Overview
Cosori 1.7-liter glass electric kettle with a 1500W element and no plastic touching the water, aimed at households that want a larger-capacity kettle with a visible water level and quick boil times.
The borosilicate glass body and blue LED add a visual element other kettles skip, letting you watch the water heat. At 1.7 liters it holds noticeably more than compact 1-liter kettles, useful for multiple mugs of tea or coffee at once. The shutoff runs on a mechanical steam-powered system rather than electronic sensing, an older, simpler design that still works reliably by reviewer accounts.
- Borosilicate glass body
- Mechanical steam-powered auto shut-off
- Boil-dry safety protection
- Cool-touch handle with precision spout
Who it's for
Suits households making tea or coffee for more than one person at a time, and anyone who prefers glass over stainless for seeing water clarity and level. Hard-water households should expect more frequent descaling since mineral spots show up faster on glass.
What buyers say
From Amazon customer reviews.
Several reviewers highlight the lack of plastic contact with water and describe the boil as fast, generally under five minutes for a full kettle. One reviewer's start button failed after about five months, and Cosori replaced the unit under warranty once a video of the issue was submitted. Another flagged that the lid mechanism feels stiff and that hard water leaves mineral spots on the glass faster than expected.
