Overview
The Chefman RJ11-18-PL undercuts most of its competition on price while matching or beating them on capacity and wattage. At $21.99, you get a 1.8L borosilicate glass kettle running 1500W, enough power to boil a full load fast, and enough volume to serve multiple people without refilling.
Borosilicate glass is the right material choice for kettles: it handles high temperatures without stress fractures and lets you see the water level and clarity at a glance. The brushed black finish on the exterior hardware is a reasonable cosmetic choice for a budget glass kettle.
The numbers are what clinch it: 12,600 reviews at 4.5 stars is a level of validation few kettles at any price achieve. The 2.3 lb weight and 8.75 x 6.24 x 9.45-inch footprint are standard and easy to manage. If you are looking for a highly reliable, widely approved glass kettle at an entry-level price, this is the one to beat.

12,600 reviews at 4.5 stars is a standout signal. Buyers across a very large sample consistently rate this kettle highly, which is particularly notable at under $22. Satisfaction appears driven by the price-to-performance ratio and the glass construction's clean look.
Yes. Borosilicate glass is designed to withstand rapid temperature changes and repeated heating cycles. It is the same material used in laboratory glassware and quality tea pots.
How many mugs does 1.8L fill?
Roughly seven to eight standard 8-oz mugs per full fill.
Does the Chefman RJ11-18-PL have a keep-warm mode?
The listed specs do not indicate a keep-warm feature. It appears to be a boil-and-auto-shutoff design.
