ALIENTABI Battery Backpack Sprayer 4-Gallon — 36/65 PSI Two-Speed, Rechargeable for Lawn & Garden

The ALIENTABI Battery Backpack Sprayer is a 4-gallon, battery-powered garden sprayer that delivers adjustable 36 or 65 PSI flow for cordless, hands-free watering and treatment tasks.

Designed for homeowners and small-landscape professionals who want to replace manual pumping with battery-driven consistency, this backpack sprayer balances run time, pressure options and comfort. Rechargeable and easy to load, it runs for more than two hours on a single charge and reaches spray distances up to about 26 feet, making it useful for spot treatments, perimeter spraying, and general watering where mobility matters.

How does the two-speed system change spraying performance?

The sprayer offers two pressure settings — 36 PSI for low-pressure applications and 65 PSI for higher-pressure needs — so you can switch between gentle watering and stronger spray patterns. Changing settings is done with a simple flip switch, giving quick control without changing nozzles.

• 36 PSI: gentler misting for seedlings and delicate plants
• 65 PSI: higher force for foliar coverage or longer-range spraying
• Quick switch operation for rapid task changes
• Stainless-steel wand helps maintain steady stream at both pressures

What are the battery life and maintenance steps?

The unit runs for over two hours per charge under typical use and includes a removable battery pack that you can recharge separately from the sprayer. Routine maintenance is straightforward: rinse the tank after use, inspect seals, and keep the battery contacts clean to prolong life.

• Removable battery for off-unit charging and easy replacement
• Over two hours run time on a single charge (actual time varies by use)
• Simple tank flush after each use to avoid residue build-up
• Factory leakage checks performed before shipping

What build features make it comfortable and durable?

The backpack harness uses wide, deeply cushioned shoulder straps to reduce strain on long jobs, while the tank shape and weight distribution are designed for stable carrying. Durable components like a Viton-sealed high-pressure gun and a threaded stainless-steel wand resist corrosion and wear from common garden liquids.

• Wide padded straps for reduced shoulder fatigue during extended tasks
• Viton seals on the trigger gun for chemical resistance and durability
• Threaded stainless steel wand for leak-free connections and longevity
• 4-gallon tank capacity for fewer refills on medium-sized jobs

Can it handle different garden tasks and products?

This sprayer is intended for a range of non-pressurized garden liquids including water, liquid fertilizers, and many common lawn-care solutions. Always follow product labels and local regulations when applying pesticides or herbicides and rinse thoroughly between different liquids to avoid cross-contamination.

• Suitable for watering, feeding, and many landscape maintenance liquids
• 4-gallon capacity reduces refill frequency for medium yards
• Adjustable pressure options adapt to different application needs
• Rinseable tank and removable battery simplify transitions between products

Who is this for: The ALIENTABI Battery Backpack Sprayer is a practical choice for homeowners with mid-sized yards, landscapers doing spot treatments, and anyone upgrading from manual pump sprayers who wants cordless convenience. It’s geared toward users who value adjustable pressure, a removable rechargeable battery, and a comfortable harness for longer chores.
