O.pen

What O.pen Actually Makes

O.pen got its start in 2012, founded by six cannabis growers and dispensary operators who saw the same gap: great oils were everywhere, but the hardware to vaporize them was inconsistent and frustrating. They built their first vaporizers with a simple goal in mind. Make something reliable, easy to use, and built to last. Over a decade later, that mission still shows up in every product they release.

Their catalog focuses on 510-thread batteries and vaporizer pens. That means they are designed to work with the pre-filled oil cartridges you already know and love. No proprietary pods. No guessing about compatibility. If it has a 510 thread, an O.pen battery will fire it.

O.pen 2.0 and the Battery Lineup

The O.pen 2.0 became a defining product for the brand because it proved that a slim, buttonless draw-activated battery could still deliver a consistent hit. Inhale to activate, pocket it between sessions. That simplicity is intentional, not a corner cut.

Beyond the 2.0, O.pen offers batteries in different output settings, so you can dial in the heat based on the viscosity of your oil. Thicker distillate cartridges tend to do better at slightly higher voltages. Thinner live resin oils often shine at lower temps where terpenes stay intact. Having options matters, and O.pen builds that flexibility into their hardware.

If you are newer to vape batteries and want a deeper breakdown of how 510-thread devices work, our vapes blog covers the basics and then some.

Why 510-Thread Is Still the Standard

The cannabis industry has cycled through a lot of hardware formats. Proprietary pods, magnetic connections, brand-locked ecosystems. And yet 510-thread remains the most widely compatible standard by a wide margin. Dispensaries fill 510 carts. Third-party brands make 510 carts. Your battery and your cartridge will almost always share that thread if both are built for it.

O.pen bet on that standard early and stayed consistent. That is part of why they ended up in thousands of retail locations across the country and why their batteries still sell as well today as they did years ago.

How to Choose the Right O.pen Battery

A few things worth thinking through before you pick one:

• Draw activation vs. button activation. Draw-activated batteries like the 2.0 are simpler and more discreet. Button-activated batteries give you more control over when the coil fires, which some people prefer for thicker oils.
• Voltage settings. Variable voltage batteries let you tune heat to your cartridge. One setting is not right for every oil type. If you use a variety of carts, adjustable output is worth it.
• Battery capacity. A bigger battery means fewer charges per week. If you are a daily user, look for something with more mAh. If you are occasional, a slim low-profile option works great.
• Size and carry habit. O.pen makes both pocket-friendly slim batteries and slightly larger options with more features. Match it to how and where you actually use it.

Frequently Asked Questions

What does 510-thread mean on an O.pen battery?

510-thread refers to the connector standard used by most vape cartridges and batteries in the cannabis space. It describes the thread pattern on the connection point: 10 threads at 0.5mm each. O.pen batteries use this standard, so they are compatible with the vast majority of pre-filled oil cartridges sold at dispensaries and online.

Is the O.pen 2.0 a good battery for beginners?

It is one of the most beginner-friendly options on the market. There is no button to figure out. You just inhale and it activates. The draw resistance is tuned for a smooth hit, and the slim profile makes it easy to carry and conceal. It strips the process down to what matters: attach your cartridge and go.

Can I use O.pen batteries with any cartridge?

Any cartridge with a standard 510-thread connection will work with O.pen batteries. That covers the overwhelming majority of pre-filled THC, CBD, and THC-adjacent oil cartridges. The only exception would be proprietary pod systems that use a different connection format, but those are not 510-thread by definition.
