4 Gallon Backpack Sprayer with Powerful Battery Pump - 15L Orange Garden & Lawn Sprayer for Agriculture, Weed Control, Pest Spraying - Ideal for Large Yards, Farms & Commercial Use

I like the sprayer, however I lost the charger for it and can find nothing to help replace itA great sprayer when it worked. But the battery has stop taking a charge, so I have a very pretty orange lawn decoration.I liked the performance of this sprayer but initially gave it only 4 Stars because the spray-wand began leaking on the second use (not out of the "ends" of the wand, but the wand shaft itself starting leaking the liquid content when power was turned on.HOWEVER, I contacted the company through Amazon and they immediately sent me a brand new wand no charge. So I am now upgrading them to 5 Stars._________________Handy Tip: When filled to the full 4 gallons, the Tank was too heavy for me to carry comfortably on my back. I tried it once and ended up with a very sore back.So...the next time I used it to the full 4-gallon capacity, I sat it on the floor of my riding lawnmower between my legs and did my whole yard effortlessly (left the blade turned off, of course). Additionally, this allowed me to set a constant speed on my lawnmower, so it didn't have to watch my pace as I did when I used it walking.Just thought I would pass this along.First the good: this the tank holds a lot of liquid and has a screen to filter out any dirt that might get bumped into the opening when you fill it. I had a lot of power too. I can spray 20 - 30 feet or more if I take the limiter out of the nozzle.The bad: this beast is heavy, and that's before filling it. And something annoying is that the pump motor runs constantly once turned on, unlike my 2 gallon Scott's which only runs the motor periodically.So my major problem with this unit is the weight. It is so heavy. I don't know if they need a huge battery because it runs constantly or if they use a less efficient battery technology than the Scott's. But the Scott's battery is as big as my fist vs the battery on this unit is as big as a riding mower battery or more.So I will continue my search for a large capacity battery powered sprayer.The clips that attach the carrying straps to the bottom of the sprayer continually fall off. It needs a better system of attaching the straps. Otherwise, it was working fine until the pump quit. I would like to return it.Works very well. Has several different nozzles for various spray patterns. Appears to be a very solidly constructed and suited for various projects. The only question would be the charger and associated wire and connector may be a little fragile.This sprayer sprays really well. Because of the high pressure there is a lot of misting. This is great for most applications but for weed killer may not be wanted. For my use killing poison ivy I wanted a long and high reach and spot application so had to remove a small white baffle inside the angled nozzle so works great!Almost 5 gal capacity combined with the weight of the empty sprayer makes a lot of weight to carry.It is well made and I just ordered a second one for insecticide.For someone trying to decide between a Hudson and this sprayer, buy this one and save your money! It is the same sprayer with a different color tank (orange vs yellow). I own both and they are identical inside since I've torn both apart, the Hudson to make a repair I caused and the Beaugreen to make a change to hopefully prevent the same break I caused in the Hudson.
