Pax 2 vs Firefly Vaporizer Comparison

pax 2 vs firefly vaporizer comparison

This will be a comparison between the Firefly and the new Pax 2 portable vaporizer. This Firefly vs Pax 2 breakdown will show why each one of these portable vapes could be someone’s favorite. Both offer different qualities that separate them apart.

Update: The Firefly 2 is now out (available for pre-order $329, shipping May 2016) and the Firefly 1 will no longer be manufactured/sold. I also finished up my comparison of the Pax 2 vs Firefly 2. The Firefly 2 is a much improved unit over the original Firefly. The Firefly 2 is much smaller, lighter, offers 5 dry herb and 1 concentrate temp settings and comes with two batteries! Each of the batteries are getting me between 4-6 bowls on average and they charge via the charging dock in less than 50 minutes. The main issues of weight, battery life and overall ease of use have been fixed. Click the link above to check out the full review.

Pax 2 vs Firefly Continued…

The Firefly is nearly on demand heat with great vapor production/quality and the Pax 2 is one of the smallest, lightest, and consistent vaporizers out now. The Pax 2 is a HUGE improvement over the original Pax and has eliminated the cleaning/maintenance aspect by 80-90%. PaxVapor has been an industry leader in the vape niche for close to a decade now and Firefly is the up and coming contender.

The Firefly is the only PURE convection portable vaporizer currently on the market. Others will make the claim but none can do it like the Firefly. The unit is a bit bulkier because of the stainless steel design but still pocketable and produces great vapor quality.

The Pax 2 retails for $279 and you can get the Firefly for $269. Click here to check out the best price on both from an authorized retailer.

So let’s get into the details and break down some of the differences between the Firefly and the Pax 2.

Pax 2 Firefly Vaporizer ComparisonSize – The Firefly is definitely the bigger unit weighing about 241 grams while the Pax 2 wieghs around 92 grams. The external dimensions of the Pax 2 are 3.87”H x 1.21”W x .085”D while the Firefly is 5.5”H x 2”W x .85”D.

I can still travel with my Firefly (and I still do) so the size isn’t that big of a deal but the weight is a really big difference. I can still get the Firefly in my short pockets during the summer months but it definitely weighs me down. I know it’s in my pocket and it’s taking up room where my cell/keys would be.

It’s completely the opposite with the Pax 2. You won’t even feel the Pax 2 in your pocket. You’ll have to keep checking to make sure it’s still there in between sessions. I’m really impressed with how much size they were able to cut down.

They completely removed the mouthpiece design and placed the on/off – temp select button internally so it’s NOT in the vapor path. This also completely removed the mouthpiece all-together. The new design sits flush along the top of the unit which makes concealing it even easier than the previous model.

Pax 2 Firefly Charging SystemsBatteries – The Firefly uses a replaceable high powered li-ion battery with no USB charging whereas the Pax 2 does off USB charging but the batteries are NOT replaceable.

This really comes down to preference and you can make either work. Personally I’m a fan of the USB charging because I just picked up an Anker battery pack which will charge my Crafty, Pax 2, PUFFiT 2, etc.. all while on the go.

On the other hand, you can just pick up an extra battery or two for your Firefly and easily swap one out in seconds (literally).

Battery life is really the only difference in this category and the Pax 2 comes out on top with about 70+ minutes of continuous average use. The Firefly is down around 45 minutes which isn’t the best. Firefly IS releasing some new more powerful batteries which they just got in stock and should add +15 minutes or so.

The Firefly will completely recharge the battery (from dead, in the unit) in about 45 minutes which is one of the fastest charging batteries currently in a portable. The Pax 2 will take about 90 minutes to fully recharge. NEITHER unit has pass-through charging (use while charging).

Firefly also offers an external charging dock which will let you charge a batter outside the unit.

*Bonus – PAX 2 can be charged with the charging dock from the original Pax and it cuts the charging time by about a ¼ which is pretty cool.

The Chambers, Heating Elements and Vapor Paths – I rate both of these units in the top three as far as heating techniques and vapor paths, the Firefly being the very best in terms of vapor quality.

Pax 2 Firefly ChambersThe Firefly uses an all glass heating chamber and a stainless steel vapor path to achieve cool but dense vapor. I’m able to get about .15 grams in the chamber with the Firefly and that’s plenty for 1-2 people to be heavily medicated.

The best feature about the Firely is the nearly on demand heat up. I can literally pull out the Firefly, pre-heat the bowl and take a draw before the Pax 2 finishes heating up. So if you are someone that needs quick sessions and it’s only going to be 1-2 people then the Firefly is probably your best bet. The smell is a lot less with the Firefly than the Pax 2 because of the convection style heating so that’s also another nice feature if you need quick, inconspicuous sessions.

The Firefly is still a big unit so you won’t be too inconspicuous but at least you could be out on a smoke break for a minute or two, hit the Firefly, and be back inside. The Pax 2 would still be cookin herbs on the way back in producing odor and warm in the pocket.

The Pax 2 is definitely a session vape and I really feel like the Pax 2 shines for activities like festivals, camping, hiking, concerts, or anytime you have a big group of friends with you. The PAX 2 has a good size bowl and longer battery life, you can session the Pax 2 for 15+ minutes if you wanted to and just get 3-4 people smashed. You can’t do that with the Firefly.

Pax 2 Firefly Vapor PathI was able to get ~.2grams in the Pax 2 chamber using my Santa Cruz Shredder. I was able to get ~.4grams when using my MFLB Finishing grinder. Now I packed it down pretty tight so I don’t really recommend this but I do recommend that you use/pick up the MFLB Finishing Grinder to use with your PAX 2. It really helps produce much denser clouds and an even vape of your herbs. Ramps up the cleaning a bit but it’s worth.

The Pax 2 uses a stainless steel oven and vapor path.

*Firefly Concentrate Pads are out now and they work really well. If you have a Firefly already or going to be picking one up soon then I recommend adding the pads to your order. It’s extremely easy to use and it tastes sooooo good.

Cleaning & Maintenance – Overall, both these units are extremely easy to clean.

The Firefly can basically just be wiped down after a use while the oven/lid are still warm and it stays clean. Maybe once a month I’ll put some ISO on a paper towel and wipe down the stainless steel vapor path on the inside and take a Q-Tip to the bowl. The window on the lid does get dirty pretty fast but it doesn’t hinder the device in any way, you just can’t really see the herbs clearly so I try to keep that clean.

The new Pax 2 is a HUGE improvement in the cleaning/maintenance compared to the original. It definitely gets dirtier faster when using a finer grind but all you have to do is dip the pipe cleaners in some ISO (both included now) and clean the vapor path. You can take a Q-Tip to the oven/screen and that’s it.

Overall I would still say the Firefly is the easier to maintain and clean.

Summary – I hope that I could do a good enough job of explaining the pros/cons of each of these vapes. Both the Firefly and the Pax 2 are very good vaporizers and like I mentioned above, each could be anyone’s favorite.

Personally, if I had to choose one or the other at this point, I would probably go with the Pax 2. IF it was my ONLY vape. Just because I know that at some point in time I’m going to want to be inconspicuous about just what it is I’m doing with the strange device I’m inhaling from. The Firefly screams look at me which is cool if you can get away with that but the Pax 2 is definitely much more discrete/concealable.

Story time: I took the Firefly out to Wayfarer State Park last year and I was just takin small draws throughout the day while floating with friends. The married couple next to us look over on the way out and was like “nice smoke piece guys”. They were super friendly and were genuinely interested in the Firefly I think but my point is people see it. It’s a flashy device and has a bit of size but it does do the job extremely well.

Had we been using the Pax 2… they might not have even seen anything at all or passed it off as an e-cig device.

    Great job thank You. I made My mind and you won a suscriber. Win-Win. :)

    Hi Buzz! I’ve been reading your reviews for a while now and have decided that I am torn between the Pax 2, Firefly, and the Crafty. Help!
    I’m pretty new to the vaporizing world and would love advice.
    Discretion isn’t the most important to me, but I really love the way the Pax 2 looks. However, my tolerance is pretty low and am worried that the Pax 2 wouldn’t be as efficient as the Firefly in my situation – I can’t quite go through a whole bowl in one sitting by myself. I’m quite fond of my mflb for this reason, and love that I can work on a single bowl all night if I want to.
    I really admire the vapor quality produced by the Crafty but am somewhat turned off by the straw and overall industrial/bulky appearance. What I am looking forward to in an upgrade is something that will let me sip slow all day on some days and get to a quick 10 on others.

    • Buzz Danklin says: May 26, 2015 at 1:52 pm

      I think the Firefly is the best option for you, it is similar to the MFLB, but more more powerful. A good Firefly draw will be much more potent (and tastier) than the best stacked mflb draw I can do. The Firefly works really well for splitting a single bowl into multiple sessions because it heats up and cools down so quick.

  • D to the B says: July 9, 2015 at 9:05 pm

    I really, really enjoy your reviews. So many “reviews” online are just really advertisements in the end. I have been wanting to get a portable vape I can also use at home with ease, since I have owned a Vapor Bros. for years, but as you may know, is hardly portable.

    For now I will go with the Pax 2, for I love the size, and how inconspicuous it is. I hate the price, but I’ve heard nothing but good things about their customer support, warranty and all that jazz, so if it does last me 3, 4 or even 5 years, that’s worth the cost.

    Thank you for such a great product comparison, and I also truly love your videos. They are great! One thing though – quit filming in front of those gorgeous mountains you bastard! It makes me miss the days I used to always come out to Colorado for a week of camping and Widespread Panic at Red Rocks. :)

      Thanks so much for the kind words!! Let me know how you like the Pax 2.

  • Laura says: August 16, 2015 at 1:59 pm

    Thank you for your excellent reviews! I’ve been searching all weekend, Finally able to make a decision after reading yours. I’m going to order the Firefly- and I’m wondering whether you have a preference/recommendation for which grinder works best with this ?

    • Buzz Danklin says: August 16, 2015 at 9:56 pm

      I would go with the Santa Cruz Shredder or the Space Case. Let me know how you like it!! Glad I could help.

  • Chrissy says: August 21, 2015 at 5:22 pm

    Sweet review, I was really going back and forth between the two devices but your story at the end sealed the deal. Since I have small hands and generally don’t have lots of room in my pockets, the Pax’s discrete look is definitely more suited for me. Great site, can’t believe I haven’t seen it before. Will be keeping up with your posts from now on :)

    • Buzz Danklin says: August 21, 2015 at 5:38 pm

      My pleasure! Glad I could help you out. You can check me out on instagram too! I post stuff more regularly there.

        Hey Buzz,

        Just wanted to let you know that I got the Pax 2 a couple months ago and it’s amazing. I love the length of the sessions, one minute I feel normal wondering when it’ll kick in and the next I can barely move it hits so hard. Even the draw resistance is a plus because it forces me to go more slowly, which is easier on my lungs. The vapor quality is great, but you were right about the first couple draws tasting the best. Also got the SCS per your recommendation, which is the best grinder I have ever had the pleasure to use. All thanks to you. Thanks for these kick ass reviews! PS I checked out your instagram; you lead a good life, my friend

        • Buzz Danklin says: November 16, 2015 at 3:57 pm

          Wow Chrissy, thanks so much for the kind words and checking out my site. I always try to provide the most honest reviews because in the end you guys are all the matters. I agree the Pax 2 is quite the vaporizer. I will be using it a LOT up on the slopes this season. Stay in touch Chrissy and let me know if you have any more questions! Take care.

  • Cheryl Phelan says: September 11, 2015 at 5:52 am

    Hi Buzz…just discovered your site yesterday while anxiously waiting for my new Firfly to arrive in the mail:) My husband Jack & I tested it out as soon as the battery charged (bought an extra one also). Tried to put all your tips into use. Definitely got medicated! Not a lot of visible vapor exhaled but I hear it’s just wasted if you do see any come out. Trying different amts and grinds to see what’s perfect, concurring with you advised.. Noticed more vapor (smoke?) when I heated again what seemed like brown, finished product …that’s why I thought it might be smoke. With my MFLB (bought a finishing grinder too for that and love it, but not for FF like you said, for sure!) I get an unpleasant taste that tells me the bow’ls finished but I don’t get that crappy taste with the FF so it’s harder to tell. Practice and time will help me figure that out I guess. Thanks for the great videos. I’m jealous of you sitting in front of those mountains too, but worth it to see them☺️ and to know you are enjoying them. Thanks as well for your helpful website.

    • Buzz Danklin says: September 11, 2015 at 2:42 pm

      Thank you so much for the kind words!!! I’m glad that you are enjoying the FF and yes it does kind of require a technique. Similar to the MFLB. The pre-heat is always the best tip I can give. With a fresh bowl, hold down the heat button and let it pre-heat for about 6-8 seconds and then try to draw for the remaining heat session. I think it’s 30 seconds total. The longer you draw for the more of the visible vapor you will see which isn’t a bad thing.

      Different temps trigger different parts of the plant and as you draw longer, the temp will increase in the chamber. Let me know if you have any other questions or suggestion for videos/reviews. I’m always looking for feedback! Thanks again Cheryl, have a great day :)

      • Cheryl Phelan says: September 26, 2015 at 7:10 am

        Thanks Buzz! After enjoying thoroughly, our Firefly, we are now eagerly anticipating the arrival of a new Pax2! While loving the yummy flavor and buzz it sucks for some things. We were out last night at a stage show and during intermission went out for a “pick me-up”. It was dark and hard to make sure the magnetic top fit securely as particles of product love to stick to the slightly sticky surface. Kind of a pain…but happy that the battery lasted 5 bowls, so didn’t have to swap it til we were headed home, but definitely good to have a second one on hand. The Pax2 should be a longer lasting unit battery wise, not need refilling so often, and be more discrete for taking on our bike rides. The Firefly will be our go-to home preference for the great taste; the Pax2, our on-the-go one. Think that should work out just fine! Thanks again for your reply. Peace and great health to you.

        • Buzz Danklin says: October 2, 2015 at 12:13 pm

          Hey Cheryl!! I’m glad that you are loving the Firefly, I still pull it out every so often and it blows me away with just how hard it can hit. You are right that it requires some finess to pack it right and make sure that you dont get any herbs along the rim of the bowl. You will absolutely LOVE the battery life on the Pax 2 and the overall portablilty is the best on the market. It’s so easy to conceal if needed and the session experience is nice for two people.

          Thanks for the kind words and I’m looking forward to hearing about your Pax 2 experiences.

  • Jon Detter says: September 29, 2015 at 2:00 pm

    Buzz, in need of advice. First off, great review. I am looking to get my first vape and have narrowed it down to the pax 2 and firefly. Usually it is only my girlfriend and I, so sharing amongst a lot of people is not a concern. We are always on the go, but usually only smoke somewhere that is isloated and safe to do so such as parks, the car, etc. We are not everyday users, I would say 2-4 times per week. We will be only using which ever vape we get, instead of smoking, so it will get a lot of use. Just not sure which one is right for me, I am a very picky consumer, lol. Any imput or advice would be appreciated. Thank you.

    • Buzz Danklin says: October 2, 2015 at 12:06 pm

      I think you are going to want the Pax 2. It’s a great session vaporizer for two people and you can’t beat the battery life. The Firefly is nice but the battery life isn’t the best so you are having to bring along an extra battery if you guys decide to go out hiking or go to the parks for the day.

      With that said, I can usually get about 3 chambers full (barely) before the battery dies on the Firefly so if you think that would be enough for you guys for the day then that might work. I really like the Firefly because of the quick heat up times, (10 seconds with pre-heat) and the flavor that you can get from the pure convection heating method. It’s also much heavier than the Pax 2 and a much more flashier device.

      You could easily palm the Pax 2 for concealment if you needed to and overall it’s just much easier to store in pockets and carry around out on the go. So yea, I think you’re going to want the Pax 2 but let me know if you have any more questions and i’ll help you out.

  • Don Juan says: October 6, 2015 at 9:57 am

    Hi, which would you say is more “efficient” with herbs? I am a single guy, and currently smoke a bowl after work, and another right before bed. Which do you think is best for me?


    • Buzz Danklin says: October 19, 2015 at 2:01 am

      I would go with the firefly or the Grasshopper. Let me know which one you decide to go with or if you have any more questions. Have a good day.

  • Don Juan says: October 6, 2015 at 1:49 pm


    I have a question regarding efficiency. I pretty much smoke by myself, and a bowl is all it takes to get me medicated. Which would be more efficient, the grasshopper, the firefly, or the pax 2? Thanks

    • Buzz Danklin says: October 19, 2015 at 1:53 am

      The Pax 2 is much improved over the original Pax but I still think the Grasshopper is a little more efficient still. Plus the near instant heat up time is why I like the Grasshopper over the Pax 2. Quick sessions and medicated quickly. Both are good with any bowl size for different tolerances.

  • Cynthia Manchester says: December 30, 2015 at 6:33 pm

    Could you advise me which vaporizer would be ‘healthiest’ – in terms of vaporizing only product and not heating anything plastic. I am using this to deliver medication (autuimmune disease) and want to avoid inhaling heated plastic at all costs. I have a DaVinci Ascent which I haven’t mastered yet… I am particularly interested in vaporizing concentrate. Many thanks for your kind help!

    • Buzz Danklin says: January 14, 2016 at 9:11 am

      If you don’t need a portable unit, I would check out the Volcano vaporizer. It’s a desktop unit but proven to deliver some of the purest form of thc through a bag delivery system. If you want to stick with a portable, I would go with the Firefly but I would hold off for a couple weeks because I believe the Firefly 2 will be out in the next few weeks. Don’t quote me on it though.

      The Firefly is one of the only pure convection vaporizers and produces extremely good vapor quality. The Firefly 1 is a pure stainless steel vaporizer with an all glass bowl and stainless steel vapor path. Only downside is the battery life and it requires a little bit of a packing technique to get the best results. The Firefly 2 does a much better job with varying load sizes so it won’t be as hard to pack as the Firefly 1.

      I really think the Firefly is going to be your best bet but I personally would hang on for a couple weeks and see if they Firefly 2 will be here and pick one up. It will be everything you are looking for. :)

      • westcoastvaper says: April 4, 2016 at 10:25 pm

        The Firefly 2 is coming out at the end of May 2016. I really wish it was out now. People want dry herb vapes that are super efficient and palmable. The Mighty and Crafty do good jobs but they have a poor track record as far as warranty and customer service. The Pax 2 has some aftermarket items that make it nicer to use. I think I’m going to pick up one of them instead of waiting until the end of May!
