JESIMAIK Battery Powered Backpack Sprayer with Agitator, 120 PSI Handle-Mounted Pressure Control, 4.8 Gallon, 4.0Ah Battery Operated Weed Sprayer with Telescopic Wand & 5 Nozzles for Lawn & Garden — Open-Box, 30% Off

Pressure Control at Your Fingertips – Unlike other sprayers that put the pressure dial on the machine behind your back – forcing you to reach backward and adjust by feel. This electric backpack sprayer features a handle-mounted rotary dial that puts control right in front of you. Adjust from 0 to 120 PSI naturally with your thumb – no awkward reaching, no guessing. Switch from gentle misting to high-pressure weeding instantly

Built-in Agitation System – Herbicides and fertilizers naturally separate over time, leading to inconsistent spray strength and wasted product. Our active mixing system keeps your solution uniformly blended throughout operation, ensuring consistent concentration from the first gallon to the last. For a battery powered backpack sprayer with a large 4.8 gallon tank, this feature is essential for professional results

120 PSI Max Pressure & 0.8 GPM Flow – The powerful diaphragm pump delivers up to 120 PSI – enough for stubborn weeds, fence lines, and driveway cleaning. Stepless pressure adjustment lets you fine-tune from 0 to 120 PSI. With a flow rate of 0.8 gallons per minute, this battery powered sprayer covers large lawns, orchards, gardens and landscaping areas faster

Ergonomic Harness System for Extended Spraying Comfort – This garden sprayer features padded shoulder straps and waist support that distribute weight evenly, reducing fatigue during extended spraying, especially when handling a full 4.8 gallon tank for lawn and garden applications

Complete Accessory Set – The 33-inch telescopic stainless steel wand resists chemicals and reaches tall plants or under dense foliage. Includes 5 interchangeable nozzles (fan, cone, stream, dual, windproof) for everything from wide-area coverage to spot treatment. Wide-mouth fill opening with gallon markings, built-in anti-clog filter, and a 1-year warranty for peace of mind

WARM TIPS: To ensure quality, every sprayer is leak-tested at the factory. You may notice a little water left near the bottom, nozzle or hose – that’s not a used unit, that’s our test in action. If anything doesn't feel right, just feel free to contact us. We’ll make it right.

A backpack sprayer is an essential tool for homeowners, gardeners, and landscaping professionals alike. Designed to be worn comfortably on your back, it allows you to cover large areas with ease, freeing up both hands for better control and precision. Whether you're applying fertilizers, pesticides, or water to your lawn and garden, a backpack sprayer makes the job faster and more efficient than traditional handheld options. It feature an adjustable padded harness and shoulder straps to reduce fatigue during extended use, along with a sturdy tank that holds 4.8 gallons of liquid. A pump handle lets you build up pressure quickly, delivering a consistent, even spray through an adjustable nozzle that can switch between a fine mist and a focused stream. The wide-mouth tank opening makes filling and cleaning straightforward, while a translucent tank body allows you to monitor fluid levels at a glance. Ideal for yards, farms, orchards, and commercial properties, a backpack sprayer is a versatile and reliable solution for all your spraying needs.
