Review on 💧 Electric Drinking Water Pump Portable Water Dispenser, Universal USB Charging Water Bottle Pump for 2-5 Gallon, with 2 Silicone Tubes - 5 Gallon Water Dispenser by Joshua Wheeler

This little pump works very well. I'm on my fifth bottle on my first load. I recently got rid of my water cooler and decided to just use room temperature water with a nice wooden bottle holder. This pump meets all the requirements, it is very convenient to use, and the charge lasts a long time. The only downside is that it doesn't have a universal fit for water bottles. I have standard 5 liter bottles from a major supplier, but the pump is too big to fit the neck of the bottle and too narrow to fit over the plastic cap. My solution was to trim one of the plastic caps down to about 60% of its circumference, which now fits perfectly, see photo. An adjustable neck solution would be better.
