Cosori Electric Kettle with Temperature Control, 6 Presets, 1.7L, Black
The Cosori CO117-DK pairs a borosilicate glass body and 304 stainless steel base with six stepped temperature presets for everyday beverage preparation. While it eliminates interior plastic contact, serious tea drinkers may lament the absence of degree-by-degree adjustments and an integrated infuser basket.

Best for Everyday tea drinkers wanting broad temperature presets
This unit offers six temperature presets and generous 1.7-liter capacity at an accessible mid-tier price point. It lacks single-degree adjustments, meaning delicate greens must conform to fixed intervals. Check whether internal components or lid inserts introduce plastic into the boil path.

The full review
Design and Build
The Cosori CO117-DK centers its construction on a thermal shock-resistant borosilicate glass carafe flanked by a 304 food-grade stainless steel floor and filter. This structural choice satisfies essential purity standards, as the heated water contacts glass and metal rather than synthetic compounds. Holding up to 1.7 liters (approximately seven standard US cups), the reservoir includes graduated measurement indicators along the glass flank, allowing accurate assessment of water volume. The lid opens to an 80-degree angle, which, combined with a wide-mouth aperture, permits straightforward filling directly from faucets and facilitates reach-in cleaning. The handle integrates a streamlined control pad driven by a British Strix thermostat controller, an industry standard for safety and thermal management. Two distinct LED illumination rings clearly signal the kettle's state, casting blue light during active heating and switching to white when the keep-warm circuit engages. While the exterior relies on matte black plastics for the base and handle assembly, interior water-contact points maintain solid material isolation.
Real-World Performance
Rated at 1500 watts under standard 120-volt operation, the kettle reaches a rolling boil within three to seven minutes depending on start volume. Rather than offering degree-level temperature targeting, the interface confines selection to six pre-programmed thermal settings. While suitable for standard commercial tea categories, this stepped configuration falls short of the precision needed for temperature-sensitive specialty teas that require exact single-degree thermal management. The Strix thermostat regulates temperature targets and initiates automatic shut-off once complete, accompanied by dry-boil safety protection. The integrated one-hour keep-warm cycle operates reliably and includes a one-minute internal memory; returning the pitcher to its powered base within sixty seconds resumes the existing heating program uninterrupted. Users in regions with mineral-dense tap water should expect calcium and magnesium deposits to form on the exposed stainless steel floor after initial boiling cycles. Removing this limescale requires standard periodic descaling using diluted vinegar or lemon juice solutions as directed in manufacturer documentation.
Value for Money
Priced at $53.99, the CO117-DK is situated competitively within the entry-to-mid tier of multi-temperature electric kettles. Its massive user base—evident in nearly 50,000 recorded customer reviews with a 4.5 out of 5 average rating—reflects dependable build reliability and operational consistency. For this price, buyers receive a certified 1500-watt Strix heating mechanism, a 60-minute holding cycle, and predominantly glass-and-steel fluid pathways that avoid leaching plastic tastes. However, from a dedicated tea-preparation perspective, the value proposition requires qualification. Because the unit excludes an internal steeping infuser, users must allocate separate funds for external teapots, gaiwans, or wide-basket strainers to brew loose leaves. Additionally, consumers seeking degree-by-degree programming will find that several direct competitors in this pricing bracket offer digital displays with discrete one-degree controls. For general household water heating and routine loose-leaf steeping where preset approximate bands suffice, the product provides balanced return on investment.
Who Should Skip It
Dedicated tea enthusiasts whose preparations mandate granular, degree-level temperature control should look beyond this model. The Cosori CO117-DK is restricted to six pre-set thermal options, precluding the exact degree increments required for delicate Japanese green teas, rare oolongs, or sensitive white teas. Furthermore, buyers looking for an integrated all-in-one steeping appliance will find this kettle unsuitable. The package includes only the glass pitcher, power base, and user manual; it lacks an internal infuser cage, making direct in-kettle leaf extraction impossible without risking element scorch and cleaning complications. Pour-over coffee practitioners should likewise bypass the unit, as the wide drip-less spout is engineered for rapid vessel filling rather than the restricted, laminar water flow afforded by specialized gooseneck designs. If your routine demands single-degree custom temperatures, integrated loose-leaf immersion, or controlled slow pouring, this conventional preset kettle will prove an inadequate fit for your brewing bench.

Common questions
Does this kettle offer degree-by-degree temperature control?
No, the Cosori CO117-DK does not feature single-degree adjustments. Instead, it operates using six one-touch preset temperatures intended for common beverage categories like green, oolong, and black teas. Brewers who require specific, single-degree temperature tuning must manually monitor water temperature with an external probe thermometer.
Does the kettle include a tea infuser for loose leaves?
No infuser basket is included in the packaging. The unit consists solely of the kettle body, power base, and user manual. Brewing whole-leaf teas requires a separate external teapot or wide infuser basket, as brewing directly in the kettle can damage the internal heating plate and invalidate warranties.
Does heated water touch plastic inside the kettle?
The interior contact surfaces consist of 304 food-grade stainless steel on the bottom heating plate and spout filter, combined with a borosilicate glass body. The structural materials are BPA-free, engineered to avoid imparting synthetic chemical odors or plastic tastes into the heated water during routine operation.
How does the base memory function operate during brewing?
When the kettle is lifted from its 360-degree power base during an active heating or keep-warm cycle, an internal timer initiates a sixty-second countdown. If the kettle is returned to the base within that one-minute window, the unit automatically resumes its selected temperature program without requiring re-entry.
How we judge tea accessories
Rule 01
Degree-level temperature control is the whole point of a tea kettle.
Rule 02
Stainless or glass interiors avoid the plastic-taste problem.
Rule 03
Wide infusers let leaves open; tea balls choke them.
