Performance and Speed
The Cosori Original Electric Glass Kettle demonstrated solid performance in boiling tests, achieving a 1.5-liter capacity boil time of 6 minutes and 42 seconds, which aligns with its advertised British STRIX Tech claiming times between 3 to 7 minutes. Shouldit.com rated this performance at 9.3/10, noting it matched other 1500W kettles in speed. The kettle's 1370W power draw consumed 151Wh to reach boiling point, scoring 7.8/10 for energy efficiency according to the same review. However, TechRadar's testing showed it was slower than the Fellow Stagg EKG, which boiled the same volume in 4 minutes and 25 seconds, indicating the Cosori's heating element could be more efficient. The kettle's performance was consistently praised for its quiet operation, with a peak noise level of 66.3 dB during boiling, which is well below the CDC's recommended 80 dB exposure limit for 2 hours, earning a 9.4/10 rating for noise level from Shouldit.com.
Design and Build Quality
The Cosori Electric Kettle features a distinctive design with a borosilicate glass carafe, stainless steel under-lid, and a V-shaped spout that's integrated into the glass itself, ensuring no contact between hot water and plastic. The kettle's dimensions are 9.1 x 6.2 x 10.3 inches, weighing 2.4 lbs, making it compact yet substantial. The black matte finish with blue LED ring and removable mesh filter contribute to its aesthetic appeal. The kettle includes a pop-up lid and a large opening of 4.3 inches, which facilitates easy filling and cleaning. However, The Spruce Eats noted that the exterior gets very hot during use, a downside of the 100% stainless steel construction, and the kettle lacks insulation, making it difficult to handle without a protective glove. The base includes a cord storage area, a non-slip handle, and a thumb rest, enhancing usability and safety. The kettle's build quality was rated 7.0/10 for the carafe, 7.0/10 for the handle, and 8.0/10 for the base by Shouldit.com.
What Reviewers Loved
Reviewers consistently praised the Cosori Electric Kettle's quiet operation, with Shouldit.com noting a peak noise level of 66.3 dB, significantly quieter than typical kettles. The lack of plastic contact with water was a major selling point, as highlighted by Shouldit.com's review, which emphasized the stainless steel under-lid and glass construction for pure taste and safety. The kettle's fast boiling time of 6 minutes and 42 seconds was also appreciated, scoring 9.3/10. The large opening and wide mouth design were noted as excellent for cleaning and filling, with a 4.3-inch diameter opening that allows easy access. Additionally, the blue LED ring that illuminates during operation was seen as both functional and aesthetically pleasing, contributing to a modern look. The Spruce Eats reviewer particularly liked the five temperature presets for tea and coffee, with each button corresponding to a specific ideal temperature, making it easy to use and intuitive.
Where It Falls Short
Despite its many strengths, the Cosori Electric Kettle has several drawbacks that reviewers noted. The primary issue was its average heat retention, with a temperature drop from 212°F to 201°F after 5 minutes, scoring only 6.5/10 for keep warm functionality, according to Shouldit.com. The kettle also lacks a temperature control feature or a keep warm function, which is a significant limitation for users who need to maintain water temperature. Additionally, the kettle's low water capacity of 1.7 liters (57.48 fl. oz) was criticized by The Spruce Eats, who noted it was only suitable for small households. The exterior gets very hot during use, a downside of the 100% stainless steel construction, and the kettle lacks insulation, making it difficult to handle without a protective glove. The gooseneck spout, while aesthetically pleasing, was deemed difficult to control the speed of water flow, particularly for pour-over coffee, according to The Spruce Eats, who found it less than ideal for this purpose despite its benefits for tea.
Who It's Best For
The Cosori Electric Kettle is best suited for individuals or small households that prioritize quiet operation, safety, and aesthetic design. It's particularly appealing to tea enthusiasts who appreciate the five temperature presets and the precision spout, as noted by The Spruce Eats. The kettle's lack of plastic contact with water makes it ideal for those concerned about purity and taste. However, it's not recommended for heavy coffee drinkers who rely on pour-over methods, as the gooseneck spout doesn't offer the precise control needed for consistent pour-over brewing. The kettle is also not ideal for those who need a large capacity or a keep warm function, as it lacks both features. The Cosori Electric Kettle is a solid choice for those seeking a reliable, quiet, and stylish kettle with a focus on safety and ease of use, but it may not meet the needs of users requiring advanced features or large capacity.
How It Compares to Alternatives
When compared to the Fellow Stagg EKG, the Cosori Electric Kettle falls short in boiling speed, with the Fellow model completing the same task in 4 minutes and 25 seconds, according to TechRadar's testing. The Fellow EKG also offers superior temperature control and a more precise pour, making it a better choice for pour-over coffee enthusiasts. However, the Cosori Electric Kettle excels in noise level, with a peak of 66.3 dB compared to the Fellow's higher noise output, and it provides a more aesthetically pleasing design with its blue LED ring and matte finish. The Cosori's lack of plastic contact with water is a significant advantage over many competitors, including the Fellow EKG, which uses plastic components. In terms of value, the Cosori Electric Kettle offers a balance of features and price, making it a strong contender in the mid-range electric kettle market, though it doesn't quite match the performance of high-end models like the Fellow Stagg EKG.
Value at This Price
The Cosori Electric Kettle is priced at $25.99 for the black model, according to cosori.com, which represents good value for its features and performance. Shouldit.com rated the overall score at 8.0, with a performance rating of 8.6, indicating that the kettle delivers on its promises. The kettle's fast boiling time, quiet operation, and lack of plastic contact with water provide good value for money. However, the average heat retention and lack of temperature control or keep warm function may be seen as drawbacks that could affect long-term satisfaction. The kettle's design and build quality were rated 7.6/10 for usability and 7.6/10 for design, showing that while it's not the most premium option, it offers solid value for its price point. The inclusion of a 2-year warranty and detailed user manual adds to its overall value proposition, making it a reliable choice for budget-conscious consumers.
Long-Term Durability
Based on the reviews, the Cosori Electric Kettle is built to last with its 100% stainless steel construction and borosilicate glass carafe, which are both durable materials. The kettle's design includes a pop-up lid, non-slip handle, and a thumb rest, which contribute to its longevity and ease of use. The inclusion of a 2-year warranty and detailed user manual suggests that the manufacturer stands behind the product's durability. However, some reviewers noted that the exterior gets very hot during use, which could be a concern for long-term durability. The kettle's lack of insulation means that prolonged use might lead to wear on the handle or base. Despite these concerns, the kettle's overall build quality and materials indicate that it should provide reliable performance for several years with proper care and maintenance. The lack of plastic contact with water also ensures that the kettle will not degrade over time, maintaining its safety and functionality.
