It is worth considering only if you find a complete unit in good condition and confirm that its parts fit: the available evidence does not establish current stock, exact CPB-300RA accessory contents, or compatibility across model suffixes.
What the CPB-300RA is—and what the name can tell you
CHOICE classifies the CPB-300RA as a personal blender and labels it discontinued. Its visible listing gives the motor rating as 350 W. Cuisinart’s U.S. CPB-300 product-family page also marks that line discontinued. These sources establish the model’s discontinued status, but they do not show whether a particular seller has a unit available now.

The available product details span the CPB-300 family and different regional suffixes. Cuisinart’s family description lists a 32 oz blending jar, an 8 oz chopping cup, and four 16 oz travel cups. CHOICE lists capacities of 0.9, 0.5, and 0.2 L for the CPB-300RA, but does not identify those values as a precise inventory of included vessels. Check the suffix, market, and included items on the individual unit rather than assuming every family description applies exactly to the RA version.

CHOICE’s visible listing also gives stainless steel construction, a plastic jug, three speeds, dimensions of 38 × 13 × 15 cm (H × W × D), a weight of 1.6 kg, and a noise figure of 82 dB. Those are listing specifications, not a comparative verdict. CHOICE’s expert rating, performance and ease-of-use scores, ingredient-specific scores, and detailed pros and cons are restricted to members, so no public test result here establishes how well it blends a particular ingredient.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

How the cups and blades work
Cuisinart describes the CPB-300 family as a blending and chopping system with High, Low, and Pulse controls, a safety interlock, and two interchangeable blade assemblies. The documented use cases include blending, chopping, grinding, and whipping. Its combination of a larger jar and single-serve cups offers more vessel options than a cups-only setup, but the exact contents of a CPB-300RA package should be verified before purchase.
This is not a cordless blender. The CPB-300C family manual instructs users to plug the base into an outlet. It describes attaching a vessel with the appropriate blade assembly to the base before operating the controls.

Can it handle frozen fruit or ice?
The available CPB-300RA listing and manufacturer materials cited here do not establish a tested result for frozen fruit or ice, so they are not enough to promise a particular texture or capacity. The manual does advise cutting food into small pieces for more even results and avoiding overloading. Follow the manual for the exact vessel and blade assembly, and do not treat the 350 W rating as proof of performance with a specific ingredient.
What to check before buying a used or remaining-stock unit
- Confirm that the label says CPB-300RA and compare the included cups, lids, jar, and blade assemblies with the seller’s description.
- Inspect every vessel for chips or cracks and every blade assembly for damage. Do not use damaged parts.
- Check that the correct vessels and blade assemblies are present. The model-family documentation does not establish that parts with CPB-300, CPB-300W, CPB-300C, or other suffixes fit every CPB-300RA unit.
- With the parts correctly assembled, check that the controls and safety interlock operate as intended. Do not test the motor with an improperly assembled unit or try to defeat the interlock.
- Ask Cuisinart to confirm a replacement part’s exact part number and compatibility with your unit before ordering. The official product page lists some accessories, but a listing is not proof of current stock or RA compatibility.
- Compare the full cost, condition, included accessories, seller, and return policy with a currently supported blender before deciding.
CHOICE displays $179.00 on its page, but the accessible listing does not establish when that figure applied. It is not reliable evidence of a current buying price.

Replacement parts and warranty limits
Cuisinart’s discontinued CPB-300 page lists some parts, including a chopping cup, chopping cup lid, blending jar cover, and chopping assembly. That offers a possible route to replacements, not assurance that any item is in stock or compatible with every regional version. Confirm both the suffix and part number with Cuisinart before buying.
The CPB-300C manual is a Canadian document for the C-suffix model. It describes a limited three-year warranty for normal home use, subject to exclusions. Those terms should not be assumed to apply to a CPB-300RA in another market, a secondhand purchase, or a unit outside its warranty period.

Safety and cleaning guidance
The CPB-300C manual says removable parts are top-rack dishwasher safe; wipe the base clean and never submerge or put it in a dishwasher. Unplug the appliance before cleaning or adding or removing parts, and keep hands away from the blades.

- Do not blend hot liquids in the travel cups or chopping cup, and do not use carbonated liquids.
- Do not bypass the safety interlock. The manual states: “Do not attempt to bypass the interlock system that powers the unit on.”
- If the motor stops because of an overload, unplug the unit and let it cool for at least 15 minutes before removing some food and resuming.
How to judge it against another personal blender
There is not enough public, comparable test evidence here to declare the CPB-300RA better or worse than another model. For a useful comparison, check the factors that can change how well an older unit fits your needs:
Best Value
- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.
- Powerful Pass-Through Charging: Supports up to 85W pass-through charging so you can power up your laptop while you use the hub. Note: Pass-through charging requires a charger (not included). Note: To achieve full power for iPad, we recommend using a 45W wall charger.
- Transfer Files in Seconds: Move files to and from your laptop at speeds of up to 5 Gbps via the USB-C and USB-A data ports. Note: The USB C 5Gbps Data port does not support video output.
- HD Display: Connect to the HDMI port to stream or mirror content to an external monitor in resolutions of up to 4K@30Hz. Note: The USB-C ports do not support video output.
- What You Get: Anker 332 USB-C Hub (5-in-1), welcome guide, our worry-free 18-month warranty, and friendly customer service.
- Vessels: Does the other blender include a larger jar as well as single-serve cups, and what capacities are documented for each?
- Controls and functions: Compare speed and pulse options, blade arrangements, and documented uses.
- Parts: Verify accessory compatibility and whether replacement vessels or blades can actually be obtained for the exact model.
- Care: Compare the manufacturer’s dishwasher and cleaning instructions.
- Practical specifications: Compare power ratings, footprint, weight, and noise only when equivalent figures are available for both products.
- Evidence and ownership risk: Consider whether independent test results are accessible, whether the model is supported, and the condition and return terms of the specific unit.
