Jac Vapour S17 Topfill Vape Pen: Review

Here is my review of the Jac Vapour S17 Topfill Vape Pen for beginners.

On the surface, it’s a pocket-sized beginners’ device. But my review of the S17 discovered that there are also a couple of extra plus-points that you usually only see with more expensive models.

The S17 is designed and manufactured by Jac Vapour, a long-standing vape supplier based in Edinburgh, Scotland. See my full review of Jac Vapour here.

Jac Vapour S17 Review: features in detail

Size and shape

Small size is a plus side of the Jac Vapour S17. This is impressive considering its relatively powerful vaping performance.

The Series S17 has an assembled length of just over 13 cm (5 inches). These dimensions mean it’s lightweight, thin and streamlined.

To be honest, it’s quite a “cute” device.  In other words, it lacks the usual clumsy bulkiness of most serious mod devices, and will fit comfortably into any pocket.

Appearance and feel

Appearance of the Jac Vapour S17 is elegant, simple and un-fussy. Out of the box, you can see nice clean lines – and a matt finish (black model only).

The matt black version also feels warm and smooth to the touch.

However, the black finish of the matt model may develop visible scratches after a few weeks. The black model I ordered for this review became a little scuffed around the button area after a month of use.

On the other hand, the stainless steel version has no paint coating, so it’s less vulnerable to scratches as a result. I would choose this model of the vape pen if I ordered again.

Overall, the Jac Vapour S17 is compact and solid looking, and it feels nice to hold, whichever version you choose.

Power review

Battery charge and power storage of the Series s17 is generally good. This is impressive given the very slim battery size.

I managed to charge the device in just over two hours. On that charge, I managed to get about a day of fairly regular use out of the 900 mAh battery before I needed to charge it up again.

I like the coloured LED bars. These light up alongside the power button to show you how much remaining charge you’ve got (green = fully charged; blue = semi-charged; red = recharge now).

The colour-change thing is useful and it adds a bit of novelty, too. After all, who doesn’t like to know how much battery power they have left?

jac vapour s17 power review

The Jac Vapour S17 Vape Pen is a “fixed power” device. This means you only have one power button, so you can’t increase or decrease the power (vapour strength).

This might be a bit annoying if you were expecting to have more control over your vape.

On the other hand, having one power button does make the device super-easy to use. And for absolute beginners, simplicity is a plus point.

Which S17 coil is best for beginners?

Coil lifespan, flavour and vapour production with the S17 are quite impressive.

However, you should know that you get different vapour effects depending on which type of replaceable coil you choose. Jac Vapour supply a wide range of coils, so it’s worth knowing which ones to go for.

a warmer, sharper vape

To be clear, if you like a warmer, sharper-tasting vape, you should go for a 0.5 Ohm MTL S-coils. If on the other hand, you prefer a cooler, milder, fuller-flavoured vapour, you should go for the 1.0Ohm S-coils instead.

Recent ex-smokers probably won’t enjoy the DL coils – these are for “direct to lung” vaping. For this reason, my advice is that you should avoid the DLs for now, and stick with the MTL type.

Cost of S17 coils

Additional coils cost about £10 per pack (you get two with the kit). Based on 1 coil per week usage, you shouldn’t end up getting through more than one pack per month.

For this review, I found I needed to renew my 1.0Ohm coil after about five days – but I am a pretty heavy vaper, truth be told..


Compared to the 5.0Ohm coil, the 1.0Ohm MTL coils seem to give out a lot more flavour. In my tests, they also lasted longer without going stale or dull-tasting.

Best vape juice type for S17 topfill

I would suggest using a thin, PG-based (75% PG and 25% VG) e liquid in the Jac Vapour S17 if you can.


This is because it’s thinner and won’t clog your coils.

All the coils I tested ran for longer and tasted better with PG 70% e liquid, than with a 50-50 PG/VG mix.

Airflow and draw

Airflow control (which allows users to control how hard they suck) is a key feature of the Jac Vapour S17.

The “spinner” located at the base of the tank is for airflow control. It rotates very smoothly to open and close air holes. This design means you can control airflow without accidentally undoing the tank unit.

Am ex-smoker at heart,  I generally prefer some resistance when sucking, so tend to close air holes whenever possible. To this extent, I found the Series-S17 gave me a nice hard draw with air holes fully closed – just like a ciggy!

Is this vape pen easy to use for beginners?

The S17 vape pen has basic controls and features. For this reason, it’s really simple for beginners to start using it right out of the box.

There are only really three working parts that new users need to worry about: battery, tank and coil.

You can put these bits together in a matter of seconds, and with absolutely no expert knowledge or risk of getting anything wrong.

It’s also great that the S17 lets you refill it with e liquid from the top. Removing the cap is a piece of cake, too. You just need a simple screw action to get to the refill tank area.

Thanks to all these beginner features, it has to be said that the S17 is a virtually foolproof beginner vape kit.

JAC Vapour Series S17: weaker points

Tank and battery size

Tank size of the Jac Vapour S17 is a bit meagre at 1.8 ml.

For the purposes of this review, I managed to get about half a day’s regular use out of the freshly-filled S17 tank before it needed a refill. Always carry e liquid with you!

Battery size and performance is great compared to most cheap vape pens. If your only experience of vaping is with regular “garage-bought” e-cigs, you’ll probably be impressed with the S17 charge time and power reserve.

That said, don’t expect the 900 mAh battery to last you much longer than a day before it needs a recharge.

If you want a little more power storage, consider moving up to the Series-B DNA-75 Kit. Alternatively, you could order an extra battery to carry around as a back-up.

No adjustable power

The fixed-charge battery may get you down if you are used to being able to control power and vapour strength.

Again, the JAC Vapour S17 is a transitional ecigarette and so doesn’t really aim to meet the needs of advanced users. This is why it only has the most basic of functions.

On the other hand, if you want a complete e-cig kit that’s simple to use and works right out of the box (they even pre-charge it), the Jac Vapour S17 may be just what you are looking for.

Noisy 0.5 Ohm coils

Personally, I found that the “hotter” (0.5Ohms) coils were a bit too hot – and noisy – for my liking.  I prefer a cooler vape anyway, but I’m really not a fan of that raspy coil sound you get when you hit the power button.

For this reason, I would go for the 1.0 MTL coils rather than the 0.5 Ohm ones.

Hopefully, you should find they’ll last longer, taste better and give you a much quieter vape.

Use PG E Liquids for best results

Heavy (VG-based) e liquids tend to be sluggish in the S17. For this reason, try to avoid 100% VG e liquids, and stick to either PG or 25/75 VG/PG e liquid mixes, instead.

Jac Vapour S17 Review: round-up

If I was a brand-new vaper all over again, I’d be impressed by the Jac Vapour Series S17. As I’ve made clear in this review, it’s a great little vape pen to start with, and it’s got everything you could want in a first vape.


Thanks to its well-thought out design, the S17 looks good. It’s really easy to use for complete beginners, and it gives you better quality and more features than your average off-the-shelf vape pen.

However, if you do go for the S17, make sure to choose a thin e-liquid (vape juice) with your kit. Secondly, don’t expect miracles with the battery power and charge.

After all, the S17 is a just vape pen, not the Series-B DNA mod.
