Chefman Fast-Boil 1.8L Electric Kettle RJ11-18-PL: problems, parts and running costs
Checked: 2026-10-05
Summary
This is a plain 1.8-liter, 1500 W glass kettle with one switch, automatic shutoff and boil-dry protection, and almost everything owners report against it is a limitation rather than a defect: the only failure on record is a single cracked-glass arrival, and there is no established breakdown pattern for the model. Running cost is electricity plus occasional descaling, since there are no filters, pods or subscriptions. It is worth buying at or below $24, still sensible at $27.99, and hard to justify once variable-temperature kettles reach the low thirties.
Common problems and fixes
- Cracked glass body on arrival — one owner of the exact model received a kettle with a small crack in the glass near the top. Treat it as a shipping and packaging caution rather than a defect rate: no wider pattern has been reported, and exact-model searches turned up no independent community corpus that could establish how often this happens. Inspect the glass before you fill it, and if it arrives cracked, that is a return, not a repair. [1]
- No replacement parts for the heater, switch or base — no consumer parts catalog exists for this model, so once the 1-year Chefman warranty is over, a failed heater, switch or base means buying another kettle rather than fitting a part. At this price replacement economics decide it. [2][3]
- Scale buildup — the manual documents routine descaling as normal care, but nothing in the research reports how quickly scale accumulates in hard-water areas or whether it slows the kettle down, so the interval between descales is unknown. If you are in a hard-water area, descale on a fixed schedule rather than waiting for a change in boil behavior. [3]
- The glass vessel is not cool-touch — only the handle is described as cool or stay-cool, so the glass body itself heats up during a boil. Lift and pour by the handle, and expect the body to be hot on the base after use. [2][3]
- Hand wash only — the glass vessel is not dishwasher-safe. The removable lid lifts out completely, which leaves a wide opening, so rinsing and wiping by hand is quick. [2][3]
- No temperature control and no keep-warm — the kettle boils and shuts off, and does nothing else. There is no sub-boil setting for green tea or pour-over coffee and no hold function, so buy it only if plain boiling water is what you need. [2]
- Specifications get mixed between RJ11 variants — seller copy and search results routinely mix this model with the tea-infuser sibling RJ11-18-PL-TI and with RJ11-18-AM and RJ11-17-CTI. Complaints and features from those models do not apply; check the model number RJ11-18-PL on the box. [1][4]
Parts and consumables
No replaceable parts or consumables reported. The stainless filter and spout assembly is part of the kettle rather than a separately sold item, no consumer catalog exists for the heater, switch or base, and there are no filters, pods or descaling products the manufacturer requires you to buy.
Yearly running cost
Electricity for the boil cycles, plus whatever you spend on descaling. There are no scheduled consumables, no filters and no subscription, so the descaling fluid is the only thing you ever have to buy. No source in the research gives a watt-hour figure or an electricity rate for this model, so a yearly total is not enough data; measure it yourself with a plug meter over a week of normal use and multiply.
When it is a good buy
Chefman, Best Buy and Walmart all listed the exact model at $27.99 in September 2026. At $24 or less it is excellent basic-kettle value; at $25–28 it is good to fair; at $29–35 it is mediocre, because richer variable-temperature and infuser kettles start appearing in the low thirties; above $35 it is poor value. Buy it on sale rather than at full price.
Named alternatives from the research, with what each is better for:
- Cosori 1.7L kettle — it has repeatedly occupied the same price band, so it is the comparison to make in the $25–28 range before settling on this one.
- A variable-temperature kettle — the better choice if you make green tea, white tea or pour-over coffee, since this model has no sub-boil control at all.
- A kettle with a tea infuser — the better choice if you brew loose leaf in the kettle; this model is the RJ11-18-PL, not the RJ11-18-PL-TI infuser variant.
