It's very powerful and atomizing the spray so I'm getting drift** A: Adjust the nozzle or put different nozzle on. Atomizing is preferred for some tree or shrub spraying, but you need to adjust the nozzle. Good pressure is great. **Q: What all brand batteries work in it? Whats the biggest battery compatible?** A: Takes the same battery as the Ortho Sprayer. **Q: Does anyone else have a problem with having 4 gallons of product but tbe sprayer will only spray 3 gsllons and won't spray the last gallon ?** A: I have the same issue. I believe it's because the internal pick up tube is too high i also need to see if i can have my harness replaced either way still lasts me about 2 house treatments maybe 3 depending on square footage. I'm actually looking to order a second one as mine is finally a year old. Still works after the abuse of arizona residential services. **Q: ¿Trae cargador para la bateria?** A: Si, trae cargador para la bateria. Gracias ## Customer Reviews ### ⭐⭐⭐⭐⭐ Appears to be high quality *by on Reviewed in the United States April 10, 2026* So far, great. This unit is an improvement over the Petra 4-gallon sprayer that only gave me problems. I have used this unit to spray 8 tanks of herbicide so it’s new. What I find so well designed with this sprayer is that it shuts off the pump when the spraying stops. Another design that appeals to me is the built-in bottom stand that helps in stability when I have the unit on my zero turn mower between my legs. It doesn’t tip over. I also ordered and received the 4.2amp battery so now I can spray for a long time. I need the long spray time because I live on a large acreage. ### ⭐⭐⭐⭐⭐ Outstanding sprayer! *by on Reviewed in the United States May 22, 2020* I've been using my sprayer for about 3 weeks now. Just yesterday and today I sprayed 6 acres of avocado orchard where weeds were growing between the rows and between trees. I pretty much worked non-stop each day for 6 hours and the battery never showed any signs of weakening. I do believe they are correct when they say it'll spray 50- gallons on one charge. It doesn't leak, it's very quiet and it's comfortable with it's wide straps and harness.Here's the thing: I am not spraying continuously, I'm spraying individual weeds but at times I'll spray for upwards of 5-6 seconds when I encounter a cluster of weeds. The sprayer kept-up just fine but after 4-5 seconds you will notice a reduction in pressure and it starts 'falling-off', after 8-10 seconds you're at half-power. Of course, this will vary depending which spray head you use.Now let me tell you about my awesome modification! Since you no longer have to pump the sprayer, I decided to convert mine into a dual-sprayer unit! I cut the hose about 6 inches coming out of the tank and then went to Home Depot and bought a plastic/nylon Tee fitting. I then got some fuel-injection clamps (not band clamps), these clamps are smooth and let you really cinch down on the hose. I took another hose and sprayer and now I have a sprayer in each hand! This proved to be incredibly more production and faster working through the orchard. You can also bring the sprayers together to double-saturate a weed as well. Did the sprayer keep-up with having TWO sprayers going? Yes, it did but if both sprayers were going for more then 5-6 seconds I did notice the pressure reduced and I wasn't get as much a mist/spray but instead more streaming. Still, double-sprayer is the way to go, I'm surprised they don't offer this already. ### ⭐⭐⭐⭐⭐ Great for large areas *by on Reviewed in the United States March 25, 2019* The TLDR is that this is an upgrade from my old 2 gallon hand pump carry by my side sprayer I used to use. Definitely makes spraying weeds easier on my larger lot.The good:Holds 2x more than the typical carry next to you type sprayers.Battery operated!!! No more pumping!Battery appears to last a long time. I have used it for about 10 refills and the battery hasn't been charged yet and still works.The wand has a locking mechanism for continuous sprayingSeems sturdily builtThe bad:You can't quite fill it up to the full 4 gallon mark or it overflows in the real worldIt weighs a lot once it's filled up up.The review:I have used this for about 40 gallons worth of spraying RoundUp Pro Concentrate and I have not had any issues with performance of this. It does get pretty heavy when you have it full of whatever you are spraying so I would recommend that you fill it up while it is sitting on something that is a little elevated off the ground. I choose to do this on the edge of my retaining wall that sits about 3ft off the ground. this allows me to not have to bend down as far to pick it up and put it on.It has a chest clip though that really does help take the load off once you have your arms through the straps.As for the actual spray performance, I have only used the fanning spray nozzle (red tip) and it covers what I need it to just fine. Doesn't get clogged at all.Be sure to read the directions and do a good plain water rinse on it after you get done using your chemicals in it.The battery makes the pump run once you squeeze the sprayer handle and it's pretty quiet. Just sort of purrs on your back and then quits once it gets to pressure or you release the handle.If you pay close attention you can start to hear the pump trying a little harder when you start to get low on your chemical and then about 30 seconds later your nozzle starts the doing the sputter to indicate you are pretty much on "E".it did take a time or two for me to remember to turn the switch to the "On" position before I loaded it on my back but once you get used to it you can sort of feel around for the switch on the left bottom side.All-in-all this is a great upgrade from the bottle sprayers I used to use. Now that I have about 3/4 of an acre of just weed areas alone on my property this really saves me time and energy. I always feel accomplished and like I made a big dent in the weeding work when I get done using this for the day. I would recommend this to anyone that has a semi-large walking area to maintain. Anything over an acre of weeds though would probably warrant a real pull-behind sprayer. ## Frequently Bought Together - Field King 190515 Professionals Battery Powered Backpack Sprayer, 4 gal - Southern Ag Surfactant for Herbicides Non-Ionic, 16oz, 1 Pint - Southern Ag Amine 2,4-D WEED KILLER, 32oz - Quart --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/66789771-190515-professionals-battery-powered-backpack-sprayer-4-gal](https://www.desertcart.com.sa/products/66789771-190515-professionals-battery-powered-backpack-sprayer-4-gal) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-06-04*
