Lenovo Chromebook Duet EDU G2 10.9" 83HJ0009UB Luna Gray 2025

The Lenovo Chromebook Duet EDU G2 is a lightweight ChromeOS tablet with best-in-class battery life and a bright 10.9-inch display. But the MediaTek Kompanio 838 processor is one of the slowest we've tested, and 64GB of storage fills up fast. At USD 320 it's a decent student companion; at USD 500 or the higher EUR prices, you're overpaying. Buy it for battery and portability, not for performance.

The MediaTek Kompanio 838 is an 8-core ARM processor, and while the marketing copy loves to throw around words like "lavish" and "exceptional," the benchmarks tell a different story. In our database, this chip sits near the bottom of the pack for CPU performance, in the 5th percentile. That means it's slower than 95% of the processors in comparable devices. For everyday ChromeOS tasks like web browsing, Google Docs, and streaming video, it's adequate. But open more than a handful of tabs or try to run Android apps alongside a video call, and you'll start to see stutters and lag.

The 8GB of LPDDR4X RAM is actually a bright spot here. It's in the 67th percentile, which is solid for a budget Chromebook. That extra memory helps smooth over some of the CPU's limitations, especially when you're juggling multiple browser tabs or running a few lightweight Android apps. The 64GB of eMMC storage, on the other hand, is a weak point. It's in the 30th percentile, and eMMC is noticeably slower than the NVMe SSDs you'll find in pricier machines. ChromeOS is designed to lean on cloud storage, so 64GB is workable if you're disciplined about what you keep locally. But if you like downloading movies for offline viewing or installing lots of Android apps, you'll hit that ceiling fast.

The Duet EDU G2 sits in an awkward spot. It's not competing with the Apple iPad Pro M4 or the Samsung Galaxy Tab S11, both of which are in a completely different performance class. The iPad Pro's M4 chip would run circles around the Kompanio 838, and the Galaxy Tab S11 offers a far more polished tablet experience with better app support. But those devices also cost significantly more. The Duet's real competition is other budget ChromeOS tablets and entry-level Android tablets.

The Microsoft Surface Pro 11th Edition is an interesting comparison. It's a Windows machine with far more capability, but it's also heavier and pricier. If you need full desktop apps, the Surface is the obvious choice. The Xiaomi Pad 62779 is closer in spirit to the Duet, but Xiaomi's Android skin and app ecosystem don't offer the same simplicity as ChromeOS. And the VekfulPC T60 Pro is a wildcard, a lesser-known brand that's hard to recommend without a stronger track record. For pure web-based work and media consumption, the Duet holds its own. For anything else, you'll want to look upmarket.

Pricing on this thing is all over the map, and that's worth paying attention to. In the US, you'll find it listed between USD 320 and USD 500 across three listings. That's a USD 180 spread for the same device, which is wild. If you're shopping in the US, do yourself a favor and hunt for the lower end of that range. At USD 320, this is a compelling budget tablet for students and casual users. At USD 500, you're getting into territory where better options start to appear.

In Europe, the spread is even more dramatic. EUR prices range from EUR 594 to EUR 1,349 across four listings in Germany, Spain, France, and Italy. That EUR 755 gap is hard to justify for a device with a budget ARM chip and 64GB of storage. If you're in the EU, the EUR 594 price is the only one that makes sense. Anything above that, and you're paying a premium for availability rather than performance. The GBP 547 listing in the UK sits somewhere in the middle, but without more context on what's included, it's hard to call it a deal.

The Lenovo Chromebook Duet EDU G2 is one of those devices that makes you stop and think about what you actually need a computer for. It's a 10.9-inch tablet with a detachable keyboard, a MediaTek Kompanio 838 processor, 8GB of RAM, and 64GB of eMMC storage. On paper, that's not going to set any speed records. But the Duet line has always been about portability and battery life, and this one leans hard into that. The EDU in the name tells you who Lenovo is aiming at: students, classrooms, and anyone who wants a lightweight ChromeOS machine for notes, reading, and web work.

What makes this interesting is the battery. Our database puts it in the 96th percentile for battery life among similar devices, which is genuinely impressive for a tablet this thin and light. At 805 grams with the keyboard attached, it's easy to toss in a bag and forget about. The 400-nit IPS display is bright enough for most indoor use, and the 1920x1200 resolution means text looks crisp. Stylus support is a nice bonus for note-takers and doodlers.

But let's be real about the trade-offs. The Kompanio 838 is a budget ARM chip, and it lands in the 5th percentile for CPU performance in our rankings. The GPU is even lower, at the 7th percentile. This is not a machine for video editing, heavy multitasking, or anything that requires real processing power. It's a Chromebook in tablet form, and it behaves like one. If your workflow lives in a browser, you'll be fine. If you need more, you'll feel the ceiling pretty quickly.

If you need to run desktop-class applications, this is not your machine. The Kompanio 838's CPU and GPU performance are near the bottom of our rankings, which means anything beyond web browsing and light Android apps will feel sluggish. Video editors, programmers, and anyone who needs to run Windows or macOS software should look elsewhere. A used Surface Pro or a mid-range Windows laptop would serve you far better.

Also skip this if you're a heavy media consumer who likes to download content. The 64GB of eMMC storage fills up fast, and the lack of expandable storage makes it a constant juggling act. If you want a tablet for offline movies and games, an iPad or a Samsung Galaxy Tab with more storage is a better fit. And if you're shopping in Europe and seeing prices above EUR 700, walk away. This device is not worth that kind of money.

If you're a student who lives in Google Docs, Gmail, and YouTube, the Duet EDU G2 is a solid pick, especially if you can find it at the lower end of the price range. The battery life alone is a huge selling point. You can leave the charger at home and get through a full day of classes without breaking a sweat. The keyboard is decent for note-taking, and the stylus support means you can annotate PDFs or sketch out ideas without much friction.

But if your workload involves anything beyond browser-based tasks, this is not the device for you. The CPU and GPU are simply too weak for photo editing, video work, or even heavy multitasking. And the 64GB of storage will feel restrictive if you're used to downloading content for offline use. For casual users, it's a charming little machine. For power users, it's a frustrating one.
