What is the hottest I can get a beverage with the Cooper Cooler?
The hottest you can get a beverage is the temperature of the re-circulating water you add. Don’t add boiling water. Use hot tap water. Adding water any hotter than 140°F/60Cand the Cooper Cooler might be deformed. If you are using the Cooper Cooler to warm a baby bottle, the milk or formula will never be hotter than the water you add to the unit.
