll avoid "near-misses" with no refilling needed while you juggle a steering wheel between your knees. The only other issue we encountered is also with the air flow holes ... with the coils aligned with the air flow holes, we did get a bit of E-Liquid "popping" from being heated by the coils – right out the air flow holes. A bit warm on the hand ...

I contacted Steam Crave about the leaking issue. Their response was fast and thorough. Their recommendation was as documented above, it's all about wicking with enough cotton to completely cover the juice flow holes (with an abundance of cotton) at the bottom of the base. I followed their recommendation and used about twice as much organic cotton as before.
It's a distinct pleasure to report that this has resolved the leaking issue. We can now vape without worry of juice spilling out, whether vertical or tilted.
I'd again suggest to Steam Crave that they put together a tutorial or video on wicking strategies. This tank generates such outstanding flavor and clouds that more people should be using it. There are far too many reports on forums and Facebook about the leaking ... it needs to be addressed by the company.
PS. The extra cotton did not impact flavor or cloud generation.
