Field King 190571 Lithium-Ion Battery Powered Pump Zero Technology Sprayer, 2-Gal, White

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!

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.

Had a backpack sprayer that needed pumped constantly to maintain pressure while spraying chems on the lawn... purchased this and omg I'll never touch a manual-pump sprayer again. 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.

The tank is heavier than pump up tanks. I sprayed 7 tankfuls today so I know a charge lasts at least that long. The design is great. Pumping air into the tank rather than pumping the spray works well. I used he fan nozzle for my weeds. You also get a cone shaped spray with a different nozzle. There is one I haven't figured out yet, and there is a brass one that adjusts like we are used to with the hand pump sprayers. When I was done and had cleaned up, I put the adjustable brass nozzle on so I could report. First, I opened it all the way up so I'd get nothing but a straight stream. With the pump up to maximum where it shuts off, I got a straight stream out about 20 feet. Then I shot the stream straight up. I got maybe 13 or 14 feet straight up. I was sitting in a chair so the nozzle was maybe 4 feet off the ground, and the tank was on the ground. Then I tightened the nozzle down to where I had a usable stream that was 3 or 4 inches across at something closet to 15 feet. Straight up, that adjustment got maybe 12 feet. If I were standing and reaching, I could get 15 or 16 feet. That allows me to spray the tops of the trees in my small orchard. The wand seems strong. The hose is better than anything I've seen on a hand pump sprayers. I would have liked the hose to be a foot and a half to two feet longer. I put my tank on a small dolly. I also would have liked a 3 or 4 gallon tank. Regardless, I'd buy this again. Pump Zero did the job well. . . . and the disclaimer. I didn't get squat for this review. I paid for the sprayer. The sprayer did a good job for me so I said so.

It is a reasonable price for what you get. Works pretty good because you don’t have keep pumping. It only maintains about 10psi vs the stated 20 psi. One of the problem with this sprayer is that it uses air pressure by the screw on top vs other sprayers that use a liquid pump to maintain pressure. Another problem is the charger provided mentions not leaving the battery powered head on the charger. If I would have known what I know now, I would have spent a little more on a better battery sprayer.

Wow, this sprayer is such a pleasure to use. I use it to spray my roses and heucheras with antifungal solution and then at another day during the week I use it to apply my fertilizer as a foliar spray. I was using a handheld spray bottle to apply myantifungal in the past and it took over two hours. Now with a full charge this sprayer gets the job done in twenty minutes!! I know I should be comparing this to a manual pump sprayer but I just can't get over how much less messy this is and how much time I am saving. The same applies for my foliar fertilizer. I used to make batches of fertilizer in five gallon buckets and then water it into the soil. I have a ton of plants to water and feed and it would take me over three hours. With this battery powered sprayer I get the job done with a lot less effort in about thirty minutes!!! I am loving the time I am saving by using this sprayer. I hope it gives me years of reliable use. I will provide updates should anything change. For now I HIGHLY recommend this sprayer for anyone who wants to save a lot of time. UPDATE: As of September 14 summer is coming to a close and my sprayer has worked perfectly all summer long. I think I only needed to charge it a total of three times. I used it approximately twice a week for the most part. I went back to watering my fertilizer into the ground the old fashioned way. So toward the end of summer this was used mainly for applying anti-fungal solution mixed with water to my rosebushes and heucheras.

First off I just want to say originally I really liked this product. I was very pleased with the price and what I received. First summer it worked great and then it sat over the winter. Then the following summer came and the battery wouldn't charge right and the light flashes on n off. Needless to say I have forgotten to leave a comment but I had just remembered . So I am . If every one of there products work like this then no it's not worth it . Go buy a expensive one that will run correctly the next 20 yrs. This one only ran right one summer. I got it 2021 and haven't been able to use it correctly sense summer of 2022. It's now end of summer 2023'. If they somehow was to send me a new battery and prove to me this was a one off then I'd give em a 10 or 5 stars cuz I was very happy till the battery wouldn't take a charge no more. I never even used it much either. That's what's sad.

I was done with the manual sprayers so I purchased this one by Field King. The sprayer is well built and the extra nozzles are great. The Handle compressor takes a while to charge, but once its charged, its so easy to use and spray with about 20psi of pressure. At times when I was nearing a recharge, I did feel that the pressure was decreasing. Its a minor flaw. Just ensure that when you are about to use it, put the handle on a charger and charge till the light goes green. On another point, once the handle is charged and the light goes green, take it of the charger. This is not a unit you can leave over night to charge. The Pump Zero handle/compressor is the being used by many brands, Field King is one of them. Great Sprayer for the price.

Works well, battery last for a long time. I used to have a backpack sprayer and I was tired of getting chemicals on my back. Many people comment that the Scotts is the same for cheaper except that the Scotts come with one nozzle that you rotate to get different sprays. People have been complaining about this nozzle getting stuck so I went for this one instead which comes with many different nozzles. One caveat as a reviewer mentioned, do not leave plugged in after the battery is fully charged as this is a dumb charger that keeps charging even after the battery is full. If you do, you'll destroy the life of the battery.

Funciona maravillosamente

Cumple con su objetivo, sin embargo no estoy del todo satisfecho, ya que es muy difícil poner la varilla en su lugar y que entre lo largo de la varilla y lo mucho del cabeza, es muy tradado y difícil acomodarla y termina en el suelo la mayoría de las veces. Eso la hace incomoda de usar, ya que se corre el riesgo de pisar la varilla y esta no es resistente lo cula provocaría su ruptura

A true back saver. Not only that. Are you using one of those pump "gadgets" that you have to pump every 3 minutes and then it gives you a little DRIP to put on your weeds? I would "scream". I went on the hunt and found this. Love it. The battery charges up quite quickly and lasts for as long as I need it. My yard is all red clay rock and so the weeds come up through the rock. I would pump the OLD gadget I had been using for years to get my tiny spray for one weed. This 2 gallon sprayer allows me to get the job done in 1/3 the time with NO pumping and a great spray. BUY IT! So easy to carry around.

Utilisé a 2 reprises avec remplissage a 2 gallons chaque fois, et la batterie est encore bonne. Facile a utiliser, le seul bémol, la courroie est un peu étroite et inconfortable quand le réservoir contient au moins 2 gallons ou plus. Accomplit mon travail de contrôle des araignées autour de la maison, du gazebo et de la remise en 1/2 heure, wow je ne m'en passerait plus.
