Compared to laptops, Chromebooks are made for web-based tasks and excel in it in term of productivity. This new Chromebook is simple and the stylish exterior makes it look stunning in terms of its design and it can easily fit in backpacks. The simplicity of the Acer Chromebook R13 CB5-312T-K0YK enables its user to not worry about its configurations as it can be easily set up without needing much of a technical know-how. This particular Chromebook uses a Mediatek MT8173C processor, 4096 MB of RAM and 32 GB eMMC flash memory. The R13 CB5-312T-K0YK comes with a 13.3-inch display with a resolution of 1,920 x 1,080 pixels, a pixel density of 157 PPI, an aspect ratio of 16:9. It supports 10-point input and an active stylus. The Chromebook uses the PowerVR GX6250 graphics with a core clock of 700 MHz for handling all your daily needs while browsing the web.

At 1.5 kg (3.31 lb) and 32.77 x 22.86 x 1.8 cm (12.9 x 9 x 0.71 inch), the Acer Chromebook 13 is a good choice for a lightweight laptop that can last all day without recharging. Compared to typical Chromebooks, the battery life is longest. The battery runtime is the best feature offered by this particular Chromebook. The casing is made from metal and matte white plastic and is refreshingly minimalist. The aluminum use on the Chromebook does not affect the robustness. The Acer and Google Chrome logos are located on the left side of the lid. The tapered bottom contributes to a sleek look. The base unit can be dented. Even when pressure is applied to the lid, it is not easy to break. Towards the front, on the left and right of the of the computer the speaker’s ports are located.
