I cannot speak for how it will fit on a water cooler bottle, but this works well for my needs. I collect tap water in gallon jugs. I leave them be for a few days so that the chlorine evaporates. Then I water my plants with this water. Pouring directly from the jug causes splashes and puddles. I couldn't find a watering jug I especially liked. Instead, I got myself this water cooler pump. I charge it the pump using the included cable. Then I stick it on top of the gallon. I press the button and I have a fancy watering can. Beware, this thing is loud. Not a problem for me though.

Exactly as advertised. Extremely pleased with the product. Exceeds our expectations. Came very quickly and we will likely buy a couple more. We are on a well with very hard water so use bottled water for drinking and cooking. We have a water dispensing unit in our kitchen and bottled water in other areas of our home. Much superior to the manual pumps they sell in Camping good stores that we were currently using. And a similar price point.

a little noisy.
