Looking to buy a vape pen for THC carts? In this article, we’ll cover the most important factors to consider when buying a new vape pen for THC carts to allow for the most optimal vaping experience possible.
What is a Vape Pen?
Looking for a way to enjoy the benefits of cannabis discreetly? Cannabis oil cartridges may be the answer which have seen a massive rise in popularity as cannabis legalization continues to gain momentum. THC carts allow for ease-of-use and discretion unlike traditional smoking methods which involve buying weed, grinding it up, and lighting it with lighter. THC oil carts come prefilled from the dispensary and only require a charged vape pen battery and cartridge to get started.
Vape pens or vape pen batteries are a necessary component in vaping cannabis. Typically they are rechargeable lithium ion batteries that have a preset voltage setting, or multiple voltage settings to heat up the THC oil and enable vapor production. The most common type of vape pen battery connection is the 510 thread, which is a universal connection point for vape pens. Vape pens are the second most popular way to consume cannabis largely due to their convenience and ability to offer a similar experience to smoking cannabis flower. For around $50-75 a consumer can purchase a THC cartridge and vape pen battery which are all of the components required to get started with vaping.
510 Thread Vape Battery Connection Is The Most Common Type
A 510-thread connection is the threading used to connect a THC cartridge to a vape pen battery and is often referred to as a universal connection point as it is used by most cartridge manufacturers. This allows consumers to experiment between cartridges and batteries without having to purchase custom set-ups each time. A user simply needs to purchase a prefilled THC cartridge from the dispensary and then screw it onto the vape pen battery of their choice.
Different THC oils have different consistencies, including oil thickness and terpene levels that will perform better at different heat settings so it’s important to understand what heat or voltage settings are available with your cartridge. If you’re looking for a solid vape pen with a plethora of features, O.pen vape pens has you covered. We have spent the last few years perfecting the vape pen to bring you an unparalleled vaping experience. Below we explore different things you might consider when purchasing a vape pen battery.
Features to Consider When Purchasing a Vape Pen

Vape Pen Voltage Settings
THC cartridges are not created equally, there are a variety of cannabis oil extracts you can purchase as prefilled THC cartridges including, distillate, live resin, and rosin, all of these extract have different oil compositions and varying levels of cannabinoids and terpenes. The variance from cartridge to cartridge requires different temperature or voltage settings to get the best out of your puff. Thicker oils will require higher heat settings and terpene rich cartridges will offer a better flavor profile at lower heat settings. You can learn more about the best voltage setting for THC carts in our blog. The O.pen 2.0 Variable Voltage vape pen battery is equipped with 4 distinct voltage settings to deliver an optimal vaping experience no matter what 510-thread cartridge you choose to use.
Vape Pen Battery Life
Vape pen battery life is measured in mAH (or milliamp hours) which often range from 150-900 mAh depending on the type of vaping you are doing. O.pen vape pen batteries offer 180 mAh of power, allowing for a more discreet form factor but will require a bit more charging, around 3 times to finish a 1 gram cartridge in its entirety, however it should be plenty of battery life to last a full day of regular usage.
Vape Pen Size

We even offer our ultra-discreet ISH vape pen measuring at just 3 inches tall. Many other vape pen batteries available will have a bulkier form factor.

2.0 Variable Voltage Vape Pen Battery
Our best selling vape pen, the O.pen 2.0 Variable Voltage Battery takes the sleek pen style, draw-activated design of the O.riginal vape pen and adds a few additional bells and whistles. This pen comes with temperature control features, allowing users to cycle between four voltage modes depending on the cartridge being used and user preference.
The pen’s four heat modes are:
- Low – 2.4v. If you have something that is terpene-based, like live-resin this temperature setting is perfect for you.
- Medium – 3.2v. The standard setting for smoking oil cartridges. This will generally get your oil heated to a perfect level for smooth and potent hits.
- High – 4.0v. If you want to turn it up a notch, you can kick it into high gear with this setting. Be careful though, because this setting can burn certain oils.
- Dab – The highest setting available. If you’re smoking wax or shatter, this is the setting that will really vaporize your concentrate. Proceed with caution though, as this can absolutely scorch your oil. Only use this setting for oils and concentrates that you know can handle the heat.
Users can now discreetly take draw-activated hits with a vape pen that is versatile and customizable. Equipped with a rapid charge feature that can charge your pen in 20 minutes, the O.pen 2.0 Variable Voltage Battery redefines convenience for the vape pen category.
