KitchenAid K400 Variable Speed Blender KSB4027BM - 56 oz Jar And 1200 Watt Peak Power

The KitchenAid K400 Variable Speed Blender KSB4027BM is built for US kitchens that tackle everything from morning smoothies to nut butters, pairing a 1.5 peak HP motor rated at 1200 watts with a 56 oz BPA-free jar and a sturdy die-cast metal base.KitchenAid lists the KSB4027BM as a K400 Variable Speed Blender with a 56 oz jar and Intelli-Speed Motor Control.

Motor, Jar And Controls

At the heart of the K400 is a 1.5 peak HP motor that KitchenAid and US retailers rate at 1200 watts on 120 volts, giving it enough punch for fibrous vegetables and ice.Crate & Barrel specifies a 1.5 peak HP motor with 1,200 watts and a 3 foot power cord.Best Buy lists the KSB4027 series at 1200 watts, 120 volts and 10 amps.

The included pitcher is a 56 oz BPA-free plastic jar designed with internal ribbing to pull ingredients into the asymmetric stainless steel blade, which cuts at four distinct angles to build a blending vortex.KitchenAid highlights the ribbed jar and asymmetric blade as part of a three-part blending system on the K400 KSB4027BM.TechGearLab describes the 56 oz BPA-free jar and asymmetric four-blade design that works with the vortex.

Control comes from a single dial that offers five variable speeds, a dedicated pulse function and three preset programs for Ice Crush, Icy Drink and Smoothie, plus an automatic Clean cycle.KitchenAid notes that K400 models use a dial to move through variable speeds and provide three preset recipe programs for ice crush, icy drinks and smoothies.An independent review summarizes five speeds, three integrated programs and an automatic cleaning cycle on the K400.

Build, Dimensions And Everyday Use

The KSB4027BM version of the K400 uses a die-cast metal base with tactile knobs and a matte black finish, and the blender unit weighs about 12 lb, which keeps it planted on the counter even at high speed.Crate & Barrel lists the K400 at 1,200 watts, a die-cast metal base, a BPA-free pitcher and a 56 oz jar with markings.Best Buy reports a product height of 15.8 inches and a product weight of 12 lb for the KSB4027 series, with the jar and lid attached.

The pitcher, lid and tamper on the broader K400 line are dishwasher-safe on the top rack, while the base is wiped clean, which simplifies cleanup after thick blends or sauces.Crate & Barrel notes that the K400 accessories are dishwasher-safe, while the base is cleaned with a damp cloth.

Intelli-Speed Motor Control senses the contents of the jar and automatically maintains the selected speed to drive the vortex, so frozen fruit and fibrous greens are pulled down toward the blade rather than bouncing on top.TechGearLab explains that Intelli-Speed Motor Control in the K400 adjusts blade speed based on ingredient weight and hardness.

Price, Warranty And Accessories

KitchenAid positioned the K400 as a mid-priced countertop blender, with launch pricing around $249.99 in the US and current retail prices often cited between roughly $249 and $289 for the core 56 oz jar configuration.FrontDeskReview documents a US launch MSRP of $249.99 for the KitchenAid K400 and notes current retail in the $249-$289 range as of 06/15/2026.

Retailers that carry special editions, such as matte colorways or bundled tampers, often list the K400 around $299.99, reflecting accessory packs and exclusive finishes rather than a different motor or jar specification.A Klarna US comparison page shows multiple stores offering a K400 blender with tamper at around $299.99.

The K400 carries a 5 year limited warranty in the US, which covers defects in materials and workmanship under normal household use when operated according to the instructions.An independent review cites a 5 year limited warranty for the US K400 blender.

Comparison With Glass Jar And Tamper Versions

Within the K400 lineup, KitchenAid offers variants that differ primarily in jar material and included accessories rather than motor output, giving shoppers a choice between lighter plastic pitchers and heavier glass jars or bundled tampers.KitchenAid groups multiple K400 models under the same blender family, including base, tamper and personal jar configurations.Target lists a K400 blender with a 48 fl oz glass jar weighing 14.6 lb and sharing the same 1200 watt motor and five speeds.

Compared with the glass-jar KSB4026 units that hold 48 fl oz, the KSB4027BM plastic jar version offers 56 oz of capacity, trading the extra 8 fl oz for a slightly lighter overall weight that is easier to lift when full.Cooking With Elo notes that the US K400 ships with a 56 oz BPA-free plastic pitcher, while European and UK versions use a 1.4 L glass pitcher.Target confirms a 48 fl oz US glass jar for a K400 configuration and matches the 1200 watt rating and five speeds.

Positioning In The Countertop Blender Segment

With its 56 oz capacity, 1200 watt peak motor and five year warranty, the KitchenAid K400 KSB4027BM lands between basic three-speed blenders and high-end, multi-horsepower machines, targeting home cooks who want smoother textures and reliable ice-crushing without stepping into commercial pricing.TechGearLab characterizes the K400 as a powerful 1.5 horsepower blender with a 56 oz jar, noting its performance in frozen blends and purees compared with other mid-priced units.Cooking With Elo calls the K400 a mid-priced blender and cites an MSRP around $289.99 for certain trims.

For US shoppers deciding between lower-cost blenders with smaller jars and top-tier devices with sound enclosures and variable ramps, the K400 offers a clear tradeoff: more power and capacity than entry models, asymmetrical blades and Intelli-Speed control for better consistency, and a price that typically stays under $300 for the base 56 oz configuration as of 09/04/2026.FrontDeskReview places the US K400 price band between about $249 and $289 and describes the model as a mid-tier blender option.
