4.9Ah Battery Powered Backpack Sprayer 4 Gallon, Doubled The Capacitance, Equipped with a Big Pump, Ultra-Long Power Supply Lithium Battery Waterproof Sprayer for Spraying, Cleaning

Purchased this sprayer specifically to spray liquid aeration product on my lawn and garden. The unit was easy to put together. Just attach the wand holder with the four screws, and connect the wand to the handle. Charge the battery and you are good to go. The wide mouth on the sprayer made it easy to fill without spilling. The spray is easily adjusted with two set tips and one adjustable tip. The 4 gallon capacity makes the sprayer a little heavy, but once I placed the sprayer on a table, it was easy to put on. The sprayer was comfortable and worked well. I only used the 35 psi setting for my lawn, but tested the 65 psi and know that it can handle spraying trees. I had no leakage from the sprayer, and in all, the sprayer worked great. It was a good investment and time saver as I was able to complete my spraying job in about half the time it normally takes. I do have one tip: Be careful mixing whatever you are going to use and minimize the foam going into the sprayer. It is difficult to get out and lessens the amount of liquid that can go into the sprayer without causing a foamy mess.

had a problem with this unit. ran very well then failed after a littler over a year. I contacted the company and they took very good care of me and got me up and running . excellent customer service.. highly recommended.

This thing worked great for about three weeks, diddnt spray as far as advertised but that’s ok. Today, it just quit working altogether..and I’m past the return window, don’t buy this thing if you are going to be using it every day.

Bought this sprayer to do pest control treatments. Previously used a Flowzone sprayer but purchased this one since it was cheaper. It's functional and everything. My only dislike is the fan pattern it puts out. When spraying a foundation the pattern is heavy at the top and the bottom, while light in the middle. This causes me to go over the same spot several times to get even coverage. I didn't have that issue using a Flowzone. If the tip could produce a solid even band of liquid I would've gave it 5 stars.

The media could not be loaded. These ALIENTABI backpack comes with an 18V battery, 3 different nozzles, you can change the pressure from 65 psi or 95 psi just with a flip of the switch.Plus it makes even spot spraying the yard for dandelions an easier task. I compared this sprayer to my old 4 gallon backpack sprayer which was a pump type which wore me out way before finishing spraying, the shoulder straps on it are thicker and padded, so you really don’t feel the weight. With this sprayer, it’s ambidextrous. You can use either your right hand or your left hand to spray, as compared to my old one where you always had to pump with the left hand and spray with the right. Very tiring process with my old sprayer.I measured the longest distance that I could get with a full battery and the adjustable sprayer nozzle, you can spray up to 33 feet. Perfect for spraying those poison ivy vines that grow up the sides of our fence.On the video I used it to spray the flowers we have with water, also the flower beds where we are growing vegetables and peppermint, it’s excellent also if you don’t have a faucet near to put a hose, this makes it very easy, you can also use it to clean windows or my husband used it to clean the metal on the garage that he’s going to paint in one color. But I mostly bought it to fumigate my backyard this summer for fleas from the neighborhood straight cats and also for mosquitoes which during summer are bad.Overall this backpack sprayer is the best thing since sliced bread, and it turned my four or five times yearly back breaking chore into a quick, easy task. Versatile many ways to use it. 100% recommended.

I purchased this specifically after it was referred to me by a professional pest control technician. It is high-quality and worth the money. It works very well.

I currently own a few sprayers and I must say, this is by far the best sprayer of them all. When I took it out of the box I immediately noticed how well designed it was. The battery has an indicator of how much charge it holds which is super useful. The compartment where the battery is placed is water proofed with a rubber seal around the door which I think the little door will take force to break loose so opening and closing it numerous times won't affect it anytime soon.The battery life seems to be really good. I haven't had the sprayer for a long time, but I used it 3 times so far to spray 3,000 square feet of lawn and it still has plenty of charge so thats a win for me. I wanted a lithium ion but form factors are all unique to vendor. I use SAMSUNG and got to thinking that a charger/battery system is to expensive and the industry standard sealed lead acid battery can be purchased anywhere for cheap. The heaviest portion of the sprayer is the product and the slight extra weight of the battery is insignificant compared to the product. Long term cost wins and these batteries are proven performers.So, this is a really nice sprayer, but what about it's capability of spraying liquids? As I mentioned before, I own a few sprayers and this blows them out of the water! The stream can easily reach the top of my two story house from ground level. It is capable of putting down liquid lawn fertilizer with ease and faster. I like how far the wand extends which also comes in handy if you're spraying chemicals, keeping the mist spray as far away from you.Overall, I love this backpack sprayer. I don't think there's anything negative about it. It's well built and looks like they put lots of effort in the design. I definitely recommend it!

battery life is great. this saves me time and money when I don't have to fire up the hundred gallon nursery sprayer to solve a plant problem. 40 years experience in the nursery landscape trade
