Summary

The Hamilton Beach 40850 is a 1.7 L double-wall glass electric kettle with 1500 W heating, automatic shutoff and five LED colors that shift from purple to red as the water heats. Check the evidence before you buy: no instrumented test of this exact model has been published, so the claim that it keeps water warm 29% longer than the single-wall 40865 rests on Hamilton Beach’s own figure.

Strengths

  • Double-wall glass with a stainless steel interior and base; the exterior stays cooler than single-wall glass.
  • 1500 W brings 1.7 L to a rolling boil in around 4 minutes (Macy’s listing).
  • Automatic shutoff at boil and boil-dry protection.
  • Five LED colors read the water temperature at a glance.
  • Lifts off its base for cord-free serving, with a wide push-button lid and a removable mesh filter.
  • The manufacturer claims the double-wall body keeps water warm 29% longer than the single-wall 40865.

Weaknesses

  • No instrumented test of the exact 40850 exists; the measured data comes from sibling models.
  • The 29% heat-retention claim is manufacturer-stated and independently unverified.
  • Retailer listings mislabel it: Lowe’s calls it 4-cup and Home Depot calls it a “stainless steel base corded kettle”.
  • The manufacturer lists no keep-warm function, unlike the 40851 sibling with its 30-minute keep-warm.
  • Weight is unpublished, which matters when the kettle is full.
  • Direct owner reviews are sparse and the manufacturer page shows none.

What the tests cover

No instrumented test of the 40850 was found from any established appliance outlet. The closest measured data is from its siblings. Consumer Reports tested the 40865, the single-wall model in the heat-retention claim, and rated it very good at boiling and convenience, excellent at cleaning and good at cooling. Shouldit tested the 40880 stainless steel kettle, which shares the 1500 W rating and 1.7 L capacity: 7 min 4 sec to boil 1.5 L from room temperature, 152 Wh of energy, 72.8 dB peak noise, and a drop from 212°F to 202°F in 5 minutes with no keep-warm. Treat those as context for the Hamilton Beach 1.7 L line, not measurements of this kettle.

Owner reports

Owner discussion of the exact model is thin. The manufacturer page showed no reviews at the check date, and Lowe’s showed none. A Reddit post in r/BIFLfails describes a Hamilton Beach kettle that failed within a week on an auto-shutoff fault, but the model is not confirmed as the 40850, so treat it as a single anecdote. Across the wider Hamilton Beach kettle line, Best Buy reviews of the 40880 mention occasional lid leakage and a chemical smell on first use.

Cleaning, filters and running costs

Routine upkeep is descaling: rinse and empty the kettle after each use to limit scale, and descale periodically with cream of tartar or vinegar. The mesh filter is removable for cleaning. There are no proprietary consumables. Hamilton Beach sells the kettle for $50.99 direct, and Home Depot listed it at $50.95 in October 2026.

Warranty and repairs

The manufacturer page does not state a warranty term. Hamilton Beach’s kettle Use & Care guides give a one-year limited warranty from the date of purchase for US and Canadian buyers, and exclude glass, filters, normal wear, and damage from accident, alteration, abuse or misuse. Hamilton Beach sells replacement parts through its website, though specific 40850 parts such as the base, lid or filter were not confirmed.

Is it worth it?

Around $50 the 40850 is reasonable for a double-wall glass kettle with LED temperature indication and Hamilton Beach’s parts and warranty support. Above about $56 you are paying a premium over the 40880 and 40864 siblings without gaining independent test data, and past $70 the evidence gap is hard to justify. The 29% heat-retention claim is the manufacturer’s own and remains unverified, so weigh it as an estimate rather than a measured result.

Which model this is

This page covers the Hamilton Beach 1.7 L Double Wall LED Kettle, model 40850, sold under the same model number at multiple US retailers. It is a cordless kettle: it lifts off its power base, even though some listings describe it as “corded”. It is distinct from the single-wall 40864 and 40865 glass kettles, the 40880 stainless steel kettle, and the 40851 sibling, which adds a 30-minute keep-warm. The Amazon listing for this model is ASIN B0CG6S239P.
