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

Constant pressure without pumping. Excellent for yard or garden

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.

Initially a great product. Used in a residential setting and worked great. Unfortunately after approx. 18 months of use (unit was purchased July 2021) the battery no longer takes a charge and the unit turns on (steady green light) but will not run. Contacted the manufacturer. They confirmed it was out of the 1 year warranty. They said they would likely uphold the warranty if only 1 month or so out but not at the 18 months. The only options is to buy a new one. Now the question is do I want to risk getting another lemon or not.

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.

Can't tell you how many hand-pump garden sprayers I have been through. Have had the Field King for few months now and am very satisfied. The battery generates good internal pressure; it typically takes me about 1.5 hours to work my entire yard and battery has never run out. It is obviously a little heavier than a hand pump sprayer but the included shoulder strap helps a lot.

Per you-tuber "The Lawn Care Nut" you need to buy the blue tee tip to dispense 1 gal per 1000 sq/ft (very common) herbicide application rate of approx. 70 seconds) or so, to accommodate a brisk walking speed. The included red fan tip (probably great for fine spot weed spraying) took approx. 8 minutes by my bucket test.

I love this thing.

I am astounded by the positive reviews for this poorly designed battery-powered sprayer. I am guessing that these reviewers have never before owned a battery-powered sprayer, and are simply enamored by the fact they no longer need to pump a manual-pump sprayer. But in reality, the need to pump a manual sprayer is a very minor burden compared to the other inadequacies of cheap manual sprayers. The most significant deficiency of manual pump sprayers is not the pumping - it is the leaking. Typically, a cheap manual sprayer available for about $10 at a big box store, begins to leak air after a few uses and becomes unusable after just one season. But, if buyers merely think of these manual sprayers as disposable, they are not really that bad. The other deficiency of cheap manual sprayers is the inadequate power behind the spray. But, if the sprayer is used only for small jobs, that should not be a disqualifier either.Unfortunately, this Field King unit, along with similarly priced battery-powered sprayers, suffer those same inadequacies as the cheap manual sprayers. It leaks air, meaning it takes considerable time to re-compress the tank, and there is very little power behind the spray even when fully compressed. The problem is that these cheap battery sprayers are designed to be manufactured cheaply. They work just like a manual sprayer, except instead of pumping air into the tank to create compression, the battery SLOWLY pumps air into the tank to create compression. It is actually much faster to simply manually pump in the air. But the real problem is that no matter how tightly you try to seal the top, some air is going to leak out. And with each use, the leaking gets worse, totally defeating the idea of a battery powered pump.There are much better options, but they cost much more. The better option is a battery powered sprayer that has a more powerful battery AND that constantly "sucks" the liquid out of the tank in the same manner that a spray bottle sprays, rather than simply compress air in the tank. With the sucking (or siphoning) design, there is no need to "compress" the air in the tank, which would inevitably lead to leaking and poor performance. Sprayers with that superior design are typically about twice the price and tend to have larger tanks. But to avoid inevitable frustration, buy the ones with the superior siphoning design. Also, if you buy one with tanks greater than 3 gallons, consider one with wheels.

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.

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

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.

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.

It works great. Only thing is that it is almost identical to the SCOTTS model, but more expensive.
