Pawfly Aquarium Air Pump 2.5 L/min Battery Powered Oxygen Pump for 20-120 L Fish Tanks, Portable Silent Aerator Pump with Metal Back Clip for Outdoor Fishing Power Outage (D Battery not Included)

This is value for money. A bit noisy but I still like it

The title would lead you to think it was a self contained unit but it’s not. I run mine on rechargeable NiMH 10000 mAh batteries. They last at least two and a half days on a full charge. I little more noisy than advertised but not overly intrusive. On the whole a good buy for emergency use at home or travel where you need aeration.

Does the job perfectly

Great little product! Purchased for our little goldfish pond. Came the day after ordering, well packaged and simple set up. When you take it out of the box, everything you need is located in the battery compartment - Nice thick but malleable air pipe and a little air stone. The air stone produces loads of little bubbles and my two little fish seems to enjoy it. Not silent but not really loud. Really good value for money. So far I've ordered two - Will be ordering again. Highly recommend.

Not silent at all don’t expect to have this in your bedroom tank it’s soo loud and definitely not silent at all it has good power to it with the air flow but It is very loud

Very useful, always i can use for emergency situations also.

This battery pump is made of better materials than I was expecting. Like it says in the description, an ideal back up solution for tanks when there is no mains power. Has a clip to the back which can be removed, but no rubber feet - hence the description saying something to the effect of put it on a mat...

Excellent value for money. Works perfectly.

Worked great for a cross country move, kept my shrimp happy with a working air stone for the drive. Used my wall powered one at night in the hotels, ran this during the day. Only had to change the batteries once in 3 days. A little noisy but not bad, just threw a towel over it to muffle it a bit.

Exactly what I needed and has saved me from a few power outages

Works as described

I used this product for my mad scientist halloween display. It was worth the money and did it's purpose. After halloween I placed it in ma aquarium where I run it a couple of minutes every other day. It's sturdy, durable, easy to use. Battery lasts long enough, it's pretty quiet with pretty decent airflow.

This was amazing! I bought this to move my 4 fish from Oklahoma to Texas, a 10+ hour drive. I popped the fish in a cooler and placed this in there with them. It worked! It kept them alive. I even used it for about another month before I could get an actual tank set up for them. I highly recommend this. The only downside is you will go through batteries, so make sure you stock up if you plan to use this in an emergency or for moving.
