JAC Vapour Series B DNA75W

JAC Vapour is renowned for making good products from high-quality materials. The original Series B DNA75 was released at a time when 22mm atomizers where all the rage and it was an excellent and popular device. So it’s no surprise that they have decided to tweak the design to enable the use of up to 25mm atomizers – now there are so many on the market.

Have they managed to keep the same quality design, form factor, and performance?

The Good

Excellent build quality with one of the best chipsets on the market, capable of fitting 25mm atomizers.

The Bad

Not much really, it may be a little pricey for some due to having a DNA75 chip.

The Bottom Line

One of the best crafted single 18650 mods on the market. Yes, it is a little pricey, but you get excellent build quality and performance, and it looks and feels exquisite.

1Design & Build Quality

As expected the new SERIES-B DNA 75 comes in packaging that is worthy of carrying such a premium device. JAC Vapour is also one of the few companies that make sure there’s a comprehensive and detailed user manual included, which is great because the DNA boards are not the most intuitive or easy to navigate for newer vapers.

The first thing that strikes you when your lay eyes on the new Sandstorm SERIES-B DNA 75 is just how premium it actually looks. The brushed metal finish is akin to that of an Apple MacBook….and it almost screams quality at you before you place it in your hand.

Once you do pick up the device, it gets even more impressive.

The finish is silky smooth to the touch, but not in the slightest slippery. It has a weight to it that only premium materials can give you, and it’s that reassuring kind of weight.

The only sights of plastic on an otherwise minimalistic sleek device come in the form of the fire and + & – buttons. In fact, they are not just your standard plastic; they are Polycarbonate +ABS with a rubber oil finish, which helps maintain the matt quality finish.

The fire button is my only slight negative about the design of the device. It is an excellent fire button and is positioned in the perfect place and feels great to touch. However, it does require the most feather-light of touches to trigger it. Some may see this as a positive, but I’d prefer a little less sensitivity.

The battery compartment is curved to sit perfectly in the palm of your hand and has two little notches in the center to remove it from the device. It does take a bit of a pull, due to the super strong magnets but that’s a good thing as it means it will almost certainly not fall off accidentally. The tolerances are spot on, and there’s absolutely no play or movement with the door when it’s on the device.

Inside the battery compartment, there’s no battery ribbon, but it is simple enough to remove the single 18650. You may need to be a little careful when placing it back in to ensure you don’t damage the wrap as it is a little tight in there. But I find pushing the battery down on the negative pin makes it a lot easier.

The screen of the device is also uncluttered showing all the right amount of info your battery level, resistance, voltage, amps and the temp or wattage reading.

At this stage, everything with the design and form factor is almost identical to its predecessor, bar the materials used. However, the one big and important change comes with the 510 and the plate that your atomizer sits on. JAC Vapour decided to not make the whole device larger in order to incorporate a larger tank. Instead, they kept the same slim profile and just made the top and base curve out to a wider point. It’s done so well, that I think it really complements the design by giving it these smooth proportional accents.

I actually think the new SERIES-B DNA 75 is not only better looking than the older version. I think it is one of the best looking and feeling devices on the market, especially in the single 18650 category.

I’ve been gushing over this thing since I got my hands on it, and it’s going to take a full army to prise it away from me.

3Features & Performance

I won’t go into detail on how to use the DNA75 chip, as not only are their tons of tutorials out there, but JAC Vapour also does an excellent job of detailing it in the manual.

As I said before, it is not the most intuitive to use, but it is certainly one of the best performing. In both wattage and temp control mode, the Evolv boards are spot on, it’s clear to see why they are so popular and it is the perfect fit for JAC Vapour’s devices.

The ramp up time when firing is pretty much instant, and it can handle extremely low builds. I love to use the DNA’s in temp control mode, and in my opinion, it is the smoothest experience out there.

However, this is not the latest DNA board, so adjusting any TCR values will have to be done using the Escribe software. But for most users, it’s absolutely fine out of the box with all the presets for the popular materials. I’m sure knowing JAC Vapour, they will have an update in the pipeline that will come with the newer DNA 75C chip.

Battery efficiency is something that some had a question mark over on the DNA75, as supposedly the other chips were more efficient, but for me using Sony VTC5A’s, there was no issue whatsoever. Using the device continually at 50W I was getting about 8 hours use.

Remember also; this is a single 18650 device so is obviously only capable of firing up to 75 watts.

You’d be hard pushed to find a better performing single 18650 device, especially one that looks and feels this good.

  • Stunning design
  • Excellent build quality
  • Compact & Study
  • DNA75 chip
  • Great performance in all modes


  • A little pricey
  • Only one color choice
  • Slightly sensitive fire button (subjective)

It’s not hard to be a JAC Vapour fan, especially when there are so many devices being released from China with sub-par build quality. It’s refreshing to see a company that knows where they sit in the market and makes sure that every device they release fits that mould.

The new SERIES-B DNA 75 is a beautiful device, which performs excellently and is a joy to use. JAC Vapour didn’t try to reinvent the wheel; they took wise design choices to tweak an already great device.

Yes, it only currently comes in the Sandstorm color, but I’m sure we will see them release a black version, and I’m almost certain down the line they will incorporate the DNA75C color chip from Evolv also.

Some might think it’s a bit on the pricey side for a single 18650 device, but when you factor in that they use a DNA board and such premium materials – I think it’s great value.

The SERIES-B DNA 75 is without a doubt my favorite single 18650 device currently on the market.
