- 120 PSI Max Pressure & 0.8 GPM Flow The powerful diaphragm pump delivers up to 120 PSI enough for stubborn weeds, fence lines, and driveway cleaning. Stepless pressure adjustment lets you fine-tune from 0 to 120 PSI. With a flow rate of 0.8 gallons per minute, this backpack sprayer battery powered covers large lawns, orchards, gardens and landscaping areas faster
- Pressure Control at Your Fingertips Unlike other battery weed sprayer that put the pressure dial on the machine behind your back forcing you to reach backward and adjust by feel. This electric backpack sprayer features a handle-mounted rotary dial that puts control right in front of you. Adjust from 0 to 120 PSI naturally with your thumb no awkward reaching, no guessing. Switch from gentle misting to high-pressure weeding instantly
- Makita-Compatible System & 4.0Ah Battery Compatible with Makita 18V batteries, and we've included a 4.0Ah high-capacity battery and charger. Run continuously for 34 hours on a single charge that's up to 16 full tanks of spraying. Significantly longer runtime than 2.6Ah competitors. For Makita tool users, our battery operated backpack sprayer is the perfect addition to your collection
- Ergonomic Harness System for Extended Spraying Comfort This electric garden sprayer features padded shoulder straps and waist support that distribute weight evenly, reducing fatigue during extended spraying, especially when handling a full 4.8 gallon tank for lawn yard and garden applications
- Complete Accessory Set The 33-inch telescopic stainless steel wand resists chemicals and reaches tall plants or under dense foliage. Includes 5 interchangeable nozzles (fan, cone, stream, dual, windproof) for everything from wide-area coverage to spot treatment. Wide-mouth fill opening with gallon markings, built-in anti-clog filter, and a 1-year warranty for peace of mind
- WARM TIPS: To ensure quality, every sprayer is leak-tested at the factory. You might notice a little water left near the bottom thats not a second-hand unit, thats our test in action. If anything doesn't feel right, just feel free to contact us. Well make it right.

Title: A game-changer for large yards and basements.
Color: Dark Blue
If you are still using a manual pump sprayer for property maintenance, do yourself a huge favor and upgrade to this JESIMAIK electric backpack sprayer. It has completely transformed how I handle weed and pest control around my lawn and yard. The standout feature for me is the native compatibility with Makita 18V batteries. Since I’m already deeply invested in that cordless tool platform, being able to slide in a standard pack and go is incredibly convenient. The power efficiency is excellent—a single charge easily outlasts the 4.8-gallon tank capacity several times over. Performance-wise, the 120 PSI pump is a beast. It delivers a strong, consistent stream right up until the tank is empty, maxing out around 0.8 gallons per minute. You don't realize how much time you waste with pressure drop-off on standard pump-ups until you experience a steady electric flow like this. The inclusion of 5 distinct nozzles and heavy-duty spray wands makes it incredibly versatile, allowing me to switch seamlessly from a wide fan mist for large lawn applications to a targeted jet for precise fence-line weed treatment. Despite hauling nearly 40 pounds of liquid when full, the backpack harness features thick, padded straps that distribute the weight evenly across your shoulders and hips, preventing fatigue. The tank opening is wide enough to pour into without spilling, and the filter screen does a great job keeping debris from clogging the pump lines. It is a rugged, well-engineered tool that turns a tedious multi-hour chore into a quick, effortless project. Highly recommended!

🌿 4.8-Gallon Battery Backpack Sprayer with Handle Pressure Control 💧
Color: Dark Blue
Overview: Good battery-powered backpack sprayer for yard work with strong pressure and long runtime. I've tried this backpack sprayer out a few times and it appears to be made of high quality materials. Good solution for yard work. The handle-mounted pressure dial is the standout design choice here since adjusting pressure on most backpack sprayers means reaching behind your back blindly, which is about as convenient as it sounds 🔧 It runs up to 120 PSI with stepless adjustment from 0 to max, so you can go from fine misting to high-pressure weed treatment without swapping equipment. The 4.0Ah Makita-compatible battery runs supposedly 3 to 4 hours per charge, covering up to 16 full tanks of the 4.8-gallon capacity. The padded shoulder straps and waist support distribute the weight reasonably well when the tank is full, which makes a difference on longer sessions across a larger yard. The 33-inch telescopic stainless steel wand resists chemical corrosion and reaches up into taller plants or down along fence lines without awkward bending 🌾 Five interchangeable nozzles cover fan, cone, stream, dual, and windproof patterns for different tasks. If you're already in the Makita 18V ecosystem this fits right in. Value is pretty good for the runtime and pressure range included.

Love this backpack sprayer!!! Love this backpack sprayer!!!
Color: Dark Blue
This backpack sprayer works great and has plenty of power. I love not having to hand pump constantly, and the battery compatibility with my Makita batteries is a huge bonus. It sprays evenly, feels comfortable to wear, and the different nozzles make it easy to switch between jobs. Makes yard work feel a lot less like punishment. I love that it has a filter screen so you don’t accidentally get yard debris in your tank! Genius! Love this, highly recommend especially if you have a huge property like I do.
