If “Acer Chromebook 14” means the CB3-431, choose a current Chromebook Plus model for a new primary laptop. Google lists automatic updates for the CB3-431 only through June 2022, so it no longer receives the normal ChromeOS, browser, security, bug-fix and feature updates. “Chromebook Plus” is not one laptop, either: it is a category with minimum hardware requirements and several Acer models. The practical choice is therefore between an unsupported legacy CB3-431 (usually relevant only as a very cheap used device) and a specific Chromebook Plus configuration, such as the Acer Chromebook Plus 514, whose exact model number determines its specifications and support date.
At a glance
| Name | Best for | Key spec | Platforms | Checked |
|---|---|---|---|---|
| Acer Chromebook Plus 514 | New buyers who need a supported primary Chromebook | 14-inch WUXGA display; family configurations up to 16 GB memory and 512 GB storage | ChromeOS | Nov 2026 |
| Acer Chromebook 14 CB3-431 | Only a very low-cost legacy or temporary device | Google-listed automatic-update end date: June 2022 | ChromeOS | Nov 2026 |
Google’s sources do not establish a current retail price or stock position for either row. Check the exact SKU and today’s listing before paying; “up to” specifications for the Chromebook Plus 514 describe a family range, not every configuration.
What exactly is the “Acer Chromebook 14” in this comparison?
The name is incomplete without a model number. This comparison uses the CB3-431 because that is the Acer Chromebook 14 model identified in Google’s Auto Update policy. Acer has sold other Chromebook 14 variants, and their processors, displays, storage and support dates can differ. If the label on your machine, listing or box shows another code, do not apply the CB3-431 conclusion until you check that code’s own schedule.
Google calls the automatic-update end (AUE) date the most reliable way to judge a Chromebook’s age and remaining official support. Use Google’s update-schedule instructions and the model’s full identifier, rather than relying on a seller’s title such as “Chromebook 14.”

Why is the CB3-431’s June 2022 date decisive?
Google lists June 2022 as the CB3-431’s automatic-update end date in its current Auto Update policy. Google explains that the final automatic update is the point after which ChromeOS and browser updates—including security updates, bug fixes and new features—stop. That makes the CB3-431 a poor choice for a new main computer, even if its purchase price looks attractive.
A Chromebook can still power on after its AUE date, and an already-installed app may open, but there is no continuing official update commitment. Websites can change their security and browser requirements, and unsupported software problems are less likely to have an official fix. Treat any post-AUE use as a limited, risk-accepting scenario rather than as equivalent to a supported Chromebook.
Google’s general policy now describes up to 10 years of automatic updates, measured from a platform’s release date. The policy also notes that some features and services may not be supported for extended-update periods on devices released before 2021. The 10-year statement therefore cannot revive the CB3-431’s already-passed date.

Chromebook Plus is a product category, not a single Acer model or a universal specification sheet. Google introduced the category in 2023 as a higher hardware baseline for faster everyday work and additional software capabilities; the launch announcement is historical context, while the current eligibility page is the authority for today’s requirements.
Google’s current Chromebook Plus OS-update eligibility page specifies, among other requirements:
Also popular on Amazon
- 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.
- At least 8 GB of RAM.
- At least 128 GB of storage.
- A Full HD IPS or better display.
- A 1080p-or-better webcam with Temporal Noise Reduction.
- A processor in the applicable qualifying tier listed by Google.
Those are category and update-eligibility rules, not a promise that every Chromebook Plus laptop has the same CPU, ports, battery capacity, weight or screen aspect ratio. Do not infer that an old Chromebook becomes Plus because it happens to have similar memory or storage. Google names the models that qualify; the CB3-431 is not among the named Acer models on the current eligibility page.
What do we know about the Acer Chromebook Plus 514?
Google’s ChromeOS device catalog lists the Acer Chromebook Plus 514 family with a 14-inch WUXGA display and configurations reaching 16 GB of memory and 512 GB of storage. “Up to” is important: an individual retail SKU may have less memory or storage, so read the complete model number and specification before ordering.
Google’s Auto Update table lists different Chromebook Plus 514 variants through June 2033 or June 2035. The date is assigned to the model family or variant, not simply to the words “Plus 514.” A separate Acer Chromebook Plus CB14 (CB1405CTA) entry is listed through June 2035. Confirm the exact AUE for the configuration you are considering in Google’s policy table.
The official ChromeOS device catalog is useful for identifying model families, but it does not replace the retailer’s SKU page for ports, processor, wireless standard, keyboard layout, weight or included accessories. Those details can change within one family.
How do the two choices compare on the factors that matter?
| Factor | Acer Chromebook 14 CB3-431 | Acer Chromebook Plus 514 | What the difference means |
|---|---|---|---|
| Product status | Legacy Chromebook 14 model | Current Chromebook Plus family | Compare a specific Plus SKU, not the category name alone. |
| Official updates | Listed through June 2022 | Different variants listed through June 2033 or June 2035 | Match the date to the full model number. |
| RAM | Not established by the supplied official sources | Family configurations up to 16 GB; Plus eligibility requires at least 8 GB | Verify the installed amount on the particular listing. |
| Storage | Not established by the supplied official sources | Family configurations up to 512 GB; Plus eligibility requires at least 128 GB | Do not assume the maximum configuration is the one for sale. |
| Display | Exact panel and resolution vary by model information; not established here | Catalog lists a 14-inch WUXGA display for the 514 family; Plus eligibility requires Full HD IPS or better | Check the panel type and resolution for the exact SKU. |
| Webcam | Not established by the supplied official sources | Plus eligibility requires a 1080p-or-better camera with Temporal Noise Reduction | Confirm whether the listing is a qualifying Plus model. |
| Processor, ports, weight and price | Not established by the supplied official sources | Vary by configuration and retailer listing | These require an exact model-number check; no current price is supported here. |
This table deliberately leaves unsupported values blank. A generic “Chromebook 14 versus Chromebook Plus” spec comparison would risk assigning one Acer 14 specification to every CB3-431 or one Plus 514 specification to every configuration.

How do you check a Chromebook’s exact model and support date?
Use this process before buying a used Acer 14 or ordering a Chromebook Plus:
Free tools Windows power users keep installed
One-click scans. No signup required.
- Find the full model code. On a physical Chromebook, check the underside label, original packaging or the device information screen. A listing should identify more than “Acer Chromebook 14” or “Chromebook Plus.”
- Open Google’s update-schedule page. Search the table for the exact code, including suffixes and regional variants. For a used Chromebook 14, verify that it is actually CB3-431 before applying the June 2022 date.
- Read the AUE date, not just the product year. The AUE is the practical cutoff for official ChromeOS and browser security maintenance.
- Check the configuration line by line. Confirm RAM, storage, display resolution and panel, webcam resolution, processor, ports, wireless connectivity and keyboard language. For the Plus 514, make sure “up to 16 GB/512 GB” has not been mistaken for the capacity of the offered unit.
- Compare the date with your planned ownership period. A device with a long remaining support window is usually more sensible as a primary laptop than a cheaper device whose support has already ended.
If Google’s table does not show the exact code, pause the purchase. Ask the seller for a clear model-number photo or use Acer’s documentation to identify the machine; do not substitute a similar-sounding model.
When could a used CB3-431 still make sense?
Only narrow use cases justify considering it: a disposable travel computer, an offline writing machine, a child’s supervised device for a controlled task, or a temporary stopgap priced low enough that the lack of support is fully understood. Even then, avoid entering sensitive passwords, handling financial information or treating it as a secure work computer.
The purchase should be contingent on more than price. Check whether the battery holds a practical charge, the charger is included and safe, the screen and hinges are intact, the keyboard and trackpad work, Wi-Fi connects and the device can be power-washed. A cheap unsupported Chromebook that needs a battery or charger can cost more than a supported entry-level alternative. Those are condition checks, not evidence that the CB3-431 is supported.
Do not buy a CB3-431 on the assumption that installing a newer ChromeOS release will turn it into Chromebook Plus. Google’s Plus eligibility is model- and hardware-specific, and the CB3-431 is not listed among the named Acer models eligible for that OS update.

When is Chromebook Plus the better choice?
Chromebook Plus is the straightforward choice when the laptop will be your everyday browser, school, communication or office computer; when you plan to keep it for several years; or when video calls and local storage matter. The category’s minimums—8 GB RAM, 128 GB storage, Full HD IPS-or-better display and a 1080p camera with Temporal Noise Reduction—address common limitations in older, low-end Chromebooks.
Still, choose by SKU. A lower-memory or smaller-storage configuration can feel very different from the family maximum, and a 2033 AUE is not the same as a 2035 AUE. If two listings are close in price, the longer support date and larger memory/storage configuration may matter more than a small difference in processor branding, provided the processor meets your workload.
What should you verify on a Chromebook Plus 514 listing?
- Full model number and AUE: confirm whether Google assigns the variant June 2033 or June 2035 support.
- Installed memory: distinguish 8 GB, 16 GB or another amount from the family’s “up to 16 GB” statement.
- Storage capacity: verify whether the unit has 128 GB, 256 GB, 512 GB or another listed capacity.
- Screen: check that the listing’s size, WUXGA resolution and panel description match the specific SKU.
- Webcam: confirm the 1080p-or-better camera and Temporal Noise Reduction if Plus features are important to you.
- Processor and ports: these are configuration-level details and are not supplied by the family headline alone.
- Return policy and regional layout: make sure the seller accepts a return if the delivered configuration differs from the listing.
Current prices, inventory and retailer terms were not established by the cited research, so treat any price shown by a shop as a live figure to recheck at checkout rather than as a stable specification.
What are the most common comparison mistakes?
- Comparing a product name with a category. “Acer Chromebook 14” needs a model number, while Chromebook Plus covers multiple devices.
- Using the 10-year policy as a blanket guarantee. Google’s policy is measured from each platform’s release and has qualifications; it does not extend a model past its published AUE.
- Confusing launch material with current eligibility. Google’s 2023 announcement describes the category’s introduction. Use the current eligibility page and Auto Update table for present-day model and support decisions.
- Assuming “up to” is the supplied configuration. The Chromebook Plus 514 family reaches 16 GB and 512 GB, but a particular SKU may not.
- Relying on a seller’s year or condition claim. The AUE table and exact model code are stronger evidence than “new,” “like new” or “2024 model” in a listing.
Which one should you buy?
Buy a specific Acer Chromebook Plus model—such as a verified Chromebook Plus 514 configuration—if you need a supported laptop for current work, school or personal accounts. Confirm its exact AUE, memory, storage, display, webcam and processor before purchase. Consider the CB3-431 only as a cheap, limited, non-sensitive used device, and only after recognizing that Google lists its official updates as ending in June 2022.
If the machine you found is merely labeled “Acer Chromebook 14,” stop and identify its model number first. A different Acer 14 may have a different AUE, so the CB3-431 verdict cannot safely be generalized to every Chromebook carrying that family name.

How we made the choice
The ranking prioritizes official support lifespan, exact model identification, Chromebook Plus eligibility requirements, configuration transparency and suitability as a current primary computer. Google’s Auto Update policy, Chromebook Plus eligibility page and ChromeOS device catalog supply the model and hardware facts; no hands-on performance test or independent benchmark is implied.
Frequently Asked Questions
Can I use an Acer Chromebook 14 CB3-431 after June 2022?
It may still start and run installed software, but Google no longer promises ChromeOS, browser or security updates after the listed AUE. Keep any post-AUE use to low-risk, non-sensitive tasks rather than treating it as a secure daily computer.
Does every Chromebook Plus laptop have a touchscreen or stylus?
No. Chromebook Plus defines baseline hardware and eligible models, not a universal hinge, touchscreen or pen design. Check the exact Acer SKU for those features.

Eight gigabytes meets Google’s stated Plus eligibility minimum. Whether it is sufficient for your tabs, Android or Linux apps depends on the workload, so compare the offered configuration with the family’s optional 16 GB versions.
Why do two Acer Chromebook Plus 514 listings show different support dates?
Google assigns AUE dates to specific model variants, not just the shared 514 name. A listing can therefore correspond to a June 2033 variant while another corresponds to a June 2035 variant; match the complete model number.
