Design & Features:
As similar to other O2VAPE (Visit Store) products we’ve seen, such as Dryonic II for dry herb (Review | Buy) and Cream-X for concentrates (Review | Buy), the Flip Ultra is exclusively manufactured for O2 brand in a unique design.
The Flip Ultra solves a portability issue common in other 510 vape batteries, traditionally shaped as a long narrow pen and can accidentally break or turn while being carried or worse, sit on (yeap, been there). The Flip is shaped like a small square, bigger than a key fob, and smaller than a traditional dry herb vape. It stands about 3inches tall and 1.5inches wide and weighs 75 grams, making it very compact, easy-to-carry and discreet.
The Flip feels silky and stealthy when holding it in the palm of your hand. It has a matt rubber finish that after reading some users reviews, I repeatedly came across the claim that its edges are peeling after only a few weeks. So far I’ve been using mine for around a month, and have not seen signs of that, I will come back here and update this changes.
As the name suggests, the cartridge is folded in the device and flips out when you push the button, just like a car key. Another innovation we see here is a flip-lock mechanism that will allow you to secure the cartridge while in your pocket so it wouldn’t accidentally open. I love this feature since, again, it makes the Flip more portable and less fragile than other vape pens out there.
Flip Ultra comes with the brand’s 510 Cart in Gunmetal that you can fill in, but it is compatible with most 510 thread oil cartridges, which is the industry standard.
The Flip will automatically turn on when flipping out the cart, instead of traditionally pressing the button five times. Accordingly, it will disable when closed. If you like taking quick random hits when on the move, you will find this feature very useful, especially as the Flip is instantly ready to use and doesn’t require preheating time.
The Flip features a precise temp control of a wide voltage range of 2.7V to 4.8V. The lower levels are usually aimed for users who are looking for a soft, mild vapor. We’ll get to the ideal voltage level for most users later.
The desired voltage is set via the smaller button, on the right side of the screen, in 0.1V increments.
when flipping out the cart, the digital screen will come to life, displaying the voltage level, battery life, and a puff counter. The puff counter is useful for users who want to follow their THC/CBD consumption throughout the day or track a cartridge lastingness. Resetting the puff counter is done by clicking both the big and small buttons twice simultaneously.
Flip Ultra powered by a 650mAh battery that will easily last a couple of days for most users. Since oil pens typically don’t consume energy as much as dry herb vapes or wax pens, the battery is not only enough but will probably outlast longer than 0.1 carts.
510 threads usually need to be screwed to the charger, but not the Flip; it has both a standard micro-USA port and a lightning port that allows you to use your phone charger.
Performance & Vapor Quality
Flip Ultra is an on-demand device; once you hit the cart-releaser button, the cart will fly out ready for immediate vaping. I prefer to preheat the oil first to make the most out of my CBD cart and even though O2vape claims that preheat is available by clicking the button for a few seconds, I didn’t feel any different when hitting it.
The vapor quality is largely affected by the cart oil you’re using, but the voltage setting plays a big role here too. Each cartridge will probably perform best at a different voltage level, but I found the sweet spot for most of them somewhere between 3.7V and 3.9V.
The lower settings produce milder vapor and more robust terps flavor and can be used for discrete sessions. For a firmer and more intense session, use the higher settings; the 650mHa battery can deliver an impressively powerful experience.
Flip Ultra features some cool characters like dual-charging options, long battery life, and precise temperature. Its price and lifetime warranty makes it a safe choice for users looking for a 510 thread battery for traveling and outdoor vaping. One thing needed to acknowledge is the cartridge size, as wider carts may not fit in the small cart niche.
The built quality and material long-lastingness are worth exploring. Even if you have a lifetime warranty, you wouldn’t want to deal with warranty activation and wait for a new one. With that being said, the Flip Ulta still has more highlights than drawbacks, and for that reason, I recommend it with respect.
