PetraTools’ HD4050 is an easy-to-use, 4-gallon battery-powered backpack sprayer with a long list of industry-leading features. Not only will you never pump again, you’ll enjoy 6 to 8 hours of spray time on a single battery charge. This is 4 times longer than the spray capability of regular lithium battery sprayers. With our 5 included nozzles, this is the perfect sprayer for lawn and garden maintenance, greenhouse use, or commercial applications. At PetraTools, our sprayers are built rock solid and designed with superior functionality in mind.

The heavy-duty wand has a locking trigger for continuous spraying and a wand clip, so you can secure it to the tank when not in use. Additional beneficial features include a wide mouth and tethered lid, adjustable pressure knob, and plug-in battery box design. Other sprayers are labor consuming, inefficient, and provide uneven and unreliable spray applications, but a PetraTools’ sprayer will revolutionize the way you spray.

Great product

Easy setup. Online video very informative. Really like the adjustable power of the very quiet motor.

Works awesome. Nice consistent flow.

Easy spraying of anything

Had a backpack manual pump sprayer which required allot of continual effort.
Using the Petra battery operated sprayer compared to the manual sprayer you have to pump by hand was like winning the lotto.
Just pull the trigger and with the powerful pump you can easily cut your spraying time in half.
Once you try the Petra electric sprayer you will ask yourself why you didn’t buy one sooner. Excellent reliable sprayer.

This is a great sprayer. 4 gallons might be a little heavy for my poor body but after I spray a gallon or two it's just fine. Great features and easy to use. And I like the assortment of spayer tips.
The only problem I had was the battery was totally discharged when I received the sprayer - even though it was supposed to be shipped fully charged. Other than that, I LOVE this machine!!!!
