Best 4 Aquarium Battery Backups When Power Goes [2024 Updated]

 What is Aquarium Battery Backup?

Air pumps and powerheads in the aquarium require a steady supply of electricity. However, it can be challenging if you live in an area prone to power outages, blackouts, or rolling brownouts. Thankfully, there are aquarium battery backups available that can provide 24*7 electricity to the fish tank, ensuring the water stays oxygenated.

Jackery Explorer Portable Power Stations come in different sizes and capacities, making them ideal for all sizes of fish tanks. They are built with highly efficient and durable LiFePO4 or NMC batteries, along with leading battery management technology. These aquarium battery backups can provide hours of electricity to all the electrical appliances in the fish tank.

What Happens In Aquarium When Power Goes?

When a power outage happens, the filtration and pumps in the aquarium stop working. This, in turn, leads to the temperature drop based on the surrounding climate. The lack of oxygen in the aquarium can cause fish to die within 1-2 hours. Some of the key concerns of power failure include:

• Oxygen can be consumed within a few hours, and if it is not resupplied, the fish will start dying.
• The ability of aquariums to manage the ammonia decreases due to the lack of oxygen.
• The temperature in the fish tank will start fluctuating when power goes out.

How Does Battery Backup for Aquariums Work?

Jackery Solar Generators for aquariums combine Jackery Explorer Portable Power Stations and Jackery SolarSaga Solar Panels to charge appliances. When the sun's rays fall on the Jackery SolarSaga Solar Panels, the high-quality monocrystalline silicon solar cells of the solar panels convert more sunlight into DC electricity.

Then, it is supplied to the Jackery Explorer Portable Power Stations, where the pure sine wave inverter converts DC to AC electricity. Jackery Explorer Portable Power Stations can also be recharged using a car charger or wall outlet, so you never have to worry about power failure.

How Much Electricity Does An Aquarium Use?

On average, the aquarium uses nearly 63 watts of electricity. However, the exact watt consumption will depend on the size, brand, and electrical appliances used in the fish tank. Here's a table that reveals the watt consumption of an aquarium based on its size and capacity.

How to Choose the Best Battery Backup for Aquarium?

There's no doubt that battery backups can keep all the fish tank appliances when a power outage occurs. However, you'll need to choose the aquarium battery backup that meets the wattage needs of the appliances. Here are some factors to consider before selecting the best battery backup for aquariums.

Capacity: First, you'll need to check and add the running wattage of the fish tank appliances, including powerheads, filters, and heaters. The battery capacity of the power station should be higher than what you require for the aquarium.

Lifespan: Compared to lead-acid batteries, NMC lithium-ion or LiFePO4 has a long lifespan of up to 10 years. Jackery Explorer Portable Power Stations feature NMC lithium-ion or LiFePO4 batteries that are best known for durability.

Safe to Use Indoors: Unlike gas generators, the battery backups do not emit noise or toxic fumes. Hence, they are safe to use indoors.

Maintenance: Choose the aquarium battery backup that's easy to use, install, and keep in storage. For example, Jackery Solar Generators are easy to set up and operate. Just plug the appliances into the multiple output ports and start charging.

Size: The choice of battery backup for aquariums depends on how easily it can be moved from one place to another. It should be light in weight, portable, and feature an easy-to-carry handle for easy transportation.

Quiet: Battery-powered generators do not have any moving parts, and that's why they are quiet. While choosing the battery backup for the aquarium, ensure it emits only 30dB to 45dB of noise.

Aquarium Battery Backup FAQs
