Cordless Power for Effortless Lawn & Garden Spraying
The Chapin 4-Gallon 24V Rechargeable Backpack Sprayer (Model 63924) eliminates manual pumping with a 24-volt lithium-ion battery that delivers up to 2 hours of continuous spraying — roughly 58 gallons per charge — at a consistent 35-40 PSI. The durable, translucent poly tank holds 4 gallons and features a wide 6-inch opening for easy filling and cleaning. Whether you’re applying fertilizer, herbicide, or pesticide across the lawn and garden, this sprayer keeps steady pressure so you can focus on even coverage instead of hand-pumping.
Chemical-resistant Santoprene seals stand up to professional-grade lawn and garden solutions, while a 3-stage filtration system — filters in the tank, cap, and cushion-grip shut-off — keeps debris from clogging the nozzle. Three included nozzles (adjustable brass cone, adjustable poly cone, and poly fan) let you dial in the right spray pattern via the 20-inch wand and 48-inch reinforced hose. Padded shoulder straps ease fatigue during extended use, and the included charger replenishes the battery in just 3.5-4 hours. Made in the USA and backed by Chapin’s 2-year limited warranty.
- No More Pumping: The 24V lithium-ion battery maintains consistent 35-40 PSI pressure for up to 2 hours of continuous spraying.
- 3-Stage Filtration: Filters in the tank, fill opening, and shut-off valve minimize clogging from debris.
- Chemical-Resistant Seals: Santoprene seals handle professional-grade fertilizers, herbicides, and pesticides.
- 3 Included Nozzles: Adjustable brass cone, adjustable poly cone, and poly fan nozzles cover a range of spray applications.
- All-Day Comfort: Padded, adjustable shoulder straps reduce fatigue during large jobs.
