Kitchenaid Blender Plastic Jar Review
KitchenAid Go Personal Blender Jar
ADVANTAGES
LIMITATIONS
The KitchenAid Go Personal Blender Jar is a game-changer for smoothie lovers who live on the move. With its 16 oz BPA-free plastic jar and vortex-optimized design, it pulls ingredients down directly onto the blades—no more scraping half-blended chunks from the sides. The specially engineered blade tears through frozen fruit and ice like a mini avalanche, delivering silky-smooth results in seconds, all while pairing seamlessly with the cordless KSBR256 and KSBR200 blenders. If you hate clumpy post-workout shakes or messy countertop transfers, this compact powerhouse erases those frustrations with smart, portable engineering.
In real-world testing, the jar shines during morning prep and gym commutes—blend a protein shake directly in the jar, snap on the leak-resistant travel lid, and go. At 16 oz, it’s ideal for single servings, though pushing beyond that leads to overflow risks. The plastic builds up fine scratches over time, especially with fibrous greens, but it’s dishwasher-safe and holds up well to daily use. While it won’t tackle family-sized batches or thick nut butters, it’s not meant to—this is precision blending for one, optimized for speed and portability.
Compared to larger KitchenAid jars, this personal model trades capacity for convenience, making it a smarter choice than the bulky 60oz options when mobility is key. It’s not a replacement for full-size blending tasks, but for users prioritizing on-the-go efficiency, it outshines generic travel blenders. While the 6-oz small batch jar is better for baby food or dressings, this 16 oz version strikes the sweet spot between portion size and portability. For personal blending that’s fast, clean, and truly go-ready, the KitchenAid Go jar beats bulkier alternatives in agility and integration.
6-oz Small Batch Jar Pack
ADVANTAGES
LIMITATIONS
Precision meets practicality with the 6-oz Small Batch Jar—a must-have for anyone tired of wasting ingredients on oversized containers. This BPA-free plastic jar is engineered specifically for the KitchenAid K150 and K400 series, delivering powerful blending in a compact form that excels at tiny but mighty tasks like baby food, herb pastes, or single-serve sauces. The sealed storage lid means you can blend pesto one night and stash it directly in the fridge—no transferring, no mess. For home chefs and parents, it solves the all-too-common problem of over-prepping with under-delivering results.
During testing, the jar consistently handled thick blends like hummus and avocado dips without stalling, thanks to its optimized blade-to-jar ratio. At just 6 oz, it’s not meant for smoothies or soups for two, but that’s exactly the point—micro-batching has never been this efficient. The plastic is lightweight and dishwasher-safe, making cleanup a breeze, though aggressive scrubbing can lead to surface scuffs over time. It integrates flawlessly with compatible blenders, but don’t expect it to replace your main jar—this is a specialist tool, not a generalist.
When stacked against the 16 oz Go Jar, this one wins for culinary precision, while the Go Jar dominates in mobility. It’s also a smarter investment than the 60oz replacement jar if your needs skew toward condiments and starters rather than full meals. While pricier per ounce, its blend-and-store functionality justifies the cost for frequent small-batch users. If you regularly make tiny portions and hate food waste, this KitchenAid KSB2040BBB expansion pack offers unmatched convenience and kitchen efficiency.
60oz Plastic Blender Jar WPW10514321
ADVANTAGES
LIMITATIONS
When your original blender jar cracks or leaks, the 60oz Plastic Blender Jar Assembly WPW10514321 steps in as the most durable and exact-fit replacement for select KitchenAid models. Crafted with high-impact BPA-free plastic, this 60-ounce workhorse is built to handle everything from silky tomato bisque to chunky salsa without warping or clouding. Its precision-engineered base ensures seamless alignment with the motor drive, eliminating wobble and vibration—common pain points with third-party jars. For owners of older KSB1575 or 5KSB1585 series blenders, this isn’t just a fix—it’s a performance reset that restores like-new reliability.
In daily use, the jar proves its mettle with heavy-duty tasks: blending hot soups straight from the stove, crushing ice for pitchers, and emulsifying dressings without separation. The large capacity makes it ideal for families or meal preppers, though the size becomes unwieldy for single servings. The plastic is resistant to staining and odors, even after repeated use with turmeric or beets, and cleanup is straightforward—either hand wash or toss it in the dishwasher. That said, the sheer size means it doesn’t fit under most cabinet shelves when filled, a minor but real kitchen constraint.
Compared to the 16 oz Go Jar or 6 oz small batch model, this is the heavy-duty backbone of the KitchenAid ecosystem. It lacks portability and micro-batch precision but dominates in volume and durability. While the 9704200P offers a cheaper alternative, this OEM-grade assembly delivers superior fit and long-term reliability. For users who rely on consistent, high-volume blending and own a compatible model, this WPW10514321 jar is the premium fix that keeps a trusted blender running for years.
Plastic Blender Jar 9704200P
ADVANTAGES
LIMITATIONS
The 9704200P Plastic Blender Jar is the budget-savvy lifeline for KitchenAid blender owners facing a cracked or worn-out jar. At just over 60 oz, this direct-fit replacement works with multiple KitchenAid and Whirlpool models, offering a no-frills solution that gets the job done without the premium price tag. While it lacks branding flair, the BPA-free plastic construction holds up reasonably well to daily blending—smoothies, shakes, and light sauces all process smoothly when paired with a functioning motor base. For users needing a quick, functional fix without long-term investment, this jar removes the hassle of hunting for OEM parts.
In testing, the jar performed adequately with soft and moderately thick blends, but showed signs of vibration and slight wobble on higher speeds, likely due to minor tolerances in manufacturing. It doesn’t seal quite as tightly as the WPW10514321, raising minor concerns about long-term leak resistance, especially with hot liquids. The plastic feels thinner and more prone to surface scratches, though it remains clear and stain-resistant with regular cleaning. It’s best suited for light to moderate use—don’t expect it to crush ice daily or handle heavy doughs.
Against the pricier WPW10514321, the 9704200P clearly trades build quality for affordability, but for temporary use or secondary blenders, that’s a fair trade. It doesn’t offer the precision of small batch jars or the portability of the Go system, but as a low-cost, functional replacement, it keeps your blender alive without draining your wallet. If you need a short-term fix or a spare jar for backup, this model delivers basic reliability at the lowest entry point.
Choosing the Right KitchenAid Blender Jar
Replacing a damaged KitchenAid blender jar, or having an extra on hand, can save you from needing to replace the entire blender. However, with several options available, selecting the right jar requires considering a few key factors. Here’s a breakdown to help you make the best choice.
Capacity & Intended Use
The size of the jar you need is crucial. KitchenAid blender jars commonly come in 56oz and 60oz sizes for standard blending, but also smaller 6oz and 16oz options for specific needs.
- Standard 56oz/60oz Jars: These are ideal for everyday blending tasks – smoothies, soups, sauces, and crushing ice for larger groups. If you frequently make batches for a family, this is likely your best bet.
- 6oz Jars: Excellent for small-batch blending, like baby food, dips, or single-serving smoothies. These are often sold in packs and are perfect for minimizing waste.
- 16oz Jars (Go Personal Blender): Designed for convenience and portability, these jars are specifically for the KitchenAid Go Cordless Blender and are great for on-the-go smoothies and shakes.
Model Compatibility
KitchenAid blenders have different model lines, and jars aren’t universally interchangeable. This is the most important factor to consider.
- Check Your Blender’s Model Number: Locate the model number on your blender (usually on the base).
- Refer to Compatibility Lists: Most replacement jars will list the specific KitchenAid models they are compatible with. Carefully compare this list to your blender’s model number. Don’t assume a jar will fit just because it looks similar.
- Part Numbers: Replacement jars often have multiple part numbers (the original and those it replaces). Using these part numbers in your search can also help guarantee a correct fit.
Material & Durability
KitchenAid blender jars are typically made of plastic. While generally durable, the quality of plastic can vary.
- BPA-Free Plastic: Ensure the jar is made from BPA-free plastic for safe food preparation. Most modern jars are, but it’s always good to check.
- Jar Thickness: A thicker plastic jar generally indicates higher durability and resistance to cracking.
- Replacement vs. Original: Aftermarket replacement jars may differ in plastic quality compared to the original KitchenAid jar. Reading reviews can provide insights into the durability of specific replacement options.
Other Features to Consider
- Ease of Cleaning: Dishwasher-safe jars are more convenient.
- Lids & Seals: Ensure the jar comes with a properly fitting lid to prevent leaks during blending and storage.
- Blade Assembly: Some jars are sold as complete assemblies (jar + blade), while others require you to reuse your existing blade. Confirm what’s included.
- Warranty: A warranty offers peace of mind and protection against defects.
