If you ever thought SMOK made vaping gear only for cloud chasers, think again. The Chinese company has recently brought out the Spirals Plus tank, a slightly wider, chunkier version of the original Spirals tank. This 24.5 mm tank comes with two different coil types and a rebuildable single-coil atomizer deck (with pre-installed Clapton wire). The coils that come with the Spirals Plus tank are compatible with the original Spirals kit too. This vape tank is designed for low to mid-wattage vaping, with a definite emphasis on flavor. It sells online between $20 and $30. Let’s get down and dirty and see what SMOK can do in the flavor game, shall we?
Disclaimer: We received the Spirals Plus tank from SMOK for the purpose of this review.
SMOK packages the Spirals Plus tank with the usual attention to detail. Included in the kit are two pre-made dual-core coils, at 0.6 ohm and 0.3 ohm respectively. The coils are marked with the recommended wattage ranges as well as a “best” wattage recommendation. I’d treat these as suggestions, as other wattages may work better for you – and the e-liquid you’re vaping on.
An added plus with the Spirals Plus tank is that it comes with an RBA core. This deck is intended for single-coil builds, and comes with a Clapton wire pre-installed. The wire is held in place with two cross-head screws. In case these are too short for your wire type, the kits comes two extra sets of screws in different lengths. Spare parts include O-rings, screwdriver, and replacement tank glass.
Overall, the tank feels sturdy and well made. One of our samples has some minor threading issues with the top cap. It can be difficult to unscrew the tank while you still have e-juice inside it. Also, unscrewing the RBA core from the tank base can be a bit fiddly – the RBA housing should be firmly attached, so the core comes off in one piece.
Spirals Plus is a top-fill tank. Simply unscrew the drip tip and holder from the top of the tank and apply e-liquid into either of the large slots around the chimney. Note that this will be easier with unicorn bottles than with droppers.
The Spirals Plus tank is an interesting beast, in that it offers coil types with very different profiles. The 0.6 ohm coil has a much narrower inner diameter and from that you can see that it is intended for a more restricted lung hit, even MTL vaping.
After priming the coil itself, filling up the tank and waiting, I start off at around 18 W and work my way up. I’m vaping Cloud Corp’s Mereen e-liquid, a melon-infused, fruity blend, with a ratio of 70 VG/30 PG. Shout outs to Blair and Reece for the samples!
As DJLsb mentions in his video review of the tank, the small juice holes on the coil housing could lead to problems in wicking thicker e-liquids. And although 28 W is the recommended “best” setting for this particular coil, I start to get dry hits at this wattage. My personal sweet spot was around 23 W. At this wattage, the tank functions very well and the flavors are great. I would describe the hit as somewhere between mouth-to-lung and a restricted lung hit.
The tank has an airflow ring and four inlet holes. Sliding the ring to close off airflow closes all holes simultaneously. While this intensifies flavor and raises the temperature of the vape, the tank does whistle when airflow is closed off. This didn’t annoy me with headphones on, but expect a canine chorus if you live with dogs.
The 0.3 ohm coil has a wider inner diameter, and is more of a direct lung vape. With this coil, flavor is great, vapor is dense, almost creamy, and the clouds ain’t bad either. My favorite wattage on this coil was between 40 – 43 W and felt like the perfect marriage of flavor and vapor production. To be sure, it’s not a cloud machine, but at 40 W, what is? For the wattage that you run the Spirals Plus tank at, it certainly puts out.
Finally, the RBA core. Simply having this option is a big plus in my opinion. However, there is definite room for improvement. The deck holds a single coil in place with two cross screws. Although there are replacement screws in the kit, they all have the same size head. You’ll be able to hold a Clapton wire or similar in place, but anything thinner will be tricky without chunkier screws.
Even with the Clapton wire that was pre-installed, my ohm readings were all over the place – anything from 0.6 ohm to 0.3 ohm! This can be corrected while you have e-liquid in the tank by unscrewing the top cap and tightening the screws, but hold the tank glass down as doing this loosens the whole construction. The screws are small and fiddly, and can be easily stripped if you overtighten. Also pay attention that the end of the wires don’t extend too far out, or you risk an atomizer short.
As a final note I would add that even though the installed Clapton coil came out around 0.6 ohm for me, due to the larger e-liquid inflows the RBA can be run at a higher wattage than the 0.6 dual-core coil. I vaped on it up to 40 W with no problems. But the tank will leak if you puff into it while firing to prime the coil, so watch out for that.
The SMOK Spirals Plus tank is versatile and offers a variety of options for beginners who want to vape straight out of the box, as well as more advanced users who like to tinker. This is a tank which is long on flavor and offers different draws depending on the coil used. Some people may find the added height from the drip tip and holder irritating; it didn’t bother me personally. What I didn’t like was the way the tank whistled, and elements of the RBA core, which can be easily improved. The Spirals Plus is fairly chunky at 24.5 mm and you’ll need a similarly wide mod to avoid overhang. I would add that the 0.6 ohm coil works best with an e-liquid that has a 70/30 VG/PG ratio or lower. The 0.3 ohm coil handled a higher VG ratio without problems.
In conclusion, this is a flavor tank that does what it says on the tin. I recommend the Spirals Plus tank to anyone who’s into the flavor game and likes a low to mid-wattage vape.
