SKE Crystal is a line of vaping devices known for their eye-catching “crystal-finish” design. This look is a big part of what makes them stand out. It's not just about appearance; these products use flavour enhancing mesh coils. From my experience, mesh coils are good for producing a decent amount of vapour and giving a clear vibrant taste of the e-liquid.
The SKE brand is owned by Shenzhen SKE Technology Co., LTD, a company that started in Shenzhen, China[i]. Even though they haven’t been around for a huge amount of time, they’ve grown quickly and now sell in over 50 countries, including places like Ireland, the UK, and the USA.

The Original SKE Crystal Bar
SKE first became really well-known because of their disposable vapes with the original Crystal Bar being a big hit and a key part of their early success. This popularity with disposables helped them move into other types of vape products.
That original SKE Crystal Bar disposable was a popular choice for many vapers because it was easy to use and had good icy flavours. But rules are changing, and these single-use vapes, including the Crystal Bar, are now banned[ii].
Rechargeable SKE Crystal Vapes
Because things are changing in vaping, with the disposable vape ban now in place, SKE has started to offer more than just single use vapes. More and more people are looking for vapes that last longer, are better for the environment, and save money in the long run. To counter this, SKE has brought out rechargeable kits and pod vape with the SKE Pro 600 and SKE Crystal 4 in 1, which I've been trying out, are part of this move. They aim to give you the SKE flavours and easy-to-use design people like, but in a vape you can use again and again.

SKE Pro 600

The SKE 600 PRO Kit looks a lot like the original Crystal Bar, but the big difference is that it’s a reusable vape device. It’s small and light, so it’s very easy to carry around. Being pocket-friendly is a key feature of this one.
The device has a built-in 400mAh battery that you can recharge. It uses a USB-C fast charge connection and recharges in under an hour. It also includes an LED indicator that flashes when the battery is low I found the battery size works well with the 2ml pre-filled pods. These SKE 600 PRO pods have a 20mg/ml (2.0%) nicotine strength and use nic salts, which usually means a smoother vape. Each pod delivers up to 600 puffs. The kit comes with one SKE 600 PRO Battery and one SKE 600 PRO Pod. Please note: A USB-C charging cable is not included and must be purchased separately.

Operation is effortless. With no buttons to press, you simply inhale to activate the device. You just put in an SKE 600 PRO pod, and it's ready. The device provides a Mouth-to-Lung (MTL) draw that closely mimics the sensation of a traditional cigarette, making it an excellent choice for those transitioning from smoking.
SKE 600 Pro Pre-filled Pods

When it comes to flavours, SKE Pro uses the popular SKE Crystal Bar flavours. There’s a wide choice, including well-known ones like Berry Ice, Blueberry Sour Raspberry, and Lemon & Lime. The pods have a 1.1ohm mesh coil inside, which helps make sure the flavours is good and lasts until the pod is empty.
I'd say the SKE 600 PRO is a great option if you're new to vaping, want something easy to use after disposables, or just need a reliable, simple backup vape. Its main plus points are that it's easy, portable, and performs consistently, giving you those SKE Crystal disposable tastes in a reusable kit.
SKE Crystal 4 in 1

The SKE Crystal 4 in 1 pod kit is a bit more unusual with its multi-pod setup due to it holding four 2ml prefilled pods at the same time in. This means you can have up to 8ml of e-liquid in total. Each of these Crystal 4 in 1 pods has a 2% (20mg/ml) nicotine strength and should give up to 600 puffs, using a 1.1ohm mesh coil for better flavour. So, with all four pods, you could get up to 2400 puffs.
Its standout feature is the rotating part: to change flavour, you twist the side pod compartment until it clicks. As a welcome addition, a small window clearly displays the currently selected flavour. To power this, it has a larger 950mAh battery that’s rechargeable and reusable, with an 11W output. This also charges with a USB-C cable but, like the SKE PRO, the cable isn’t included with the kit. The kit includes one SKE Crystal 4 in 1 Pod Kit and four SKE Crystal 4 in 1 Pods. It's also inhale-activated and designed for MTL vapers.

While having four flavours ready to go is handy, the device is “slightly bulkier than a standard pen-style vape”. This is a clear difference from the very small Pro 600 and something to think about if you need it to be really small.
SKE Crystal 4 in 1 Pre-filled Pod Editions

The flavours, from the 1.1ohm mesh coils, is generally good. Choose between pre-selected, multi-flavour ‘Editions’ or packs of a single flavour. Go for a variety pack like the Blue Edition or Green Edition, or grab a classic like Cherry Ice. The only downside is that you can't easily see the e-liquid level because the pods are black. This makes it hard to know when a pod is nearly empty, and can lead to an unexpected burnt taste.
The SKE Crystal 4 in 1 is a vape for people who want to vape for longer and switch flavours easily. Its TPD-compliant multi-pod system is a smart way to offer more e-liquid capacity, like having four disposables in one, which is better for waste.
SKE Pro 600 vs. SKE Crystal 4 in 1
After trying both, here's how I see them stacking up:
- Portability: The SKE 600 PRO is definitely better here. Its “pocket-sized, lightweight” design I mentioned earlier makes it much smaller and easier to carry than the “bulkier” Crystal 4 in 1.
- Battery and Puff Count: The Crystal 4 in 1 holds more power with its 950mAh battery and gives more puffs overall - up to 2400 from four pods. The 600 PRO combines a 400mAh battery with a 600-puff pod, delivering balanced and efficient performance in a compact vape.
- Flavour Variety: The Crystal 4 in 1 is the clear choice if you like lots of flavours ready to go, because of its rotating system and the multi-flavour editions available. The 600 PRO is a single-flavour vape per pod.
- Ease of Use: Both are easy to use as they are inhale-activated. The 600 PRO is as simple as it gets with “zero setup”. The Crystal 4 in 1, while also not complicated (take off the mouthpiece, put in the pods, twist the mouthpiece to lock, then twist to change pods), does have those extra steps for setup and flavour switching.
- User Experience: The 600 PRO gives a steady and “tighter MTL draw”. The Crystal 4 in 1, though it has new ideas, has some downsides like not being able to see the liquid in its black pods (which can cause burnt tastes).
If you want something really simple, with a good MTL feel, that's easy to carry for one flavour, the SKE 600 PRO is the more polished and reliable pick. If you want to vape for longer and be able to switch between different flavours easily, and you don't mind a bigger vape, the Crystal 4 in 1 has some unique plus points.
SKE Crystal TPD Compliance
Both the SKE 600 PRO and Crystal 4 in 1 are TPD-compliant[iii]. This means they follow UK rules for things like e-liquid capacity (2ml per pod) and nicotine strength (no more than 20mg/ml). These vapes use pre-filled pods that you don’t need to refill. Just replace the entire pod when it runs out. Buying from well-known sellers like Totally Wicked is important to make sure you get genuine products and avoid fakes, which can be unsafe. Always check for official packaging, batch numbers, and codes that show it’s authentic.
SKE has made a smart move by offering rechargeable pod systems. It's what many vapers are looking for now: a way to vape that's better for the planet and their wallet over time, without losing the ease of use and flavours they liked in disposables.
