The Best THC Vape Pens of 2021: An Introduction

THC oil vape pens are generally small in size, simple to operate and very portable. THC liquid extract can fit anywhere, so cannabis oil vaporizers do not have to be as large as dry herb devices. The batteries for these units can have variable voltage settings or preset levels that vapers can choose with the click of a button.

LEDs are also common features. They either signal the device is operational or they show cell life. For the units with different power settings, LED lights also show at what level the unit is working. Charging the batteries for these devices is through a USB cable, as they all have USB charging ports, or use their own proprietary port or cable.

All About THC Oil Vape Pens: Everything You Need to Know

THC oil pens consist mostly of three parts:

  • A small capacity battery, usually, but not always with 510-threading
  • A refillable or pre-filled universal 510 cartridge
  • A tank or heating chamber atomizer

There are variations on these three elements. The Mig Vapor HERB-E 7, for example, uses a tank atomizer for vaping concentrates, which is not compatible with any other device. While something like the Amber Rose from KandyPens has 510-threading on both its battery and tank, so they are more versatile.

The Rubi does not have 510-threading, but its pods are refillable and can vape oils, as well as e-juice. A unit like the Aurora vaporizer has a unique magnetic connection, but the full kit comes with three different atomizers made of different materials, like quartz and ceramic.

Unlike dry herb vaporizers, THC pens are simpler, and have less battery capacity, even though something like the Bug has an 1100mAh cell. Weed vapes have ovens, which is different from THC pens.

Oil pens use either:

  • Coil/rod atomizers
  • Flat, disc-shaped heating elements

With a dry herb vaporizer, users load the oven with material to vape and the devices employ either conduction (direct heat contact) or convection (hot air contact) heating styles. Weed vaporizers offer more control also, as most oil pens only have preset, non-adjustable temperature settings.

The FAQ About THC Vape Pens

What is the best wattage to vape THC oil?

Anywhere between 6W and 15W is enough to vape thin or thick cannabis oils. Pre-filled cartomizers, depending on the resistance of the coil, can produce vapor within that range. Any lower and no vapor will emerge; going above 15W may burn the coil, and contaminate the oil. THC has a boiling point of 315F, which is what most THC pen batteries can output.

What is the best voltage to vape THC oil?

THC vape pen batteries usually have a maximum voltage output of 4.2V. The pens with variable voltage settings have ranges starting at 3.3V going to as high as 4.2V or 4.3V, in some cases.

How to vape THC oil?

Screw a pre-filled cartridge onto a 510-threaded cell, turn it on and start vaping. If using a refillable tank/pod/atomizer, fill the chamber with cannabis oil, connect it to the battery, turn it on and start inhaling. Some cells have no buttons, and users need only take a draw to activate the heater. If a pen has variable voltage settings, use each of them to find the ideal power output.

How long does THC stay in the body?

There is no one answer to how long tetrahydrocannabinol stays in the body. Depending on a person’s consumption habits, body weight, age, and gender, the range can be anywhere between 40-80 days for some, and even more, close to 80-90 days for larger, heavier people.

The Last Word

THC oil vape pens have changed how people consume cannabis. The devices here in 2021 are a mix of high-tech, and advanced, as well as reliable, high-quality and still budget units. The options vapers have here are suitable for all levels of experience, from beginners to experts.

These pens are easy-to-use, and even support e-liquid vaping, at least the refillable devices like the Rubi. No button operation is what a lot of vapers prefer, but even the products with one button controls are straightforward.

Even though a lot of these devices have refillable pods or tanks, they require minimal cleaning or maintenance. If someone is looking to enter the world of cannabis vaping, any one of these devices will make a suitable introduction.

    I specifically like CBD Isolate Crystals because they do not contain any THC so I have peace of mind in the case that I have to take a drug test for work because I work for Border Patrol.

      Hi Edibles, thanks for writing in. Glad to hear you’re enjoying CBD isolates. Isolates are a good way to avoid even trace amounts of THC in your body, but if you take them over a long time those trace amounts can build up. If you need to pass a drug test every so often, I would recommend not using CBD for a few weeks before your test so you clear your system of everything. Some chemicals in tests can even turn CBD into THC when they interact with them. Best to err on the side of caution. Hope this helps, let us know how it goes with you.
