PULACO DC 5V USB Mini Submersible Water Pump with Tubing for Pet Fountain, Aquarium Fish Tank, Pond, Fountain, Hydroponics

this is a really good water pump for being USB. It can pump up to 50 gallons per hour. It’s worth your money. it has a small size also.

Well, I was flagged for saying I haven't used it yet but would be back when I do.I really don't know what more I can say. It's going to fit ourBirdbath 🐦. It's not very loud, and appears to be well made. I feel like I got my monies worth. Yes, it's still raining here. 🙄🌧😓💨💦

The pump, as some reviewers said, will deliver water only up to about 3 and no more than 4 inches high when I used a dedicated 3A USB charger. If I used a power bank, it will only provide up to 2-3 inches high. The power bank I was using was already a high power power bank.The operation of the pump, however, is very quiet. Although I hope to buy a more powerful pump as this is for pumping water through my cpap hose when under cleaning, it is not as powerful as I thought. Yet it would have been expected because it was USB powered. I don't want to buy an AC powered pump as it will be submerged in water and if anything happened, it may cause house breaker to trip, but using a power bank, it will not cause anything significant.All in all, for the price of the item, it is a good buy for me as it will work very well for my cpap hose cleaning.

This works much better than the pump that came with my catit fountain. Every time I go to clean, it's much less dirty than my last pump. If the water gets low, the pump is noisy but I've experienced that regardless of brand or money. I would buy again.UPDATE: the pump lasted approximately 4 months then gave out. So not long lasting at all

The adjustable flow of this pump is stupid and causes more trouble than its worth by vibrating out of place during use, I removed the slider from the unit so it would just run wide open. Really the worst part is that in only worked for 7 months in a cat water dish before it broke and no longer functions

The media could not be loaded. This is an impressive little pump. I use it to create a fountain in my birdbath. It has been in service continuously for a couple of years and has not failed yet. This includes many winter days when the birdbath water has frozen. The birdbath does have a heater, but that doesn't prevent the water from freezing on the coldest days. I pour a bit of hot water on the pump and it spings back to life. Using some stainless steel screening available elsewhere on Amazon, I built a small "cage" to extend the surface area of the inlet side of the pump. This extends the length time between cleaning.

The low speed is practically nothing but the high speed shoots water up about 2 inches up out of a plastic tube 1/2" ID 14 in long. My only complaint is the spout came off when I pulled the tube off and 2 suction cups came off the first time i used it.. The variable speed slide button is hard to slide. I am not sure it wasn't previously owned or used, the box was old I could tell.

Small pump but pushes out a good amount of water. I put one of these in my toilet tank on a smart timer so I can water my plants while I'm away on travel. It's quiet and so far, so good, it hasn't failed me after 3 months of regular use.
