I am a believer in having as many USB-related devices, may it be to continue flow/oxygen supply for your tanks, when you need that pump to power up a miniature tank (if you are using it to medicate/quarantine fish).
But unlike other USB pumps, the Aquarium Air Pump, 3L/min Rechargeable Fish Aerator Pump offers one which is a rechargeable pump that has a built-in 2000 mAh rechargeable lithium battery and provides up to 8 hours oxygen supply working time and 36 hours lighting working time after a full recharge.
It’s easy to use, add a silver fountain on the top and you can hook it to your tank. and it also has a screw connection.
The pump has numerous functions, it has an intelligent mode (if you want to use it as a fauce), lighting mode if you need it like a flashlight but the primary mode is pumping/aeration in which the tube wil suck in the water and water comes out of the faucet.
You get two extensions, one for pumping mode and another with an airstone for aeration mode. Yes, you can use this for water changes on a nano tank. Put the tub with the pumping extension in your tank and the pump in a bucket and let it suck the water up and have it pour towards the bucket.
But if anything, the Aquarium Air Pump, 3L/min Rechargeable Fish Aerator Pump offers more than the basic USB pump, and the rechargeable battery makes it worth owning for emergency situations, especially if you have a power outage at home and you need to a pump to keep your aquariums oxygenated.
