The Firefly 2 is the second iteration of the on-demand, dynamic convection, portable vaporizer from Firefly Vapor. Firefly was founded in San Francisco back in 2012. The heat-up times on the original Firefly was pretty much game-changing and they have made the Firefly 2 heat up even quicker. You can start a session with the FF2 in as little as 3-5 seconds.
Update: The Firefly 2 is no longer being sold, and the current model is the Firefly 2+ (Plus). Check out my Firefly 2+ (Plus) Review for a complete breakdown.
The original Firefly was also fairly low maintenance, but the new unit has some of the lowest upkeep of any of the portables I own at this point.
I am also glad to report that the biggest complaints in my original Firefly review, like the battery life, overall size & weight, have all been addressed. If you’re looking for the cleanest-tasting portable convection vaporizer, look no further than the Firefly 2.
Like the original FF, this unit is perfect for someone who is looking for a premium taste with a smooth, cool temp.
The Firefly 2 has nearly instant on-demand heat up, which works great for people who like a really quick session or prefer to split bowls into multiple different sessions.
The Firefly 2 is no longer for sale, but they have released the Firefly 2+ (Plus), and it retails for $249. I highly recommend checking out my review. They have made some great improvements. Read on below for my full original Firefly 2 review.
Portability and Discreetness
The Firefly 2 is 33% smaller and 55% lighter than the original Firefly. The unit is now very similar in size and weight to the Crafty and the Air vaporizers thanks to them switching from a stainless steel body to a magnesium alloy body.
While the FF2 is not the most discreet unit at first glance, its near-instant heat up for quick sessions and minimal smell compared to the average portable vaporizer makes it pretty easy to use on the down-low.
Accessories
The Firefly comes with two easily swappable batteries which are really cool since very few vapes come with more than a single battery. The unit also comes with a cleaning kit that includes two plastic toothpick/sword tools, and a great multi-sided brush, and a couple of isopropyl alcohol wipes. The unit also comes with a USB charging dock, and concentrate pads
Heater and Vapor Path
The Firefly 2 uses a 50-watt heater and a borosilicate glass bowl. The Firefly 2 offers six different heat settings. Five settings for dry herbs and one setting for concentrates. The FF2 will reach 400F (204C) in three seconds and 420F (215C) in five seconds.
The glass bowl transfers very little heat. I can literally place my finger in the chamber (touching the glass side and the metal bottom), set it to concentrate temp (500F or 260C) and hold the trigger down for nearly 10 seconds before my finger starts to get warm. This is why this unit is so efficient at breaking single bowls into multiple sessions because it only heats the herbs while you are drawing.
The Firefly2 uses 55 hole pattern in the bottom of the bowl and larger air intakes compared to the original unit for increased airflow. However, like the original, the new Firefly 2 faintly glows when it first ramps up to temp which looks pretty cool. You can also cover the glow with your hand pretty easily if your were trying to use it discreetly in the dark.
iOS and Android Application
The Firefly 2 uses an application available for both iOS and Android which connects to the Firefly 2 via Bluetooth. With the app, you can change the temperatures, check battery life, and change a couple of different settings on the unit.
The Firefly 2 has 5 temperature settings for dry herb 340, 360, 380, 400, 420 Fahrenheit (171, 182, 193, 204, 215 Celcius) and one setting for concentrates 500F or 260C.
Cleaning and Maintenance
The Firefly 2 is actually one of the easiest vapes I have to clean. It can go long intervals in-between cleanings without any performance loss but will get some buildup on the window. There is no screen in the bowl to replace or clean. You basically just take a paper towel with some ISO propyl alcohol on it and wipe out the bowl.
Next, wipe down the vapor path on both the body and the lid and boom, you are done. Altogether I am usually done cleaning in under a minute.
I was able to vape 26 bowls before I noticed any performance degradation. The buildup on the lid caused the unit to not fully seal but a quick wipe down had it good as new.
Firefly 2 Battery Specs
The battery life on the original Firefly was definitely the biggest drawback. Not only did the FF1 have the shortest battery life per charge, but it also had manufacturing quality problems which caused a percentage of the batteries to degrade faster than they should have. With the new Firefly 2, they have drastically improved heating efficiency and Firefly Vapor says they have improved battery life by over 100%. In my testing, I was trying to take every draw to the max length (30 seconds), and I tested at 420f to keep a consistent setup.
I have been getting 6 bowls per charge for dry herb, and each bowl is usually getting 6-8 draws for a total of about 35-45 ~25-30 second draws. With concentrates the battery life is reduced a bit.
Overall, I get a good amount of bowls per charge, and the unit comes with 2 easily swappable batteries so I’m quite happy with the battery situation. The icing on the cake is that the batteries charge in roughly 45-50 minutes and they hit 80% charge in the first 20 minutes. They can also be charged in the original Firefly external charger.
Review Summary
Over the last month of testing, I have really grown to love this vaporizer. My favorite parts about the unit are the amazing flavor and cool vapor. It’s really enjoyable to use and efficient with my herbs.
It does require a bit of practice and technique to get the best results, but on the plus side, it requires almost no cleaning or maintenance.
For people who like to use concentrates as well as dry herbs, this has become my favorite unit for concentrates. The 500F concentrate temp not only gives amazing flavor but very potent draws. My biggest complaint is that it needs to be stirred or mixed up for the absolute best results and most even AVB. If you don’t pack it too tight, you can generally tap the bowl against your hand to mix/stir it up.
The Firefly 2 is no longer for sale, but they have released the new Firefly 2 Plus. The new 2 Plus vaporizer is what the Firefly 2 should have been. Much easier to use and get consistent results, improved battery life, and less draw resistance. I highly recommend checking out the review.
