The Firefly 2 is the second iteration of the on demand dynamic convection portable vaporizer from Firefly Vapor. A company founded in San Francisco back in 2012. While I love how the original unit heated up almost instantly, they have made the FF2 heat up even quicker, now in as little as 3-5 seconds. The original unit was 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 my biggest complaints about the original unit like the battery life and the size & weight have all been addressed.
This Firefly 2 vaporizer review will give a rundown of the features, discuss some of the changes from the original unit, go over how to use the unit including some of the tips, and then talk about the pros and cons of the unit.
Like the original unit, this unit is perfect for someone who is looking for premium vapor quality with amazing and smooth flavor. The FF2 has nearly instant on demand heat up so the unit works great for people who like a really quick session and for people that like to split a bowl into multiple different sessions efficiently without wasting their herbs.
Size, 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 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 is 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 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 has 6 different heat settings, 5 settings for dry herbs, and one setting for concentrates. The FF2 will reach 400F (204C) in 3 seconds and 420F (215C) in 5 seconds. Since the glass bowl transfers minimal heat, I can place my finger in the bowl (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 hot, and only on the bottom.
This is why this unit is so efficient at breaking a single bowl into multiple sessions, it only heats the herbs while you are hitting it. The Firefly2 has a 55 hole pattern in the bottom of the bowl and larger air intakes compared to the original unit for increased airflow. Like the original unit the Firefly 2 faintly glows when it first ramps up to temp which looks pretty cool, when you wan’t to use it discreetly in the dark its quite easy to cover the glow with your hand.
Apple and Android Application – The Firefly 2 uses an application available for both Apple and Android to connect to the Firefly 2 via Bluetooth. You can change the temperatures, check battery life, and change 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. Firefly Vapor has said having the application will allow them to add new features in the future.
Cleaning and Maintenance – The Firefly 2 is actually one of the easiest vapes I have to clean, and it can go long intervals in-between cleanings without any performance loss, although you will get some buildup on the window. There is no screen in the bowl to replace or clean, you basically just take an isopropyl alcohol wipe or a paper towel with some isopropyl alcohol on it and wipe out the bowl, then wipe down the vapor path on both the body and the lid and you are done.
Altogether I am usually done cleaning in under a minute. When I was testing how long the unit could go in-between any cleaning before I noticed any performance degradation I got to 26 bowls before the buildup on the lid caused the unit to not fully seal, I was able to use my fingernail to scrape around the bowl and get it to seal after just a few seconds and then it was working perfect again.
Battery – 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 the 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, they hit 80% charge in the first 20 minutes, and they can be charged in the original Firefly external charger.
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, and that it’s just really enjoyable to use and efficient with my herbs. It requires minimal technique/practice to get the best results and 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, which is still pretty minor is that it needs 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.
