The KandyPens C-Box features two vaporizer versions. One is the C-Box Pro, which has a 390mAh battery capacity and four variable voltage settings. The other is the C-Box Mini, which also has an internal 390mAh capacity but uses an automatic draw-style and has no batteries or variable voltage settings.

The Pro has a greater vaping capacity and stands at just over 3” tall. The Mini has a slighter build, an all-aluminum alloy exterior, and has a buttonless exterior. Both versions come with two magnetic adapters so vapers use a wide variety of e-juice/oil cartridges with either mod.

A Closer Look at the C-Box Pro

The C-Box Pro has an intuitive, easy-to-navigate design. It has only a single button on its aluminum alloy-frame and the e-juice/oil cartridge slot up top can conceal any type of cartridge depending on its size or shape. The C-Box Pro has a circular side, probably where the battery is housed, while the rest of the exterior has grooves on either side to make the mod ergonomic.

The Pro has an opening up top that measures around 9mm in diameter but can accommodate tanks as large as 10.5mm (0.4”). The power button sits near the top of the device and there is a small pin-hole LED above it. The LED shows users the current power setting as well as the current battery level.

The Pro stands at just over 3” tall so it has a low-profile. It is lightweight and can easily disappear in a closed fist. There are two magnetic adapters included in the kit (the Mini version also has two adapters). Users can attach them to any non-510 threaded tank and use them with the Pro or the Mini.

What’s in the C-Box Kit

There’s not a lot in the KandyPens C-Box Pro kit. It is a simple device and only comes with what it needs to get started, namely the device itself, and the two magnetic adapters. Users have to use a USB charging cable of their own, as the kit does not include one, even though the battery uses USB charging.

Here’s what to expect in the C-Box kit;

  • One x KandyPens C-Box Pro
  • Two x Magnetic Adapters

How the Device Performs

The C-Box Pro has very easy functioning. Users need to first see what magnetic adapter is compatible with their tank, or if it has 510-threading then they can use their tank without the adapter. The C-Box Pro is supposed to support tanks that can resist higher voltages so if you have one of those tanks, the C-Box Pro is the ideal mod.

The button has a good throw to it and depresses easily. It does not get stuck and responds very fast when it is pressed. Users can choose from four different voltage levels represented by four different colored LED lights:

  • Blue – 2.3V
  • Green – 3.0V
  • Yellow – 3.6V
  • Red – 4.2V

The mod takes five clicks of the power button to activate. Users need to press the button three times to cycle through the four power settings. When they have chosen a setting, they can let the device heat-up for a few seconds, and then press the button again to inhale. The battery capacity is enough to last a day, and the charging time for the 390mAh is just under one hour.

A Closer Look at the C-Box Mini

As its title suggests, the C-Box Mini is a smaller version of the C-Box Pro. The Mini version has a smaller build standing at just under 2.7” but it still features an internal battery with a capacity of 390mAh. So users have about the same amount of battery life for both devices. What the Mini does not have are variable voltage settings.

The Mini is also a draw-activated portable vaporizer so its exterior is button-free. Users can screw in one of the adapters in the kit (something it also has in common with the Pro version) and insert the cartridge into the slot. Once it is in place, they can start inhaling from the mouthpiece.

The Mini also has a slender, aluminum-alloy build, which makes it slightly more lightweight than its companion device. The Mini does use a USB charging port on its side so users can recharge the battery, which takes about the same amount of time as the Pro, under one hour. But, the device does not enable pass-through charging.

What’s in the C-Box Mini Box

The Mini version of the mod comes with the same sparsely accessorized box as the original. Do not expect to get much other than the mod and the magnetic adapters. Some vendors are selling it with a USB charging cable but it is not across the board.

KandyPens C-Box Mini kit

Here’s what to expect from the Mini kit:

  • One x KandyPens C-Box Mini
  • Two x Magnetic Adapters
  • One x Micro USB charging cable

How the Device Performs

The Mini has about as much performance quality as the original. The Mini comes in a smaller package, but its performance tries to match the performance of its larger counterpart. The Mini has much easier usability, as it is draw-activated and there is no power regulation. The vaporizer operates on a direct voltage output of around 3.7V, which is the middle power option of the Pro.

The length of a user’s draw is also a way to switch up vapor quality. Users can take a quick two or three-second hit and get minimal vapor. They can also take longer draws, which translates to more vapor, so the vape device is very responsive. The vaporizer can get a little warm when taking long inhales, but it is not so bad.

The two vaporizers have the same battery capacity so their battery life is nearly the same. Users can switch the power output with the Pro, but they can also regulate their draws with the Mini so it comes out to nearly the same amount of control. The Mini can also be recharged in under an hour.

Competing Devices

C-Box Battle

The two versions of the C-Box appeal to different types of vapers. Those who enjoy variable voltage settings and more control will like the Pro. While those who are maybe starting vaping will enjoy the easy usability of the Mini. The Mini is smaller than the Pro but not by a lot, only three-quarters of an inch so the difference in size is negligible.

They both have the same battery capacity so there is also not much of a difference. The Pro is a bit pricey when compared to other 510-mods including the Mini, so that could be a deciding factor.


The Silo is another popular 510-mod for tanks and cartridges. It is also a concealer device in that the tank disappears into the mod’s slot, while the mouthpiece sticks out of the top. The CCELL Silo is very concealable and measures only 2.5” so it is even smaller than the Mini.


It also has a larger capacity battery than either the C-Box model, 500mAh, but it does not feature variable voltage settings. The Silo is draw-activated so it has no buttons on it, which also means that it does not have multiple power settings.

Positives and Negatives

The Positives

  • Easy-to-use
  • Concealable and convenient
  • Good battery life
  • Fast charging time
  • Good vapor quality
  • Lifetime warranty

The Negatives

  • Could have a better battery life
  • Larger battery capacity

Conclusion: KandyPens C-Box Review: Vaping Outside the Box

The KandyPens C-Box Pro and Mini are convenient, easy-to-use devices. They both feature good battery life, even though maybe one should have had more than the other. The Silo is smaller than both devices but still has a larger battery capacity. The Pro gives users more flexibility in terms of power settings, but the Mini gives users ease-of-use with its draw-activated mechanism.

They are both portable and concealable and maintain a low-profile when out and about. The vapor quality is good for both devices, although users who want bigger, thicker clouds should opt for the variable voltage Pro, which has more power. The devices both charge very fast and have good build quality.

I was a smoker for over 25 years. In this time I also earned my medical degree with a specialization in addiction treatment and counseling. That period has led me to vaping, my interest started around 2011. I’m fighting the tide of hysteria and dis-information around vaping that emanates from various fronts legislative, cultural and scientific. Having scientific councils support, I’m happy to contribute my thoughts, articles, and expertise.
