Firewood 4 Vaporizer Review – Fire in the hole!


The Firewood line of vaporizers is probably the least known of all dry herb options. The reason? These are all handmade from wood by one guy in his basement! That’s pretty remarkable in its own right, and you have to admit, they look slick. The first Firewoods had their fair share of both fans and haters, but today we’ll be looking at the newest option, the Firewood 4. This isn’t the easiest to use. You could even call it difficult. But if you love vaporizers, you need to check it out.

Review: Firewood 4

How it Works

If you have tried any of the original Firewoods and are expecting something similar out of the Firewood 4, you’re wrong. Other than the attractive wood construction, this is a substantially improved vaporizer from earlier models.

To turn the unit on, you click the button (also wood) on the bottom of the unit and hold it for a few seconds. There are no indicator lights, but there is haptic feedback (vibration) that will tell you everything you need to know. Right away, you will feel vibrations to let you know how much battery life is left.

Once on, you choose a heat level by clicking the button again. The amount of clicks depends on the heat level you want to achieve (1 click = level 1, 2 clicks = level 2, etc…).

Here’s where the coolest feature of the vaporizer comes into play: it only heats while you are drawing.

Older versions of the Firewood were known for hot mouthpieces, so this one has a new cooling chamber that sits on top of the glass herb chamber. This can be swiveled around, and a glass ‘straw’ pulls out from it. You take your draws from this.

Temperature flexibility is good, albeit complicated. Another thing the Firewood line has always been known for is being more manual than automatic.

While the days of simply holding a button and guessing how hot the temperature was are gone, the Firewood 4 still has some quirks that take some practicing. Setting temperature is one of them.

To start, you get a base set of temperature levels to choose between, but they can all be customized. This is tricky for some because there is no display to help you.

You are essentially programming your device with a series of clicks. We won’t get into it here, because you’re better off just reading the instructions on the Firewood website.

On top of changing the temperature levels, there is also party mode. Party mode is a setting that keeps the temperature constant for longer after a draw is completed. The default is one second. You can change it to up to 16 seconds. This makes it easier for groups to pass the unit around, especially when some users don’t know how to use the device.

Vapor Quality

Vapor quality can be good, but it can also be bad.

Getting the most out of the Firewood 4 takes practice, which is something a lot of people aren’t interested in when choosing a vaporizer. If you just grab it and keep taking draws, its very easy to get harsh vapor, especially towards the end of a session.

At the same time, this can produce very good vapor and even give off some unique flavors that are the results of the wood design rather than the usual metal or plastic.

Manufacturing Quality

This is a handmade wood device. As far as vaporizers go, it would be hard to argue that any have more thought or effort poured into their creation.

We’ve heard the Firewood 4 be described as functional art on more than one occasion, and that seems like a fitting description.

That doesn’t meant it’s easy or convenient to use, but it certainly is well made and it’s also the most visually appealing vaporizer we’ve ever seen.

Firewood 4 BatteryBattery Life

A battery doesn’t come standard with the Firewood 4, but you can add a LG HG2 18650 for just $10 and a charger for $15 more.

This may seem odd to some of you, but it’s ultimately the result of the creator trying to keep costs as low as possible.

He’s making these handmade by himself and trying to compete with mass produced units in China. A lot of people already have 18650s, so he’s giving you the option of not buying one so it’s cheaper.

The fact that you can remove the battery is nice because it means you can get extra. This gives you an unlimited upside for battery life, because you can always have one ready to swap in if one dies.

The portability is good. If you had the Firewood 3, you’ll notice that the 4 is actually significantly smaller.

The wood construction also makes this a bit more durable than many units, and it’s thin enough that you can carry it in a pocket or Zeus Armor Case.

Ease of Use

This isn’t easy to use. Sure, you can turn it on and get vapor easily, but that’s not how this was intended to be used.

To get the most out of this, you’ll have to spend a decent amount of time reading the instructions and learning how to program the device to your own preferences. If you want something easy, check out a unit like the Utillian 720, which is much easier to operate right out of the box.

I can see this being a fairly discreet device. The wood exterior will help it blend into it’s surrounding pretty easily and it’s small enough to quickly conceal.

There is a caveat though. It also looks like a dugout. Dugouts haven’t been a popular way to smoke for quite some time, but many people will still see this and think of them.

The Firewood 4 is a very cool vaporizer, but it isn’t for everyone. If you don’t have a vaporizer yet, we’d even go as far as saying that you should definitely not get this.


This is a vaporizer for connoisseurs. You know who you are. If you’re the type of person who loves vaporizers and has an entire shelf dedicated to them, you need to get this. It works great when you take the time to learn it’s nuances, and it’s also one of the most unique vapes on the market. The fact that it’s wood and handmade seals the deal.

If you are looking for your first vape, then go with something more beginner friendly. The Utillian 720 and Arizer Solo 2 are both good options.

Compatible with ZEUS Iceborn
This vaporizer is compatible with the ZEUS Iceborn, a revolutionary new vapor cooling system engineered by Canadian vape manufacturer ZEUSArsenal. The Iceborn is designed to produce cooler draws and bigger clouds when connected to your vaporizer. The vapour produced is ultra smooth and crisp and because of ice cooling, instead of water filtration, there is no loss of efficiency. The ZEUS Iceborn adds an additional 2 points to the vapor quality score of this vaporizer and is a highly recommended vaporizer accessory.
