The Sub-Ohm Slap-Down: What’s the Best Replaceable-Coil Tank in the World of Vape?

Recently Dennis the Menace chucked me two tanks to review for NEK Vapor. Now, I don’t make a penny for writing this stuff, but it is nice to be handed $100 worth of swag that I get to keep now and then. The two tanks in question are the Kanger Subtank Mini and the Joyetech Delta II.

I’ll dive down in a minute, but vaping friends, we have come such a long way in the six months since I’ve ditched tobacco! These are both replaceable-coil tanks (NO SWEAT!) that give the option of building your own coils. Both hit as hard as all but the best rebuildables that were available a short time ago, or even now. I recently ordered a Youde (UD) Goblin tank. The Goblin has been getting rave reviews among the hard-core vaping set because it is a really, really fine tank if you have the patience for it. I almost threw it out the window within the first three days I owned it, though. Yuck. Burned hits, hot tank, flooding problems — I had ‘em all. Then I sat down and figured out how to wick it properly, and I see what all the buzz is about. Massive airflow, great flavor and all that stuff! The Goblin is an authentic RBA tank and I’m trying to convince Dennis to put in some for you wire-twisters out there.

However, if I didn’t have the time and patience, I could have had nearly the same results (within about 5%) by popping a pre-built coil into either the Joyetech Delta II or the Kanger Subtank Mini. These are both hard-hitters, with smooooooth draw, huge vapor production, and wicked flavor. The air control on both is superb. If you like a traditional puff, choke the airflow down and go for mouth hits. If you favor lung hits, either of these will open up enough to chuff. Compared to the best airflow we saw even six months ago, these tanks are miles ahead.

Let’s have a look:


Here’s the Kanger. It’s a beautifully-made tank in a classy box. It comes with three coils — a 1.2 ohm, a .5 ohm, and a rebuildable deck. If either the 1.2 or the .5 don’t suit your fancy, you can custom-build. It comes with a nice wide-bore drip tip. It also comes with plenty of spares like o-rings and screws, as well as a pad of organic cotton and a screw driver.

Here’s the Joyetech Delta II:

It comes with excellent coils, and offers a rebuildable head as an option. In the box, you’ll find the tank (with a nice drip tip) and one spare coil. The other is pre-installed. Both are .5 ohms. Some devices may not be able to fire the .5 ohm coils. Until recently, many regulated devices had a lower limit of between 1.2 and 1.4 ohms.

For swag out of the box, a +1 for Kanger. I hate to say it, but Joyetch’s boxes are a little bland looking. No points here — both units are well packed in fitted foam wells, and the boxes are rugged, but Joyetech could up their eye-appeal.

As far as fit and finish, both tanks are beautiful. These are quality products with no sharp edges or visual flaws. For use in a rugged environment, I’d have to pick the Delta II for its stainless steel shielding. +1 there

While both tanks are priced exactly the same, adding the rebuildable deck option to the Delta will add an additional $14 or so. Unlike the Kanger, it offers “juice control.” If you like e-liquids that are around 50/50 PG/VG, they are thinner than high VG juices. There’s a little control you can turn  on the atomizer to keep your vape experience just right. And while there’s a lot of glass exposed on the Kanger, the Delta is built like — well — a tank. There’s a lot of stainless steel there keeping the word and concrete floors at bay. Neither the Kanger or the Joyetech appear to have any problem at all with thick high-VG juice, which is good news for those that folks that prefer it or have a sensitivity to PG.

The initial experiences we had with these were interesting. Both pre-made coils are fairly similar in design at first glance, but the Joyetech uses a vertical coil and a ceramic wick, while the Kanger uses a more conventional organic cotton wicked set-up with a horizontal coil. The advantage of a ceramic coil is that ceramic is very heat-resistant, and can be burned off to freshen things up. You can’t burn off cotton without destroying it. +1 for coil longevity to Joyetech. In my experience with both companies, Joyetech coils have a history for lasting longer in most cases. Another +1 for the Delta II.

However, things were a little fiddly with the Joyetech. Joyetech products don’t use a long contact pin, and we found that the replaceable coils wouldn’t fire on some batteries. The Kanger fired with everything we threw at it. +1 to Kanger for versatility out of the box.

The Subtank is a treat to fill, with a big, easy-to-see tank and a large area to drip juice into. It’s a no-brainer. The Joyetech is more of a hassle. The juice well is narrow, and you really can’t see how much liquid is in the tank from either the top or the sides. While the Subtank can be easily filled with a dropper from a juice bottle, the Delta II really needs a needle bottle and more patience. Another +1 for Kanger.

If you’ve ever replaced an atomizer, there shouldn’t be any mystery with either of these. The threads are clean, and there’s not a lot of fiddling about to change an atty. We popped the coils in, primed, and gave them a vape.

Both have a silky smooth draw, with no popping or gurgling. Wide-open, airflow is HUGE. While vapor production may not be right up there with dripping atomizers, it certainly is neck-and neck with just about any tank atomizer I’ve tried. Both Dennis and I commented that the flavor seemed just a little better from the Delta II. It’s crisper and a little more defined. +1 for the Delta II.

We also tried the rebuildable coil options on both, which come from the factory ready-to-roll. While putting a rebuildable coil into something like an eGrip transforms it from a good to a great device, there wasn’t so much difference here. In the Subtank, the rebuildable was almost identical in flavor to the pre-built coil. That’s not much of a surprise. They are almost identical in design. In the Delta II, the rebuildable coil seemed to take away the crispness of flavor we’d both commented on. Not much difference here, so no points for either tank. Both rebuildable decks are very, very small. If you’ve never wrapped a coil or wicked an atomizer before, these may not be the best place to start. I like having the rebuildable decks around, but I can see most people using these primarily with the factory coils. If I am out of coils when NEKVapor is closed, I’d likely just switch to something like the Goblin rather than fiddling around with microscopic screws.

Let’s total things up on our subjective scale and see where things sit:

Accessories in the box; overall packing and presentation: Subtank Mini +1

Ruggedness: Delta II +1

Flavor: Delta II +1

Coil Life: Delta II +1

Rebuildable Deck included: Subtank Mini +1

Adaptability to many devices: Subtank Mini +1

Ease of filling: Subtank Mini +1

Rebuildable Coil: Tie

Discarding the tie, out of seven categories, the Joyetech Delta II wins in three, and the Kanger Subtank Mini in four. However, these tanks are extremely close in performance. A year ago, tanks like these were only available from the best custom modders, cost a bundle, and took a lot of skill and trial and error to set up. Now, they are affordable for everyone and give fantastic results out of the box. Look at both of them, and see what fits your needs best.

Vape ON!
