ISH - Best Small Vape Pen For 510 Thread Carts

Vape pens are an increasingly popular way to consume cannabis extracted THC oil. They are discreet, easy to use, and rechargeable. These are the qualities that can be found with the ISH vape pen battery, which is a small battery for 510-thread oil cartridges. It was our goal to make the most affordable and compact vape pen on the market. We successfully developed an inexpensive 510-thread vape battery that hits better than options that cost a lot more. Get more bang for your buck with the smallest vape pen that has a price just as small, while still providing a premium vaping experience. 

Vape pens, while incredibly convenient, make them an easy item to lose track of. That’s why when we designed the ISH battery we kept both portability and cost top of mind so that if you do lose your battery you’re only out $9.99.  The ISH vape pen battery is a universally compatible 510-thread battery with a simple single 3.2 voltage, making it a great choice for just about any 510-thread prefilled cannabis oil cartridge (although we’re partial to O.pen cartridges ;)

One Voltage Setting Optimal For Most 510-Thread Carts

Don’t worry about trying to figure out the best voltage setting for your THC carts, the ISH is optimized with just one voltage setting (3.2V) that works well with almost any pre-filled cannabis oil cartridge. The O.pen ISH is a 510-thread vape pen battery, 510-threaded batteries are the universal design for batteries and are compatible with the majority of vape pen cartridges. If you’re buying a prefilled cartridge, chances are that cartridge will be 510-thread compatible. However, 510-thread batteries are also compatible with many refillable oil tanks and wax atomizers. 

It’s important to not overheat your vape pen battery, as higher temperatures can both damage the cannabis oil and damage the pen itself. The O.pen ISH Battery comes at a standard one temperature setting to mitigate the possibility of overheating. The temperature also provides smooth and consistent hits. 

Draw Activation 

First-time users can often be intimidated by vapes, as they seem less intuitive than a traditional joint. People often wonder what buttons they have to press and how long they have to hold before they can inhale. 

However, the O.pen ISH Battery is draw-activated, meaning there are no buttons to press. You simply inhale and the battery heats itself. This eliminates any need to turn your vape pen on or and bypasses the process of having to wait for the battery to heat up. 

Discreet Use 

The O.pen ISH battery allows for full discretion with a battery length of only 3 inches, making it one of the most compact batteries available on the market. It can easily be hidden in one's hand for a discreet vape hit. A large part of the appeal for small vape pens is discretion. Vaping THC oil smells less compared to smoking cannabis flower, and is a big factor behind the surge in the popularity of THC carts.

How to Use 

The O.pen ISH battery comes partially charged, but it’s recommended that users charge their battery fully before usage. The battery comes as a USB that can be plugged into any conventional outlet or even a laptop. Once the battery is fully charged, simply screw it onto the vape cartridge and inhale. The small size makes it easy to store and carry around. Remember, to disconnect your cartridge and battery when not in use for child safety.


The O.pen ISH battery has a controlled temperature, thereby negating the risk of the battery overheating and exploding.

If you have our 2.0 Variable Voltage Battery there are a few extra bells and whistles. If it doesn’t work upon inhale, simply click the stylus tip 5x to turn on the battery and it will illuminate. You can also change heat settings by clicking 2x. 

Our Original and ISH vaporizer pens are a simple as can be! Once charged, just attach your favorite cartridge and inhale for up to 8 seconds to get your perfect puff.

If your pen needs charging, just plug it in to your USB charger that comes with your vaporizer. Once the indicator light on the O.pen charger turns green, the tip of the pen will stop pulsing to let you know the pen is fully charged.

  1. Just pay one-way shipping to return the vaporizer pen to us and we will replace your O.pen with a brand new pen, including a new charger.
  2. Or you can choose our expedited warranty, which costs $10 for a brand new pen ordered from our site and does include a charger and shipping. Once you have contacted us and your device has been deemed defective, we will issue you a coupon for your new pen to be bought online.

Our pens and cartridges go together like peanut butter and jelly, like milk and cookies, like a burger and fries. Why mess with perfection? While another cartridge should work with your O.pen, we cannot guarantee that non-O.pen cartridges will work with your pen.

To make sure your cartridge works the best it can we recommend not exposing your vape pen cartridges to extreme heat or cold which could cause the oil to leak. We also recommend storing your cartridge separately from your O.pen battery and charger for child safety.


We are proud to say that none of our products contain or have contained Vitamin E or Vitamin E acetate since our inception in 2012.
