Overview
The Koolatron KKSC7QSS is a 7 qt slow cooker made from stainless steel, finished in gray, and priced around $108. At that size, it can handle whole chickens, large batches of chili, pot roasts, or enough soup for a week of lunches. Touch controls keep the interface clean, and the 12.7 x 10 x 16 in profile is tall but reasonably compact given the capacity.
The standout spec here is the 38 W power rating. For reference, most 6 to 7 qt slow cookers pull 200 to 350 W. At 38 W, this unit runs at a fraction of the energy cost, which could matter if you cook daily or leave it on for 10-plus hours. The trade-off is that it may take longer to reach cooking temperature, particularly for thick or dense foods.
At 13.9 lb, this is a substantial unit. The 320 reviews with a 4.5-star average is a smaller sample than the top-selling models, so there is less data to draw broad conclusions from. Buyers looking for a straightforward high-capacity slow cooker with minimal running costs will find this an interesting option, though the price of $108 puts it in a bracket where higher-wattage alternatives also compete.
Performance notes
Rated at 38 W with a 7 qt stainless steel interior, the KKSC7QSS operates at an unusually low wattage. It measures 12.7 x 10 x 16 in and weighs 13.9 lb. The low wattage strongly suggests extended cook times for large or dense items. Touch controls and 120 V operation are standard for a US household outlet.
What buyers say
The 4.5-star average across 320 reviews is encouraging but represents a modest sample size. Buyers appear satisfied overall, which suggests the cooker performs reliably for its intended use. The smaller review count does make it harder to assess edge-case reliability compared to models with thousands of ratings.
Similar slow cookers, electric pressure and rice cookers, sous vide, food dehydrators, egg cookers, popcorn poppers, and ice cream and shaved ice machines to consider
The 38 W rating is unusually low compared to the 200 to 400 W range typical for 6 to 7 qt slow cookers. This is likely an energy-efficiency design choice, meaning the unit runs much cheaper per hour but will take longer to bring food up to cooking temperature. It is best suited for very long, low-heat cooking sessions.
Is 7 qt the right size for a family?
A 7 qt slow cooker is well suited for families of four to six people or for batch cooking. You can fit a whole chicken, a large pork shoulder, or a full pot of soup. If you are cooking for one or two people regularly, a 4 qt model would be a better fit and easier to store.
Is the Koolatron KKSC7QSS worth $108?
At $108, it sits above many 7 qt slow cookers that use standard wattage. The main reason to pay that premium would be the energy efficiency angle if you run a slow cooker daily. If energy savings are not a priority, there are solid competitors at 6 to 7 qt for $40 to $65.
