Ublue Battery Powered Backpack Sprayer 5.3 Gallon — 21V Rechargeable, 100 PSI, 8 Nozzles & Telescopic Wand

The Ublue Battery Powered Backpack Sprayer is a rechargeable 5.3-gallon electric sprayer that delivers up to 100 PSI for broad, precise coverage in lawns, gardens, and light agricultural work.

Built to replace manual pump sprayers, this cordless unit combines a 21V 2.6Ah rechargeable battery with a high-efficiency 3800 RPM motor for steady output. It supports long runs on a single charge, includes an adjustable pressure control and eight nozzle options, and is compatible with common Makita batteries for swap-and-go convenience. The design focuses on comfort for extended wear and practical features like a telescoping wand and an integrated storage area to keep accessories organized.

How long will the battery power the sprayer on a single charge?

Typical use yields three to four hours of continuous spraying from the included 21V 2.6Ah battery, depending on pressure setting and nozzle selection. The digital voltage display helps you monitor remaining charge, while built-in low-voltage protection automatically shuts the unit off below 14V to protect battery life.

• 21V 2.6Ah battery included; charger for 110–240V outlets
• Digital voltage readout for real-time battery status
• Auto shutoff at low voltage to preserve battery health

What spray performance and reach can I expect from this sprayer?

The motor can produce up to 100 PSI, giving you options from fine mist to longer-range streams. An adjustable pressure knob lets you dial in the output for delicate plants or for heavier chemical application, while the telescopic wand extends up to 39.3 inches to reach high or awkward spots.

• Onboard storage compartment for nozzles and accessories
