SideKing 4 Gallon Battery Backpack Sprayer, Makita 18V Compatible, 100 PSI

The SideKing 4 Gallon Battery Powered Backpack Sprayer is a portable electric sprayer that delivers up to 100 PSI, a 4-gallon tank, and Makita 18V battery compatibility for faster, easier lawn and garden spraying.

Replace tiring manual pumping with a battery-powered sprayer designed for homeowners and pros who need steady pressure, longer run time, and quick refillability. This unit pairs a 4-gallon semi-transparent tank with a rechargeable lithium battery and a stainless steel telescopic wand so you can treat beds, borders, and hard surfaces more efficiently than with hand-pump models.

How long will the SideKing sprayer run on a single charge?

With the included 2.6Ah lithium battery, typical continuous spraying lasts up to about two hours depending on pressure setting and nozzle choice. A digital display shows remaining voltage so you can monitor charge during use, and the charger refills the battery in roughly three hours for a fast turnaround between jobs.

• Up to ~2 hours runtime on moderate settings
• 3-hour full recharge time with included charger
• Digital voltage readout for real-time battery monitoring
• Automatic cut-off below 14V to protect battery life

What spraying power and coverage does it provide?

The SideKing delivers variable pressure up to 100 PSI so you can switch from fine misting to longer-range jets for cleaning or spot treatment. A spray reach exceeding 20 feet and a 4-gallon tank reduce trips to the refill point, making it suitable for large lawns and multiple beds in a single session.

• Adjustable pressure knob for precise control
• Spray range over 20 feet at higher pressure
• 4-gallon tank minimizes refill frequency
• Five interchangeable nozzles for different spray patterns

How does the design help comfort and usability during long jobs?

Ergonomics are central to the SideKing layout: double-layer padded shoulder straps and a backpack frame reduce fatigue and distribute weight evenly. The semi-transparent tank with gallon markings and a wide-mouth lid makes measuring, mixing, and refilling straightforward while a secondary lid houses spare nozzles for quick swaps in the field.

• Padded shoulder straps ease long-duration wear
• Semi-transparent tank with visible gallon markings
• Wide-mouth fill opening and secondary nozzle storage lid
• Stainless steel telescopic wand with comfortable trigger

Is this sprayer durable and compatible with my batteries and tasks?

The unit is built for regular outdoor use with waterproofing features and a rugged battery system. It’s compatible with Makita 18V batteries for quick swaps if you already use that platform, and comes with a charger and one-year warranty so you can start using it right away and get support if needed.

• Makita 18V battery compatibility for shared battery ecosystems
• Waterproof design for use in damp conditions
• Includes charger, five nozzles, and a 2.6Ah battery
• One-year warranty and online customer support

Who is this for? The SideKing 4 Gallon Battery Backpack Sprayer is well suited for homeowners with medium-to-large yards, landscaping contractors who need portable pressure without hoses, and hobby farmers wanting a reliable tool for spot treatments, cleaning, and pest-control tasks. If you value adjustable pressure, longer runtime, and compatibility with Makita 18V batteries, this sprayer is designed to save time and reduce physical strain compared with manual pump units.
