O2Vape Flip Ultra Review: A THC Oil Vape that Flips With Authority

Product intro and specs

This is the first product I have ever reviewed from O2Vape, but I’ve been seeing them around for some time now. They are best known for their key fob style batteries, vape pens and refillable oil carts. Today we are looking at their most advanced device yet called the Flip Ultra. It looks like a cross between a key fob and a miniature vape mod.

The device stands at about 3” tall, 0.5” thick and 1.5” in width. It weighs in at approximately 75 grams with a full one-gram cartridge. It also has a 650 mAh battery and features both a micro USB and a lightning charging port. The Flip Ultra is an appropriate name for this device. It flips on automatically when the cartridge pops out, which activates a large digital screen. The voltage is adjustable in 0.1 increments from 2.7 to 4.8 volts. I’m curious as to how it compares to the best 510-threaded vapes we’ve tested in the past.

The Flip Ultra was sent courtesy of O2Vape for the purpose of this review.

Price: $54.95 ($99.95 for 2, $225.95 for 5)

Build quality and design

The Flip Ultra looks very modern and sleek. It’s bigger than an actual key fob, but smaller and lighter than a vape mod. It has an attractive matte black rubber finish. It also has a tiny loop in the corner to hook on your key ring. The cartridge really flings out with authority! As soon as it comes flying out, you’re ready to rock. Be careful when flipping it out in public, it can be mistaken for a tiny switchblade.

The screen turns on automatically and turns off when you click the cartridge back in place. The screen is very bright and easy to read. It will catch you off guard if you’ve never seen an oil mod with a digital display before. The screen displays battery life, voltage, and a puff counter, which is useful for monitoring how much THC or CBD you are taking in. The Flip also has a locking mechanism to prevent it from opening up and turning on (or accidentally firing in your pocket,) which protects your oil and battery life.

So far it works with all of the oil cartridges that I tested it with, including various CBD and THC oil carts. O2Vape recommends the slimmer style cartridges for this device, which is the main limitation I have found with it. Otherwise, it can accommodate most 0.5 and 1-mL carts without issues, and those are the most common oil cart sizes. The kit includes a 0.5 mL cartridge, which can be used as a size comparison for compatibility.

The Flip Ultra also has two charging ports. One of them is your typical micro-USB charging port and the other is a lightning port. If you own any Apple products, then you probably already have one. This lets you reduce the amount of wires lying around (even though everything is moving towards USB-C these days,) but two ports are better than one. Sure, it’s a bit gimmicky, but if it saves time in the long run then that’s a plus. It will not charge 2x faster if you plug both cables in—unfortunately it doesn’t work that way.

How to use the Flip Ultra

The device features three buttons and a locking switch. The big protruding “flip” button that releases the cartridge and the locking switch are both mechanical. Other than that there is the fire button and one button to adjust voltage, and that’s pretty much all you need to know.

To release the 510 connection, just press on the protruding button on the upper left side of the device, just above the Flip Ultra logo. Now you can attach your cartridge. Here are some useful tips for using it:

  • Flip the cartridge out by pressing the flip button in the upper left corner of the device.
  • The device turns on automatically when the cartridge is flipped out.
  • The smaller round button cycles through voltage in 0.1-volt increments.
  • The larger round button near the screen is your fire button.
  • To turn the device off, click the cartridge back in while holding the flip button.
  • You can manually lock the device by using the switch on the back.
  • To reset the puff counter, press the fire and adjustment buttons two times.

Performance

The Flip Ultra provides more than enough voltage for all the oil carts that I’ve tried. Anything lower than 3.7 volts just feels a bit weak—that’s just the standard voltage for most stick batteries. I tend to enjoy vaping my oils and distillates between 4 and 4.2 volts for a strong puff, or 3.7-3.9 volts for a more milder one. It goes all the way down to 2.7 volts, which is extremely low, but I can see it being a good feature for lightweights. I tend to cough more on the higher voltages, but none of the hits have been unpleasant.

One advantage that the Flip has over your typical pen-style battery is that the power output is consistent. It seems to be putting out the same voltage on a low battery as it does on a full charge. The battery life is also at least double, if not triple the capacity of most stick batteries, so it really has the potential to hold you over for a while.

I was able to get many sessions over the course of a week on a single charge. If you’re puffing on some high potency distillates, you probably won’t be running out of battery life so fast. It also does pass-thru charging, for people who just can’t stop puffing.

Pros / Cons

  • Discreet design
  • Sturdy construction
  • Great flipping feature
  • Locking mechanism
  • Turns on and off automatically
  • Bright display with puff counter
  • Good battery life (650 mAh)
  • Dual charging ports
  • Pass-through charging
  • Doesn't accommodate wider carts
  • Too bulky to use as a keychain

Verdict

The Flip Ultra is a handy tool to have in your arsenal. It has a discreet design that conceals your cartridge, and protects lint and dirt from getting in. The way it just turns on and off automatically is a nice stoner-friendly feature that can conserve battery life in the long run. I also appreciate how it locks into place with just the flip of a switch. As for the price point, it’s actually cheaper than a lot of oil vapes that lack most of its features.

I had to get extra picky when looking for cons for this device. Apparently, there are a few wider-than-average carts that lack compatibility with it. It’s also a bit impractical to use as a keychain, at least by my standards. Aside from that, there is not really much for me to complain about in terms of its actual design and performance. And even though I haven’t been using it for long, it seems like a resilient vape that can probably survive a bit of wear and tear. I only dropped it once, and both the device and the cartridge went unscathed. It happens to be covered under a lifetime warranty, so it’s set for life.

I would recommend the Flip Ultra to oil vapers who want something inconspicuous that doesn’t need to be charged so often. I think O2Vape was successful at creating a vape that excels in functionality and aesthetics. Everything about the design actually serves a purpose, it’s not just trying to be fancy to show off.
