Chapin 60124: 4-Gallon Multi-Purpose Internal Battery Rechargeable Backpack Sprayer, Translucent White, Poly Tank

So I was looking for an electric chemical sprayer to spray bug killer and/or weed killer at a distance of at least 15' and I also needed a good amount of volume of the liquid.All the companies say on their boxes how long their batteries last, how many gallons their tanks hold.BUT None of the companies tell you what the maximum amount of volume it will/can spray per minute with nozzle wide open. I think this unit can spray just under a half of a gallon per minute. If the nozzle was wide open. Which was perfect when I needed the volume.Well this Chapin unit does the job. Sprays a stream of liquid over 20 feet. Of course only when you set the nozzle for a stream spray. You can make the nozzle spray a mist and it will not go that far.The electric pump system stops automatically when you stop spraying. Some other smaller sprayers just keep running until you manually turn off the switch.I have tried smaller electric sprayer units from other companies. They are smaller and maybe easier to handle, but do not spray the volume that I wanted. The area that I just sprayed with my new Chapin only took me 60 minutes to complete when using my other smaller sprayer, it would take me almost two hour and have to refill too many times.Pros:Easy to fill with the large fill opening. Easy to see the volume left. Battery lasted for my 60 minutes. Spray wand was very comfortable and had a long enough hose to be able to reach while spraying. Spray wand hand a lock "ON" feature which was nice. Motor stops pumping when not spraying,Minor Cons:- cannot tell how much battery power is left, but the box says it is good for 1.75 hours. - Wish there was a handle strap at the top of the tank, so I could easily carry it with one hand while it is not on my back. - maybe a spare nozzle to provide a more narrow spray.No major Cons.

This is a game changer for me. I love This! No more manually pumping a handle.

When I unboxed the sprayer, I found kinks in hose but that did not affect sprayer performance at all. It was easy to assemble, with hooked button backpack straps. I connected the sprayer wand, and installed the cap. Even though there was a little charge in the battery, I still charged it overnight. I sprayed about 1100 sq ft of grass area and weeds all around my property. I used about a tank and a half (about 6 gals in total). No problem spraying that much on the single charge at all. The sprayer is easy to operate and the strap across your middle section helps with weight of 4 gallons on your back. The spray trigger lock made spraying very easy. I used to use a smaller hand pumping sprayer, but no more. This 4-gallon sprayer worked perfectly, easy to use, and easy to carry.

Water poured out of the pump area immediately I turned it on. Straight back in the box and back to Amazon. I just could not be bother to pull it apart to see where it was leaking nor call the 800 number. If the QA is so bad that it won't work upon assembly then it is time to move on.

I would recommend this sprayer. This sprayer has great battery life and is great to use. No more pumping. Just aim and spray. I have used it for weed spray and fertilizers. Just don't forget to clean good before switching of coarse. The sprayer is easy to store when not in use. I give it 5 stars and the price is great also.

I bought this 3 or 4 months ago. Yesterday was the first time I used it. It worked great but it leaked right away. Can I tighten something to fix this ?

I have a large farm property that I use RM43 from the Co-Op. I had used a one-gallon hand-pump prior to buying this. What a game changer! I covered 10-times the area in the same amount of time with this gear than I i did with the hand pump version. Since one has to cover yourself from head to toe with RM43, the quicker time on a hot day was a Godsend. It charges fast and has a great and superior spray than the hand version. If I had any negative to say....4 gallons of liquid is heavy when you pick it up, but this is not a problem with this as it straps on your back and is comfortable. I just put it on a table and slipped it on my back. I really like this gear.

Battery operated sprayer. You won’t believe it until you try it. Much much easier to operate than the hand pump. I never really appreciated how fatiguing that was. i’m giving my old hand pumps away.
