SideKing 15.1 L Battery Backpack Sprayer - 100 PSI Cordless Garden Sprayer with Charger & 5 Nozzles

The SideKing 4 Gallon Battery Powered Backpack Sprayer is a high-pressure, battery-operated garden sprayer that delivers up to 100 PSI for fast, hands-free spraying of lawns, gardens, and outdoor surfaces.

This cordless backpack sprayer combines a spacious 4-gallon tank with an efficient lithium battery system and adjustable pressure control so you can cover large areas without the fatigue and interruption of hand pumps. Designed for homeowners and light commercial users, it includes a charger, five interchangeable nozzles, a stainless steel telescopic spray wand, and a semi-transparent tank with clear gallon markings for easy mixing and monitoring.

How long will the battery run and how is battery life managed?

The unit includes a rechargeable lithium battery that supports long runtime and a quick three-hour recharge. A digital voltage display shows remaining power at a glance, and built-in discharge protection shuts the sprayer off below 14V to preserve battery health.

• Includes 2.6Ah rechargeable lithium battery and charger.
• About up to two hours continuous spray per charge (typical use).
• Digital display for real-time battery status.
• Automatic cutoff prevents deep discharge below 14V.

Is the sprayer comfortable and durable for extended use?
