The Chefman RJ11-10-GMRL is a compact 1-liter borosilicate glass kettle that earns strong marks from a large review base, though the absence of a listed price makes comparison shopping harder. Its 1500W element brings a liter of water to boil quickly, and the matte black finish gives it a cleaner look than most budget glass kettles.
Solo users or couples who want a fast, small-capacity glass kettle with a modern matte look. Also suits anyone who prefers to see the water level through the borosilicate glass body.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other coffee makers, kettles and brewers we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
At 1 liter, this kettle is sized for one to two cups at a time. Borosilicate glass is a practical material choice: it resists thermal shock better than standard glass and doesn't add any taste to the water. The matte black finish (7.68 x 5.67 x 7.8 in, 1.7 lb) is more understated than the shiny alternatives in this price range.
The 1500W rating is on the higher end for a 1L kettle, which means boil times are short. With 7,400+ reviews and a 4.6-star average, it has a substantially larger feedback pool than most kettles at this size. That volume of ratings points to consistent satisfaction rather than a handful of outliers.
The main practical consideration is capacity: 1 liter is roughly 33 oz, enough for two standard mugs. If you routinely make tea for a household, you will be refilling often.

Performance notes
1500W at 1L is a favorable power-to-volume ratio that supports fast boil times. Borosilicate glass construction handles rapid temperature changes without cracking. The kettle weighs 1.7 lb empty, which is light for a glass model and easy to handle one-handed.
What buyers say
Over 7,400 reviewers give this kettle a 4.6-star average, which is unusually consistent for a glass kettle. Buyers at this volume and rating tend to be satisfied with basic performance, fast boiling and durable glass, without expecting premium extras like temperature presets.
