Lithium ion products take 2-3 weeks to arrive. They will be shipped separate from the rest of your order.

The air pump you've always needed is here. Keep your aquarium water well-oxygenated and your fish healthy in absolutely any scenario — even when the power is out. The Aquarium Co-Op air pump utilizes a rechargeable lithium-ion battery and can be run continuously for up to 8 hours on a charge. The included power cord is over 11 feet long, allowing you more flexibility on placement. It can be plugged into a wall outlet like a standard air pump or powered using an external USB battery bank for portable use.

This truly essential piece of equipment can provide you peace of mind that your aquarium is safe even in an emergency because the air pump automatically switches to battery use if it loses power. The air pump operates reliably and quietly in two modes: continuous mode and power save mode (where the air cycles between 15 seconds on and 15 seconds off to conserve battery).

Excellent product

Love the batter backup.

Quiet, adjustable, amazing!!

I *love* the features of this air pump— it's the only air pump you'll need! First off, it's soooo quiet. I'm pretty sensitive to sound, and I only hear it when I put my head right next to it. Second, it works while plugged in or running on battery, and automatically switches to battery in a power outage or if it accidentally gets unplugged! You get five levels of air flow power, so you can freely switch air pumps around your setup or it can grow with you if you decided to get a bigger tank. Like I said, the only air pump you'll need.

I had first gotten a PetStore battery-operated backup pump and goodness was that thing was loud. So I started shopping around for air pumps that were quiet but could also automatically switch on in a power outage (because of course prior to fishkeeping, I never lost power but then this summer my power went out multiple times). Aquarium Co-op's pump saves you hassle and money of having to get battery backup plus a normal pump because it does both automatically!

I only have nano tanks currently, so I just use the lowest air flow setting. But the fact that each pump has five levels of power makes it simpler for everyone since it's universal. You can use this on a 75 gallon then switch it around and put it on the lowest setting for a 5 or 10 gallon, or a hospital tank. Genius.

Amazing pump!

Quiet, adjustable, powerful. Perfect pump, and now I don’t have to worry if the power goes out.

The best!

I bought one of these it works far better and stronger than ANY other and far less noise! And it is much smaller. I really love the one I got and am trying to get more to replace a certain 60 gal one on a 10 gal tank that is suppised to be quiet but is so load it drives me crazy!!

Good pump

Works great no issues, having a battery backup is a great feature, I have the single output one also, the duel output one is a bit louder which is to be expected with a bigger pump but not unbearable, overall good, we will be back for more products from you guys
