SPT SR-1891B 1300W Induction Cooktop review

SPT’s SR-1891B is an earlier, discontinued one-zone induction cooktop whose exact product page marks it out of stock. Its distinctive documented combination is a 1,300 W maximum, twenty power selections within a stated 300–1,300 W range, three Warm settings, and a timer advertised for up to 9 hours 50 minutes. That is a reference profile for comparing a used or old-stock unit, not evidence that a new one can currently be bought from SPT.

A lower ceiling than newer high-output choices

The maker lists 120 V / 60 Hz and 1,300 W power consumption. It is a single cooking zone, so there is no way to keep two pans heating at once. The 1,300 W maximum is below the 1,650 W SR-1882 and the 1,800 W SR-1886BK; if those figures are important to your decision, read their separate reviews rather than treating the model numbers as interchangeable. A higher rating gives a larger listed input ceiling, but this is not a measured head-to-head cook-time test, and cookware, food quantity and chosen settings also affect a real session.

The SR-1891B page says that its Cook function has twenty power settings spanning 300 to 1,300 W. It does not publish the values for each step, and I found no exact-model user manual linked from that page. Do not assume a particular wattage ladder or infer that every low label delivers that wattage continuously. For someone who needs a specific low-output behavior for delicate foods, the missing step table and operation instructions are material limitations, not details to guess from another SPT model.

Warm settings, not a documented food-temperature system

SPT identifies a separate Cook & Warm function and lists three temperature/keep-warm settings: 140°F, 167°F and 194°F. That supports a limited warming choice, but the page does not document a broad adjustable pan-temperature mode, probe-based measurement, or the way heat cycles to hold each value. These numbers should be read as manufacturer-listed control settings, not readings of the food or a promise that the pan contents stay at exactly that temperature. If you require finely selectable cooking temperatures, an included food probe or a documented control sequence, this page does not establish that fit.

The listing also advertises an LCD for timer and power and calls the feature SmartScan, but does not explain the display sequence or what SmartScan changes in use. It lists a timer of up to 9 hours 50 minutes; without an exact manual I cannot confirm whether expiry shuts the heater off, how the countdown is set, or whether the timer can be used in Warm mode. Do not treat a long maximum timer as permission to leave a cooking appliance unattended.

Check the actual pan and counter setup

The product page describes induction heating for ferromagnetic cookware and automatic pan detection. It does not give a minimum or maximum flat magnetic-base diameter, nor a cookware-shape or flatness tolerance. That omission matters more than the overall pan rim measurement: induction needs a compatible magnetic base, and a cooktop’s sensing footprint can affect whether a small vessel is recognized. If your essential pan is unusually small, large, warped, or has a narrow base, get a model-specific fit answer before relying on an old unit. The SR-1891B should not be counted as meeting a precise base-size requirement on the evidence available here.

SPT lists a body measuring 12 × 14 × 2 inches and a 6.56-foot cord, useful checks for counter space and outlet reach. The same specification block gives net/gross weights of 6.75/8 pounds, while a separate page-level weight field says 10 pounds. I would use the listed net figure only as a rough carry-planning clue and would not trust either shipping-weight number without confirmation. The page identifies a black-on-black glass-ceramic design, but does not provide a clearance requirement, circuit instruction, or explicit outdoor-use approval. Keep it on a stable counter and follow the supplied instructions if they can be obtained with the specific unit.

Who should compare another model

This profile may interest a shopper documenting an existing SR-1891B, or someone deliberately considering an exact older model who is comfortable verifying condition, supplied accessories and instructions with the seller. Its 1,300 W cap, one-zone format and three named Warm settings are straightforward; its sparse documentation makes several day-to-day details less certain than on a model with a fully identified owner manual. No current SPT stock, parts availability, used condition, remaining warranty, or tested performance is established by this review.

If a larger listed power ceiling is a priority, compare the SPT SR-1886BK, whose exact page and model-cover manual document 1,800 W and a different set of controls. If a more thoroughly documented earlier SPT alternative is useful, the SR-1882 review explains its nine Cook labels, cookware-base range and a discrepancy between its operating manual and installation sheet. Those facts do not transfer to the SR-1891B. In particular, neither the SR-1882 pan range nor the exact manual behavior of another SR-18-series cooker should be used to fill this model’s documentation gap.
