ASUS Chromebook CM30 Detachable

Published on May 17, 2026

The ASUS Chromebook CM30 Detachable arrives as a complete ChromeOS package rather than a tablet that asks you to buy accessories one at a time. ASUS bundles the 10.5-inch WUXGA touchscreen, a magnetic keyboard folio with a kickstand, and a garaged USI 2.0 stylus, all running on the fanless MediaTek Kompanio 520 platform. The chassis is metal, the display reaches 400 nits, and the device promises roughly twelve hours of mixed use thanks to its ARM-based silicon. Updates are guaranteed through June 2033, which gives this CM3001 generation about seven years of runway before it ages out of ChromeOS. The result is a budget detachable aimed at students, casual creators, and anyone who wants something lighter than a Chromebook Plus laptop without giving up a real keyboard.

ASUS borrowed liberally from the Lenovo Duet template here, but the company added refinements that genuinely matter day to day. The keyboard folio uses magnets to align the kickstand and snaps the tablet into place far more confidently than older Duet covers, and the keys offer 1.5mm of travel that reviewers consistently describe as surprisingly substantial. The garaged stylus charges inside the body and stays out of your way until you need it, and dual 5MP cameras front and back handle video calls and quick document scans. The trade-off, of course, is the processor: this is a tier below the Kompanio 1380 or Snapdragon-class silicon you find in newer ChromeOS tablets, so heavy multitasking will surface its limits.

Detailed Insights into the ASUS Chromebook CM30 Detachable

The CM30 tablet measures 10.22 by 6.66 by 0.35 inches and weighs about 1.34 pounds on its own; clip the keyboard folio in and the bundle lands close to two pounds, which is still lighter than nearly any clamshell Chromebook. ASUS uses an aluminum back and a soft-touch folio that reviewers describe as feeling closer to a premium tablet than a $300 device has any right to. The only physical port is a single USB-C that handles power, data, and DisplayPort output, alongside the combo headphone jack on the tablet edge. There is no microSD slot on the US CM3001 SKU despite what a few third-party reviews claim, and no HDMI of any kind: external displays require a USB-C hub.

Performance comes from the MediaTek Kompanio 520, an eight-core ARM processor running at 2.0 GHz with an Octane score around 25,000. That is enough headroom for the productivity work ChromeOS is built around: a dozen Chrome tabs, Google Docs, Gmail, and a streaming video on the side. Push beyond that and the limits show, particularly when you try to play 4K@60fps YouTube content (where the CM30 drops frames) or run heavier Android games. The processor is fanless and stays cool under typical workloads, which is part of why battery life lands where it does.

Wireless connectivity covers WiFi 6 (802.11ax) and Bluetooth 5.4, which is generous for the price point and meaningfully better than the WiFi 5 you still find on some entry-level ChromeOS tablets. There is no cellular option on this SKU. Both cameras are 5MP, with the world-facing sensor positioned for quick document capture and the front-facing camera intended primarily for video calls; ASUS includes a 45W charger in the box, which is overkill for this device but useful if you charge other USB-C accessories alongside it. Storage is 128GB of soldered eMMC with no upgrade path; if you need more capacity, you will be leaning on Google Drive or an external USB-C drive.

Reviewer Insights on the ASUS Chromebook CM30 Detachable

Lon Seidman of Lon.TV framed the CM30 as the rare ChromeOS tablet whose total package undercuts a base iPad. “The price that you’ll pay for this device with the keyboard the tablet and a garage pen here at the top is less than what you would spend on a new entry-level iPad on its own,” he said in his review. Lon spent the bulk of his testing on real-world tasks, noting accurate trackpad behavior and a keyboard with surprisingly long 1.5mm key travel. He also called out the dated bezels and the keyboard folio’s tendency to slip around when closed (there are no magnets holding the closed state together), but his overall verdict was that the bundle adds up to a strong value if you set your performance expectations correctly.

Android Digest reached a similar conclusion after a 15-minute hands-on. The reviewer emphasized the included accessories and the 400-nit display, observing that “the battery life is very very good on this tablet… easily last over 10 hours and you might even get 12 or more depending on what you’re doing.” They acknowledged that the Kompanio 520 is a step behind the silicon in the Lenovo Duet 3 and Duet 5, but argued that “if it does go on sale… it’s actually going to be a good buy.” Their critique focused on the tinny speakers, the lone USB-C port, and the base 4GB RAM SKU, which they considered too cramped for ChromeOS.

Chrome Unboxed’s CES 2024 hands-on zeroed in on the build quality, which represents a major step up from the original CM3. “The whole thing just it feels really really well made and premium which is kind of wild for these tablets,” the reviewer said, contrasting the new magnetic alignment system with the looser fit on older detachable Chromebooks. They praised the keyboard’s 1.5mm travel and the headphone jack, but warned about brightness shift at off-angles and “weak, tinny speakers with no bass” that are easy to cover when you hold the tablet by its long edge. Their final read was a pre-production unit destined for budget shelves, not a flagship contender, and they were clear that “this won’t be the fastest tablet out there the day it launches; it’s just not the market for this thing.”

Across the three high-quality reviews, the consensus is consistent: premium build, useful accessory bundle, and long battery life on one side; modest performance, a single USB-C port, and underwhelming speakers on the other. None of the reviewers recommended the CM30 for heavy multitaskers or anyone planning to push ChromeOS toward demanding Android games, but all of them saw real value in the bundle for everyday use.

Customer Reviews of the ASUS Chromebook CM30 Detachable

Across 13 ratings on Amazon, the ASUS Chromebook CM30 Detachable averages 4.5 stars, with about 80% of reviewers leaving five stars and a couple of lower marks. The recurring praise is for the keyboard and the portable detachable form factor. Katherine K., a verified buyer who wanted something between a phone and a full laptop, wrote “This little chromebook is PERFECT. The keyboard is solid and responsive,” and noted the integrated pen meant she did not need a mouse. Another verified buyer was happy with the build and value but flagged a real limitation: “The processor speed is a little slow at times.” Katherine K. raised the other common gripe, the single port: “Because all it has is a charger port.”

The picture is not uniformly glowing. A verified reviewer using the handle AutomaticFailure left three stars after sending it back, writing “Returned, overall the product was great, just not the right fit.” With only 13 ratings the sample is small, so treat the averages as an early read rather than a settled verdict.

Who Should Consider the ASUS Chromebook CM30 Detachable

The CM30 fits best for buyers who want a true tablet experience with a real keyboard, not a clamshell that flips over backwards. It works for students who need a portable device for note-taking with the stylus and typing in Google Docs, for travelers who value the under-two-pound footprint, and for casual buyers who would otherwise consider an entry-level iPad but want ChromeOS and a bundled keyboard. The seven years of remaining update support are a real benefit in the budget tier, where many ARM Chromebooks reach end-of-life much sooner.

Buyers who need a touchscreen Chromebook with more performance or who plan to lean on heavy Android apps will be happier with a Kompanio 1380 or Snapdragon-based ChromeOS tablet. Anyone who works with two external displays, a wired ethernet connection, or large local files will hit the CM30’s single-port and eMMC limits quickly. And users who write in low light should look at one of the backlit-keyboard Chromebooks instead, since this folio omits keyboard illumination.
