Using a battery-powered sprayer takes some of the pain out of yard work. We recently tried the Field King 4-gallon backpack sprayer and wanted to see what it could really do.
It feels sturdy and comfortable, even when filled up. We liked how quietly it runs and that you can spray without stopping to pump—huge relief on bigger jobs.
The spray covers a lot of ground and reaches tall plants without fuss. The battery lasts for hours, which is honestly pretty convenient for long sessions.
It’s a bit heavy, though, and not meant for powders. You’ll want to think about what you’re spraying before picking this up.
Check it out and see if it fits your yard care needs.
Overview of the Field King 190515 Professionals Battery Powered Backpack Sprayer
This sprayer’s padded harness and balanced design made it easy to carry around. The battery lasted long enough to handle big areas, so we didn’t have to stop and recharge mid-job.
It works well with different nozzles, which adds flexibility. The metal frame feels tough and stands up to chemicals just fine.
We liked skipping the pumping—saves your arms for sure. When full, it’s heavy, so if you’re out there a while, you’ll notice it.
Cleaning is simple since the parts come apart easily. The spray pressure stays steady, but this isn’t the tool for powders—liquids only.
Key Features
After using this sprayer, a few things stood out. It’s powerful and easy to use, but there are some quirks depending on your needs.
Lithium-Ion Battery System
The battery lasted us about 4 hours on a charge, enough for up to 50 gallons using the standard nozzle. Charging took around 3.5 hours, so you’ll want to plan ahead if you need it again soon.
The 18-volt lithium-ion battery is a solid upgrade from old manual pumps. It’s interchangeable, so if you’ve got spares, you can swap them and keep going.
No-Leak Ergonomic Design
The design is designed to prevent leaks. We didn’t have any messy spills, which is a big deal when you’re working with chemicals.
The steel-coated frame resists rust and damage. The shutoff valve locks tight and seals well, so drips weren’t an issue.
The sprayer fits well on your back and feels stable, but at over 14 pounds, you’ll definitely feel it during long jobs.
Multiple Spray Nozzles Included
It comes with four nozzles: adjustable brass, low and high volume flat fans, and a foaming nozzle. That variety lets you switch between wide coverage and more focused spraying.
You can add other nozzles, too, if you want. The filtration system keeps things from clogging, so swapping nozzles is quick and easy.
Padded Harness for Comfort
The harness is padded and makes wearing the sprayer much more comfortable. The straps adjust easily, so we could get a good fit and avoid sore shoulders.
Even with the padding, 14 pounds gets heavy if you’re spraying all day. Still, the harness helps a lot with comfort.
Ease of Use and Maintenance
We found the sprayer easy to handle right out of the box. No manual pumping means less fatigue and a more consistent spray.
The padded harness kept things comfortable, even on longer jobs. Maintenance was easy too—the triple filtration stopped most clogs, so cleaning was quick.
Emptying and refilling the tank was straightforward. The design helps protect against spills, which is always appreciated.
One catch: you can’t use wettable powders. And since charging takes a few hours, you’ll want to plan ahead. Still, for regular outdoor work, it’s a practical option.
Pros and Cons
We spent some time with this backpack sprayer and noticed both highlights and a few drawbacks.
Pros
The battery-powered design made spraying a lot easier. No pumping meant we saved energy and finished faster.
The battery lasted for hours and the 4-gallon tank let us cover a lot of ground before needing a refill. Comfort is a big win—the harness is padded and didn’t dig into our shoulders.
The steel frame feels tough and holds up to chemicals. Having different nozzles is handy, so you can dial in the spray for each job.
The built-in filtration kept things running smoothly. Controls and shutoff are simple and reliable.
Cons
Charging takes about 3.5 hours, which felt a bit long when we wanted to get back to work quickly. You can’t use wettable powders, which limits your options a bit.
The preset pressure works for most things, but there’s not much flexibility if you want to tweak it. And yeah, the weight is noticeable when it’s full, even with the padding.
Customer Reviews
Most users say the sprayer makes outdoor jobs easier. The battery power saves effort compared to manual sprayers, and the 4-gallon tank is great for bigger spaces.
People find it reliable and pretty quiet. Some wish the battery lasted even longer, especially for huge projects.
A few mention it feels bulky when filled up. For most, it works well, but you might need to take breaks on heavy days.
Summary of feedback:
- Easy to use and saves time
- Good tank size for larger jobs
- Battery life is decent but could improve
- Can feel heavy when full
It’s a solid pick if you want a powered sprayer without much hassle.
Best Applications and Suitability
This backpack sprayer is great for weeds, pests, and fertilizers over medium to large yards. The battery power means you don’t have to pump, which is a real relief on uneven or tricky ground.
The spray duration and pressure handle most garden and landscaping work. But if you need to apply powders or thick mixes, you’ll want something else.
Comfort is a plus, thanks to the padded straps. The nozzle variety lets you adjust spray patterns, though the fixed pressure means it’s best for typical spraying—not super precise or heavy-duty stuff.
