The Flip Ultra by O2 vape has a unique design coupled with premium features that offer a beautiful package.

O2 Vape is a veteran owned company that’s been around since 2013, and been building their reputation ever since. O2 has always released unique and exclusive products, and their latest offering is no different. The Flip Ultra Vape is a stunning product packed with state-of-the-art features.

The Flip Ultra comes packed with all the latest fixtures and has a high-quality design built with the best materials. It sports a premium matte black rubber finish and is perfectly portable for use on the go. As the name suggests, it utilizes patented flip technology, which gives it a serious edge over other products in the same range.

The Flip Ultra is one of their most portable and powerful devices ever, which offers a unique blend of stunning form-factor and exceptional performance. However, is their patented flip design made to look like a key-fob an industry innovation, or is it just a gimmick?

Inside The Flip Ultra

The O2 Vape Flip Ultra utilizes a 650mAh battery, which offers an output that ranges between 2.7V to 4.8V. Along with its high power, it also provides an impressive battery life. The Flip Ultra battery can be charged via a micro USB or an iPhone lightning charging port. You can release the cartridge by pressing a button, which lets it flip out for use and turns on the digital display simultaneously.

The screen offers a very user-friendly display that provides all vital information, such as its temperature and battery life. The screen also displays a puff counter at the bottom. There are three buttons in total on the Flip Ultra. The smaller button located on the front of the Flip Ultra can be used to adjust the voltage of your vape pen, while the larger button is used to activate your vape. The last button is a mechanical button that draws out the cartridge. As mentioned, the screen is activated automatically when the cartridge flips out.

The Flip Ultra also includes a locking mechanism that is there as a safety net to prevent accidentally flipping out your vape pen while it’s in your pocket. This offers a nice feature that allows you to avoid randomly turning on the vape, leading to battery loss or worse. You don’t have to worry about the battery much, though, as the battery on the Flip Ultra is twice as big as the batteries on many other cart vaporizers.

When you purchase the Flip Ultra, it will come with the vape itself, an empty 0.5 ml cartridge, USB charging cable, and user manual. You can use the empty cartridge to fill it with your oils, meaning you are ready to go as soon as you acquire the Flip Ultra. You can also rest at ease, knowing that the O2 Flip Ultra comes with a lifetime warranty.

Using The Flip Ultra

The Flip Ultra has, without a doubt, offered me one of the best THC vaping experiences of my life. Its solid functionality, coupled with a sturdy feel, makes it great for anyone who prioritizes comfort and high-performance.

The Flip Ultra has a slim and portable form factor manufactured to offer the most comfortable experience. One of the biggest competitive edges for the Flip Ultra is its unique flip feature. Other flipping-style vape pens tend to not have a lock on them. This oversight leads to battery loss and even leakages. O2 Vape solved this problem with a simple lock.

When I was using the Flip Ultra, I enjoyed a consistently smooth vaping experience regardless of which oils I used. Another great feature of this vape is the pass-through charging, which keeps you vaping. I had such a good time that I’ve even started using the Flip Ultra as my primary cart battery.

Despite the fantastic vaping experience, I still have a few grievances. One of the main drawbacks of using this device is that it doesn’t allow you to use larger or oddly shaped cartridge. You have to make sure any cartridges you buy are the specific size to fit in with this vape. Even though this wasn’t much of an issue for me, some vapers enjoy using new and unique products, which might be difficult with the Flip Ultra. Another issue is the keychain slot on the device. While this is a nice little feature offered by the manufacturers, the problem is that it is too big to provide a comfortable fit with most keys.



If you are in the market for an efficient THC vape, you should look at the Flip Ultra by O2. It’s stunning design coupled with features such as consistent output, long-lasting battery life, and voltage variability make it an incredible option if you’re looking to upgrade your vaping setup.

The Flip Ultra is one of the most technologically advanced vape pens being offered by O2 Vapes at the moments. It is becoming increasingly popular in the market, and it has even become my primary cart vape pen as well. The incredible form and features of this vape pen will be hard to imitate in the future, although many competitors are sure to try.
