Submersible Water Pump, 200L/H USB Water Pump for Aquarium, Fish Tank, Statuary and Hydroponics DC 3.5-9V 1-3W(0.4-1.5m) #1 Black/Side Suction Cup

An excellent, USB powered pump, bought to create my own water feature, that would work when there was no sun to power my solar powered water feature. Quiet, it generates enough power to create a small fountain in an oval ceramic dish, i've filled with water & small pebbles. Very attractive & relaxing. Cable is a good length, & simply place pump below water level & you have your own water feature.

Bought two of these to improve the flow and spread of CO2 across the middle of my 288 litre planted aquarium. These pumps are TINY! Which worked out great because they’re not as noticeable. Seem good quality and stick to the glass very well. There’s 5 different flow strengths, the fifth (max) setting is surprisingly strong. The flow adjustment slider is a little bit of a pain because it slips and doesn’t always change the flow to the one you want. But, once you’ve selected and got the flow you want, it’s not really a big deal. They’re also a little noisy, but not to the point of annoyance. Both pumps are still working very well and have done the job I bought them to do.

great powerful little pump, had it outside in a water feature and has not failed after a 3 plus years of almost constant use and being exposed to harsh winter conditions. Ended up buying another recently for extra filtration in pond

Excellent replacement for cat water fountain and stronger than the original too. Really pleased. I’ve found it to be quiet in operation, not totally silent but it’s in my kitchen and you can’t hear it unless you get really close. I mention this as I nearly didn’t buy because of some reviews around noise.

Really pleased with this item. Easy to use, good quality, and arrived on time. Would definitely recommend.

The size of this is surprising, I know the measurements are available but I hadn't really visualised how small this is. Despite this it is running quite happily in our water feature and produces a steady flow when connected to a standard 5v USB outlet on a power-bank. I have since purchased a solar panel and a 12v to usb adapter and it runs at variable speeds depending on the level of sunlight available. Curiously it is rated from 3-9v despite the USB connection so it should be possible to wire a USB socket to a higher-voltage source and increase the flow rate. It has a simple flow-rate adjuster but we have left it wide open to get the maximum flow rate from our variable power source, the base has two small suction cups which might come in handy depending on your application, the only useful addition would be an intake filter of some sort but for the price it's a great buy. The cable is a meter-or-so long so enough to get out of most small water features or aquariums and the overall finish is good.

UPDATED REVIEW: DO NOT WASTE YOUR MONEY ON THIS PRODUCT! I originally rated this product 2 star with the below review however after less than a month of use: - the suction cups have zero so too left so I’m having to reposition the pump multiple times a day - the power of the pump (which wasn’t great to start with) is now virtually non existent - despite the loss of function of the pump it’s STILL louder than any previous pump I’ve had It’s at the point that I have no choice but to buy a replacement pump - that shouldn’t be the case after less than a month. Once again… do not waste your money on this piece of useless junk! _________________________ Original review: I bought this as some of the other reviews mentioned it being an adequate replacement for their pets drinking fountains. I wish I had ignored these reviews and listened to the ones that complained about noise levels! Sure it fit, was easy to install and the suction cups worked well...but everything after installing has been a negative experience! It looks exactly like the the original pump in terms of size, shape etc. so I can’t see why it would have such inadequate performance in comparison BUT it’s barely powerful enough to actually make the fountain function, and it’s so ridiculously and needlessly noisy - I could maybe understand the racket if it was powerful, but it’s really not, I swear I could make a better fountain spurting the water from my own mouth! It gets the job done, kind of (which I why I gave it 2 stars not 1) but for me it’s absolutely not worth the actual headache to have to sit and listen to the damn thing all day. I would not recommend this product.

Compact, quiet, and efficient little pump. Perfect for small aquariums and hydroponics. Suction cups could be stronger, but overall great value.
