How does it fire on its own?

There's a small electric pump inside. Hold the trigger and it fires a continuous burst of water, with a light at the muzzle and a shooting sound on every shot. There's even a little recoil kick. No pumping, no priming, no tired arm.

Size and range

It's about 19 cm long and 14.5 cm tall, so a compact one-hand pistol rather than a big two-hander. The ring at the back is the water tank. Real-world range is around 4 to 5 metres, which is far enough to soak someone before they see it coming.

Materials and build

Transparent ABS shell, so you can see the pump and internals working while you fire. The tank clips on with a twist lock and seals properly. CE marked.

Who it's for?

Anyone who's ever been handed a rubbish pump gun at a barbecue. The manufacturer rates it 14+, and honestly a lot of buyers are adults getting it for themselves. Younger kids can use it too with an adult around. Great for the garden, the beach and holidays.

Care and charging

The battery unclips from the gun and charges with the included USB cable. That cable has its own connector, so keep it somewhere safe. Empty the tank after playing and let it dry. It handles splashes fine but don't dunk it in the pool, the electronics aren't submersible.

Shipping & returns

Orders ship within 24–48 hours, with delivery in 7-8 business days. Not happy? Return it within 30 days for a refund.

I'm 19 and I have far too much fun soaking people at the beach with this. Buy it.

Fires fast and far, and the light is properly bright in the dark. Battery charges over USB. So much fun.

Got it for my 7-year-old grandson. My son tried it first and nearly didn't give it back.

You pull the trigger. It empties the tank.

An electric water pistol with auto-fire, light and sound. Pump guns are finished.

It's 30 degrees, everyone's melting on the patio, and someone's kid is waving a sad pump gun around. Then you walk out with this. Hold the trigger and it fires burst after burst on its own, muzzle flashing, shooting sound going, little recoil kick in your hand. The whole garden picks a side within about ten seconds.

Frequently asked questions

Yes. There's an electric pump inside, so holding the trigger fires a continuous burst until you release it. No pumping at any point.

Around 4 to 5 metres in real use. Some listings for guns like this claim 10 metres; ours doesn't, because that's not what you'll get in your garden.

The battery unclips from the gun and connects to the USB cable in the box. A charge is enough for a good session of water fights. One tip from buyers: the cable connector is specific to this battery, so don't lose it.

The manufacturer rates it 14+, and plenty of parents buy it for younger children to use with supervision. Never aim at the face or eyes, and keep it away from children under 3 as it contains small parts.

It's built to get splashed, that's the whole point. It's not submersible though, so don't dunk it in the pool or the sea. Empty the tank after use and let it dry.
