Ublue Battery-Powered Backpack Sprayer 5.3 Gallon — 100 PSI, Makita-Compatible

The Ublue Battery Powered Backpack Sprayer is a 5.3-gallon electric garden sprayer that delivers up to 100 PSI of adjustable spraying power with Makita battery compatibility for long, comfortable yard work.

Designed for homeowners, landscapers, and small-scale agricultural use, this rechargeable backpack sprayer combines a rugged 5.3-gallon tank with a high-efficiency 3800 RPM motor and a user-friendly digital display. It ships with an integrated 21V 2.6Ah battery and charger for immediate use, while also accepting Makita-compatible batteries so you can swap power packs quickly on larger jobs. Ergonomic padding, an adjustable waist belt and shoulder straps, plus a breathable back panel reduce fatigue during extended spraying sessions.

How long will the battery run and how do I monitor charge?

The sprayer is engineered to run continuously for roughly 3–4 hours on a full charge with the included 21V battery under typical conditions. A smart digital voltage display on the unit shows remaining battery life so you can plan refills or battery swaps without downtime. Built-in discharge protection automatically powers the unit off when voltage drops below 14V to protect battery health and prolong service life.

• Included 21V 2.6Ah battery and 110–240V charger for immediate use.
• Makita-compatible battery bay for quick swaps with existing tool batteries.
• Digital voltage readout for real-time battery monitoring.
• Auto-off below 14V to prevent deep discharge damage.

What spraying performance and reach can I expect?

The motor delivers up to 100 PSI and runs at up to 3800 RPM, suitable for fine misting or stronger, longer-range streams depending on nozzle choice. An adjustable PSI knob lets you dial in pressure for delicate plants or targeted application. The kit includes eight nozzle types and a telescopic wand that extends to 39.3 inches, helping you reach high, low, and awkward spots without bending or climbing.

• Maximum 100 PSI output with variable pressure control for task-specific spraying.
• Eight interchangeable nozzles for mist, spray, and narrow streams.
• Telescopic trigger wand extends to 39.3 inches for extended reach.
• High-efficiency 3800 RPM motor for consistent spray patterns.

Is the sprayer comfortable and built to last for long jobs?

Comfort features include thickened, widened shoulder straps, an adjustable padded harness, a breathable back panel, and a supportive waist belt to distribute weight evenly. The tank and motor housing are constructed for durability and repeated outdoor use, and an upgraded storage compartment keeps nozzles, wands, and accessories organized during transport. Together these elements reduce strain for hours of continuous operation.

• Padded, adjustable straps and breathable back panel for extended comfort.
• Supportive waist belt to stabilize load while moving.
• Durable motor housing and tank materials suited for yard work.
• Onboard storage for accessories and spare nozzles.
