The KitchenAid K400 blender is great for most uses and looks and feels durable enough for even professional environments. This bulky blender comes with a big 56 oz jar so you can make large quantities of smoothies or soups at a time. It's very versatile as it can blend both cold and hot liquids, and it creates bar-quality ice quickly. Unfortunately, the jar's lid isn't the easiest to clean, but both it and the jar are dishwasher safe.
The KitchenAid K400 blender is impressive for multi-purpose use. It does a great job of making things like almond butter and smoothies, with all ingredients being processed quickly. It makes bar quality ice in under two minutes, and it can even blend hot liquids. The blender itself feels very well-built and durable, and it's dishwasher safe as well.
The KitchenAid K400 blender is great for making smoothies and protein shakes. It easily creates a well-blended and thick smoothie in under a minute, though they're quite foamy and aren't the smoothest. It can also create bar-quality ice in around 90 seconds. The blender looks and feels very well-built, and while the lid isn't the easiest to clean, both the jar and lid are dishwasher safe, which is nice.
The KitchenAid K400 blender is excellent at crushing ice. It's able to make bar-quality ice in under two minutes without any large chunks left. The blender also looks and feels very well-built, so it should have no problem with being used to blend ice consistently.
The KitchenAid K400 blender is amazing for making soups. It does a great job of blending ingredients evenly and can blend hot liquids. The jar is also very large, so you can make soups in big batches. While the lid isn't the easiest to clean, the jar and lid are both dishwasher-safe.
The KitchenAid K400 blender is excellent for professional use. It does an excellent job of making butters, smoothies, and crushing ice. It also looks and feels impressively well-built, so it should have no problem being used all day. The jar also holds a lot and is dishwasher safe, which is convenient.
The KitchenAid K400 blender is quite similar to the KitchenAid K150 in terms of dimensions and is a bit bulky. It's not as tall as other blenders though. However, it's very heavy, so you'll likely want to store it directly on your counter as moving it around frequently can be a bit of a nuisance.
The KitchenAid K400 blender feels very well-built and durable. The base is made of metal and the plastic jar feels solid and well-built. Unfortunately, the handle grip of our unit feels a bit loose and the lid feels slightly cheap, though not enough to affect the overall build quality too much.
The main jar is large enough for most uses, but isn't quite as big as some other options, like the Ninja Mega Kitchen System BL770. The jar can be put on the bottom rack of a dishwasher, allowing for easy cleaning, which is nice. Unfortunately, the lid of the jar feels a bit cheap, and the handle isn't very comfortable to grip.
The KitchenAid K400 blender doesn't come with any additional jars.
The KitchenAid K400 blender has four very sharp blades. Two are pointed upwards and two are pointed downwards to help create a vortex. Unfortunately, they can't be removed from the jar for cleaning, but on the bright side, they're dishwasher-safe.
The jar's lid is made from a stiff plastic material. It's difficult to clean, but luckily it can be put on the top rack of a dishwasher. The center part of the lid doubles as a measuring cup, which is handy when adding ingredients mid-blend.
The power cord is long enough to reach an outlet on your counter, but you may need to use an extension if all your outlets are near the ground. Unfortunately, the blender doesn't have a compartment to hide the cable when not in use.
Despite showing options from 1-5, you can hear the motor go through 22 different speed increments as you slowly move the dial, allowing you to fine-tune the speed to a very good degree. Unfortunately, despite the max speed not being nearly as high as some other blenders, like the Vitamix Explorian E310, it still gets very loud.
The KitchenAid K400 blender is great at making almond butter. In about five minutes, it creates a spreadable butter that's fairly smooth overall but quite sticky. While the texture is a bit grainy, there aren't any large unprocessed chunks.
The KitchenAid K400 blender is great at making smoothies. It takes about one minute to blend a thick smoothie with no chunks. That being said, smoothies made with this blender have more of a foamy consistency and aren't the smoothest.
The KitchenAid K400 blender only comes with one jar.
This blender is excellent at crushing ice. Unlike the Hamilton Beach Power Elite Multi-Function, this blender can produce bar-quality crushed ice in under two minutes.
The KitchenAid K400 blender has three different program settings for blending (icy drink, smoothie, crushed ice). Unlike the KitchenAid Diamond, it also has a self-clean program.
This blender is decently easy to clean. The jar is very easy to clean after making a smoothie, though unfortunately, sticky materials like almond butter are more difficult. The lid is tough to fully clean, and the angled non-removable blades make it hard to easily clean the jar safely. Luckily, the jar and lid can both be put in the washing machine. If you want something that performs similarly but is easier to clean, check out the Vitamix Explorian E310.
This blender supports hot blending for making soups or Bulletproof coffee, but other than that it doesn't have any extra features.
We've reviewed the 'Black' KitchenAid K400, but it also comes in Silver, Red, Blue Velvet, and White. We expect our review to be valid for these different variants as well since only the color seems to be changing.
The KitchenAid K400 is a great all-around blender that performs well regardless of what you're blending. It also supports hot blending, so you can do soups or other hot mixes, like most KitchenAid blenders we've reviewed. It's also very well-built and feels premium, but it doesn't have a very large main container like some other blenders from Vitamix or Ninja.
The KitchenAid K400 is a better full-size blender than the KitchenAid K150. The KitchenAid K400 is more powerful, and it has a larger jar. Its build quality is better, it offers more speed settings, and it even has a self-clean program. Its smoothie performance is better too. However, the K150 is a bit more barebones in features. It has a similarly great performance to the K400 when making crushed ice or almond butter, but it can take a couple of minutes longer. It's also a bit easier to clean.
The Vitamix A2300 is a better blender than the KitchenAid K400. It's a lot more powerful and also feels better built and more premium. Also, the Vitamix makes smoother nut butter and is easier to clean. The Vitamix's main jar is larger and comes with a tamper. On the other hand, while the KitchenAid is a bit inferior in pretty much all categories, it's a lot more affordable than the Vitamix.
The Vitamix 5200 is a better blender for most uses than the KitchenAid K400. The Vitamix has a more powerful motor which helps it do a slightly better job at making almond butter, smoothies, and crushing ice. It also feels marginally better-built than the KitchenAid and is easier to clean. On the other hand, the KitchenAid isn't quite as bulky and has a smaller pitcher that isn't nearly as tall.
The KitchenAid K400 is a better multi-purpose blender than the Blendtec Classic 575. The KitchenAid feels better built, and it can process almond butter and smoothies quicker and with a better texture. It also has a speed dial, which gives you a bit more control, and it's not as loud at max speed as the Blendtec. However, the Blendtec is easier to clean, and it can produce snow-like ice. It also has an on/off toggle, which is handy.
The KitchenAid K400 is a better full-size blender than the Hamilton Beach Power Elite Multi-Function. The KitchenAid is significantly better built and has a speed dial to give you more control over your blending. It can also process almond butter and crushed ice and make smoothies with a better texture in less time. However, the Hamilton Beach is easier to clean.
