Choosing between the Pax 3 and the Arizer Solo 2 is no easy task. Their feature lists are as equally impressive as they are different. I think that we can all agree that having both would be better than having to pick between them, but the sad reality is that getting a premium vaporizer like these two is a big investment, so you’re going to have to make some choices. We want you to get the perfect portable for you needs, so today we’re going to compare these two head to head to see which one is deserving of your hard earned money…


Vapor Quality

Pax 3

The Pax 3 Vaporizer is a fully conduction unit, but as we’re learning with the newest generation of vaporizers, that’s not necessarily a bad thing. While convection heating typically delivers better flavor, you can still get excellent vapor out of a conduction unit. The Pax 3 is a great example.

There are a couple things that I think really help the vapor quality from this. The first is that the chamber is located on the bottom of the unit, which means it has more time to cool before reaching your mouth, throat and lungs.

More importantly though, this is an extremely “smart” vaporizer. One of the biggest problems with conduction heating is that all the best vapor and flavor usually burns off too fast because it’s constantly heated, so the first few draws are typically great but followed by a steep drop off in quality. The Pax 3 has sensors that are used to track how the device is being used, so it will actually cool down in between draws. This is all done behind the scenes with no input from the user at all.

Long story short, you’ll be getting better vapor for longer than with any of the earlier Pax models, and the Pax 3 holds its own against some of the best vaporizers on the market.

Arizer Solo 2

While the Pax 3 may offer very good vapor that performs respectably against other premium vaporizers, there’s also no denying that the Solo 2 offers objectively better vapor. It’s cooler, smoother, and more flavorful, and the vapor density is pretty much the same.

There’s a couple reasons that the Solo 2 is able to outperform the Pax 3. The first is that it relies on a blend of convection and conduction heating. This means users get the best of both worlds, which translates to dense and flavorful vapor over the duration of a session.

Speaking of, one of the best parts of the Solo 2 is the efficiency. Like the original Solo, the Solo 2 continues to deliver high quality vapor long after you would normally expect the chamber to be spent. I’ve never seen a single chamber pack last for as many draws, especially which such good flavor throughout.

The other reason that the vapor is so good is the long glass stem. This gives the vapor ample time to cool down, which translates to very smooth draws, even at higher temperatures.



Vapor Quality Winner: Solo 2

I already started to mention some of the new features of the Pax 3 in the vapor quality section. These sensors, which are accelerometers and some method of knowing when your lips are on the mouthpiece, make it one of the most advanced vaporizers on the market in terms of technology. The other one that comes to mind is the DaVinci IQ.

The battery of the Pax 3 was also updated to 3500mAh. I get a little over an hour and a half out of every charge, which is about 10 sessions. The Pax 3 still doesn’t have full temperature control unless you pair it with the app. From the device itself, you can only choose between four settings.

The appearance hasn’t changed much since the Pax 2, although the exterior now has a glossy finish. I like how it initially looks, but it is also very easy to scratch.

Arizer Solo 2

The Solo 2 also has a bunch of new features worth talking about when compared to the original Solo. There are two that really jump out in my mind. The first is the digital screen and full temperature control. If you like being able to choose the specific temperature that you vape at, you’ll appreciate this a lot.

The bigger improvement is definitely the battery though. The Solo 2 is capable of around 3 hours of use on every charge, which is about 20 sessions! This is a game changer in my book as it’s easily double what most vaporizers offer.

Only time will tell, but I also expect this to be one of the most durable options on the market. If it lasts anywhere near as long as the original, I’ll be happy!

The Pax 3 is pretty much the king of portability. It’s a small cylinder-like shape and can be used without a mouthpiece elevated above the base. Of all vaporizers that I’ve used, this is probably the most comfortable when carrying in your pocket.

The fact that there is no glass or displays also means that it can handle a good deal of bumping around things in a purse or bag without breaking. The battery life is also above average.

The only complaint that I can think of is the fact that I scratch it on things like keys all the time. I’ve just learned to accept the fact that there’s no way to keep it as pretty as it is when you first open it.

Arizer Solo 2

The Solo 2 has limited portability. It’s great for using around your home or taking it to a friend’s house, but it’s not a good option for carrying with you throughout your day.

The base isn’t a bad size, it’s the glass stem that’s inconvenient. You can’t carry it connected to the base, which means you have two parts to take with you.

The fact that it’s galss also means that it’s easy to break. On the plus side, you do get a carrying case and the battery life is ridiculous. The Pax 3 is the obvious winner here.



Portability Winner: Pax 3

The shape of the Pax 3 makes it incredibly easy to conceal in your hand. The flat mouthpiece is also extremely discreet because it makes the unit not look like a vaporizer to people who don’t know what it is.

I’d guess people would be more likely to think it’s some type of music player than a vape, actually.

Once again, the glass stem hurts the Solo 2 in this category. I’m not complaining about the glass stem, because I like the performance it delivers in the vapor quality section.

I’m just stating a fact, which is that the stem will always be visible when you are using this. Once again, the Solo 2 is a great option for using at home but not so good while out in public.



Discreetness Winner: Pax 3


Winner: Arizer Solo 2

This matchup was technically a tie, but I think the Solo 2 is the better overall vaporizer. It’s a tricky call to make though because they excel in very different categories.

The Solo 2 is an absolute beast in two very important areas: vapor quality and battery life. The vapor it produces may actually be my favorite of all portables when you factor in flavor, smoothness, density, and session length. There are others that can beat it on flavor or density individually, but the Solo 2 offers the perfect blend. When it comes to battery life, the Solo 2 also destroys the competition.

The Pax 3 puts in very respectable performances for vapor quality and battery life, but really shines when it comes to portability and discretion. That’s why it’s tough to call one of these better than the other in absolute terms.

If you’re looking for a vaporizer to use around your home, the Solo 2 is likely the best one you can get.

If you’re looking for a vaporizer to use with you throughout the day, the Pax 3 is an excellent option.

All you have to do is figure out what you’re looking for, which is something that I can’t help with unfortunately!

If you are thinking of picking up a Pax 3 or the Arizer Solo 2, we recommend grabbing them from, they have no tax and free shipping on orders over $100.
