The Panasonic NN-SN76LS is a 1.6 cu ft, 1250W stainless steel countertop microwave at $329.95 with a 4.0-star average from 271 reviews. It offers one of the more spacious cavities in the sub-$350 range and enough wattage for fast everyday cooking, though the 4.0-star average suggests some buyers find room for improvement at this price.
Households that routinely cook or reheat larger portions and want a high-capacity countertop microwave with real wattage. At 1.6 cu ft and 1250W, this is among the more powerful non-commercial options and suits families, batch cookers, or anyone who regularly uses full-size casserole dishes.

Skip if you are on a tight counter or want the best reviewed Panasonic in the $300-$350 range. A 4.0-star average from 271 reviews is acceptable but not exceptional for Panasonic, and closely related models with better track records exist. Also skip if the 21.88-inch width is too large for your available space.

Overview
Panasonic's NN-SN76LS leads with capacity: at 1.6 cu ft and a 13.4-inch turntable within a 21.88-inch-wide body, it is built for users who find 1.2 and 1.3 cu ft units cramped. The 1250W wattage puts it in the upper tier for residential countertop units, heating food about 10 to 25 percent faster than standard 1000W models. With 11 power levels and a keypad interface, it gives practical granular control without excessive complexity.
At $329.95 with 76 units bought last month, this model has steady real-world demand. The 4.0-star average from 271 reviews reflects a functional, well-built unit where the main complaints likely center on value relative to price rather than reliability failures. At this wattage and capacity in stainless steel, Panasonic's pricing is in line with comparable models from GE and Toshiba.
The stainless steel finish and 32 lb weight indicate a solid construction, though the unit is light enough to reposition on the counter without effort. The keypad-only interface is a reasonable choice: more tactile than flat touchscreens without adding dial controls that can wear over time.

Performance notes
The 1250W output is noticeably faster than standard 1000W units. A plate that takes 2 minutes at 1000W will heat in roughly 90 seconds at 1250W, a real difference in daily use. The 1.6 cu ft interior with a 13.4-inch turntable fits a full 12-inch dinner plate with clearance on all sides, and large covered soup bowls or rectangular storage containers clear the ceiling comfortably. The 11 power levels span from about 115W to 1250W, giving practical control over defrost and warm settings. Keypad controls require no learning curve for experienced microwave users.
What buyers say
At 271 reviews averaging 4.0 stars, most buyers are satisfied with the NN-SN76LS as a high-capacity everyday microwave. The rating suggests the unit works as expected but does not exceed expectations in the way that 4.3 to 4.5-star Panasonic models do. Buyers who want the largest common countertop cavity with reliable brand quality will find this acceptable; those prioritizing the best value or rating may want to compare closely before committing.
Is 1.6 cu ft significantly larger than 1.2 or 1.4 cu ft microwaves?
In practical terms, yes. A 1.6 cu ft interior is noticeably roomier for tall containers, wide casserole dishes, and large dinner plates. The difference between 1.2 and 1.6 cu ft is roughly a 30 percent increase in volume, which matters for households that regularly heat full meals or large quantities at once.
What is the difference between 1250W and 1000W in daily use?
1250W delivers 25 percent more power than 1000W, which reduces cook times proportionally. A task that takes 2 minutes at 1000W takes about 96 seconds at 1250W. For frequent daily use, that adds up. The higher wattage also means the unit reaches full heating temperature more quickly, which can improve food quality by reducing the window where some parts overheat while others are still cold.
How does the NN-SN76LS compare to the Panasonic NN-SD78LS?
The NN-SD78LS also offers 1.6 cu ft and 1250W at $399.95, with a 4.1-star average from 269 reviews and a button-and-dial control interface versus the NN-SN76LS keypad. Both are closely matched in specs; the NN-SN76LS is priced $70 lower. The choice between them comes down to control interface preference and which unit is available at a given time.
