Boundless Terp Pen XL

The Terp Pen XL is an upgraded version of the Boundless Terp Pen, both of which were created by the brand Boundless Technology. This portable vaporizer features a minimalistic design with a stainless steel body that offers an appealing look and a durable style. Rather than loading your concentrate in a chamber, there’s a quartz bucket in which you can put your concentrate and hover the ceramic coil over to take a hit. But there are a few other ways to vape as well. Furthermore, with a 700mAh battery, this device offers three adjustable voltage modes, instant heat-up time, and recharges in 45 minutes.

Voltage settings

With this pen, you can choose the intensity of your vapor or taste preference by selecting one of the three heat settings. You tap on the top of the battery to toggle through the options; as you do, the LED light will display a blue, green, or red color. Each color indicates the voltage setting of choice.

  • Blue: 3.3V
  • Green: 3.7V
  • Red: 4.0V

As with any device you vape with, the lowest heat setting produces the most flavor and discretion. At the same time, the highest setting produces the thickest cloud and strongest effects.


Cleaning your vape pen is a necessary part of its maintenance and longevity. Fortunately, the cleaning time of the Terp Pen XL is short, and it’s simple to do. Cleaning the coil requires you to untwist the storage container and draw from the mouthpiece. This burns off any residue and helps the coil function more optimally. Once the pen cools down completely, remove the device and wipe each piece down with Isopropyl alcohol. Once all parts are dry, reassemble, and you’re all set for your next vape session.

Modern features

The Terp Pen XL has a few great features that make using the device a breeze. First, it utilizes touch sensor technology, which allows you to select your preferred heat setting with a few taps. Also, after choosing your voltage mode, the pen produces vapor through breath activation. This occurs instantly as you begin to inhale from the mouthpiece. Finally, the device gives you flexibility in how you vape. You can load your concentrate in the quartz storage bucket, vape straight from your dab tool, or bring the ceramic coil to your jar of concentrate.
