Design and Features


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.

With the word box in the name, you have a good idea of what the KandyPens C-Box looks like. It’s a conceal type vaporizer and yes, it is generally box-shaped, but it has a curvy, rectangular design that sets it apart from other conceal batteries. The C-Box has an opening that is wide enough to accommodate cartridges that have a width of 9.6 mm or less.

If you use larger cartridges, then you need to get the C-Box Pro, which can fit carts up to 10.55 mm in diameter. Unfortunately, it costs more than the basic C-Box. It would have been nice if the C-Box could fit all sized cartridges like the Yocan Uni, but at least you have a choice.

The C-Box is very comfortable to hold because of its interesting shape, the section where the button is located is flat, but the section where you insert the cartridge is rounded. That gives the device a unique shape that feels good to hold. The C-Box is only three inches tall so it is as easily portable as any other 510 battery despite the unique shape.


The C-Box is designed to work with higher voltage cartridges, so if you have any lying around, this is the battery with which to use them. The C-Box also includes two sets of magnetic thread connectors, a shorter pair and a longer pair. That way you can choose how far you want the cartridge to stick out of the battery. It also trumps many other 510 batteries by having four voltage settings instead of three, they are 2.3V, 3.0V, 3.6V, and 4.2V.

How to Use

  1. Select the magnetic adapter you want to use and then screw the oil/CBD cartridge onto it.
  2. Place the adapter and cartridge into the cartridge receptacle of the battery.
  3. Press the power button five times to turn on the battery.
  4. Select your preferred voltage setting by pressing the power button three times.
  5. Once heating is complete, inhale from the mouthpiece of the cartridge while holding down the power button.

Performance and Vapor Quality

KandyPens C-Box Performance
The KandyPens C-Box’s four voltage settings means that it works well with a wide variety of cartridges.


The C-Box heats up pretty quickly and the body stays cool regardless of the voltage setting. A lot of the top 510 batteries are button activated but the C-Box is draw activated. That isn’t a big deal because the button is well placed at the top of the device where your thumb naturally rests when you’re holding it.

Vapor Quality

As usual, the quality of the vapor depends on the quality of the cartridge. So get a great cartridge like a Gold Line cartridge for example, and you’ll have a good time. The four voltage settings give the C-Box some extra customization options, as do the two sets of magnetic connectors. Those voltage settings do make a difference in terms of flavor quality and vapor production, so if you like to tinker around with your settings, you get that option with the C-Box. I would recommend that you start with the lowest setting and work your way up if this is your first time using a 510 battery.

Battery Performance

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