What is a 12-Volt Aquarium Air Pump and Why You May Need It

As the name implies, a 12-volt aquarium air pump runs power from low-voltage sources, such as car batteries (cigarette lighters) or 12-volt storage batteries. Also, you can connect the pump to a standard 220-volt outlet via a special transformer.

The sphere of application of 12-volt pumps is quite broad. Primarily, they are used as a backup option, for example, in the case of a power outage. Additionally, a low-voltage pump can be of use when you need to transport a fish aquarium by car. Finally, it can serve as a tool for outdoor pond aeration; you may use it when fishing for keeping live fish, in fish restaurants, and so on.

Best 12-Volt Aquarium Air Pumps: Our Choice

The assortment of 12-volt air pumps in the market is limited if compared to the 220-volt options. However, some brands offer decent solutions of this type. Here are top-five models of 12-volt pumps, which, in our opinion, are worthy of considering.

biOrb 46037.0 Air Pump 12 V Aquariums

biOrb 46037.0 Air Pump 12 V Aquariums

This aquarium air pump is small, lightweight, and affordable. It has a single air output for attaching a hose and four rubber legs that are supposed to minimize the vibration. The device is AC-powered, which means you need a 12-volt plug or a special transformer to connect it to your home line. At the same time, it can’t be plugged directly into a car charger or a storage charger. Thus, it is not really a backup option.

What we think

Probably, the largest drawback of the device is being AC-powered. Generally speaking, it can’t replace your regular aquarium pump in the case of a power outage. Also, you can’t use it in a car without a transformer. Otherwise, it is a good entry-level option for those having 12-volt wall warts.

PROS

  • compact and lightweight;
  • very affordable;
  • easy to use;

CONS

  • AC-powered;
  • relatively noisy.
Yosoo Aquarium Air Pump

Yosoo Aquarium Air Pump

It can work from any 12-volt power source, including car batteries, solar panels, and so on, which makes it a great backup option. You may also use it for live fish transporting, aquaculture, and outdoor pond aerating. Thanks to a convenient handle, it is easy to move around.

What we think

Portability and convenience are the strong points of this Yosoo air pump. Its sphere of application is not limited by aquarium aeration. That said, it tends to be a bit noisy when used indoors.

PROS

  • compatible with any 12-volt power source;
  • portable and versatile;
  • DC-powered;
  • a good flow rate.

DC 12V 80Lpm/Min 60W Aquarium Air Pump

If you need a durable and reliable portable air pump, consider this multi-purpose DC 12-volt pump. It is driven with a powerful permanent magnet DC motor, which provides an impressive capacity of 80 liters per minute. The device is small and lightweight, while its direct-drive motor is quiet, efficient, and reliable. The pump can be connected to any DC power source.

What we think

While being a bit pricier than its counterparts, this heavy-duty pump is definitely worthy of consideration. It does its job well and, according to customer reviews, lasts long. This is a kind of pump that combines high efficiency, portability, and versatility.

PROS

  • DC-powered;
  • works from all types of power sources;

Another entry-level option by biOrb is a 12-volt AC-powered pump for safe aquarium aeration. It features a single air output and comes with no extra accessories. It is very easy to use, small, and lightweight. But you’ll need a special transformer to plug it in. Unlike DC-powered units, this one can’t be powered by a car charger or a storage charger.

What we think

The main problem of all AC-powered devices is their limited sphere of application. And still, this mini-pump can turn useful if you have a reliable 12-volt source of power. It is safer and more economical than traditional 220-volt options.

  • affordable and economical;

Frequently Asked Questions

12-volt aquarium air pumps are quite easy to use. However, if you’ve never used them before, check the answers to some popular customers’ questions before plugging-in a new pump. We hope this section will be useful to you.

Q: 12-Volt Aquarium Air Pumps: How to Use?

A: Attach the tubing to the air outlet of the pump on the one end and to an air stone on the other end. Place the air stone into your aquarium. Make sure the pump is placed above the water level or use check valves to prevent water from getting inside the device. Then plug in the pump.

Q: How Does an Aquarium Air Pump 12 Volt Work?

A: 12-volt pumps are powered by low-voltage power sources, such as car chargers, storage chargers or solar panels. They use a vibrating membrane or a piston to infuse air into the water, creating numerous tiny bubbles. These bubbles rise to the water surface, mixing it up and aerating.

Q: How to Set up a 12-Volt Air Pump?

A: Commonly, 12-volt pumps require minimum set up. Various models can have or not have the features of adjusting the air flow and choosing between one or two air outlets. Usually, all you need to do is just to attach the tubing and air-diffusing devices and plug in the pump.

Q: How to Make an Aquarium Air Pump Quieter?

A: If the vibration produced by your pump seems to be too annoying, use a simple DIY solution. Take a towel or another thick soft cloth and place the bump on it. It will act as a damper and reduce the noise.
