SideKing Battery Powered Backpack Sprayer 3.2 Gallon, 0-80 PSI Adjustable Pressure Sprayer Compatible with Makita 18V Battery, Electric Sprayer with Wand, 5 Nozzles, 2.0Ah Battery&Charger Included

This sprayer works very well. The wide hose end sprays a mist which is perfect for putting out spot fires, the main reason why I purchased it (I am a retired firefighter). It also shuts off the pump motor when the nozzle is closed, a question that AI could not answer, so the pump won’t burn up. It is very heavy so I only put one gallon of water in to test it. The mist is so fine that it would cool down a small fire almost instantly, outdoors or inside. If I need it I will carry it on my riding mower outdoors for fire fighting. It is a great bargain!

For small-garden spot spraying of herbicides I typically use a 1-gallon low-flow-rate Li-ion powered hand wand sprayer. However, when the area grows to the entire lawn or larger trees and bushes, one needs to move up to a higher flowrate, larger capacity, high-pressure electrically-powered backpack sprayer. The SideKing unit attracted me by its reasonable price and use of a Makita-style Li-ion rechargeable battery, which matches that in some of my other power tools. I also have a larger cart-mounted, battery-powered spray rig with 100 feet of house, which I use on our ranch for spraying fruit trees in our family orchard. In testing this SideKing unit, I was pleased with the range of the pressures and its ease of pressure control and the nice spray wand, which didn't experience any leaks...a common problem with other higher-pressure sprayers. The SideKing tank has a nice carrying handle for smaller jobs where you don't want to wear it on your back, a compartment for storing parts, and a nice large fill port with convenient screen filter for preventing contaminants from getting into the spray-tank solution. The unit comes with a collection of different spray nozzles that provide a useful range of spray patterns, but for my applications I purchased (from Amazon) a Bmiroamdfe high pressure misting nozzle that provides an adjustable pattern all the way from a single 20-foot stream to a nice 20 degree solid cone for pre-emergent application. This Bmiroamdfe head fits perfectly on the SideKing wand's M14-1.5mm nozzle thread and also comes with two M14-1.5mm angled couplers to angle the sprayhead downward for ground-level spraying; also included are two useful female M18-1.5mm to male M14-1.5mm thread adapters to allow use on wands with a M18-1.5mm nozzle interface. Although the overall engineering of the SideKing unit was excellent, I found two minor things a bit annoying: The first was that the short connecting hose between the tank and the spray wand has no rotational flexibility, which is needed to allow the handle to easily conform to the way one holds the wand. My larger orchard unit has quick-disconnect couplings where the hose attaches to the tank and to the spray wand which provide this adjustability, and it's a huge improvement. To remedy this situation I purchased M18-1.5mm quick-disconnect fittings to fit the thread used by SideKing sprayer for its hose fittings. However, this took some custom machining, as the purchased quick-disconnect fittings from Amazon came with a cone seal that had to be modified to a gasket seal (see photo). The added quick-disconnects greatly improved the comfort of the wand unit and provide the ability to quickly remove the wand and hose from the spray tank. The second minor annoyance was the lack of space to grab onto the Makita-style battery when trying to remove it from the unit for charging. I love the fact that the battery is removable so I can take it inside during winter months or whenever I'm charging it, a feature not available in my larger orchard unit with built-in lead-acid battery. However, in my received unit the Makita-style battery slides in very tightly and there is insufficient room in the SideKing's access hole to grab onto the battery to pull it out. This style battery lacks a ledge or physical feature to grab onto. Perhaps what is needed is some sort of extraction tool with a hook to reach in behind the battery to pull it out (see my photo sketch). In testing out the unit, one of my first tasks was to measure the volumetric flowrate of the sprayer to judge how much spray area of turf to cover in a given period of spraying time. Although Save A Drop (on Amazon) makes a convenient flow meter for attachment to a garden hose, I've not found any that attach to the common M18-1.5mm (straight thread) that is used for the SideKing spray-wand-to-handle interface. Another common spray-wand thread is the M14-1.5mm, which is used by SideKing for its spray-nozzle attachment threads. To resolve this issue I purchased a set of brass Male (from Joywayus on Amazon) and Female (from Hooshing on Amazon) 1/4-18 NPT (American tapered pipe thread) to Garden Hose thread (GHT) brass adapters and remachined the adapters to interface with a M14-1.5mm interface thread. By using the M14-1.5 thread and some thread adapters, my flowmeter can then be used with wands with either the M14-1.5mm threads or the M18-1.5mm threads. The common M14-1.5mm spray-wand thread generally has an outside diameter of around 0.535", about the same as the maximum diameter of the American 1/4-18 NPT tapered thread. Since the 18 tpi American and 1.5mm metric thread pitches are essentially the same in these short-thread-length applications, the 1/4-18 NPT (tapered thread) fittings have basically the correct thread pitch, they just need to have the taper removed by remachining the thread to the desired 0.535" diameter of the M14-1.5mm straight-thread fittings. To attach these to the SideKing wand and valve-handle, I used a pair of M14-1.5mm to M18-1.5mm male-to-female and female-to-mail adapters which I had in my inventory of sprayer parts. One other important point is that straight-thread fittings are not self-sealing like tapered threads and must rely on a pressure gasket for sealing. For higher pressure systems (>40 psi) these gaskets must be prevented from being extruded out of the sealing joint by the high pressure. This is done by constraining the outer diameter of the gasket by placing it in a groove or cavity with a fixed outer diameter (typically around 0.670" for the M14-1.5mm nozzle fitting). Shown in the attached photos are the completed flowmeter adapters with their new straight threads and gasket-groove for the male M14-1.5mm fittings. The SideKing sprayer with this integrated Save A Drop flow meter worked very well to measure the total spray quantity dispensed and to measure the flowrate of the various nozzles. To its credit, the SideKing unit's spray-wand and spray-nozzle fittings all implement the needed gasket constraining grooves and have been leak free as a result. My complements. In summary, the SideKing backpack sprayer works very well, so well I bought a second unit for the ranch to complement my larger cart-mounted unit. With my custom adapters, they're now my go-to sprayers for a number of medium-sized spray jobs. Definitely recommended.

Only used it once so far but it worked great. The directions aren't much help, but I still had zero issues assembling it. Everything screwed together without a problem, and no leaks. I filled the 4 gallon tank all the way up and at first it took a little bit to get the air out of the pump, but some simple rocking the tank around took care of it pretty quickly. Sprayer worked great, plenty of pressure, hardest part was lifting the 4 gallons on to my back. I'd recommend sitting it on a table, tailgate or something elevated so you can easily slip your arms into the strap. I used up the entire 4 gallons and the battery still read full charge so that was awesome. My biggest problem is the interchangeable nozzles. I didn't change the nozzle, and that's my point, I felt locked in to my choice. I'm not going to carry around a bunch of nozzles and sawp them around as needed. One adjustable nozzle would be a much better option. That being said, I am very satisfied thus far.

Arrived on time, undamaged. Took about an hour to put together, not that it was complicated at all, and hardly any parts. BUT I read the problems other folks seemed to have in here (and elsewhere) and took my time and solved them. The sticky battery door is supposed to slide UP AND DOWN not any other kind of way. Pull the small tab outward with your thumb just enough and press upward with your other fingers at the bottom and it works. I noticed some plastic flashing around the edges of both the door and the tank itself, so I trimmed them off with a Stanley knife, and just for fun touched up the edges with just a little dab of silicone lube. Works just fine thankyou. Hard to remove battery, as others have noticed. It slides on the usual "rails" ok, but theres two clips deeper inside the battery compartment obviously designed to hold it in place. Had to work a bit to get it out, but once I realized they're there to keep the battery in place, I got the knack of it. Took about 3 hours for the charger to turn from red to green. I decided which nozzle I would use most of the time, and finished with about 4-5 inches of water, enough to cover the strainer intake in the bottom by a few inches. Took it outside and amazingly, it worked just fine. I say amazingly, because I fully expected it not to, and to lea k and/or not run.. FWIW, this unit replaced another one (the big yellow brand that has been making all kinds of sprayers for years) that did yeomanlike service for almost 20 years, until I got really tired of fiddling with the wiring to get it to charge. That one cost MORE than this did when I bought it years ago. Sent an email for the warranty registration with the AMAZON order # just on general principles, assume it was received, but no acknowledgement. The true test of this is when I fill it and use it for a few hours. BTW, I removed the shoulder straps, I don't use them, carried enough on my back in the Army. No way they can ever be made "comfortable". The thing either is bungeed to a small yard cart attached to the riding mower, or, mostly, bungeed to a hand cart with fat tires for use around the house. Gave it 4 stars because although it "seems" to be alright, you shouldn't have to fiddle with it to assemble it, or problem solve along the way. Naturally, the instructions could be clearer, especially the "Makita replacement battery charger" warning. It was certainly cheap enough, so time will tell. Something tells me it isn't going to last 20 years like the one it replaced. OTOH, I don't think I'll last another 20 either, so maybe it'll be just fine. Update. Got acknowledgement of warranty. UPDATE went out early this am to use it for second time. Wouldn't turn on. Turned it of and on a couple of times and finally did. Pump sputtered and I assumed it was air in the sprayer hose, but it never went away, Then almost immediately I noticed leak from hose connection to tank. It was tight, not sure why it leaked. Whatever, decided I wasn't fooling with it, well within return period. Fortunately I kept the original boxes. Initiated a return with AMAZON, easy peasy. Back it goes.

I’ve been using this for a while and overall it works pretty well. The pressure is good and it’s much easier than using a manual pump sprayer. I also like that it comes with different nozzles. The battery is probably the part I like the least. It works, but the battery life could definitely be better. I find myself wishing it lasted longer when I have more spraying to do. One other thing I noticed is a small leak where the spray wand connects. After I turn it off, sometimes a little liquid will still drip out from that connection. It’s not a huge problem, but it can get a little annoying. Other than that, it’s been working well and I’m happy with it. If they improve the battery and fix the small leaking issue, I think it would be a really solid product.

For the price I was shocked how well it worked. Mixed 4 gallons with moss out concentrate and went to work on my roof. It is heavy with all the water in it but the back pack was comfortable and rode fine. I used it and power was still at 90 percent. I could have filled up 10 times. I would run out of roof before it was close to dying. Highly recommend. Next is with round up for blackberry infestation.

I would buy this again.. I have back problems and with this I can spray my whole yard no problems. It’s comfortable holds a lot and works like a champ. I highly recommend.

This pack works better than I thought it would. I use it to spray my fruit trees, and it was very efficient at that. I like the on pack storage area for all of the tips that came with it. It also came with two different wands for different types of chemicals. I am impressed with the quality of the build and my only regret is that I wish I had bought it sooner.

El producto muy bn el transportista que es Fedex muy mala empresa para hacer los envíos llegó hasta otro día mi producto y no sikiera ala hora ..tampoco llego hasta mi casa muy mala compañía de reparto
