What to Consider When Choosing the Best Electric Water Gun

Before deciding on the best electric water gun for your needs, consider a few important product features. The following section looks at some of the most essential considerations to help you find the best power-packed water gun for your needs.

Intended Use

Water guns are used both indoors and outdoors, so the type of use will have a big impact when choosing the right model. If its an all-purpose tool that will see a lot of movement, then choose a rugged, durable model that can take a bit of a hammering. However, if its a more delicate instrument, go for something lightweight with no exposed metal parts.

Its also worth checking what kind of voltage the unit requires. While most models can run off a standard 110/120-volt household outlet, there are options that require 220/240-volt outlets or even a direct connection to a generator.

Power Source

The majority of water guns now come as cordless tools, but they’re still available in corded models. The latter provide a constant source of power without having to worry about recharging times, though they do need a designated outlet.

There are two main types of power for corded water guns: gas (also called fuel) powered and battery powered. Older models often use a mix of gas and battery power, which is fine as long as the ratio remains the same. More recently, however, manufacturers have started using only battery power.

Gas-powered water guns have a separate tank of pressurized gas that powers the pump through a valve. Battery-powered water guns rely on a rechargeable battery to power the pump. Although there are variations among products, most batteries should be able to run for between 30 minutes and 60 minutes before needing a recharge.

Flow Rate

A water flow rate indicates how much water per minute the pump can push out. It is usually given in gallons per minute (GPM), although some manufacturers may use liters per minute (LPM). In general, the higher the GPM, the better the flow, though it depends on the size of the hose and the amount of pressure required.

For those who want a high-pressure shower, a unit with a higher GPM is necessary. For those who want to fill up a watering can, a lower GPM is sufficient. Most units have adjustable flow rates, so its easy to switch from a low-pressure shower to a high-pressure rinse.

Hose Length

As mentioned above, the length of the hose has a big impact on the pressure produced. Longer hoses mean less resistance, and thus a greater pressure.

While longer hoses generally means better performance, there are limits. At some point, the increased friction will slow down the flow. Its a balancing act between length, diameter, and pump power.


The hose attachment (diameter) will have a significant effect on the water pressure delivered. Standard hose attachments are inch, inch, and inch. Again, the larger the diameter, the easier the water flows. These sizes arent just about right, they’re also the most common, so its a simple task to find a replacement fitting.

However, there are variations. Some manufacturers may include a slightly smaller diameter fitting than the one supplied. This may be due to a desire to keep the hose as short as possible, or it could be because the company found the existing fitting was inadequate during testing.


Electric water guns dont generate any steam, so the weight of the water heater isnt relevant. However, the weight of the pump itself may be important. As well as determining whether the unit is too heavy to lift, its also vital for ensuring the pump is properly attached to the water hose.

Most pumps are fairly robust, but its important to check the fixing method. Screws are common, but especially in older models, bolts may be used. Older models may also have a handle that must be lifted to turn the pump off.

Ease of Use

Given that these tools are designed to make water spray, the ability to quickly attach and detach the hose and adjust the water flow are critical elements. Quick-connect fittings and levers that lock in place help here.

Another aspect that can affect ease of use is the shape of the hand grip. A pistol grip is common on gas-powered water guns, but there are models with a more traditional-style top handle that may be easier to use.
