Kandypens K-Vape Pro Review: Dry Herb Vaping on the Go

What is it?

The Kandypens K-Vape Pro is a new portable vaporizer for dry herb.  It’s simple to use, plus its small and lightweight size makes it an easy carry. A few of its key features are a cylindrical 0.5-gram ceramic heating chamber, four temperature presets maxing out at 428F, an 1100 mAh battery with pass-thru charging, and a comfortable glass mouthpiece with “cooling technology.” It’s not a mere tip just to put your lips on. This mouthpiece is integral to the experience of the vapor path. It incorporates a clever design that helps disperse the hot vapor into a more comfortable and flavorful hit, even at higher temps. And in typical Kandypens fashion, the devices come with two of those mouthpieces.

What’s in the box?

The K-Vape Pro comes in a nice corrugated white box branded with the Kandypens “K”. Everything you need to begin vaping dry herb is inside except the herb, and isopropyl alcohol (more on that later). Here’s what’s included:

  • K-Vape Pro battery device (rated at 1100 mAh)
  • 2 x K-Vape Pro glass mouthpiece units
  • 2 x shower head screens (attached to mouthpieces)
  • Cylindrical cleaning brush
  • Micro USB charger

Although two mouthpieces come with the kit, I don’t currently see them sold separately on the KP site. Normally you can buy the mouthpieces for their devices separately in case you need a third, fourth, etc. Also, unlike many other KP devices, this kit only comes in all black. I’m surprised it doesn’t come in other colors, but I would choose black even if I had other options!

Product features

The K-Vape Pro is a basically a two-part unit: the vape pen battery, and the glass mouthpiece. Including the mouthpiece, the K-Vape Pro stands only 4.75 inches tall, and just over an inch in diameter at its widest point. It only weighs 2.75 oz. And like all Kandypens’ products, the battery device is backed by a lifetime warranty against defects or sudden death.

The vape pen (battery device)

The vape pen itself is operated by one button with adjustable temperature in four presets with corresponding LED colors. The button is almost flush-set, but it’s raised just enough to be able to feel it without looking. It’s responsive and clicky.

The four preset temperatures and color coding:

  • Yellow: 350F
  • Green: 375F
  • Red: 400F
  • Blue: 428F

The battery device has an automatic cut-off at the five-minute mark to save battery juice and to keep your material from being over-cooked while not in use. The max time I’ve recorded for heat-up time is 34 seconds, and that was at 428F (blue).

Ceramic chamber

The ceramic vaporization chamber is the same type of chamber used in other similar vaporizers. Its long cylindrical shape allows for more consistent and even heating of the herbs. The Kandypens site says it holds 0.5 grams, but I prefer keeping my packs to no more than 0.3 to allow for better airflow. You can get 0.5 grams in, but in my experience, that’s close to overpacking it.


This is what makes the device shine over similar devices with a mouthpiece directly over a ceramic chamber. First of all, the mouthpiece is very comfortable to use. It’s a thick glass and it has flattened sides that transfer little to no real heat. It also feels durable. I’ve dropped mine a couple of times with no signs of cracks or chips. Part of the durability of the glass is also aided by the anodized aluminum base that holds the secret to the K-Vape Pro vapor path.

On the underside of the mouthpiece base is a showerhead-like screen that helps to disperse the heat of the vapor. But the vapor doesn’t simply go straight up to the mouth after that. Inside, sitting above the screen is a “honeycomb” piece that sends the vapor on a zigzag path to further cool it.

How to use

To use the Kandypens K-Vape Pro, it’s as simple as can be. First, take off the mouthpiece. To remove it just pull up and twist a bit on the glass portion; to put it back on, just line it up and push down until you feel it catch. It’s held on firmly by a little tab.

Next, get out your grinder. Grind your material into a fine consistency, and then load it into the chamber. You don’t need to pack it super tightly. I prefer to add around 0.3 grams and tamp it down a tad. Then put the mouthpiece on.

Turn on the device with a quick five-click press of the button. To select your desired temperature, hold the button down for long presses and watch it scroll through the different settings. If you miss the one you wanted to stop at, it will round-robin.

The device needs a short time to get to temp. At the highest temp it takes right around 30 seconds, and less for the lower temps. While the device is reaching temperature, there will be a row of LEDs flashing on the front side of the battery. Once they stop flashing, you’re all set to go.

How does it perform?

For a little dry herb device, the K-Vape Pro surely does the trick! I don’t know your material or your tolerance, but I had no problem getting the desired effects I was after. I can typically get about three good sessions out of a single 0.3-gram pack. I like to start out at green (375F), then onto red (400F), and then I finish it off with a session of blue (428F). By the time I get to blue, I’m feeling good!

I get no hot spots on the herb, and I don’t even need to stir it. And the airflow is nice and smooth; not tight, but not too lose either. Kandypens says it’s a mix of convection and conduction heating. I can’t say for sure, but I can say my device heats evenly. The device itself gets a little warm, but not hot like some of its competitors.

The vapor production is really a non-issue for me with pocketable dry herb vaping. I’m going for effects! But for those that do care, the K-Vape Pro produces fairly decent vapor. It’s not huge clouds as if you’re using a desktop or a big portable, but it’s comparable to other devices like it.

The flavor on the K-Vape Pro is also about average for a ceramic chamber device, although the clever design of the vapor path and mouthpiece elevates the experience. As with all devices used with dry herbs, the mouthpiece can positively or negatively affect the perception of flavor. With the K-Vape Pro, it’s all positive. If you have good-tasting herb, the K-Vape Pro will allow you to taste it. If your herb is schwag, no device will make it taste otherwise.

Battery and LEDs

As difficult as it was for me to keep tabs on how many sessions I got out of one charge, I did it! At 428F (blue), I got 11 five-minute sessions. That’s just about a full hour of total vaping time. I use another portable of a comparable size that gets about four sessions before needing a charge. Although the other one has a replaceable 18350, I prefer the comfort and security of a battery like in the K-Vape Pro that I know is going to last a long time. 1100 mAh is a nice-sized battery for this device.

But, the battery takes a long time to charge. I tried to clock it but I kept missing the end. It’s at least a couple hours, but maybe even closer to three hours. The device is fully charged when all LEDs are lit. The last LED seemed like it took forever to turn solid! Luckily it has pass-thru charging so you won’t actually have to wait to use it if it’s charging.

How to clean

WIth a ceramic chamber, it’s best to keep it brushed out after a session… but it will remain easy to clean with basic maintenance. The mouthpiece is trickier to clean. Of course, a brush, a cotton swab, and some iso will work wonders for you. But make sure to pay close attention to how the internals of the mouthpiece are put back together.

The mouthpiece has a section that houses the screen that gets unscrewed (there’s only two that comes with the kit). When you unscrew it, make sure the screen doesn’t fall out and go to your nearest floor vent! And there’s also the white plastic piece inside that you have to keep tabs on. With all those pieces, you can clean them with iso and be back to like-new condition.

The cool part of KP including a second mouthpiece on their kits is that when one is dirty, you can reach for the clean one and get to business.

Note: Before I use a portable vaporizer like this, I like to take everything apart, clean it down with isopropyl, and then repeat that a few times. Then I do a “burn-off” where you allow the device to cycle through a few sessions with an empty chamber.

Pros / Cons

  • Simple to use
  • Long-lasting battery
  • Lightweight
  • Four preset temps
  • Even heating
  • Strong effects
  • Decent flavor and vapor
  • Nicely designed mouthpiece
  • Lifetime warranty on the battery
  • Long charge


The K-Vape Pro is a solid portable vaporizer for its size. What I like most about it is the even heating, the long-lasting battery, and the nicely designed mouthpiece. And especially that there’s two of them included in the kit. I wish I could get that same mouthpiece on other devices!

The Kandypens’ lifetime warranty on the battery is also hard to beat. If I had a dollar for every time someone said to me, “my vape pen stopped working.” There’s normally no other option but to buy another. When you factor in all those repeat purchases, it puts those so-called cheap prices in perspective.

The K-Vape Pro costs $99. Sure, you can find less expensive devices but I doubt you’ll find many with warranties.

I regret buying the K Vape Pro. Unit took 8 hours for the battery to charge 75% – three lights out of four. Never fully charged – fourth light kept blinking after 24 hours. Not able to get any vapor. Customer service has been horrible., Had to take a video and they still insisted I was doing something wrong. All I want to do Is send back the unit to get repaired or a new one.

Did you ever get resolution or did the unit finally full charge?

That is why I pay for EVERYTHING with a B Of A debit card.I can go online and dispute an issue and the money is put back IMMEDIATELY and I have NEVER had B Of A change their mind and take the money back.I have done this 4 times in the last 15 years.
