Field King 190571 Lithium-Ion Battery-Powered Sprayer — 2-Gallon, 20 psi

Overview

Meet the Field King 190571, a 2-gallon, battery-powered sprayer designed to handle water-soluble solutions with a compact air-assisted pump. This setup helps deliver a reliable spray without manual pumping, making weed prevention, remediation, pest control, fertilizing, and watering more convenient for homeowners and professionals alike.

Power and performance

A built-in lithium-ion battery drives an integrated compressor, maintaining a steady pressure for consistent nozzle output. Users can cover more ground in less time, thanks to reduced pumping effort and a stable spray flow.

• No more pumping: the compressor keeps the flow steady for uniform coverage.
• Approximately 20% time savings on larger spraying tasks.

Design and usability

The teardrop-shaped tank lowers the center of gravity for stable handling, even when moving across uneven terrain. A built-in nozzle storage area protects components, while a 21-inch poly wand with Viton seals resists chemical wear across seasons.

• Premium shut-off with comfortable grip, lock-on option, and an easy-clean inline filter.
• Pressure release valve for safe depressurization before opening the sprayer.
• Includes four nozzles (brass adjustable, two flat fans, and a foaming nozzle) and accepts Tee Jet nozzles.
• Limited 1-year warranty with free replacement parts; assembled in the USA with global components.

What you can spray

Designed for water-soluble liquids used in weed prevention, weed remediation, pest control, fertilizing, and watering. Always follow label directions and wear appropriate protective gear as required by the product.
