Mini Bluetooth Wireless Keyboard with 44-Hour Battery Life in Three Screen Sizes

This compact Bluetooth 3.0 wireless keyboard provides a cable-free typing solution for tablets and portable devices, operating reliably within a 10-metre range. It utilises GFSK modulation for stable connectivity and is powered by an integrated 110mAh lithium battery, which delivers a continuous working time of 44 hours on a full charge completed in under two hours. Available in classic black or white finishes, the keyboard is offered in three specific size variants designed to correspond with 7-inch, 9-inch, and 10-inch device screens. With a power-efficient design drawing less than 2.0mA during active use and a standby period exceeding 30 days, it combines practical portability with extended operational readiness. The product’s specifications are clearly stated, including its working temperature range of -10°C to 55°C and a stated lithium battery lifespan of three years.

Features and Construction

The keyboard's functionality is defined by several precise technical parameters and physical specifications that determine its use and compatibility.

Material and Build

The core power component is a 110mAh lithium battery measuring 3.0mm by 25mm by 25mm, which is responsible for the 44-hour continuous working time and over 30 days of standby time. Key actuation is specified at 80±10g of force, providing a measurable tactile response during typing. The construction supports operation within a broad temperature range from -10°C to 55°C, as stated in the source material. Charging current is specified as ≥200mA, leading to the quoted charge completion time of less than two hours.

Size and Practical Fit

A primary practical consideration is selecting the correct size variant for your device. The product is explicitly offered in three options: a 7-inch size, a 9-inch size, and a 10-inch size. This allows for a more tailored fit with different tablet models and screen dimensions. The compact, wireless form factor eliminates cable management issues and supports use within the 10-metre Bluetooth range. The choice between black or white colour finishes offers basic aesthetic customisation to match other peripherals or personal preference.

Uses and Placement

The keyboard’s specifications support its application in various portable and stationary settings where wired alternatives are inconvenient.

Event or Professional Use

The extended 44-hour battery life and month-long standby make it suitable for prolonged use during conferences, trade shows, or off-site presentations where charging opportunities may be limited. Its ability to function in temperatures from -10°C to 55°C adds reliability for use in different environments. The 10-metre wireless range allows the presenter or user to move freely while maintaining control of a connected tablet or device, which can be particularly useful for interactive displays or controlled demonstrations.

Everyday Home Use

For home or office use, the keyboard provides a neat, cable-free desk setup for controlling a media centre tablet, browsing, or light document editing. The three size options mean you can pair it with a specific tablet model, whether a smaller 7-inch device for casual use or a larger 10-inch model for more substantial tasks. The long standby time means the keyboard remains ready for intermittent use throughout the day without frequent charging, and the under-two-hour charge time minimises downtime when power is needed.

Benefits and Buying Value

The value of this product lies in its stated technical performance and the practical advantages derived from its specific specifications.

Reuse and Low Maintenance

The three-year stated lifespan of the internal lithium battery suggests a product designed for extended use without immediate battery replacement concerns. The power-efficient design, with a working current under 2.0mA and a sleep current below 40µA, contributes to the long standby and overall battery longevity. This efficiency reduces the frequency of charging cycles, which can be a practical benefit for users seeking a low-maintenance peripheral that remains ready for use over long periods.

Why Choose This Product

This keyboard presents a clear set of operational parameters: a 10-metre wireless range, 44 hours of continuous use, and compatibility with three common tablet sizes. The choice is informed by these concrete figures rather than unsupported claims. If your primary need is for a compact, wireless typing solution with a known battery performance and a size that matches your 7-inch, 9-inch, or 10-inch device, this product provides those specific, source-supported features. The availability of two colour options allows for basic personalisation within the framework of its technical design.
