Today I’m going to be taking a look at the Seven 22. This is actually the first Chinese variable wattage mod that goes over 20 watts – at least I think it is, chime in below in the comments if I’m wrong.
This is actually the precursor to a 30 watt mod they are working on. Personally I think 8 watts is bordering on splitting hairs anyway, but that’s neither here nor there.
This mod does everything your standard VV/VW mod does, plus a few unique features.
First and foremost, it uses a 26650 battery. This is a HUGE battery if you’re not familiar with it. If 18650 is loosely related to a AA, then this is loosely related to a D. On the plus side, the 26650 batteries have a high amp limit and much longer battery life.
This is ONLY variable wattage, not variable voltage. The wattage adjusts from 7 to 22 watts, hence the name. This is a marked improvement over the 15 watt max you may be used to if you haven’t owned a DNA20/30 device.
This mod WILL fire sub ohm coils. I’ve fired atties all the way down to 0.5 ohms on this thing with no problems at all. Personally I think this is a HUGE plus and it helps make sub-ohm vaping a little safer to boot.
The most important thing you need to know about this beast is that it is absolutely HUGE. It’s got a super wide diameter, somewhere in the 35-40mm range, and it is significantly taller than any other mod I have. Here’s a picture for scale:
You can see that my atomizer looks wildly out of place on this thing. LOL. I still don’t have one yet that fits anywhere close to flush.
What I DIDN’T like about the Seven 22
Overall this thing runs pretty smooth, and there aren’t any glaring issues with it.
First off, a minor issue – I really don’t like mods that have a lot of options and only 1 button. It seems to make it take significantly longer to do just about any action, where any mod with multiple buttons always seems to move much faster. It’s a very minor issue, but something I still find to be a PITA nontheless.
More importantly, the main thing I really do not like about this piece is the size. It’s ridiculously large. It’s quite heavy – mine clocked in at 15.5 ounces with a 26650 battery installed and Lotus RDA sitting on top. I don’t think I have any other device that comes anywhere close to that.
The weight isn’t such a big deal, but the size is really awkward. It still fits OK in the hand, but it is huge. Anyone who sees you with this thing will laugh at you for sure. Not only that, but it is very difficult to find an atomizer that will sit flush on it. Now as I am writing this, there have been a couple larger diameter atomizers that have very recently come out, but there aren’t a lot available right now, and I don’t even know if I would like one that large anyway. So pairing an atomizer with this thing is nearly impossible.
Basically, this is not really a good mobile device – it’s the kind you more likely would keep at your desk or in your car, and take something else out with you while you’re on the go.
What I DID like about the Seven 22
Obviously the fact it goes to 22 watts is great. Anything above 15 is going to be very useful if you are into RDAs.
More importantly, as I mentioned above, you can fire sub ohm coils on this device. Personally I think this is a super nice feature – it makes it a little safer to sub ohm, and you can really get some nice builds with sub ohm combined with variable wattage, so performance-wise it’s right on track.
The display on this device is also VERY nice. Not only does it show the wattage you have it set at, it also shows you how much battery life you have and what your battery output is. It also shows the ohms of the coil attached, and the voltage output as your vaping. These features all fit on the screen at the same time and basically give you all the information you need to know about your device. Very helpful.
Last, this thing has a really cool feature. To move the wattage up or down, you literally tilt the device to the right or the left. Kind of a Nintendo-Wii style idea. This is the only device I’ve ever seen so far that works like that, and it is pretty cool.
Who is it good for?
The most important thing with this device is you have to be comfortable with the size of it. If you need a high performance device for your desk or your car, and you are OK with the size, then by all means.
The price point is good for a device that goes over 20 watts, but that is going to be changing and already is changing, so while at this exact moment a 22 watt device for around $100 is a good deal, you will be able to get a better deal if you are patient.
Otherwise, it’s mostly good for the novelty of having a ridiculously huge APV.
Where to buy?
I actually bought mine direct from a manufacturer in China a few months ago before they were publicly available, and I paid significantly more than what they are available for now. I recommend picking one up on ebay. Here is a good place to buy one.
Do I use it?
No, I really don’t. I wanted to like this thing but it is just way too big for me. I’m not super anal about appearance, but I literally have no atomizers that I think look good on it, and frankly it’s just too bulky anyway. Performance wise, it is inline with other devices I use on a daily basis, so for me it’s mostly the aesthetics that have kept me away from this one.
The Bottom Line
Quality. There’s really nothing I can say negative about the quality at this point. I haven’t given this thing the rugged, daily use I give some of my more used devices, but I haven’t had any problems to date. Additionally, it has a removable battery so basically the only thing that could possibly malfunction on this device is the button or the circuit board, and I think as long as you don’t bang it around too much or get it wet it should last indefinitely.
Performance. The only real downside with this device compared to other similar devices is that it doesn’t go up to 30 watts. So aside from an 8 watt difference, you will basically get the same level of performance from the Seven 22 as you would from any DNA 30 device. I haven’t had any issues at all in terms of performance and I’ve been testing this in tandem with other DNA30 devices and OKR/T-10 devices.
Ease of Use. As I mentioned above, I really don’t like the fact there is only 1 button. I think moving the device back and forth to control your wattage is cool, but I mostly want to be able to change my settings FASTER, and having to go through multiple screens is an extra hassle. Aside from that, it’s pretty straightforward – put in your battery, screw on your atty, start vaping.
Appearance. Obviously the appearance is the big issue with this device. It’s big, it’s clunky, it’s heavy, it’s awkward. Most importantly, very few atomizers fit on it right now. Even if I had an atomizer that sat flush on it, I have to wonder if it would even look much better anyway. I’m thinking not…
Price. Right now I think this device is priced just about right, around $100. That said, there are DNA devices coming out under that pricepoint that I think are probably better than this thing anyway, so ultimately I see this as more of a sub $50 level device at some point. Basically like an Innokin SVD on crack.
Overall. I was intrigued enough by this thing to actually get in touch with the manufacturer and pay full price plus expensive shipping to get one of these in, but really it just doesn’t work for me. It’s too heavy, too awkward and doesn’t look good. Other than that, it’s great. If you want a big ass piece to sit on your desk all day and chuck clouds, then by all means. Otherwise, I think there are better options out there.
