For field engineers and minimalist enthusiasts, the search for a truly capable, palm-sized computer often ends in disappointment. Most ultra-compact devices trade performance for size, leaving users with underpowered chips that struggle with modern multitasking. Tenku, a Japanese brand known for its specialized form-factor PCs, is attempting to bridge that gap with the new Note Pro AI, a 10.5-inch machine that refuses to compromise on the internal architecture.
At the heart of this device lies an Intel Core Ultra 5 125U processor. This Meteor Lake chip brings a 12-core configuration to the table - consisting of two performance cores, eight efficiency cores, and two low-power efficiency cores - alongside a dedicated NPU for AI-accelerated tasks. It is a significant leap for a device that weighs just 960 grams (2.1 lbs) and occupies a footprint smaller than a standard sheet of paper.
Engineering for the Field
The Note Pro AI is designed with portability as the primary directive. With dimensions of 243 x 177.6 x 17.5 mm, the aluminum-clad chassis is built to be tossed into a gear bag without a second thought. The 10.51-inch IPS display features a 1920 x 1280 resolution, resulting in a sharp 219 PPI that makes text and technical schematics easy to read despite the small size. Furthermore, the 10-point touch screen supports an active stylus with 4,096 levels of pressure sensitivity, a critical feature for technicians who need to annotate diagrams or sign documents on the go.
The hardware flexibility extends beyond the screen. While the 16 GB of LPDDR5 RAM is soldered, the device includes an M.2 2280 slot, providing a clear path for storage upgrades beyond the base 512 GB SSD. This is a welcome touch in an era where ultra-compact laptops are often entirely sealed shut, limiting the longevity of the machine.
Connectivity and Performance Trade-offs
Space constraints inevitably lead to trade-offs, and the Note Pro AI is no exception. The I/O selection is sparse, offering only two USB 3.1 Type-C ports, a 3.5 mm headphone jack, and standard wireless connectivity via Wi-Fi 6 and Bluetooth 5.2. However, the USB-C ports support both DisplayPort output and power delivery, meaning a single cable can connect the laptop to a full-sized monitor and power supply in a desk setup.
Performance-wise, the 15W Core Ultra 5 chip positions this machine as a capable daily driver for specialized workflows. It holds its own against the AMD Ryzen 5 8540U, making it more than sufficient for coding, data entry, and field diagnostics. The 8,000 mAh battery is designed to keep the power-efficient Meteor Lake architecture running through a standard workday, provided the workload remains within the bounds of typical office and administrative tasks.
Pricing and Availability
The Tenku Note Pro AI is currently retailing in Japan for approximately $953 (¥150,280). As of now, the device is primarily available through Japanese online platforms. While a broad international release has not been confirmed, global enthusiasts can typically source these units through import services. For those who prioritize screen real estate over extreme portability, larger alternatives like the Lenovo IdeaPad Slim 5X remain more accessible at lower price points, but for the specific niche of ultra-micro computing, Tenku remains one of the few brands still pushing the boundaries of what a 10-inch form factor can achieve.
