PetraTools Battery Powered Backpack Sprayer 4 Gallon - 6 Hours Long Battery Life & Padded Straps for Comfort - HD4000 Electric Backpack Garden Sprayer with 6 Spray Nozzles & 90PSI Adjustable Pressure

3-Year Review This rechargeable battery-powered backpack sprayer has been an outstanding investment. It features a durable, well-built design and comes with multiple spray nozzles, making it versatile for a wide range of applications. I primarily use it for applying pesticides and weed killer, ensuring I thoroughly clean it between uses. Compared to a manual pump sprayer—which previously took me 1–2 hours per job—this unit has significantly improved my efficiency. The battery-powered system eliminates the need for constant pumping, and does it on its own allowing for consistent pressure and a more powerful spray. One of its most valuable features is its extended reach, enabling me to spray up to 10–15 feet if not more when needed, such as reaching higher areas without wasting product. With this sprayer, I can now complete most jobs in under 30 minutes. After three years of use (approximately 10 times per year if not more), it remains in excellent condition and continues to perform reliably. I highly recommend this product to anyone looking to save time, reduce effort, and improve overall efficiency.

Purchased this battery backpack sprayer in March 2024. I have been impressed with the batteries longevity lasting 6 hours or more on a charge. Using the correct nozzle I can easily spray nearly 20 feet up into the trees for insect control. With a full tank of 4 gallons the capacity is sufficient and is well balanced on the shoulders making it easy to use. It was an excellent value and I would not hesitate to purchase one again. This year (2026) the battery would not charge so I contacted Petra Customer Service and spoke to Christina. She didn't hesitate to take care of my problem. I am totally impressed with their service and attention to the needs of their customer. Not to mention the fact that an actual person answers the phone. Thanks Christina for your excellent service!

This is pretty awesome. It's US-made, works as advertised, and is high-quality. The spray time, build quality, and durability aren't just marketing claims about what it can do; it works as advertised. The customer service is top-notch. We accidentally short-circuited the power pack on an out-of-warranty unit, and Anne in tech support sent us a new replacement anyway, just to get us back up and running. We like these so much, we bought two. It's definitely worth what it costs.

Customer support (Christina) is outstanding and the sprayer is great as well. I am giving 5 stars specifically for the customer support and would give the product 4 stars. The product is outstanding and is so much better than the old pump sprayer I previously used to spray my lawn for moss and weeds. 4 gallons is 2x the capacity (at little heavy but worth it; also the product has nice padded shoulder straps) and the 5 heads and continuous pump from the electric motor cuts the application time by around 4x the pump sprayer. Overall product construction is very good. However, I have had is with leaks on the hose both at the connection to the sprayer pump/tank and at the wand. Fortunately, Christina in customer support immediately shipped me the hose replacement and wand on/off portion at no cost under warranty. IMO, the product should have metal threads on each end of the hose connection. They already have a metal threaded connection from the hose to the tank but the hose to the wand is plastic and can easily tread if overtighten (which very easy to do especially if having a light leak). If PetraTools upgraded the wand to hose connector to metal, I believe the product would be 5 stars all day long!

I have had this sprayer since August of 2024. My lot is 1.5 acres, too big for a hand pump sprayer and not big enough for a tractor sprayer. I love it. I spray herbicide, insecticide and pre-emergent. There are a number of different spray heads. I can efficiently spray large patches of gravel, or get up high in the fruit trees. I pulled it out to get ready for spring this last Saturday. I had left it on over the winter, so the battery was dead. I plugged in the charger and the light on the charger wasn't lighting up. I tried it on several outlets, to no avail. I called Petra Tools and spoke to a lovely person named Anne. She had me try a couple of things and then sent me a text asking for my order number, I got on to Amazon, looked up my order history and sent her a screen shot. She immediately replied and said that she has put put a new charger in the mail and I should have it in the next couple of days. I love outstanding service. The sprayer is great and so is the customer service.

Product is amazing and seems to be nicely built and works as described. I had some technically difficulty from the start (user error), but I called their customer service line, spoke with Anne and she guided me along the way and answered all my questions promptly. It’s wonderful when you purchase a product and get to actually deal with English speaking customer service personnel and not somebody overseas! If you’re looking to up your game and go to backpack spraying for any application.. definitely give this product some consideration! You’ll be throughly pleased with your purchase and it’s backed by a team that will do right if any problems arise!

Worked great one time. I used it to spray weed and grass killer on the grass in my gravel driveway. It worked flawlessly. I put it up over winter and it no longer works. The battery is fully charged but it won’t make a sound or function properly. Anne with customer service has been great. She’s sending me out a new battery and charger to hopefully fix the issue.

This is a great product and more than delivers what I purchased it for. Easy to setup and easy to use. Couldn’t get the registration scan to work so I contacted Anne from customer service and she took care of it after I sent the purchase information. Great product and outstanding service!
