Caliburn A2 Starter Bundle

Caliburn Device Kit+ (2) 30ml Salts + Mystery Flavor



Our Caliburn A2 Starter Bundle includes the following:

  • Uwell Caliburn A2 device
  • USB-C charging cable
  • (2) Caliburn A2 Pods
  • (2) 30 mL nic salt flavors
  • 30 mL Mystery Flavor

DISCLAIMER: This bundle only includes 2 individual pods with the device kit. If you would like more pods, you will need to add additional pod packs with the optional dropdown box. We recommend the new 1.2 ohm pods as they are more user friendly and better at preventing leaking. 

The Caliburn A2 Starter Bundle is a no brainer. It comes with everything you need out of the box to start vaping on the new Caliburn A2. That includes the device itself, a USB-C charging cable, two 30 mL bottles of your favorite Handcrafted Salt flavors and a bonus 15 mL mystery flavor.

So, you're essentially getting the Caliburn A2 device for FREE when you add up the value of the other items! You won't find a deal like this anywhere. Plus, our nic salts are optimized for Caliburn pods. They'll last up to 3-4 times longer than with most overly sweetened commercial e-liquids.

    User Manual

    What's new on the Caliburn A2?

    More Power

    The Caliburn A2 uses approximately 30% more power than the original Caliburn. This makes it produce more vapor per hit so you might feel like the nicotine level you're used to is too high.

    I recommend cutting your nicotine level down if you feel like you're getting too much nicotine too fast. It was a bit of an adjustment period for me, but I was able to stick at my same nicotine level and I just take slightly shorter hits and vape a little less frequently than I did with the original.

    Faster juice consumption

    You're going to go through the juice in the pod a lot quicker! This is especially true if you are using a nicotine strength that is too low for your tolerance level. Make sure you get into the habit of glancing at your fill window so that you get a feel for how often you need to refill your pod.

    Faster charging

    The A2 charges much faster than the original Caliburn. So if you can spare a few minutes to toss it on a USB charger, it'll go a long way. Half an hour on the charger is all you need for a full charge. Five minutes is equal to nearly 20% of a charge.

    Improved LED indicator

    The LED battery indicator thresholds have changed. (Full details in the manual.) On the original Caliburn, the LED would turn blue at 40%, whereas on the A2 the device LED turns blue at 60%. So, the Caliburn A2 gives you a more realistic indication of your current battery life status.

    Charger not included

    The device kit does NOT include a USB-C charger. We hate this trend, but more and more products are coming out without a charging cable in order to maximize profits. However, if you purchase the Caliburn A2 Starter Bundle, it comes with a USB-C charging cable for free!

    Same 520 mAh battery

    The A2 has the same 520mAh battery as the original Caliburn (unfortunately). Because it uses 30% more power than the original, it will also lose charge faster. So if you puff on the A2 the same amount as the original Caliburn, it's going to feel like you lost battery life.

    If you use the A2 less frequently than the original, since you're getting more nicotine per inhale, then you won't notice a difference. I highly recommend having a second device to make sure that you have a backup to use for the entire day.

    Should I upgrade from my original Caliburn?

    That's entirely up to you! The best part about the Caliburn A2 is that it includes everything we loved about the Caliburn but with significant improvements. It charges up quicker, provides a stronger and more flavorful puff and is way easier for monitoring juice levels. So, if you love the Caliburn but wish you could crank up the volume—then you might want to upgrade to the A2.

    What's the "Caliburn" hype about?

    So we've been using and testing the many nic salt devices that have come out for the past few years and we hadn't found one that we really thought hit the mark for us.

    We wanted a device with the following:

    1. Great flavor

    2. Long-lasting pods

    3. Great battery life

    4. Solid build quality

    5. Affordable

    The Uwell Caliburn and the new Caliburn A2 were able to meet these points for us, which is why we decided to pick them up and sell them to our customers nearly at cost. In fact, if you get the Caliburn A2 Starter Bundle, it's a free upgrade considering the total value of the other items!

    How easy is it to use?

    The Caliburn A2 is as easy as it gets. The device comes fully charged out of the box. No real instructions are needed as the device itself is very straightforward. Simply take the device out, snap off the mouthpiece from a pod and fill it up with our Handcrafted Salt E-Liquid. With a fresh pod, let it sit for at least five minutes before using for the first time to allow the coil time to wick.

    We believe in making vaping as easy and convenient as possible, and the A2 Caliburn fits the bill.

    How long does the battery last?

    Though the raw specs of the device's battery are not very impressive (especially when compared to the specs of a sub-ohm device) you will find that in actuality the battery should last you most of a day if not an entire day. The Caliburn A2 has no taper-off so that means it will continue to hit as perfectly at 20% as it does at 100% charge.

    The device itself charges from dead to full in about 35 minutes. From personal experience, I can tell you that I need to charge my Caliburn A2 on average twice a day if I am chain vaping.

    How long do the pods last?

    On average you should be able to get roughly three weeks to a month on each A2 Caliburn pod when using our handcrafted salts. That's almost two times longer than the original Caliburn pods!

    When using regular commercial nic salts which contain high amounts of sucralose, your mileage may vary. You'll be lucky to get a whole week out of them when using overly sweetened juices.

    What juice can I use with it?

    Both freebase and nic salt juice works with the Caliburn A2. The optimal PG/VG ratio for the Caliburn pods is around 60/40. Most commercial nic salt products are formulated with a 50/50 ratio which can cause heavy leaking or spitback with Caliburn pods.

    You'll also want to choose a nic strength that works with your tolerance level and with the power output of the device itself. We found that high nicotine juices hit even harder in the Caliburn A2.



    We take pride in keeping our customers satisfied. That is the main reason why we have stayed in business for seven years, aside from our awesome flavors. We make the whole experience easy.

    If your pod or device needs to be replaced, we take care of it directly. This is the only site that offers a full-service experience for the Caliburn, or for open-end devices in general. We're not just about pushing units, we go the extra mile to solve any problems you might run into, instead of making you hunt down the manufacturer yourself—like most online shops will have you do.

    How to register

    We highly recommend registering your products on our site. You'll be accommodated either way, but it is the easiest and best way to keep track of your serial numbers. If you ever run into an issue, simply file a claim directly using our Warranty page. Once we receive your claim, we will hook you up with a brand new device or a pod pack for your troubles.

    Light, long-lasting, and good build quality!

    Device is deceptively well made. I got faked out by how light it is! The charge lasts well longer than any amount of time I go out.

    The pods are diesel, too. Got about ten or 12 fills out if it, maybe more. Spring Surprise Mystery Flavor is nice.

    Probably going to order again and make this my out and about piece.

    love the new mystery flavor

    another superb order. best vape liquids company around! no cap all tax.

    Great Service

    Absolutely great service from start to finish. Will not use another company again. The flavors are great! The service is spot on and the shipping is fast and affordable.

    Magnets that hold pod in ecig already fell out

    Juice is great as always. Just the magnets that hold the pod down have already fallen out so pods fall out easily and don't sit correctly in the ecig anymore
