Review Summary


The KandyPens C-Box (Pro & Mini) both have intuitive design and functions great in their respective price range. The C-Box Pro is button-activated that has four temp settings, while the C-Box Mini is draw-activated that has a single voltage setting (3.7V). Choosing between the two is a matter of preference. As for me, I liked using the Pro version since it can fit bigger cartridges and has four variable voltages for different vaping profiles. Regardless of what you choose, both vapes can produce good quality vapor that’s appealing for beginners.


KandyPens is one of the popular brands in the wax and oil vapes industry. They recently released the KP Crystal 2 (Review) that features a ‘coil-less quartz bowl' and is currently the top-selling wax pen around. They also have the KP Oura for hardcore users who want to vape on a fine-quality portable eRig.

KandyPens C-Box Design
The KandyPens C-Box is a sleek, portable device that includes different sized magnetic thread connectors for customized cartridge height adjustment.

On the other hand, the C-Box by KandyPens (Visit Website) has two versions: The Pro and the Mini. Both vaporizers are compatible with 510-threaded CBD/THC cartridges, which are connected via magnetic adapters. The C-Box Pro has four voltage settings and a power button, while the Mini has a single temp setting and has a draw-activated function. We'll explore more of the similarities and differences between both vaporizers below.

Design & Features

The C-box has a nice, sleek design that feels good in the hand.

With the word ‘box' in the name, you have a good idea of what KandyPens C-Box (Pro & Mini) looks like- it's a conceal type vaporizer that's generally box-shaped with a curvy rectangular design that sets it apart from other conceal type batteries.

KandyPens C-Box is made from aluminum, which makes it durable for a small device. It has an ergonomic design, and the Pro version is about 3 inches tall, while the Mini version is half an inch shorter. Regardless of which version, both devices are easy to carry and can be put in any pocket/purse.

The KandyPens C-box side has a window that indicates the level of the oil in the cartridge. On the other end, this is where the design of the Pro and Mini differs. The Mini has a curvy side, while the Pro has a flat section where the power button and LED light are located. This makes the Pro have a unique shape that feels good to hold. The button is well-placed since my thumb naturally rests on it while holding the device.

Magnetic Threaded Adapters

The magnetic adapters make the C-box very easy to use with any 510 threaded cartridge.

The C-Box Pro has an opening on top that's wide enough to fit any carts up to 10.55mm. As you can see, there are two sets of magnetic thread adapters- a shorter pair and a longer pair. These magnetic thread adapters let you choose how far you want the mouthpiece to stick out of the battery.

Take note that if you use larger cartridges, C-Box Mini won't accommodate it since it can only fit carts with a diameter of 9.6mm or below. It would have been nice if the C-Box Mini could fit all 510 pre-filled cartridges like the Yocan Uni (Review).

How to Use

The KandyPens C-Box is simple to use, especially with the Mini version since you can just inhale from the mouthpiece to use it. The C-Box Pro has a single button for turning on/off the device and picking any four voltage settings. To use it, you need to:

  1. Select the Magnetic Adapter you want to use.
  2. Screw the THC/CBD cartridge onto it.
  3. Place the cartridge into the cartridge receptacle of the battery.
  4. Press the power button five times to turn on the battery
  5. Select the voltage settings by pressing the power button three times.
  6. Hold the power button as you inhale from the mouthpiece.

Voltage Settings: 2.3V (Blue) | 3.0V (Green) | 3.6V (Yellow) | 4.2V (Red)

C-Box Pro VS C-Box Mini

KandyPens C Box Pro

As I've mentioned above, the C-Box Mini is about 2.5″ tall, which almost has the same size as a lighter. It has an aluminum alloy body and packs a 390 mAh battery like the C-Box Pro.

There are some minor adjustments in the C-Box Mini:

  • The Mini doesn't have the multiple voltage settings of the C-Box Pro, but instead, it runs on a single voltage, which is 3.7V. Yes, it's slightly higher than the Pro's second-highest voltage setting, which means that the Mini strikes a nice balance between big clouds and flavor.
  • The C-Box Mini only has a set of magnetic adapters compared to the Pro that has two. So you'll need extra care not to lose either of the magnetic adapters.
  • The C-Box Mini is draw-activated, so you can take a hit from it whenever you want without pressing a power button, which is the case in the C-Box Pro.
  • Since the Mini is a smaller device, you can expect the mouthpiece to stick out more than the Pro. Also, the Mini gets a little warmer than the Pro while it's in use. This is always the case when you have a big power packed in a small body, so keep that in mind when using it.

Overall, the C-Box Mini is quite similar to the C-Box Pro. The major difference is that the C-Box Mini can't fit larger cartridges higher than 9.6mm, unlike the Pro, where it can fit any carts up to 10.55mm. Unfortunately, C-Box Pro costs more than the Mini, which retails for $50, while the Mini costs $25 from KandyPens (Visit Store)

Performance & Vapor Quality

KandyPens C-Box heats up quickly regardless of the version. The C-Box Mini is simple and straightforward that can produce decent vapor for beginners. However, the issue with the C-Box Mini is it gets warm after 5-7 good hits.

On using the C-Box Pro, the four voltage settings let me customize my session compared to the Mini with a single temperature. I like vaping on lower temp settings so that I'll get mild and flavorful vapor. And if I want to have more clouds while sacrificing a little bit of flavor, I'll tweak it to the higher voltage settings.

As usual, the vapor quality depends on the cartridge. So if you want to have a good time, I suggest you buy something like Bloom Farms CBD or Jetty CBD, which both have high CBD content, and the flavors are great. If you're new, I would recommend you use the C-Box Pro so that you'll have control over the temp setting, and you'll be able to identify which vaping profile suits you best.

Battery Performance: The C-Box has a 390 mAh battery, which is good for a full day of casual vaping. Recharging takes under an hour, so you will never be without the C-Box for long.

Bottom Line

KandyPens c-box 510 battery

Overall, Both KandyPens C-Box (Pro & Mini) work great on their respective price range. It has a fast heat-up time, a long battery life and designed to be simple for beginners. The C-Box Pro is suitable for vapers who specifically vape bigger carts since the Mini can only fit cartridges with 9.6mm or less.

On the other hand, the C-Box Mini is more portable and discreet that packs almost the same power as the C-Box Pro. With that being said, I recommend the C-Box Pro since I can pick the temp settings to suit my vaping profile, and it doesn't get warm, unlike the C-Box Mini. If you're looking for a better option to vape THC/CBD cartridges, I suggest you look into KandyPens Special K (Review), which is currently the best 510 battery this 2024.
