VEVOR Battery Powered Backpack Sprayer, 0-90 PSI Adjustable Pressure, 4 Gallon Tank, Back Pack Sprayer with 8 Nozzles and 2 Wands, 12V 8Ah Battery, Wide Mouth Lid for Weeding, Spraying, Cleaning

Very satisfied with this sprayer. The pressure is strong and adjustable, and the battery easily lasts through a full tank. It’s much more convenient than a manual pump sprayer. The wide opening makes filling and cleaning easy. A solid product for the price.

I took a big chance on this sprayer as at the time of my purchase there wasn't any reviews. The quality of the build and accessories and large Lithium battery was the selling point. Initially the unit does not come with the straps installed and the instructions might as well have been in Greek. But looping a belt was not a hard thing for me, but might give others some trouble so I added a couple of pictures on how I looped mine. Over all I have used this sprayer for around a few weeks on and off. The battery lasts as long as your back can and more. Just don't leave the switch on and forget it for a few days unplugged. It will drain it. I stuck with the original brass tip and wand and it is both easy to hold and trigger for hours on end. I did have an initial issue with the gaskets but upon a good tightening, it has not leaked since. It has more than enough power to spray anything you would want to and enough accessories to fit almost any spraying needs. It is a 4 gallon sprayer, so keep in mind that it isn't going to be light when full. But the good part is that it keeps getting lighter as you keep spraying. The hose is top quality and will last for years. The wand is adjustable so if your tall or short, you will find the right length. The switch is fairly easy to reach when on your back and the dial for spray intensity is right next to it. The knob is in the accessory bag so keep that in mind when you first get it. I thought it was missing at first opening. The straps are easy on the shoulders and the ribbed back pad help keep the sweat down. The cross strap is absolutely essential in keeping this thing where it needs to be. Proper adjustment is going to depend on your size and height. The one thing I would have really liked to have is a wand holder on the straps. The one they put on the top is honestly pointless as the wand is taller than the sprayer. I fill this and put it on my table and simply strap it up at that level. Much easier than trying to do this from the floor. The large opening makes it easy to fill and the over all quality seems very good. They just need to fix the instruction book by someone who uses these things and attach the straps from the factory. It would save them from a lot of frustrated customers. I would definitely recommend this sprayer to anyone looking for a good quality sprayer in this size. Hopefully the price doesn't go to the moon.

I like the adjustable PSI, but seem to use it full on so not sure how much it matters. The pump works great and literally almost drains the container. The harness is so/so (not much padding and the cross belt is useless). This unit needs a stand badly and a handle as it tends to tip easily and there is no convenient way to grab it. Look, this weighs (with 4 gallons of liquid) around 60+lbs. It is a lot to have on your back so when you go to put it on full, make sure you have it sitting on an appropriately high counter/stool to ease into it. There are multiple spray heads (great idea) and even a manual pump to help unclog it. No way to tell how much liquid is left until you hear the pump go quiet which is OK i think. Large battery, not to be removed. Charges easily, volt meter is hokey and charging port could be better protected. Hose and spray wands (quality rubber with crimps and steel wands) very nice. Good unit could be great.

I have a steep yard and can’t use a tow behind sprayer for the yard. For the price this functions well and has a good battery life. Love the fact the battery is replaceable and a generic square battery.

I ordered this to simplify bi-weekly spraying of my lake house lawn and house. The Vevor 4 gallon sprayer arrived at a medium delivery pace but packaged well for safe transport. I own several Vevor products and like the value they provide for the decent quality of the equipment. This 4 gallon bug sprayer is unfortunately not one of those quality+value products. The sprayer was extremely simple to assemble (just screw an aluminum tube or plastic tube to the trigger handle and select a tip) and I found it straightforward to secure the straps to the sprayer backpack bottle. I tried texting for battery power immediately when I opened the package but did not see any LEDs indicating power. I assumed I possibly had to charge it so I let it charge overnight. The Vevor sprayer chargers with an included plug that has a single small LED indicating charging status. Red indicates “charging” and I assume that it either turns off or changes to green when fully charged, however, I will never know as mine did not charge. I tried the Sprayer the following morning and it still would not power on. I assumed it may be slightly an intelligent design and that I might need liquid in the sprayer to close a circuit, assuming that it auto shuts off so the pump doesn’t run dry. I filled it halfway up with water and again flipped the power switch, turned the dial all the way up, and tried again….still nothing. I inspected the battery to ensure the positive and negative terminals were securely attached to wiring, which I could see were secure and properly attached. The battery itself is rather large but extremely light in weight. It literally weighs similar to a fake demonstration battery I would MUCH rather prefer that Vevor utilized a Dewalt battery receptacle or any standard tool company battery which would make replacing batteries very simple. I would not recommend this to others based off my experience.

Vevor seems to be producing ALL kinds of products. Just check out their website; literally "anvils" to "zip lines". I may be getting lazy in my old age, but I got tired of pumping my sprayer when I was spraying for weeds in my lawn. I came across this sprayer when it was on sale (Vevor tends to run really good sales on their items at times). I have had great luck with this one. It comes with multiple attachment heads. The construction is primarily plastic, but it does not seem to be too thin. Motor is strong. Battery life is good. The five stars is for how well it worked out of the box. Concerns down the line: I hope the plastic holds up to use. I hope the plastic does not deteriorate due to chemicals. I hope the motor continues to work well. I hope the battery life continues to be strong. I have to figure out if there are any additional batteries I can buy for it. OVERALL: A good sprayer out of the box for price paid. I consider this to be a solid DIY backpack sprayer at a good price point. Not sure it would survive industrial use.

When you purchase you will find that it does leak and that’s because they forgot to tighten the fittings so make sure you tighten the fittings charge the battery fill it with your favorite juice and all you go

I have had this for about a month and used it to spray my yard 4-5 times to apply liquid fertilizer and bio stimulants. It's not perfect but more than sufficient to get the job done. What I like: 1. It's light. I'm in my early 50s and in average shape and find lugging this around with 2 gallons of mixture very doable. 3-4 gallons would probably be doable as well. 2. It doesn't leak. Use the teflon tape when you assemble it. The only time it leaked on me was when the hose connection to the tank had loosened after picking it up and putting it down many times. Just make sure you check that this connection is still tight before spraying anything nasty. Also, I probably under tightened it when I first assembled the product.. 3. It comes with lots of nozzels. 4. Has variable PSI range. Not just high or low. 5. Battery last a long time. I am able to spray my 13,000 square foot property with juice to spare. Things I don't like: 1. The red fan spray nozzle was heavy on the extreme left and right of the pattern so it wasn't really usable. I ended up replacing it with an XR Teejet 11004 VS nozzle. 2. The teejet nozzle did not fit in the provided elbow. I had to modify the elbow slight with a file or razor blade to make it fit. You can get additional elbows cheaply on amazon that come with a selection of cheap nozzles. Some of these will fit a the teejet without modification. 3. It would be nice if it came with a turbo flood jet style of nozzle for production that need to be watered into the lawn. I ended up buying the white teejet turbo flood jet nozzle for this purpose. 4. The hose connection to the tank can loosen over time. It would be nice if there were some way hold the end of the hose fixed to the tank so that it can not rotate over time. I might trying attaching a quick connect fitting at this point to remedy the issue. It's really not a big deal though. Just take that this connection is still tight every so often. 5. Not sure if the battery is really lithium. It looks very much like a generic lead acid. It's get the job done so whatever. I would recommend this product to a friend or neighbor. It's reasonably priced and gets the job done. Any struggles that I have had with it are largely due to my own inexperience with sprayers. If you are new to spraying then I recommend practicing with just water. Try out the various nozzles on your driveway or street to see how they cover.
