The Supernote Manta has a measured footprint of 251.3 mm in height and 182.6 mm in width, with a notably slim 6 mm thickness and a total volume of 275.32 cm³. It weighs 375 g, which is a reasonable figure for a device of its size. The Manta does not feature any weather sealing or splashproofing, so it is not rated for exposure to water or moisture.
The Supernote Manta uses a 10.7″ e-paper display with a resolution of 1920 x 2560 pixels and a pixel density of 300 ppi, delivering fine detail across its screen. The display is self-lit, meaning it has a built-in front light for use in low-light conditions, and it supports touch input for direct on-screen interaction. An anti-reflection coating is applied to the screen surface to reduce glare, though the device does not include branded damage-resistant glass.
The Supernote Manta is powered by a quad-core processor running at 4 x 1.8 GHz and paired with 4GB of RAM to handle its processing workload. It comes with 32GB of internal storage and includes an external memory slot that supports up to 2000GB of additional storage, providing considerable room for documents and files.
The Supernote Manta supports wireless connectivity through Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), along with Bluetooth 5 for short-range wireless connections. It also includes a built-in browser for web access. The device does not feature a cellular module, NFC, or an HDMI output.
The Supernote Manta houses a 3600 mAh rechargeable battery that charges via USB Type-C, and it includes a battery level indicator so users can monitor remaining charge at a glance. The battery is not removable, and the device does not support fast charging or wireless charging.
The Supernote Manta includes a built-in dictionary, text-to-speech support, and compatibility with 10 different file types, making it reasonably versatile for reading and document handling. It features a built-in HDR mode, a child lock, an accelerometer, and a gyroscope for motion sensing. On the other hand, it does not include a built-in speaker, a 3.5 mm headset jack, GPS, a compass, a radio, or a front camera.
