KOIOS Gooseneck Electric Kettle +/-1F Temp Control 0.8L (Matte Black) Review (2026)

Who this kettle suits

This kettle is built for pour-over coffee and tea drinkers who care about hitting a specific water temperature consistently, rather than eyeballing when a stovetop kettle looks about right. Its plus or minus 1 degree Fahrenheit accuracy makes it useful for anyone following a specific brew recipe that calls for a set temperature, whether that is a lighter tea that needs cooler water or a darker roast pour-over that wants water closer to boiling. The matte black gooseneck design also suits anyone setting up a dedicated coffee bar where the kettle sits out on the counter rather than being stored away. Someone who only ever needs boiling water without caring about precise temperature would not need this level of control and could use a simpler kettle instead.

Capacity, power and heating speed

The KOIOS kettle holds 0.8L and runs on 1200 watts, which the brand states can bring a full tank to a boil in roughly 3 to 5 minutes. Temperature can be set anywhere between 100 and 212 degrees Fahrenheit, adjustable in 1 degree increments, and an LCD display on the base shows the preset temperature, the current water temperature, holding time, and operating status. Once water reaches the target temperature, a keep-warm function holds it there for up to 4 hours, useful for brewing multiple cups or drinks back to back without reheating from scratch each time.

Build, spout design and safety features

The kettle body, lid, and spout are made from 304 food-grade stainless steel without chemical linings, and KOIOS states the housing is free of BPA. The spout uses an 8mm gooseneck design paired with an insulated handle, intended to give a smooth, steady pour for controlled pour-over brewing rather than a fast, hard-to-aim stream. Safety features include auto shut-off and boil-dry protection, which stops the heating element if the tank runs low or empty. A mute mode is also available for quieter operation. KOIOS backs the kettle with a one year warranty and ETL approval, and the unit is built for 120V, 60Hz power used in the US and Canada.

How it compares in this site's gooseneck kettle guide

In this site's best electric gooseneck kettles guide, the KOIOS kettle ranks third of eight with a score of 8.4, behind two Fellow Stagg models that each score 9.0, and ahead of an INTASTING and a WILLOW kettle both scoring 7.8. Against the higher-ranked Fellow kettles, the KOIOS offers a lower price point while matching the core feature of tight temperature control, though it lacks the color LCD screen of the Stagg EKG Pro. Compared with the similarly priced COSORI kettle also in this guide, the KOIOS uses a numeric 1 degree adjustable temperature setting rather than COSORI's five fixed presets, giving slightly more granular control for recipe-focused brewers.

Verdict

The KOIOS gooseneck kettle is a strong pick for pour-over and tea drinkers who want fine-grained, repeatable temperature control without paying premium prices for a Fellow Stagg, and its stainless steel construction and 4-hour keep-warm function support a daily brewing routine well. The 0.8L tank is the main limitation for anyone regularly brewing large Chemex batches or serving several people at once, and the electronic base needs to be kept away from water during cleanup. For solo or two-person pour-over routines focused on consistency, it is a well-equipped, reasonably priced option.
