STLTH 3K Disposable Device Unboxing + Review

STLTH doesn’t just make incredible pod systems—they also offer a range of disposable vape devices that aim to bring customers the same convenience and quality the brand is widely known for. The STLTH 3K disposable vape device is designed to eliminate the need for swapping coils, refills, and the other little maintenance tasks that come with reusable devices so you can spend more time vaping to your heart’s content.

Our team is here to show you how the STLTH 3K stacks up to their pod systems and whether it competes with disposable devices from other popular brands. Follow along with our unboxing and review below so you can make an informed decision about whether or not to try this product for yourself.

Key Features of the STLTH 3K Disposable Device

The STLTH 3K offers:

  • Up to 3000 puffs
  • A direct draw firing mechanism
  • 6ml of e-liquid
  • An integrated mesh coil
  • An integrated 800mAh battery

It’s also recyclable, which makes responsibly getting rid of your device easy after you’ve exhausted it. All well and good—now let’s get into what it’s like to use this thing!

First Impressions of the STLTH 3K Disposable Device

One thing you’ll notice the moment you take the 3K out of its packaging is that it doesn’t feel like other disposable devices. For one thing, it’s quite a bit heavier than your typical e-cig—and then there’s that metal finish on the body, which makes the 3K seem like a much higher-end device than most comparable products. The mouthpiece and bottom are both plastic, but it’s a sturdy, robust type that doesn’t feel cheap or fragile.

Of course, since this is a disposable device, there’s no charger and no place to connect one. Instead, the bottom sports a small air hole—there’s another one on the side, where a pod system might have a screen or controls.

This whole package fits together exceptionally well; there are no gaps between the ends and body, and everything feels tightly arranged. This inspires plenty of confidence before you even fire the device up for the first time.

Using the STLTH 3K

The 3K is ready to go right out of the box, so you don’t need to worry about charging it up or filling it with e-liquid. It’ll activate the first time you take a draw (and since it’s draw-activated, you’ll only drain the battery while you’re using it—no need to worry about the power running out before your juice does).

Flavour Profile & Strength

There are 12 different flavours available for the 3K, including:

  • Flavourless
  • Tobacco
  • Tropical Punch
  • Watermelon Honeydew
  • Green Apple Ice
  • Grape Punch
  • Lemon Ice
  • Mint
  • Blue Raspberry
  • Peach Ice
  • Strawberry Kiwi Ice
  • Banana Ice

We tested the Tropical Punch device and found the flavour to be surprisingly smooth and consistent. It’s also a bit on the strong side (which you’ll probably love, but be forewarned). You’ll notice that there’s quite a bit of a menthol hit as well, which you’ll feel in the back of the throat. If that’s too much for you, try the tobacco or flavourless options.

Draw Quality

Long draws on the 3K will produce a stronger throat hit—so because this is already quite a flavourful device, you may want to opt for a less-is-more approach. We found the draw quality best when using moderate suction and keeping puffs relatively short.


The STLTH 3K is designed for 3000 puffs, and we’re happy to report that we didn’t experience any problems with the 800mAh battery or flavour during the week or so that we used ours. Having the vape perform and the flavour stay strong right up until the end of the device’s lifespan is a pretty big plus.

Is the STLTH 3K a Good Buy?

When it comes to value, you’re going to get a lot of different opinions on disposable devices. While some people think buying a device that isn’t meant for long-term use is silly, we tend to think disposable vapes are useful for people who like to switch up their vaping experience periodically without having to invest in multiple pod or tank systems.

The 3K costs less than the Geek Bar B5000 series, but it’s not really supposed to compete with them (the STLTH 5K would be a much fairer comparison there). These models are just a little less expensive than the Vice 2500 and offer slightly longer expected usage (although the battery on the 2500 is 200mAh larger).

Final Thoughts on the STLTH 3K Device

The STLTH 5K is a smartly-designed disposable vape for users who want a high-quality experience from a convenient product. The little extra touches like the battery and e-liquid indicator lights enhance its usability by giving you plenty of warning before you reach the end of its lifespan—it’s this kind of focus on user experience that makes STLTH so good at what they do.

The STLTH 3K is a convenient, well-made disposable device that offers excellent portability and flavourful, straightforward vaping. It’s no-frills, but that doesn’t matter when you’re looking for an affordable way to deliver the goods—and that’s what you get here. Personally, we think it’s better to do a simple thing well than try and fail at a bunch of complicated ones.

Frequently Asked Questions

Why can’t I recharge my STLTH 3K?

No; the STLTH 3K is designed to last for 3000 puffs without needing to be recharged. You should run out of e-liquid before you run out of battery power.

Can I refill the STLTH 3K once the e-liquid runs out?

No, the STLTH 3K is a disposable device and is not meant to be refilled. Once you've used up the e-liquid or battery, the device should be responsibly recycled.

How can I properly dispose of my STLTH 3K?

You can either take your STLTH 3K to a local recycling centre or mail empty devices back to STLTH for responsible disassembly and recycling. To do this:

  • Message with your full name, phone number, and mailing address.
  • STLTH will send you a prepaid return envelope you can place the devices in and mail back.
  • Please wait until you have at least 10 empty devices before sending them back, as this makes shipping more efficient and environmentally friendly.

3K devices cannot be placed in the brand’s pod disposal bins available in some brick-and-mortar vape shops. Please follow the steps above to get rid of yours responsibly.

Can I change the flavour strength of my STLTH 3K?

While the 3K does not have output controls or swappable coils, you can adjust the flavour strength by changing the amount of effort you put into each draw. Lighter draws will result in a gentler flavour profile with less throat hit. Avoid drawing too hard on your device, however, as this can cause e-liquid to move through the mouthpiece before it has had a chance to fully vaporize.
