This sprayer uses an internal rechargeable lithium-ion battery to power an electric air compressor pump. The pump zero electric pump is designed to provide a more convenient & more consistent alternative to standard manual pumps. It operates by pressurizing the air above the fluid in the tank, which causes the fluid to be pushed through the hose, to the nozzle, & sprayed out. Review: The Cat's Meow!!! - Like most folks, I prefer to use a power tool rather than a hand tool whenever possible. In recent years, rechargeable, cordless tools are usually the best choice. I'm so pleased to have this power sprayer. It was delivered almost two months ago, but I hadn't used it until now. I charged the battery when it arrived, then stored it in the shed during 90° + weather. That's one of the reasons I hadn't used it yet. Too hot. I finally tried it out today, and I couldn't be happier with its performance. I was concerned about the battery remaining charged for so long a time in such high temperatures, but I was pleasantly surprised to find that it was still plenty strong. I can't say how long it would run the sprayer, since I just used it for a two gallon max fill. It ran for about 15-20 minutes, I covered about 800 square feet of gravel driveway and wood chip area with herbicide in that time, and the battery was still strong. The adjustable nozzle made it easy to set the spray width I wanted. The best part was being able to walk around, spraying constantly, without having to push down a pump handle even once. The carrying strap is a nice addition, and is long enough to use over the opposite shoulder from the sprayer. The unit is very well constructed, and I expect it to last for several years. Whoever designed this thing deserves a medal! Review: No more pumping! - Love this pump! Sturdy and easy to use. Good battery life and it does exactly what I wanted it to do. Spot weeding, spraying gutters and deck rails with anti algae solution. I tried other battery operated sprayers and returned them. They either broke after one use or were just non-performers. I had gone back to the good old-fashioned pump until I found this Field King model, just by chance on a YouTube video. ## Features - No more pumping.

You could however purchase a Smith Contractor 190216 2-Gallon Sprayer unit and use the Pump Zero head on that instead of the manual pump head. If you have any further questions please reach out to our Customer Service team at 800-311-9903. **Q: Is 20 psi enough pressure to spray trees 25 feet high?** A: Unfortunately 20 PSI would not be enough pressure to hit 25 feet. We suggest using a Field King 190328 backpack sprayer, which can get up to 150 PSI allowing you to reach up to 30 feet using a straight stream from the poly adjustable nozzle. **Q: Can you use with chlorine** A: Myself I would NOT use chlorine in my sprayer. A lot of people have damaged pressure washers when using chlorine. Chlorine damages rubber used in hoses and fittings. **Q: We have an enclosed patio with no water source. I am looking for something for water plants and general cleanup. Spraying off furniture and pavers.** A: It would be fine to water a plant. Would not be enough pressure to blow dirt off if patio furniture . ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Cat's Meow!!! *by S***. on September 6, 2019* Like most folks, I prefer to use a power tool rather than a hand tool whenever possible.

Good battery life and it does exactly what I wanted it to do. Spot weeding, spraying gutters and deck rails with anti algae solution. I tried other battery operated sprayers and returned them.

No kidding. Just buy it. I did purchase a teejet nozzle to better fit my needs doing lawn chem apps, the flow rate of the included assorted nozzles was just not sufficient to get enough liquid out in a relatively quick timeframe (2 gals/1k sq ft). The nozzle did fix this issue and made the sprayer even better. For reference, I have a ~7500 sq. ft. lot. I use a lot of blue and green marker dye with my sprays, and the tank cleans out perfectly every single time. I've probably ran ~30 gal through it so far and only charged the batter twice. My biggest gripe would be that I can't trigger the pump to start pressurizing and have to wait until it gets really low before it auto-triggers on. This causes the flow to almost cease with some of the included nozzles. The after-market teejet nozzle is made for low variable pressure, so it isn't affected much at all. --- ## 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.pt/products/117360814-field-king-190571-lithium-ion-battery-powered-pump-zero-technology](https://www.desertcart.pt/products/117360814-field-king-190571-lithium-ion-battery-powered-pump-zero-technology) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-02*
