Manual of product B3-A42-K74M
Editorial note
The Acer B3-A42-K74M tablet stands out with its 10.1-inch screen offering a resolution of 1280 x 800 pixels, ensuring a pleasant visual experience thanks to IPS technology and LED backlighting. The Mediatek MT8735 quad-core processor allows for smooth performance for everyday tasks, although the 2 GB of RAM may limit multitasking, leading to slowdowns when running multiple applications simultaneously. The 6100 mAh battery is a major asset, with a battery life of up to 9 hours, ideal for prolonged use without interruption. The tablet's modern and practical design, while elegant with its white color, may be prone to dirt. However, there are some drawbacks to consider. The 16 GB of internal storage may prove insufficient for users wishing to keep many files or applications, often requiring the use of a memory card. Additionally, the Android 7.0 operating system, while functional, is relatively old, which could limit access to the latest applications and security updates. Finally, the lack of HDMI ports restricts connectivity options, which can be a disadvantage for those wanting to project their screen onto a TV or monitor. Overall, the value for money is fair, but it would suit users with moderate needs who prioritize portability and battery life.Score details
