ASUS Chromebook Flip CX5 (CX5400)

Updated on January 26, 2026

The ASUS Chromebook Flip CX5 (CX5400) represents what many consider ASUS’s return to form in the premium Chromebook market. Launched in 2021 with 11th-generation Intel Tiger Lake processors, this 14-inch convertible combines an all-aluminum chassis with a fanless design that has earned it a devoted following among Chrome OS enthusiasts. With support lasting until June 2031, it remains a compelling option for those seeking a premium 2-in-1 experience without the bulk of larger devices. The included USI stylus that stows inside the chassis and recharges automatically addresses one of the most common complaints about stylus-compatible devices: never having the pen when you need it.

Detailed Insights into the ASUS Chromebook Flip CX5 (CX5400)

The design philosophy behind the CX5400 prioritizes build quality above all else, and it shows immediately upon picking up the device. The all-aluminum unibody construction eliminates the flex and creaking that plague many mid-range Chromebooks, delivering what reviewers consistently describe as “Pixelbook Go-level firmness.” ASUS chose beveled edges and a distinctive angular aesthetic that sets it apart from the rounded designs common in the category, weighing in at just over 3 pounds while maintaining structural integrity across all four convertible modes.

The 14-inch Full HD IPS display delivers approximately 330 nits of brightness with excellent viewing angles, making it suitable for both indoor productivity and casual outdoor use. While it falls short of the 400+ nit panels found on some premium competitors, the color accuracy and consistency across the panel satisfy most users. The NanoEdge bezels achieve an 85% screen-to-body ratio, keeping the overall footprint compact despite the generous screen real estate. The touchscreen supports both finger input and the included USI stylus, with the pen garage located on the left side of the chassis where it magnetically snaps into place and automatically charges.

Connectivity options include two Thunderbolt 4 USB-C ports positioned on opposite sides of the device, ensuring convenient access regardless of your workstation setup. The single USB-A 3.2 Gen 1 port accommodates legacy peripherals, while the microSD card slot enables storage expansion for those needing more than the base 128GB NVMe drive. WiFi 6 and Bluetooth 5.0 provide modern wireless connectivity, and the physical camera privacy shutter offers a hardware-level solution for those concerned about webcam security. The 48Wh battery delivers approximately 10 hours of real-world usage, though heavy stylus use or video streaming can reduce this figure.

Reviewer Insights on the ASUS Chromebook Flip CX5 (CX5400)

Chrome Unboxed’s Perspective

Chrome Unboxed’s Robby Payne has been particularly effusive in his praise for the CX5400, declaring it his “everyday carry” device and consistently ranking it among his favorite Chromebooks. In his initial unboxing, he noted that “this is actually the real successor, I feel like, to things like the Flip C302, the C434, and the C436,” emphasizing how the CX5400 corrects the shortcomings of previous ASUS convertibles. The build quality earned his highest compliments, with comparisons to the Pixelbook Go’s legendary rigidity: “This thing feels awesome… This is like Pixelbook Go kind of firmness here.”

In his follow-up review after extended use, Payne doubled down on his enthusiasm, stating “The ASUS Chromebook Flip CX5400 has become my everyday carry.” He particularly praised the input devices, describing the glass trackpad as “absolute butter” and appreciating the visible gray keycaps that maintain legibility even with backlighting active. His one substantive criticism concerned the speakers, which he noted are “not the best in class” compared to the Pixelbook Go, though he found them superior to most other Chromebooks in the category.

Written Review Consensus

Chrome Unboxed’s written review crystallized the overall sentiment: “This thing just oozes quality.” The review emphasized that beyond the impressive specifications, the CX5400 excels through superior integration of its components, creating what the reviewer called “that undefined quality that just makes you truly enjoy using something.” The stowed stylus received particular mention, with the observation that “the best pen is always the one you actually have with you.”

Android Police’s Will Sattelberg offered a more measured perspective in his 7/10 review, praising the “distinctive angular aluminum design with beveled edges” and “responsive, backlit keyboard” while criticizing the 16:9 aspect ratio that “reduces vertical workspace” and questioning whether Chrome OS limitations justify the premium pricing. His review noted trackpad accuracy concerns that some early adopters experienced, though many users report these resolved with software updates.

Customer Reviews of the ASUS Chromebook Flip CX5 (CX5400)

Amazon customers have rated the ASUS Chromebook Flip CX5 (CX5400) 4.1 out of 5 stars based on approximately 90 reviews, reflecting generally positive but not universal satisfaction. The most consistent praise centers on the build quality and fanless operation, with multiple reviewers noting the premium feel compared to similarly-priced Chromebooks and appreciating the completely silent operation during quiet environments like libraries or late-night work sessions.

Several customers highlight the included stylus as a key differentiator, particularly for note-taking and light sketching. The automatic charging when stowed eliminates the frustration of dead stylus batteries at critical moments. However, some reviewers note the stylus experience trails dedicated drawing tablets and may not satisfy serious digital artists. The long Chrome OS support timeline through 2031 appears in multiple positive reviews as a significant value consideration, especially for those planning to use the device for several years.

Criticism typically focuses on three areas: the base model’s 8GB RAM limitation for heavy multitaskers, occasional reports of wake-from-sleep issues that ASUS has addressed through firmware updates, and the premium pricing that some find difficult to justify for Chrome OS. A minority of reviews mention the device running warm during extended use, though the fanless design means this heat dissipation is expected behavior rather than a defect.

Conclusion

The ASUS Chromebook Flip CX5 (CX5400) succeeds as a premium convertible Chromebook by focusing on the details that matter for daily use: exceptional build quality, silent operation, convenient stylus integration, and reliable performance from its 11th-generation Intel processor. While the 16:9 aspect ratio and merely-good speakers represent compromises, the overall package justifies the premium positioning for users who prioritize craftsmanship and longevity over raw specifications. With Chrome OS support extending to June 2031, purchasers today can expect years of productive use from this thoughtfully designed device.
