If you are in the market for a new, portable vaporizer you may want to try the Firefly 2. It is the newer version of the original, Firefly, which is manufactured by Firefly Vapor, a San Francisco company. Many people who have used Firefly will tell you that they love how fast it heats up. The Firefly 2 is even better – in 3 – 5 seconds you can have a puff. While the original was pretty easy to maintain, this one is even easier. In fact, it is the lowest maintenance portable unit that I have ever owned. The original also received complaints about battery life and portability, issues that have all been taken care of in the Firefly 2.

This review of the Firefly 2 will look at its features, improvements on the original unit, tips on how best to use and to make sure that it is an unbiased review we will look at what’s to love and not to love.

Let us start by clarifying who this unit is for. If you are looking for a smooth vaping experience with premium quality vapor then this is definitely the unit for you. Because it heats up so fast it is ideal for those who are looking to vape on the go, and also for those who like stop-and-go vaping while making maximum use of herbs. It sells for $329 and each unit has a 2-year warranty. It is best to buy from TheFirefly or Vapeworld.

Size, Portability, and Discreetness

This unit is only 2/3rds the size of the original and is about half as light. It can easily compare with the Crafty and Air brands of vaporizers. While it is smaller and lighter it is still less portable than many other brands but since it heats up fast and produces little or no smell it is the perfect device for those who want to vape in secret. While it may be visible if put in a pocket, you can easily carry it around in a bag and no one around you will be any wiser.


When it comes to accessories this vaporizer is pretty unique because it comes with 2 additional batteries – not many have even one additional one. You also get a cleaning kit (two plastics swords, a brush, and isopropyl alcohol wipes). You will also get a USB charging dock and for those who love concentrates there are concentrate pads.

Heater and Vapor Path

This unit uses a 50-watt heater under a borosilicate bowl. For herbs, there are 5 different temperature settings and there is one for concentrates. It can go as high as 400F or 204C in just 3 seconds and 420F in 5 seconds. For concentrates, temperatures can go as high as 500F. The bowl doesn’t transfer much heat and you can touch it for up to 10 seconds with no negative effects at all.

The bowl is designed this way for a reason – all the heat is used to vaporize the herbs. When you switch it on all the heat is directed at the herb with no heat being transferred to the glass bowl. You can have several sessions with one bowl without losing herb flavor. The bottom of the bowl is dotted with a 55-hole pattern to allow for better airflow (an improvement on the original design). It has a slight glow when you first heat it up – a pretty cool feature, but if you don’t want the glow to give you away you can cover it with the palm of your hand.

Apple and Android Application

The Firefly is controlled through an app that is both for Apple and android. It connects through Bluetooth and it can be used to control temperature settings, check battery life and change other settings on the unit. For herb you can choose between 340, 360, 380, 400, 420 F and but for concentrates you only get one setting, 500F.

Cleaning and Maintenance

As I mentioned at the beginning, this is one of the easiest portable convection vaporizers to clean and maintain. In fact, it doesn’t need to be cleaned very often – you can go for a long time without cleaning it and its performance will not be affected. That said, there will be some buildup on the window but this will not affect your vaping experience. The process is very simple – all you need is an isopropyl alcohol wipe – you get a couple of these with the original kit. Clean the vapor path, the body and the lid and your unit is ready for use once more. If you run out of isopropyl alcohol wipes you can use paper towels doused in isopropyl alcohol.

In case you are wondering how long you can go between cleanings, I have been able to use it for 26 bowls before the buildup on the glass got in the way of the seal and also the overall performance of the unit. I scraped it off and was able to seal it properly and use it again with no loss of performance. This alone makes it ideal for people who enjoy vaping but don’t have a lot of time for cleaning out equipment.


The main problem with the original Firefly was its battery life – the battery had one of the shortest spans in the market, and there were manufacturing issues that caused batteries to last only a short time. The newer model has taken care of these problems. I found that there was more than a 100% improvement, which allows for longer vaping sessions with maximum draws at high temperatures. You can go a full six bowls after each fresh charge w2ith each bowl giving you between 6 and 8 draws for between 30 and 45 seconds. This is for herbs, but with concentrates, I have realized that you get a shorter battery life which is not unusual because they burn at a higher temperature. The additional pair of batteries makes things even better especially for those who are away from home for long periods. Better yet, the battery only takes between 45 and 50 minutes to charge and they get to 80% within the first 20 minutes. You can use the charger from your original Firefly.


I have been using this vaporizer for a month now and I can tell you that so far I love the experience. Each vaping session produces smooth, flavorful vapors. It doesn’t require much in the way of technique – even a beginner will be able to vape without any trouble. The experience is great whether you are using herb or concentrate.

The only complaint I have is that it has to be stirred to make the best of your herbs. I found a way around that – I don’t pack it so tight so that I can tap it against my hand.

As mentioned earlier, it is best to buy your Firefly 2 from FireflyVapor or VapeWorld – compare both because from time to time they have discounts and gifts.

Overall, I highly recommend this vaporizer whether you are a beginner or a seasoned vaper.
