Container packages
KitchenAid Pure Power jars: plastic, glass or both?
KitchenAid's Pure Power name covers several packages that look similar on the counter but arrive with different containers. The practical decision is not just plastic versus glass: compare each vessel's nominal capacity, whether a second large jar is in the box, and whether you need a small personal cup. These are separate setups on the same base. A larger capacity on one jar does not raise the fill limit of another.
Compare the three full-size jar packages
| Exact package | Included full-size vessels | What it fits | Main constraint |
|---|---|---|---|
| KSB2072BM | One 68 oz BPA-free plastic jar and lid | Plastic-jar preference; a nominal 64 oz capacity floor | No glass or personal jar included |
| KSB2070BM | One 62 oz glass jar and lid | Glass preference when a 48 oz floor is enough | Below a nominal 64 oz requirement |
| KSB2076BM | One 68 oz BPA-free plastic jar and one 62 oz glass jar | Two full-size materials available in one package | Only the plastic jar reaches 64 oz; capacities cannot be combined |
The glass-only family also appears in finish SKUs. KitchenAid's exact Agave KSB2070AG listing names the same 62-ounce glass jar, base and lid, and repeats the Pure Power control menu; it does not create another operating plan. The Black Matte KSB2070BM assessment therefore remains the useful package comparison for a shopper who is choosing Agave for color. Confirm the full suffix and listed contents for the exact finish you intend to buy.
Let your batch requirement choose the vessel
If your minimum is 48 ounces, either the 62-ounce glass plan or the 68-ounce plastic plan can meet the nominal capacity threshold. A 64-ounce minimum is different: only the 68-ounce plastic setup qualifies. KSB2076 can still qualify for a 64-ounce shopper if you are willing to use its plastic jar. It must not qualify for the more restrictive combination “glass jar and at least 64 ounces in that same operation,” because its glass plan is 62 ounces. The matcher treats that as an incompatible pair instead of borrowing the capacity from the other jar.
Capacity on a product card also is not a safe finished-fill line. KitchenAid's Pure Power product guide says not to exceed the highest jar measurement mark and limits hot liquid to 40 ounces. The owner safety guide says to keep the lid center cap in place for hot contents and start on the lowest speed before slowly increasing. A 62- or 68-ounce listing should therefore not be read as approval to fill that much hot soup.
The common controls do not erase package differences
All three exact pages describe ten manual speed settings, a knob that can move between settings, Pulse, and the named Smoothie, Ice Crushing and Clean controls. Clean is a wash routine, not an extra recipe class. The product guide's care steps use warm water and one or two drops of dish detergent in a half-filled, seated jar for 15 seconds, followed by emptying and rinsing. The safety manual specifically allows the lid and center cap on the dishwasher's top rack, but does not make the same blanket statement about the jars in that section. Follow the full current care directions for each vessel instead of guessing that the two materials have identical care rules.
The 1,700-watt peak input figure appears on the product pages with a footnote distinguishing it from power at the blade, and the page lists 1,200 watts UL-rated. The number is a specification, not a blender-performance test. If you are choosing by texture, use the control descriptions and recipe needs as a guide, but do not treat wattage or an ice-crushing claim as a promise about a specific load.
When to include a personal jar
The full-size plastic/glass models above do not list personal cups in their boxes. KSB2079ER adds one 16-ounce personal jar and KSB2078DG adds two, alongside a 68-ounce plastic main jar. Those are different bundles. The owner manual warns not to blend hot ingredients or grind in the personal jar. A personal vessel makes sense when a cold single serving is part of the routine; it does not replace a 62-ounce glass jar or turn into another family-size container. Compare the one-cup and two-cup reviews before adding an accessory that is not included in the exact model you are considering.
In short: choose KSB2072 if you want the larger plastic jar, KSB2070 if a glass vessel at 62 ounces is sufficient, and KSB2076 if you value having both large jars on hand. The decision changes if you require a minimum in the same vessel, want a travel cup, or need to keep hot blends below the maker's stated limit. Verify the complete model suffix and box contents before buying; the family name alone does not tell you which jar package you are receiving.
