SideKing 4 Gallon Battery Powered Backpack Sprayer, 100 PSI Adjustable Electric Weed

The SideKing 4 Gallon Battery Powered Backpack Sprayer replaces manual pumping with an electric system designed for lawn care, gardening, dusting, and outdoor cleaning. Delivering up to 100 PSI, it provides steady output that covers wide yards quickly without the continuous arm strain of hand-pump sprayers. It is a practical fit for homeowners and property maintainers who need steady coverage over large spaces.

Powered by an included 2.6Ah lithium battery, the unit runs for up to two hours on a single charge and recharges in three hours using the bundled charger. For larger jobs, the system is also compatible with Makita 18V batteries, allowing you to swap packs and continue working. A built-in digital voltage display tracks remaining battery life, and an automatic discharge protection feature powers down the motor if voltage drops below 14V to prevent cell damage.

Application control is centered around an adjustable pressure knob and a stainless steel telescopic wand equipped with an ergonomic trigger. The sprayer reaches distances over 20 feet, making it easy to hit tall shrubs or wide ground areas. The package includes five different nozzles for varying spray patterns, which store directly inside a secondary compartment on the wide-mouth fill lid.

Carrying a full four-gallon load is supported by double-layer padded shoulder straps to distribute weight across your back. The tank is semi-transparent with molded gallon markings, simplifying chemical mixing and volume checks. One practical trade-off is the overall filled weight, as four gallons of liquid combined with the battery system requires reasonable physical stamina to carry comfortably during longer spraying sessions.

Verdict: The SideKing 4 Gallon Sprayer is an efficient, capable tool for anyone looking to eliminate manual pumping during yard maintenance. Its compatibility with Makita 18V batteries, multi-nozzle assortment, and adjustable 100 PSI output make it an easy recommendation for large-property lawn care and garden spraying.
