SKE Crystal 4in1 Vape Review | Innovation At It’s Best!

Callumn WinterPod Vapes Leave a Comment

Once in a while a vape passes across our desk that truly innovates, changing the way we vape and how we enjoy e-juice flavors. The Crystal 4in1 we’re looking at today is one such device!

For the first time ever (as far as I know), vapers can simultaneously enjoy 4 different flavors without the need to change between pods. In answer to recent calls to ban disposable vapes, SKE have developed a reusable and rechargeable pod device that accepts four 2ml disposable pods, each with a different flavor!

What the Crystal 4in1 aims to do is give users the convenience of vaping a disposable while limiting the amount of disposable waste thrown away at the end. The Crystal 4in1 is a pod device with an internal rechargeable battery meaning you recharge and reuse the device while only disposing of the 4 small closed flavor pods.

You can then replace these 4 pods with any mix of flavors from the range. Where things get really interesting is the ability to switch between the 4 different flavors in the ‘cartridge’ with just the flick of a thumb!

This also means vapers living within a territory governed by the TPD (a law restricting users to a 2ml device) can now enjoy the convenience of vaping 8ml of e-juice (4 X 2ml) at any one time. Being from the UK myself I can’t overstate how useful this is!

Going from a 2ml disposable or pod vape to what essentially amounts to an 8ml ‘pod’ takes away so much of the hassle of refilling or replacing the e-juice and/or pods. On top of that the Crystal 4in1 features a 950mAh rechargeable battery and a mesh coil for increased flavor and vapor delivery!

But that’s enough of an introduction! Read on to find out how well the Crystal 4in1 performed!

What’s in the Box?


SKE Crystal 4in1 - What's in the Box?

The SKE Crystal 4in1 comes packaged in a small square box with plenty of information for the user. The color of the box matches the color of the device inside, which also corresponds with the type of flavors included.

For example, the Rose Edition (pink box) features 4 flavors that all have red/pink fruits in common; Fizzy Cherry, White Peach Razz, Cherry Ice and Strawberry Burst.

On the front of the box you’ll find a picture of the device along with the name, number of puffs, nicotine level and flavors inside. There’s also a large mandatory nicotine warning on the bottom third of the front.

On either side of the packaging you’ll see a ton of information including a list of key features, expiry date and contact information for SKE. There’s also a handy QR code that lets you check the Crystal 4in1 you’ve purchased is the real deal.

SKE Crystal 4in1 - Packaging contents

Inside the box you’ll find your Crystal 4in1 Pod contained inside a foil wrapper and the four included flavor pods, each sealed individually inside a small plastic carton. There’s also a handy user manual that tells you how to setup the Crystal 4in1 (don’t worry we’ll cover that in the next section!).

SKE Crystal 4in1 | Design and Appearance


In terms of size the Crystal 4in1 measures 80mm in height, 54mm in width and 30mm in depth, making it a reasonably compact device. It easily fits in the palm of a hand and the ‘keyhole’ shape means it ticks all the right boxes in terms of ergonomics.

The Polycarbonate construction also means it’s incredibly lightweight, weighing in at a mere 70g. This makes it an ideal device for taking with you on the go! In fact, I regularly carried around 2 or 3 of the Crystal 4in1s in my pocket without feeling weighed down or inconvenienced.

And despite the slight size and light weight, the Crystal 4in1 still feels sturdy enough to stand up to the rigors of daily life. On at least one occasion I dropped the Crystal 4in1 I was vaping with zero damage visible after the fact. More importantly, the performance remained just as good as when I’d first taken it out of the box!

SKE Crystal 4in1 - Design and Appearance 1

Without a doubt though, the standout feature for me is the innovative ‘4in1’ pod system. Essentially the Crystal 4in1 has a cartridge that holds up to 8ml of e-juice (four 2ml closed pods). More impressive is the fact you can switch between the four different pods by turning the cartridge clockwise or counter-clockwise with just a flick of your thumb.

When you first get the Crystal 4in1 out of the box the cartridge is empty and you have to remove each of the 2ml pods from their individual wrappers.

SKE Crystal 4in1 - Design and Appearance 2

On the top of the Crystal 4in1’s body you’ll then see two padlock symbols; one is open to represent the unlocked position and the other is locked to represent the closed position.

By gripping the removable mouthpiece section you can then turn it from the locked position to the unlocked position. With a light pull the mouthpiece section then comes away from the rest of the body to reveal the empty cartridge.

SKE Crystal 4in1 - Design and Appearance 5

Once inside you’ll see the cartridge is divided into four smaller segments that each house one of the 2ml pods that come with the device. Inserting the pods is straightforward and it’s easy to identify which way round the pods are inserted by a small chimney on the top end of each pod.

SKE Crystal 4in1 - Design and Appearance 6

The chimney on each of the pods then aligns with the four holes in the removeable mouthpiece section. Once all four pods are inserted you can line up the mouthpiece section with the unlocked padlock symbol and simply turn it clockwise so the mouthpiece is again locked in place.

After this you’re ready to start vaping! All in all the process takes less than a minute and is incredibly straightforward and user friendly!

SKE have also made it super easy to know which of the four pods you’re vaping on by including the flavor name written along the length of the pod’s body. As you turn the cartridge wheel to select the flavor you want to vape, you’ll see the name of the flavor align with the clear protruding mouthpiece at the top.

Turning the cartridge is also super easy because of grooves on the outside of the cartridge body. It takes no effort at all to turn the cartridge and it clicks into place with a satisfying clunk when the selected pod is lined up with the mouthpiece.

SKE Crystal 4in1 - Design and Appearance 8

Overall the design is incredibly effective and works really well. Setting up the device takes no time at all and switching between the four installed pods is effortless. Like I mentioned earlier, this innovative design means people living in a country governed by the TPD are no longer restricted to a 2ml device!

Heck, even if you’re not living in a TPD country the ability to effortlessly switch between four different flavors on the go is incredible!

On top of this the SKE Crystal 4in1 also looks fantastic! There’s a clear outer shell that lets you see the internal color coded cartridge and the 18350 battery underneath. Branding is also stylish with “SKE Crystal 4in1” written in bold white font across the front.

For such a small battery the 950mAh capacity is also impressive and allows for plenty of vaping time in between charges. As a heavy vaper I expected to get around a day’s worth of vaping from the Crystal 4in1 but I was pleasantly surprised when each charge gave me almost two full days of vaping time!

The SKE Crystal 4in1 also comes in a choice of six different colors, with each color corresponding with the kind of flavors included. We’ll cover the 6 colors and the included flavors a little further on.

On the bottom of the device you’ll find the Type-C USB charge port for when it comes time to recharge the device. There are also two small pin holes located on the bottom; one for the airflow and another for the LED puff indicator.

Whenever you draw on the device the puff indicator lights up white and also flashes 10 times in quick succession when the battery runs out. The other small pin hole on the bottom allows for a reasonably tight mouth-to-lung (MTL) draw that nicely replicates the feeling of smoking on a traditional cigarette.

Now in case you couldn’t already tell, I really love the design and appearance of the Crystal 4in1! But…..sadly it’s not all rainbows and butterflies.

For vapers who enjoy adjusting settings they may find the Crystal 4in1 slightly lacking. It’s a fixed wattage device and the airflow is also non-adjustable. As an auto-draw device there’s also no fire button and it’s impossible to know how much charge is left in the battery due to the absence of an LED display.

While the LED puff indicator on the bottom does a good job of letting you know when the battery is empty, there’s no change in color prior to it running out to warn you of low battery.

SKE Crystal 4in1 - Design and Appearance 11

With that being said, personally I think the Crystal 4in1’s simplicity and user-friendly design is where it really shines. I’ve vaped Mods and Pods in the past that can do everything but turn on the TV! And while they’re great and certainly have their own merits, sometimes it’s nice to use a simple device and let your brain switch off!

Overall I was incredibly impressed with the design on the Crystal 4in1 and I wouldn’t be at all surprised if we start seeing other companies follow suit with similar designs in the near future!

SKE Crystal 4in1 | Performance


When it comes to performance the SKE Crystal 4in1 also does a truly admirable job!

The first thing that really struck me was the excellent lifespan of the non-removable 18350 battery. Considering the slight size, the 950mAh capacity is great and should be enough to last the average vaper well over two days of vaping before it needs a recharge.

As a heavy vaper I expected around a day of vaping before the battery ran dry and couldn’t quite believe it when this dinky device kept on providing vapor for two full days! The LED indicator on the bottom also gives a good indication of when it’s time to recharge by flashing ten times in quick succession. You’ll also notice a very slight drop-off in vapor production near the end of each charge.

SKE Crystal 4in1 - Performance 1

After plugging in a USB-C cable (not included) the LED stays permanently lit red. Again there’s no color change midway to indicate the Crystal 4in1 is getting closer to full charge but once it does reach full capacity the LED remains permanently lit white.

All told a recharge takes a little under 90 minutes which is to be expected for a battery rated at 950mAh. A big bonus however is the inclusion of ‘pass-through’ charging meaning you can still puff on the 4in1 while it’s charging.

As well as the excellent battery life the longevity of the 4 pods is also great. True to the words on the box, the Crystal 4in1 provides approximately 2400 puffs across the 4 included pods. As a long time user of 600 puff disposables I know 2ml of e-juice typically gets me around a full day of vaping, give or take a little depending on the particular disposable.

SKE Crystal 4in1 - Performance 2

Again though the Crystal 4in1 exceeded all expectations and provided just over 5 full days of vaping! Whether this is down to the performance of the mesh coil included with each pod, or whether you get slightly more out of 2ml when you’re not constantly vaping on the same coil is hard to tell.

Regardless though, 5 full days of vaping is excellent and represents great value for money (more on this later). The excellent lifespan of the battery and included pods makes the Crystal 4in1 not only super cost effective but also incredibly convenient.

SKE Crystal 4in1 - Performance 3

Another thing that impressed was the decent amount of vapor it kicks out. Taking just short second-long puffs results in a surprisingly good amount of the white stuff. A longer draw of several seconds then kicks out a really satisfying amount that easily rivals most of the disposables I’ve tried in the past.

In terms of throat hit and nicotine delivery it also ticks all the right boxes. As a TPD regulated device the e-juice is restricted to a strength of 20mg/ml but this was more than enough to stem any cravings and it still provided a decent throat kick to boot!

The auto-draw function also worked brilliantly across all of the Crystal 4in1s I tested. The response is super sensitive and it only takes the lightest of puffs to activate.

The draw on the Crystal 4in1 is also setup for a reasonably tight MTL inhale and the oval shaped mouthpiece nicely compliments this puff style. While it is a shame there’s no option for adjustable airflow, I found the MTL draw was just tight enough and nicely mimics the draw on a traditional cigarette.

This also means the Cystal 4in1 would work great as a stepping stone for smokers looking to make the switch to vaping!

SKE Crystal 4in1 - Performance 4

It’s also worth noting not a single of the Crystal 4in1s I tested leaked, not so much as a single drop. Vapes have come on leaps and bounds in recent years and this problem is thankfully fairly rare, with most of the products we now test being leakproof.

Unfortunately though it’s not a complete thing of the past and the fact the 4in1 seems completely leakproof is another definite bonus!

For those of you with OCD however you will notice a build up of e-juice that sits just under the clear, see-through mouthpiece. While it does nothing to affect the actual performance I must admit it slightly bothered me and gives the mouthpiece a slightly used, dirty look after a short time of use.

SKE Crystal 4in1 - Performance 5

This minor negative however pales in comparison to the major advantage posed by the rotating 4in1 cartridge. It wasn’t until I’d first started using the Crystal 4in1 that it truly hit me how awesome it is to be able to seamlessly switch between four different flavors at a moments notice.

The cartridge rotation remains smooth and I can’t overstate how simple it is to switch between the four installed pods!

Overall I was incredibly impressed with the Crystal 4in1 performance! Not only does it offer great battery life and excellent vapor production but the longevity of the four installed pods really surprised me! On top of that the nicotine delivery and throat hit are great and the MTL draw was spot on!

SKE Crystal 4in1 | Flavors

Another compelling reason to choose the Crystal 4in1 as your pod of choice is the delicious and diverse flavors to choose from!

In total there are 16 flavors to choose from and as you can see from the list below there are some really great blends in the mix:

  • Watermelon Ice
  • Pink Lemonade
  • Watermelon Strawberry
  • Melon Berry
  • Blueberry Sour Raspberry
  • Blueberry Raspberries
  • Cola Ice
  • Blueberry Peach
  • Lemon & Lime
  • Tropical Mixed
  • Blueberry Lime
  • Lychee Ice
  • Cherry Ice
  • Fizzy Cherry
  • Strawberry Burst
  • White Peach Razz

What I will say however is that the vast majority of flavors in the range are fruity blends. Now while this isn’t a problem for me (fruit flavors are my go to), I could see lovers of tobacco, dessert and candy flavors feeling a little ‘left out in the cold’.

Nevertheless I think we can all agree that fruity blends are the most popular kinds of flavors and SKE have done a really fantastic job of producing authentic, mouth-watering e-juices!

We were lucky enough to receive three of the editions (colors) out of a possible six, which featured 12 of the possible 16 flavors between them. While taste is incredibly subjective I’ll do my best to give a brief description of each flavor below:

SKE Crystal 4in1 – Blue Edition


SKE Crystal 4in1 - Blue edition

Blueberry Sour Raspberry –

A delicious blend of tart blueberry on the inhale with a slightly sweeter raspberry note really coming through on the exhale. A really rich taste with authentic fruity flavors!

Blueberry Raspberries –

Very similar to the previous flavor but with less sour notes and a much sweeter vibe! Again the fruits are really easy to pick out and taste authentic and rich.

Cola Ice –

My personal favorite from the ‘Blue Edition’, the Cola Ice is one of the best cola flavors I’ve ever tried! The ice also adds a really refreshing vibe but isn’t so strong that it overpowers the cola. Easily an all-day vape for me and one I found hard to stop puffing on!

Blueberry Peach –

A really delicate blend that’s perfect for a hot summers day. The blueberry and peach flavors work perfectly together to create a really mouth-watering e-juice.

SKE Crystal 4in1 – White Edition


SKE Crystal 4in1 - White edition

Watermelon Ice –

A real juicy, mouth-watering watermelon flavor with a delicate hint of ice that rounds the flavor off nicely. Again hats off to SKE for creating a really authentic taste! From the very first puff it feels like you’re biting into a juicy chunk of watermelon.

Pink Lemonade –

A really refreshing flavor, the Pink Lemonade is another one that’s perfect for a sunny day spent outside. The fizz factor from the lemonade was excellent and really keeps you coming back for more!

Watermelon Strawberry –

Similar to the Watermelon Ice, this one combines the juicy, refreshing taste of the watermelon with the sweetness of the strawberry. Yet again another all-day vape for me and one I hope to sample again soon.

Melon Berry –

A delicious blend of succulent and yummy fruits that dance on the tastebuds! Again I was impressed with just how refreshing this blend is and how much it kept me coming back for more.

SKE Crystal 4in1 – Rose Edition


SKE Crystal 4in1 - Rose Edition

Fizzy Cherry –

Out of the 12 flavors I tried in total the Fizzy Cherry has to be my absolute favorite! The fizz factor combined with the rich and authentic cherry flavor creates a really satisfying flavor that really works well. Another all-day vape for me and one I was disappointed to see run dry!

White Peach Razz –

A really sweet blend with just the right amount of sugary goodness to keep your lips smacking! For me the juicy peach flavor was much more prominent with the raspberry flavor working to add a nice sweetness to the blend.

Cherry Ice –

Again SKE have really nailed the cherry flavor. I’d go so far as to say it’s the most authentic cherry I’ve ever sampled in an e-juice! I was also impressed with the level of ice again. So often I find the ice overpowers the other flavors and spoils a vape but SKE have really nailed the perfect balance.

Strawberry Burst –

Just like the name suggests this one absolutely bursts with flavor! An explosion of sweet and succulent strawberry that dances on the tastebuds!


Having sampled 12 of the available 16 flavors I can’t wait to try the remaining 4 in the range! Each of the 12 I tried were rich in flavor and blended just perfectly. As ever the SKE flavors continue to be a standout feature and a key reason to try their Crystal 4in1.

SKE Crystal 4in1 | Price


At the time of writing several online stores are stocking the Crystal 4in1 for the incredibly low price of £11.99!

When you factor in the increased amount of e-juice (for those in a TPD region) and the convenience this offers, £11.99 is a really great price! On top of that the incredible flavors and the excellent performance mean I’d happy pay more than this for one!

It’s also worth mentioning again that as a heavy vaper each of the Crystal 4in1s lasted me around 5 full days. At this kind of price the SKE Crystal 4in1 pales in comparison to the price you’d pay for cigarettes or even single day disposables like the popular 600 puff Elf Bar.

SKE Crystal 4in1 | Verdict


Overall I was incredibly impressed with the SKE Crystal 4in1. The standout feature for me was the ability to seamlessly switch between 4 different flavors on the go! But even forgetting that amazing innovation, the Crystal 4in1 offers fantastic flavors and great performance for a really reasonable price!
