Fellow Stagg EKG Pro: What to Know
Fellow's own spec sheet lists a 0.9-liter (30-ounce) capacity and a 1000-1200W heating element running on 110-120V household current, putting it in the middle of the pack for power but at the small end for capacity among the five kettles in this guide.
What sets it apart is adjustment granularity: Fellow states the kettle can be set to-the-degree across a 104F-212F (40C-100C) range in roughly 0.5F increments, controlled through a rotary dial on the base rather than a small handful of fixed presets. An adjustable hold mode (15, 30, 45, or 60 minutes) keeps water at the chosen temperature once it's reached, which matters for anyone dialing in a specific pour-over recipe rather than just wanting hot water.
The tradeoff for that precision is scale: at well under a liter, the Stagg EKG Pro is sized for single-serve pour-over or a couple of cups of tea, not for filling a large teapot or French press for a household. Fellow also sells a 'Pro Studio' edition with a glass base and, on some listings, added connectivity -- a different product from the standard Pro reviewed here, and buyers should be careful not to conflate the two on a crowded Amazon results page with many color and handle variants.
