Best Backpack Leaf Blowers
To help you select the right product for your circumstance, I have compiled a buying guide below, so that you understand the options available to you. Have a read-through so you can figure out what’s the most important characteristic to you… run time, noise output, or overall blower power.
Gas vs Electric Backpack Leaf Blower
Backpack leaf blowers fall into two power types, gas and electric. Both have their pros and cons, so let’s begin by breaking down the differences between gas vs electric leaf blowers.
Electric Backpack Leaf Blowers
An electric backpack blower is typically cordless and powered by lithium-ion battery cells, more on batteries later.
Because electric blowers feature a relatively simple motor technology, they are lighter, eco-friendly, quiet to run, and require minimal maintenance and servicing.
Being free from a power cord offers a whole perspective on mobility. Once mounted on your back there is no power line tethering the user to the main power socket meaning you can wander freely between trees and other obstacles gathering leaves, unlike a corded electric leaf blower.
So, what’s the catch…? Well, lithium-ion batteries have a relatively short runtime, typically ranging between 20 – 50 minutes. However, there’s nothing stopping you from getting multiple batteries and simply switching them over to keep you blowing for hours.
60V vs. 80V Leaf Blowers
Most electric backpack leaf blowers run on Li-Ion batteries, with a voltage power output of between 60V and 80V. Generally, the higher the Voltage (V) the more power the machine can generate by way of blowing power or the amount of air moved in Cubic Feet per Minute (CFM).
Here’s a brief comparison between the practical uses and differences between 60V and 80V machines
The higher wattage an electric backpack blower has, the higher its maximum airspeed, and conversely, the better its performance. On that basis an 80V electric backpack leaf blower has a higher average wattage, therefore they are more powerful than their 60V counterparts.
Size and Weight
An electric backpack leaf blower with an 80V battery will offer better performance, but it’s typically bulkier and heavier than 60V-powered blowers.
Battery Run and Charging Times
Although an 80V powered electric leaf blower consumes more energy, it often has a higher Amp-Hr battery offering longer runtimes than a 60V equivalent. However, conversely when it comes to charging time the 60V battery will generally charge in a shorter time than batteries for 80V machines.
Battery Power (Ah)
Voltage is not the only factor concerning an electric blower’s battery. The run time of the battery is also essential to give your leaf blower enough stamina to get the job done. Lithium-ion battery power is measured in amp-hours or Ah.
As the name suggests, Amps hours tell you how many amps a power device uses in one hour. This means how much current the charged battery will discharge at a steady rate.
For example, a 100Ah 60V battery would deliver 100 amps of current to a 60V device per hour, or it could provide 50 amps of current to a 60V device in two hours.
What does all this mean practically? The bigger the Ah, the more energy the battery can store, and the longer you can power a device. If you are concerned with how long your electric leaf blower will last in one sitting, you need to pay attention to the Ah of the battery.
Gas Backpack Leaf Blower
As the name implies, a gas backpack blower runs on gasoline and will be fitting with either a 2-cycle (2-stroke) or a 4-cycle engine (4-stroke). A gas-powered leaf blower is typically more powerful than any other technology, making it ideal for demanding tasks and commercial use.
Furthermore, given it runs on gasoline, a gas backpack blower doesn’t require battery recharging and offers perfect maneuverability.
Gas backpack leaf blowers also deliver maximum runtimes. The downside is that gas backpack blowers are usually louder, heavier, and discharge smelly emissions. Plus, you’ll also need to change the oil and perform engine tune-ups and maintenance.
What to Look for in a Backpack Leaf Blower?
Whether you chose a backpack leaf blower that is powered by gasoline or a lithium-ion battery is just the first decision you need to make. I recommend you also pay close attention to the many other features of these machines. As well as reviewing their comfort features, and controls to make sure you are choosing the best backpack leaf blower for your circumstances. Here’s my guide to help you understand each of the main features that you need to look out for.
- Leaf Blower CFM
- Leaf Blower MPH
- Speed Settings
- Harness & Padding
- Trigger Controls
It’s worth spending a few minutes reading through my guide to each of these features to keep your buying decision informed.
Leaf Blower CFM
When measuring the volume of airflow displaced by a leaf blower the term CFM is used, as an abbreviation of Cubic Feet per Minute. Simply meaning how many cubic feet of air the leaf blower expels each minute.
So why is CFM important? Well, it’s a general number used to compare the power of the leaf blowers. It does not necessarily mean a blower with a CFM of 300 is better at moving leaves than a blower with a CFM of 250. The diameter of the pipe that the air is blowing through also has a bearing on this.
I know this may sound a bit abstract so imagine a hose pipe with a flow of water. If you reduce the diameter of the end of the hosepipe by pressing it between your thumb and finger, you create a fast, strong water jet. Well, the same happens with air.
Think of two leaf blowers each having a CFM of 300, but blower one has an air nozzle that is narrower in diameter than the other. The unit with the narrower diameter nozzle will generate a faster (mph) jet of air to displace the leaves.
What Is a Good CFM for a Leaf Blower?
A leaf blower with a CFM rating between 200 and 400 will get the job done for a small to medium size yard with simple landscaping needs. For heavy or damp leaves in large spaces, you may be looking for a model with a CFM of over 400.
Leaf Blower MPH
Mile per hour…I am sure you will be familiar with this term, of course, it’s the speed of the airflow. The speed of the airflow combined with the CFM cubic volume per minute has a direct relationship in generating the overall volume and speed of airflow to blow leaves. In both cases the higher the maximum MPH or CFM the better.
Most leaf blowers have several speed settings to allow a level of control over the airflow. Too much air bounce of walls or static objects and cause a swirling gust of air sending leaves everywhere.
In this situation, it’s ideally to turn down the airflow and a gentler speed will give the user better control to gather leaves into neat piles.
Noise Levels dB
Whether you choose a gasoline or battery backpack leaf blower, one thing is for sure…they are not going to be quiet. Expect real-world decibel levels to range somewhere between 70-100 dB, so ear protection is recommended.
If you’re looking to cover large areas or have frequent use of your backpack leaf blower, then machine run-time will be an important statistic to look out for. Gas machines will typically give you between 30-60 minutes run time on a single tank, whilst battery models will manage between 12-20 minutes depending on the battery pack size.
Gasoline Fuel Tank
For gas-powered leaf blowers, the size of the fuel tank is a good guide to the blower’s run time. The more fuel it can carry in the tank the longer you will have on continual use. Some gas engines will demand more fuel per minute to run, but for simplicity put this aside and look for a higher fuel capacity. Aim for at least 40 fl oz or more which should see you get 40 minutes or more in run time.
Lithium-Ion Battery (Ah)
As I have mentioned previously battery run time is defined by their amperage per hour so again aim for a run time of around 30 minutes for any battery-powered models.
Backpack Leaf Blower Comfort
Ergonomics are a major factor when you consider backpack leaf blowers are heavy and put out a fair amount of noise. You want to avoid early fatigue to make sure you get that job finished.
Straps & Padding
Shop for models with a well-padded, breathable harness construction for ease of use. No different from buying a rucksack or backpack for outdoor leisure use, you need a comfortable shoulder strap and possibly a waist strap. Plus, a decent level of padding across the back to cushion the weight of the machine.
Leaf Blower Handles & Trigger Controls
The more powerful the backpack leaf blower, the more control you need over the air pipe. So, a solid trigger handle is important with easy to reach controls that are simple to use. To be fair they are usually designed well, and the buttons or levers are easily accessible whilst the machine is in operation.
They make your leaf blower more functional since you can switch between different attachments to make your unit better suited for a specific function
Usability: Some models feature a stop switch to automatically reset your blower to ON mode, while others feature an air purge to expel air and make start-up easier. Look for a unit with such features for easier use
Best Backpack Leaf Blower Reviews

The engine delivers maximum power at low RPM, making the model even more eco-friendly and easier to handle. On top of that, it has variable speed and cruise control options to choose and maintain favorable blowing speed during clean-up.
What I loved most about the Husqvarna 360BT is its high blowing capacity. It has a total maximum power speed of up to 8100rpm, which when combined with its 74.4fl.oz fuel tank means you get to effectively blow away stuck leaves and debris for over an hour without having to refuel.
Like the Husqvarna 150BT, the 360BT also spots an orange color and has an adjustable, breathable, load-reducing harness for a fatigue-free yard cleanup experience. It, however, stands out from other Husqvarna models thanks to its offset handle design. The handle adds to the comfortable user experience by keeping the nozzle steady at all times.
The blowing tube has an adjustable length, allowing you to comfortably reach and clean those hard-to-reach places in your landscape at ease. All the controls are intuitively placed together on a tube-mounted throttle.
It has an air purge to dispel air from the carburetor and make startup seamless. On the downside, the Husqvarna 360BT has a noise rating of 97 decibels, meaning it is pretty noisy.

The Echo PB-58.2CC is equipped with a metal ring to protect the hose end from damage which is a great touch and again reconfirms this product is built to last and cope with the most heavy-handed users.
The backpack harness has a neat design on the vents to keep your back breathing and prevent sweating while efficiently balancing backpack weight to prevent user fatigue.
The backrest and shoulder straps are also well padded to provide the utmost comfort during landscaping.
On the back is a translucent, 62fl. oz fuel tank offering a clear view of the tank fuel level, it also has a nice wide refile cap to avoid spillage. I managed 60 minutes of continuous use on a single tank of fuel.
Compared to some other models I reviewed on the list, the Echo PB-58.2CC is not as noisy and with a noise pressure rating of 70 decibels, which is not exactly quiet but again for a gas machine that’s pretty good.
The Echo PB-58.2CC backpack leaf blower ships with a 2-stroke engine and delivers a huge 510CFM at 215MPH for efficient landscaping all year round.
All-round a great backpack leaf blower and a close second to the Husqvarna. The Husqvarna comes with a proven pedigree and generates a better airspeed but also a lighter price tag, otherwise, it’s difficult to split them.
Check the Echo PB-580T latest price here
- Power: 5.0Ah Electric Battery
- Engine: 60V Brushless Motor
- Air Flow: 530CFM
- Air Speed: 140MPH
- Sound Level: 80dB
- Weight: 14lb (with battery)
- Run Time mins: 27 on High, 13 on Low
- Exceptionally lightweight leaf blower
- Good air volume, fair power

- Much louder than the Greenworks 80V option on the list
Weighing only 14lbs with a battery, the Powerworks 60V Backpack blower is one of the lightest models in the market, which will appeal to many domestic users.
The speed trigger, cruise control, and turbo buttons are all conveniently placed on your left hand so that your right is free to hold other gardening tools.
Like most models on this list, the Powerworks 60V backpack leaf blower also features an adjustable, ergonomic harness to evenly distribute the user’s weight, conversely preventing fatigue, mainly if you use it for extended periods.
You also don’t have to stress about damaging your blower since the Powerworks 60V battery features a unique metal scrape to protect your blower’s tube from damaging dirt and debris.
With its compact size, the Powerworks 60V backpack leaf blower doesn’t generate the same level of power as some of the other machines, so for me, it falls somewhere on a no-mans-land, with the Greenworks 80V 580CFM blower being the same weight, having more power and being much quieter.
Capable of handling both light to medium tasks, with a variable speed setting, plus cruise control allow you to control your landscaping tasks since you get to choose and maintain a desirable speed.
It ships with a 5Ah battery or 2.5 Ah option. I must stress to go ahead with the 5.0Ah version to get anything like a sensible usage time from this blower. 27 mins are possible with the 5.0Ah lithium-ion cell.
On the upside, the battery charges fast and is compatible with other Powerworks and Snapper 60V tools.
Overall a good machine, but if you need power there are much better gas or electric models available. If you need silence go for the Greenworks 80V blower.

Leaf Blower 2 Cycle Vs 4 Cycle Engines
For the nerds amongst us, you may be wondering what the difference is between a 2 Cycle engine and a 4 Cycle engine and what practical benefits you will find with your leaf blower performance and maintenance. So here’s a quick guide to the differences between 2 cycle and 4 cycle engine technology.
2-Cycle Backpack Leaf Blower – Engine Overview
For a backpack leaf blower engine to run efficiently, combustion needs to happen. In a 2-cycle backpack leaf blower, the combustion cycle is usually complete in two piston strokes-one up and another down the cylinder.
During the second stroke, the exhaust releases, and a mixture of fresh fuel gets into the cylinder, conversely producing power once with every two strokes. A 2-cycle backpack leaf blower’s engine runs at a higher RPM and can produce more power without increasing displacement thanks to the short cycle.
Thanks to this, some of the best 2-cycle backpack leaf blowers have an even higher power output than some 4-stroke backpack leaf blowers.
A 2-cycle leaf blower engine has three primary moving parts-the piston, crankshaft, and connecting rods. Thanks to this simple engine design, 2-cycle backpack leaf blowers are often lighter and have simpler maintenance requirements. They also produce fewer vibrations and are easier to store.
On the downside, a leaf blower with a 2-cycle engine lacks a separate oil chamber meaning you have to premix oil and gasoline first. 2-cycle backpack leaf blowers are also less fuel-efficient and are significantly louder.
Also, combustion happens in two-cycle, meaning backpack leaf blowers with a 2-cycle engine aren’t as eco-friendly since they release burnt oil into the environment.
4-Cycle Backpack Leaf Blower – Engine Overview
With a 4-cycle backpack leaf blower, the engine makes four piston strokes to complete one combustion cycle. The cycle usually starts with an intake stroke, during which air and fuel enter the combustion chamber.
The intake valve opens when the piston moves down, creating a vacuum to suck up air and fuel mixture into the combustion cylinder. The piston then moves up again, compressing the air-fuel mixture.
Once the piston is at the top again, ignition occurs, causing it to move downward, but this time, only the exhaust valve opens to push the burned air-fuel mixture out. It then closes, and the cycle starts all over again.
Thanks to the engine’s mechanism, 4-cycle leaf blowers produce more power and run more quietly. A 4-cycle engine also features a pump to keep oil properly circulating when the piston moves. As a result, you don’t need to mix oil and fuel and also get to cut on the blower’s running costs since oil is recycled indefinitely and they’re more fuel-efficient.
Fuel is also burned more effectively during the combustion cycle, making 4-cycle engines more eco-friendly. A 4-stroke backpack leaf blower is also more durable. However, you may find it heavier than the 2-cycle engine, and because it has more parts, a 4-cyle engine needs more maintenance.
How to Start a Backpack Blower
Starting a backpack leaf blower is as easy as handling the unit itself during use. Here’s what you need to do:
- Slide the stop switch (if it has one) to the “ON” position
- Hold the blower firmly with your left or right hand and pull the starter knob firmly until the engine fires
- Allow it to warm up, especially if it’s cold, place it on your back, hold the throttle with your active hand and start blowing
Verdict: Best Backpack Leaf Blower
There you go; a list of the best backpack leaf blowers based on first-hand testing. Since options vary, prioritize the size of your yard and everyday landscaping tasks you handle to select a model ideal for your needs.
