While it isn’t the most popular option, we still have some 2-gallon hand pump sprayers in our review section. They are only slightly more expensive than the most common 1-gallon type, offer more volume but they are still fairly easy to carry when full. Here they are:
Premium: A bit more pricey but a quality sprayer that also offers several useful features like the pressure relief valve or 5 nozzles.
Good 
Basic: Cheaper and very easy to use, on the other hand users describe the pump and wand as lower quality and a bit fragile.
