2. Aramox battery-powered backpack sprayer 

The Aramox Battery-Powered Backpack Sprayer combines high performance spraying and battery capacity in an affordable package. 

Here is what we liked:

• The 85 pounds of pressure per square inch delivers a powerful jet stream. 
• The 8 amp-hour battery capacity is more than sufficient for longer jobs. 
• The removable nozzles provide a variety of spraying options.

One of our favorite things about this model is the price. This battery-powered backpack sprayer has the lowest price tag on our list. 

The downsides: This Aramox backpack sprayer loses a few points for battery strength. Its 12-volt battery is decent, but you’ll find much more powerful models below. 

Specifications:

• Tank Capacity: 4.2 gallons
• Power: 12 volts
• Maximum Pressure: 85 psi
• Battery Capacity: 8 Ah
• Weight: 11.28 lbs

3. HPDAVV 4 gallon battery-powered backpack sprayer

The HPDAVV 4-gallon garden sprayer has a lot going for it: steady stream of spray, above-average battery strength, and it’s affordable.

Bonus points: This machine is easy to use with its squeeze handle, locking mechanism, and different nozzles for a variety of spraying styles. We also like the ergonomic shoulder straps. 

This model loses a few points for spraying pressure and weight. While none of this backpack sprayer’s stats is bad, neither is any one of them particularly impressive.

• Power: 18 volts
• Maximum Pressure: 65 psi
• Battery Capacity: 4 Ah

• Price Range: Inexpensive

4. Cardinal 4 gallon battery-powered backpack sprayer 

The Cardinal 4-gallon battery-powered backpack sprayer is the most powerful model on our list. Capable of spraying 6,000 square feet in under 10 minutes, this model will serve you well when tackling heavy-duty jobs. 

Other things worth noting:

• The 4 amp-hour battery can spray up to 200 gallons on a single charge, so you won’t need to constantly refill. 
• The interchangeable spray nozzles let you spray a wide area or get to tough-to-reach places. 

This model loses points in a couple of places. First, at 14 pounds, it’s on the heavier side. We wouldn’t recommend this model for anyone with back problems. Also, the water pressure could be a little more powerful for the voltage. 

Specifications:

• Tank Capacity: 4 gallons
• Power: 21 volts
• Maximum Pressure: 65 psi
• Battery Capacity: 4 Ah
• Weight: 14 lbs
• Price Range: Medium

✗ Subpar water pressure

5. ENERTWIST 20V battery-powered backpack sprayer

The Enertwist 20V is the lightest battery-powered backpack sprayer on our list. Weighing in at just over 3 pounds dry, you can get your yard work done without straining your back. 

Other things we like about this sprayer: The 70 pounds per square inch hose pressure, the powerful 20 volt battery, and the large mouth opening, which makes this sprayer easy to fill. You’ll also find this model in the least expensive end of the spectrum, making it a good buy if you are on a budget. 

The downsides: Of course, with a lighter model, you have to make a few sacrifices. In this case, the tank is only 3 gallons, and the battery holds an unimpressive 2 amp hours of charge. 

Translation: This model isn’t for you if you plan on using it for long spraying sessions. That said, if you have a smaller yard and are looking for something to accommodate lighter work, consider this model a pretty good bet. 

Specifications:

• Tank Capacity: 3 gallons
• Power: 20 volts
• Maximum Pressure: 70 psi
• Battery Capacity: 2 Ah
• Weight: 3.08 lbs
• Price Range: Inexpensive

Pros:

Cons:

✗ Low tank capacity
✗ Shorter battery life

6. PetraTools 4 gallon battery-powered backpack sprayer

With the PetraTools 4 Gallon battery-powered backpack sprayer you can spray for six to eight hours on a single charge, making it ideal for spraying large areas.

Other things we like: 

• The translucent tank with gallon markings lets you know how much liquid you have left to spray.
• The sprayer tank’s wide mouth makes for easy filling.

The downsides: This battery-powered backpack sprayer is unfortunately a little on the heavy side at almost 15 pounds. Also, the 12-volt battery isn’t anything to brag to the neighbors about. 

Bottom line: This PetraTools backpack sprayer is, overall, a powerful model with a strong battery life for a medium price. 

Specifications:

• Tank Capacity: 4 gallons
• Power: 12 volts
• Maximum Pressure: 70 psi
• Battery Capacity: 8 Ah
• Weight: 14.72 lbs

7. FlowZone Typhoon 2

The FlowZone Typhoon — note that name — has the mightiest spray stream of the battery-powered backpack sprayers on our list. You’ll want this sprayer’s whopping 115 pounds per square inch of pressure if you are trying to reach treetops or need to cover a lot of area quickly. 

There are only two major drawbacks to this powerful spraying machine: 

• Cost: It’s in the top third of the sprayers we surveyed. 
• Weight: At 14 pounds, you’ll need to be in shape to lug this sprayer around your yard. 

That said, if you’re looking for raw power, and cost and weight are of little concern, this typhoon of a sprayer might be exactly what you want. 

Specifications:

• Tank Capacity: 4 gallons
• Power: 18 volts
• Maximum Pressure: 115 psi
• Battery Capacity: 5.2 Ah
• Weight: 14 lbs
• Price Range: Expensive

Pros:

✓ High pressure stream
✓ Excellent battery power and battery life

Cons:

✗ On the heavy side

8. Tomahawk Power 4.75 gallon for pest control disinfectants

The Tomahawk Power 4.75-gallon is perfect for someone who doesn’t want to recharge all the time, or someone who just enjoys spraying mosquitoes so much they lose track of time.

Here are a couple of the Tomahawk’s appealing features:

• A 4.75-gallon tank is great if you have a lot of spraying to get done. 
• Running a 12-volt battery on 5 amp hours allows for up to 11 hours of spraying on a single charge. 

The Tomahawk’s only drawbacks are its price and power. Its 12 volts is OK, but for the price, we think this backpack sprayer could be more powerful. 

Specifications:

• Tank Capacity: 4.75
• Power: 12 volts
• Maximum Pressure: 70 psi
• Battery Capacity: 5 Ah
• Weight: 9.3 lbs
• Price Range: Expensive

✗ Battery could be more impressive

9. PetraTools 3-gallon battery-powered backpack sprayer

The PetraTools 3-gallon is a great battery-powered backpack sprayer for anyone on a tight budget. 

There is a lot to like about this PetraTools sprayer:

• With a small 3-gallon tank and weighing under 10 pounds, this model will make your life easier. 
• The translucent tank has clearly marked measurements, so it’s easy to see when it’s time to fill up. 
• The variety of nozzle attachments provides a range of spray patterns. With 3.3 amp hours, the battery life is decent and sprays for about two and a half hours. 

We also love the price tag of this PetraTools battery-powered backpack sprayer.

The drawbacks: With the PetraTools 3-gallon, you are sacrificing a little power. This model only has about 65 pounds of pressure per square inch, and the battery only gives you 12 volts of operational electricity. And, with that 3-gallon tank, you can’t carry as much weed killer as with most other models. 

Bottom line: The PetraTools 3-Gallon is a good model for anyone with light spraying work to do who doesn’t want to spend or carry too much. 

Specifications:

• Tank Capacity: 3 gallons
• Power: 12 volts
• Maximum Pressure: 65 psi
• Battery Capacity: 3.3 Ah
• Weight: 9.28 lbs
• Price Range: Inexpensive

Pros:

✓ Lightweight
✓ Inexpensive

Cons:

✗ Not very powerful

10. KIMO 3 gallon backpack sprayer 

The KIMO 3-gallon 20-volt battery-powered backpack sprayer is a perfect model for someone who doesn’t want to carry a lot of weight, but still has some serious hosing to do. 

Here are some of its best features: 

• A powerful 20-volt lithium ion battery can push out a strong stream of 70 pounds per square inch.
• It’s lightweight at under 10 pounds and with a 3-gallon tank.
• The 4-inch mouth lid is easy to fill.

The downsides: You lose a little battery capacity with only 2 amp hours of juice. This one also costs a little more than most lightweight models. 

Our verdict: If you’re willing to pay a little more and stay on top of your battery charge, you can get a powerful, lightweight battery-powered backpack sprayer with the KIMO 3-gallon. 

Specifications:

• Tank Capacity: 3 gallons
• Power: 20 volts
• Maximum Pressure: 70 psi
• Battery Capacity: 2 Ah
• Weight: 9.38 lbs
• Price Range: Medium

Pros:

✓ Lightweight
✓ High power for the weight

Buyers Guide

Do you need a battery-powered backpack sprayer?

Backpack sprayers are a great tool for applying even coats of chemicals to your lawn or garden. If your outdoor space is plagued with weeds, weevils, caterpillars, or any other pest, this contraption can keep them at bay.

Backpack sprayers have a couple key advantages over handheld sprayers. The biggest one is tank size. Most backpack sprayers will carry at least 4 gallons of your favorite herbicide. These tools are also much more powerful than handheld sprayers. With larger pumps and engines, they can simply force out a lot more liquid.

Down below, we’ll cover the different power types so you can decide if a battery-powered backpack sprayer is the way to go.  

3 backpack sprayer power sources

Backpack sprayers rely on three main sources of power: battery, gas, and hand pump. Each has its pros and cons. Here are the key differences to help you make the right purchase for your own spraying needs. 

Battery Power

Battery-powered sprayers are powered by an electric motor with a lithium ion battery. This style offers a lot of portability without the weight or smell of gas. 

Battery-powered backpack sprayers are also better for the environment than gas-powered ones. However, a battery-powered sprayer is not as easy on the planet as an old fashioned pump sprayer. 

One drawback of battery-powered tools: You need to keep the batteries charged. Forgetful people may need to put off spraying and plug in their machine.

Pump Sprayer 

Hand pumps require you to build pressure yourself. Their long pump handles give you a lot of pressure per pump, but you can still expect a mini-workout. 

Why would you want to make outdoor chores harder on yourself? Pump sprayers tend to cost less, and they are much easier on the environment. If you’re interested in saving money, lowering your carbon footprint, and getting some exercise while spraying that insecticide, you might want to consider going hand-pump. 

Gas Engine 

The biggest advantages of a gas-powered sprayer are power and portability. You can get a very powerful jet of pesticides with a gas engine without tiring out your arm. 

However, gas-powered backpack sprayers tend to be louder, heavier, and more expensive than the hand-pump varieties. They also require a lot more maintenance to keep them in good repair. Finally, gas-powered tools release considerable carbon emissions and are not great for the environment. 

Battery-Powered Backpack Sprayers: Key Metrics

Is this your first time shopping for a battery-powered backpack sprayer? Have no fear. Here is a rundown of the key metrics of backpack sprayers and what they mean for you: 

Tank Capacity: Your tank is for storing herbicides, pesticides, or fertilizers, and tank capacity is how much liquid you can store in it. Most backpack sprayer tanks are 4 gallons, but a few have larger or smaller capacities. 

Power: You’ll need a little firepower to move those liquids through your sprayer. Our first assessment of power is simply the battery’s electrical charge, measured in volts. This lets you know how much electrical energy is going to be operating the pump.

Maximum Pressure: The maximum pressure, or the strength of water pressure in the stream, is our second measurement of power. Pounds per square inch (psi) is the standard unit of water pressure. The higher the pressure, the more force your stream has. 

Battery Capacity: Battery capacity is measured in amp hours. One amp hour is equal to a battery’s capacity to run one amp of electricity for one hour. The more amp hours, the more electricity your battery can deliver before you will need to plug it in the charger.

Weight: The weight of backpack sprayers ranges from being under 10 pounds to about 15 pounds. What this means for you depends on how much you’re willing to carry. 

Price Range: Prices for backpack sprayers range widely. As of this writing, the cheapest battery-powered backpack sprayer on our list is about $40 and the most expensive is around $400.

We didn’t list exact prices because they’re liable to change, however, we do let you know where each of them stands (inexpensive, medium, or expensive) relative to all the models surveyed.
