The Firefly 2 is an on-demand portable vaporizer manufactured by Firefly Vapor. It’s one of those vaporizers that will fulfill the naughtiest dreams of any true connoisseur (or flavor-Nazi in layman’s terms).
When the original Firefly came out in the end of 2013, it hit the market as one of the most revolutionary portable vaporizers ever made…
Before the Firefly, a PORTABLE (and electronic) vaporizer which is 100% convection-based, was basically something out of fairytales…
But a PORTABLE vaporizer which is 100% convection-based, AND…
This is crazy:
ONLY has a 10 second heat-up time…was something the most creative and open-minded among us, would not have come up with.
And although it really was one of the most revolutionary portable vaporizers at that time…it definitely was not for everyone because it had some issues and shortcomings like:
- Unreliable battery performance;
- A steep learning curve;
- Its big size and;
- Heavy weight.
With the Firefly 2, Firefly Vapor made an attempt to improve their original namesake vaporizer…attacking all of these issues and shortcomings HEAD-ON.
The question is:
Were they able to?
Continue to find out.
Or go straight to the pros and cons and conclusion:
Where to buy the Firefly 2:
Holding the Firefly 2 in your hand…
You will quickly realize what an elegant piece of art this thing actually is…it has ‘quality’ written all over it.
From the leightweight die cast magnesium body, to the well designed magnetic lid…everything about this vaporizer feels highly modern and luxurious.
Even the gimmicky touch sensors with which you operate the unit feel very modern, and actually work surprisingly well.
The inside of this vaporizer is highly premium as well…its vapor path is fully made from gorilla glass. This is unique, I don’t know any other portable vaporizer with a gorilla glass vapor path…AND protects its glass vapor path with a sturdy metal shell.
The Firefly 2 shows a glass vapor path and sturdiness can actually go hand in hand.
Size & weight
While the original Firefly was a bit too large and especially too heavy to be a true pocket-vape…
Firefly Vapor not only reduced the size of the Firefly 2 by 33%, but reduced the weight by a whopping 55%, compared to its predecessor.
How did they do this?
They basically replaced the stainless steel body of the original Firefly with a body made of die cast magnesium, which obviously is more lightweight than stainless steel.
So how big and heavy is the Firefly 2?
Its weight is 0.24 lbs (108 g), which is more than acceptable for a portable. While the original Firefly kind of felt like a burden in your pocket (0.53 lbs / 240 g), the Firefly 2 feels alright. Not as lightweight as the PAX 2 for example but definitely does not feel as a big burden. I actually can fit it in the same pocket as my phone (Nexus 5X).
So although it’s not the most stealthy or discreet vaporizer in terms of its size, it won’t stand out like a sore thumb when you pull it out either.
And the point is:
You won’t have to pull the Firefly 2 out for a long time, because its heat-up time is 5-10 seconds (yes you read that right).
Discreetness of design
Its design and the way you hold it while inhaling also give the Firefly 2 extra points on the discreetness scale. I’ve told people it’s an asthma device before and have been asked if I was testing my alcohol percentage while sucking on this thing.
What I mean is this:
People don’t really associate the size, shape and operation of the Firefly 2 with vaping weed.
You might be afraid of weed odors coming off of your vaporizer…
You don’t have to be afraid, if you keep the lid closed. If you open the lit, it’s smelly like any other vaporizer with an open bowl.
But with the lid closed…the Firefly 2 is in fact the LEAST smelly portable vaporizer I’ve ever tried, especially during use.
So in that sense it’s definitely super stealthy and discreet.
The battery life is nothing special, but decent. I usually get around 5 bowls with 12+ draws per bowl (these are full bowls). The batteries are swappable and you get an extra battery when you purchase your Firefly 2. That’s definitely a big plus.
Heating element and air path
The original Firefly is the only portable vaporizer I know of, that has a glass encapsulated heating element.
And Firefly Vapor continued this amazing feature in their second version of their namesake vaporizer.
The best part?
While the original Firefly had a stainless steel vapor path, Firefly Vapor decided (except for the plastic mouthpiece) to design the second version of their vaporizer with an all-glass vapor path.
We are the biggest fan of glass in vaporizers and if I had the power, EVERY vaporizer would have a full glass air path and a glass-encapsulated heating element. You can read here why glass is the most preferred material in any vaporizer air path from a safety standpoint.
The Firefly 2 really is setting a new standard with all that glass used in the most crucial parts of a portable vaporizer. There is no other portable vaporizer that can say this and this is exactly what makes the Firefly 2 one of the safest vaporizers you can get.
Really…Firefly Vapor proved a vaporizer being portable is NO EXCUSE for not having an all-glass air path.
Separation air path and electronics
One safety concern that keeps popping up with any vaporizer…
Is the concern about the air that you inhale passing over the electronics of your vaporizer. No decisive conclusions can be given at this point regarding this topic.
But the initial user tests seem to indicate no such thing occurs.
The bottom line is:
Currently the FF2 is one of the safest, if not the safest, portable vaporizer you can get.
Vapor Potency (7)
Potency is one area where the Firefly 2 is not in the absolute top ranks…
Although it is a 100% convection vaporizer and does produce vapor which is of great potency…it won’t produce the clouds of a MIGHTY or CRAFTY for example (then again which portable vaporizer does?).
So if you’re a cloud chaser the Firefly 2 is not your best option.
If you’re not a thrill seeker and don’t necessarily need your vaporizer to hit you like a truck, the Firefly 2 will be good enough for you.
It WILL get you where you want 100% of the time.
This vape medicates really, I mean really well, with a small amount of herb.
Tip: I noticed with the FF2 especially, if you have moist herb, you tend to get whispy hits. Always try to use well cured and well dried herb.
Tip: Depending on the weed strain your vaping, you might or might not get visible vapor depending on your temperature setting and moisture of your herb. Set the temperature higher and give your Firefly 2 a couple of hits before it starts producing visible vapor.
Tip: Sometimes you just don’t get a lot of visible vapor with the FF2. An easy way to check if you’re getting the goods out of your herb, is to check the color of your herb after 5-6 proper hits. If it still has the same color as when you put it in, there might be something wrong with your unit. Especially if you get this a lot.
Tip: Remember to draw for at least 10 seconds, with quite some power.
Tip: Vapor doesn’t have to be visible for you te feel it.
Vapor Flavor (10)
This is where the Firefly 2 truly shines…
This is the BEST tasting portable vaporizer I’ve ever tried…PERIOD. The flavor is so pure and unadulterated, really…you will be tasting the herb as God intended it to be.
The flavor it produces is not only extremely flavorful…but extremely smooth as well. Even on the highest temperature setting (no I don’t mean concentrate setting, NEVER use the concentrate setting with dry herb) the vapor doesn’t have any harshness to it.
Its long vapor path does seem to be one of the biggest factors to this…it seems to act as a natural cooling mechanism.
But the two (2) main design decisions that make the Firefly 2 the BEST tasting portable vaporizer are the following:
- 100% convection-style heating;
- An all-glass air-path (except for the plastic mouthpiece).
Convection-style heating simply is essential if you want pure unadulterated flavor. And glass is the most inert material that can exist in a vaporizer. Any other material in your vapor path will alter the taste of your herb slightly at the very least.
On-demand and 100% convection
Being a 100% convection, on-demand vaporizer…
The Firefly 2 is extremely efficient by its core design.
Let me explain:
On-demand means your heating element is only active while you’re pushing the touch sensors. And since its heating mechanism is 100% convection based (your herb will get heated through means of hot air)…
…your herb will only be exposed to hot air while your fingers are on the sensor AND you’re drawing. The hot air only gets pulled over your herb IF you draw.
You simply cannot waist any herb in a system like this.
This is exactly the opposite of a conduction session-vape like the PAX 2:
In such a system your herb gets directly cooked by being exposed to the heated surface of the chamber in which it resides. Whether you’re drawing or not, your herb gets cooked. Plus since its session-based, the heating chamber stays warm for at least a couple of minutes…which means you either quickly finish your bowl, or waist herb.
Now add to this the fact that it has a small bowl (capacity of 0.15 grams)…
…and you got yourself what I would say is the most efficient portable vaporizer (butane vapes not included and read here why small bowls tend to be more efficient).
The minimum amount I’ve been able to get a satisfying hit and get medicated with (keep in mind I do have low tolerance) is 0.05 grams. This means one (1) hit can get me medicated. No, it won’t propel me into unchartered psychedelic territories…but I will feel it for sure!
Tip: An easy way to enhance your unit’s performance with small amounts of herb is to put the concentrate pad, or any other screen that fits in the bowl, on top of your ground herb to compress it (keep in mind this does increase draw-resistance, so you’ll have to draw a little harder).
Ease of Use (7)
While the original Firefly had quite steep a learning curve…
It also made it so that once you had the learning curve down…you would have supreme control over the vapor quality your unit produced.
Anyway…here’s the deal:
With the Firefly 2 things have changed up a little…
…for the better!
You still have to take care of your drawing pattern:
- Don’t draw weakly…suck relatively hard;
- Draw at least 10 seconds to get proper vapor production.
But it has definitely improved over the original Firefly where how you had to draw was also closely related to the way you used the heating mechanism. With the Firefly 2 this dependency is removed…because there really is only one simple and reliable way to use the heating mechanism:
Choose 1 of the 5 heat settings with the app (more on that later), just keep your fingers on the heating-sensors on the side of your unit, until the green led on top of your unit stops blinking. When it stops blinking you just draw at a consistent pace for at least 10 seconds.
Now with regards to stirring:
It’s still useful to stir your bowl every couple of draws…but even without stirring you will get close to full extraction…as long as you fill your bowl up (either with herb or the liquid pad).
What’s the bottom line?
There’s still a learning curve but it has drastically improved over the original FF.
This is where the Firefly 2 kind of sucks…
It definitely does have quite a bit of draw resistance. You will have to draw quite hard and because the vapor is so cool even on the higher temperature settings…
Sometimes you will be sucking for 10+ seconds without actually physically feeling a lot of vapor.
It gets better:
Even though you’re not feeling the vapor, you WILL get medicated from it.
The Firefly app
Firefly Vapor decided to develop an app that connects your phone to the FF2 via Bluetooth.
An app sounds really fancy…but not necessarily when you NEED it to have your vaporizer be fully functional.
They made it so that you will need the app just to change the temperature settings. I find this annoying and feel like they should’ve included this on the vaporizer itself.
You can also check the battery status…but this is bugged (it’s always full in my app). Plus you can change the way your unit heats up (both sensors, left sensor only, right sensor only).
The good thing with apps is they can keep being developed and improved…and Firefly Vapor already stated they intend to do so ;-).
Maintenance / cleaning downtime
It’s super fast and super easy.
All you have to do is brush out your bowl after all of your herb is vaped (I would say after your session here…but you can easily leave your herb in the bowl after a couple of draws if it’s not finished yet and continue vaping at a later point) and clean the bowl and the vapor path with some ISO alcohol wipes.
I would also advice to periodically clean the mouthpiece, especially the screen that’s in it (every 10 bowls is a good benchmark).
AND THAT’S IT…no deep cleaning needed with this beauty, as long as you maintain your unit the way described above.
Temperature Control (8)
The Firefly 2 has decent temperature control:
An interval based temperature-control system which will suffice for anyone but the most extreme temp control-nerds.
With 5 temperature settings for dry herb and one for concentrates, you probably won’t have a hard time finding a setting that suits your needs:
|FF2 Temperature Setting||Temperature in Fahrenheit & Celsius|
|1. LOW||340°F / 171°C|
|2. MEDIUM LOW||360°F / 182°C|
|3. MEDIUM||380°F / 193°C|
|4. MEDIUM HIGH||400°F / 204°C|
|5. HIGH||420°F / 215°C|
|CONCENTRATES||500°F / 260°C|
Keep in mind these temperature settings are only controllable with the Firefly Android and iOS app.
Here’s the deal with these temperature settings:
You won’t have full control over your temperature…thus you also won’t have absolute full control over your high (read here about how temperatures affect the medical effects of your vapor).
But you will have a good enough control to tailor your high pretty well to your specific needs.
And if you’re efficiency-obsessive…five (5) temperature settings are enough to start at the lower ranges then work your way up. You can read here why starting at the lower temperature ranges then working your way up is the most efficient way to vape your herb.
The heat-up time is where the FF2 truly shines…
10 seconds…is all it needs to produce delicious vapor. This is really quite insane because it’s a full convection vaporizer.
What this means for you is the following:
Getting a quick couple of hits in is EXTREMELY easy with the FF2…and they will be of EXTREMELY high quality.
THIS is on-demand vaporization at its finest.
Reputation and Reliability (8)
Firefly Vapor is one of the youngest vaporizer manufacturer’s around. The inception of their first vaporizer, the Firefly, dates only back to 2013. In that short period from then until now they build up a mixed reputation…
For starters…they did design a revolutionary vaporizer which basically was any connoisseurs dream.
Here’s what I mean:
Extremely tasty, cool and potent vapor blessing your taste buds and lungs in just 10 seconds…without wasting any herb.
Designing a vaporizer with these qualities…you can’t help but build a great reputation in the vaporizer world.
But there were issues as well:
Mainly faulty and unreliable battery performance.
Their customer service was decent though and they usually were prepared to replace any faulty battery. Also there were heating issues in the sense that some units had an unreliable heating mechanism.
The warranty covered all of these issues…but it cannot be denied that the original Firefly was not a very reliable vaporizer.
It seems Firefly Vapor really took these complaints to heart when designing the FF2:
It has been a short time since the FF2 came out (April 2016 for the public). I’ve had mine for 5 months now. I haven’t encountered any problems yet…the battery life is still the same. Lurking on fuckcombustion.com you will find a few users with battery issues and problems with the lid not fully hermetically sealing their unit…resulting in wispy vapor production.
Here’s what you have to understand:
With the production of any vaporizer batch, there are bound to be a small percentage of faulty units…unfortunately this is simply the nature of manufacturing. The percentage of faulty units coming with the FF2 seem to be nothing out of the ordinary up until now.
So what if you happen to get a faulty unit?
Captain obvious says: even though it’s annoying…you send it back and wait for a new one…
…if it happens to fall within the two (2) years of the warranty.
Yes…there’s only a 2 year warranty, which is quite short compared to the industry average. So that’s one thing that could be better!
Although it’s still early…the Firefly 2 is my new personal baby. I am flavor-Nazi and the flavor it produces, simply is beyond this world..
In terms of portability (size, discreetness, stealth-factor, battery-life) it has greatly improved over the original Firefly and can now qualify as a true pocket-vape.
Also it medicates really well.
But it’s potency is definitely good enough for me.
If you want to save money…
The Firefly 2 is your best mate. It actually is the most efficient portable vaporizer (butane vapes not included) that I’ve EVER tried.
There’s a slight learning curve with the FF2 and you have to stir every couple of draws to really get the most out of it, but it really improved hard over the original FF.
It does have quite a lot of draw resistance (borderline annoying). But its cleaning downtime is literally 1-2 minutes and you’ll never need to do a deep cleaning…really adding to its ease of use.
I’ll be honest with you:
The flavor, safety that an all glass vapor path provides and quick hits that an on-demand vaporizer like the FF2 provides, haven’t made me look back to my other portable vapes in a while (although lately I’ve been using my MIGHTY again, it’s just such a beast and works much better with hash).
But here’s the kicker:
I don’t really vape sessions often, I don’t need big hits and I don’t mind the draw-resistance (it’s on the border though!)…
If this doesn’t sound like you I would check out the MIGHTY (not portable but very reliable) or CRAFTY (more portable, but has reliability issues). These vaporizers are extremely powerful and extremely free-flowing (no draw-resistance) and you won’t give up much flavor and smoothness of vapor.
The Firefly 2 really is a connoisseur’s vape: modest, extremely well tasting hits available on-demand. It won’t impress any hardcore combusters!

Firefly 2 Tips and Tricks
How to grind your herb:
- Use a coarse grind. A finger grind is perfect. With a fine grind you will clog the vapor path and especially the small holes in the mouthpiece. Or you will be eating your herb.
How to pack your bowl:
- If you fill the bowl less than 50%, use the liquid pad to compress your herb;
- At least cover the surface area of your bowl to get satisfying hits (for me this is with 0.05 grams).
How to draw:
- Draw for AT LEAST 10 seconds;
- Take large and deep breaths. Really breathe into your lungs and make sure to do it with power.
Stir your bowl:
- Stir up your bowl every 2-3 draws.
How to get bigger clouds:
- If you really want bigger clouds…you can remove the screen in the mouthpiece. If you happen to get herb particles in your mouth this way, use the concentrate pad on top of your bowl (make sure the bowl is only half full though).
How to get medicated with only 0.05 grams:
- Use a finer grind than usual (finer than finger-grind, but not super-fine);
- Cover your bowl with your herb;
- Put the concentrate pad or any other screen that fits in the bowl, on top of your herb;
- Continue as usual.
