A 2-in-1 battery cum manual sprayer is a versatile agricultural tool that combines the convenience of a battery-powered sprayer with the reliability of a manual sprayer. It offers two operating modes, allowing the user to choose between battery-powered operation or manual pumping. In battery mode, the sprayer utilizes a rechargeable battery to power the pump, providing a consistent and effortless spraying experience. This mode is particularly useful for larger areas or extended periods of spraying. In manual mode, the sprayer can be operated by hand pumping, giving the user greater control over the pressure and flow of the spray. This mode is handy for precise or targeted spraying, as well as situations where the battery may be low or not readily available. The 2-in-1 design offers flexibility and convenience, making it suitable for a variety of agricultural spraying applications, including pest control, weed management, and fertilization.
