Mini Bluetooth Wireless Keyboard with 44-Hour Battery Life and 10-Metre Range for Tablets

This mini Bluetooth wireless keyboard addresses the common challenge of efficient text entry on tablets and smartphones by providing a dedicated typing solution without the bulk of full-sized alternatives. With Bluetooth 3.0 connectivity utilising GFSK modulation, it establishes a stable wireless connection to your mobile device, allowing you to type comfortably while maintaining the portability of your setup. The keyboard delivers 44 hours of sustained working time from its integrated 110mAh lithium battery, which recharges in under 2 hours, alongside an extended standby period exceeding 30 days between uses. Available in both classic black and clean white finishes, it is offered in specific variants designed to complement 7-inch, 9-inch or 10-inch screens, providing a tailored fit for different device sizes.

Technical Specifications and Performance

The keyboard's performance is defined by several key technical parameters that determine its real-world usability. It operates on a voltage range of 1.8 to 3.6 volts, maintaining power efficiency with a working current under 2.0mA during active typing sessions. When not in use, it enters low-power states with standby current between 0.3 and 0.5mA and sleep current below 40μA, contributing to its lengthy battery performance. These electrical characteristics combine with the physical components to create a functional peripheral suited for mobile computing needs.

Bluetooth Connectivity and Range

The keyboard employs Bluetooth 3.0 technology with GFSK (Gaussian Frequency-Shift Keying) modulation, a standard wireless protocol that ensures reliable data transmission between the keyboard and your paired device. This implementation provides an effective operational range of 10 metres, allowing you to position the keyboard conveniently while maintaining connection integrity. The 10-metre distance accommodates various usage scenarios, from couch-based tablet typing to presentation setups where the keyboard can be placed at a comfortable distance from the screen.

Battery System and Power Management

Powering the keyboard is a 110mAh lithium battery measuring 3.0 x 25 x 25mm, which delivers the stated 44 hours of continuous operation on a full charge. This battery features a specified lifespan of 3 years under normal usage conditions and recharges in under 2 hours using a compatible charging source. The system's power management combines this battery capacity with efficient circuitry that minimises consumption during active use and implements aggressive power-saving during idle periods, resulting in the extended standby time exceeding 30 days.

Physical Build and Environmental Tolerance

The keyboard's keys require 80±10g of actuation force, providing tactile feedback during typing without excessive pressure. This specification indicates a balanced key mechanism designed for regular use without fatiguing the fingers during extended typing sessions. The unit is engineered to function across a temperature range from -10 to 55 degrees Celsius, accommodating various indoor environments and occasional transport between locations with different ambient conditions.

Selection and Compatibility

Choosing the appropriate variant of this mini Bluetooth keyboard involves matching it to your primary mobile device's screen size for optimal pairing. The keyboard is manufactured in three distinct size configurations specifically intended for use with 7-inch, 9-inch and 10-inch tablets and smartphones. This sizing approach ensures proportional compatibility between the keyboard dimensions and your device's form factor, creating a more coherent mobile computing setup.

Colour Options and Aesthetic Choice

Two colour variants—black and white—offer basic aesthetic alignment with different device finishes and personal preferences. The black option presents a traditional, understated appearance that matches many professional and consumer electronics, while the white variant provides a cleaner, brighter alternative suited to lighter-coloured devices or contemporary interiors. Both finishes maintain visual simplicity without decorative elements that might distract from practical use.

Device Pairing and Setup

Pairing the keyboard with your tablet or smartphone follows standard Bluetooth connection procedures, requiring activation of Bluetooth on your mobile device and putting the keyboard into pairing mode. Once connected, the keyboard maintains this pairing for subsequent uses, automatically reconnecting when powered on within range. The Bluetooth 3.0 implementation ensures compatibility with most modern tablets and smartphones manufactured within the technology's supported period.

Mobile Typing Scenarios

The keyboard's compact dimensions and wireless operation suit various mobile computing situations where tablet or smartphone typing would otherwise be limited to on-screen keyboards. These scenarios include extended document creation, email composition, data entry tasks, educational note-taking, and content creation activities that benefit from physical key feedback. The 10-metre range particularly supports presentation environments where the presenter might move while maintaining keyboard control of their device.

Practical Value and Usage Benefits

The practical value of this mini Bluetooth keyboard lies in its specific combination of portability, battery efficiency, and reliable connectivity. By providing dedicated physical keys for tablet and smartphone interaction, it addresses the ergonomic limitations of prolonged on-screen typing while maintaining the mobility advantages of smaller devices. The extended battery performance reduces charging frequency concerns during regular use, and the straightforward design focuses on core functionality rather than specialised features that might complicate operation.

Reduced Charging Frequency

With 44 hours of continuous operation from a single charge and standby exceeding 30 days, the keyboard significantly reduces the need for frequent charging compared to peripherals with shorter battery life. This endurance supports extended use during travel, work sessions, or educational settings without requiring constant access to power sources. The under-2-hour recharge time further minimises downtime when charging does become necessary.

Portability and Space Efficiency

The mini form factor preserves the inherent portability of tablets and smartphones while adding dedicated typing capability. Unlike full-sized keyboards that demand substantial carrying space, this compact design fits easily into bags, cases, or alongside devices without adding noticeable bulk. This space efficiency makes it practical for mobile professionals, students, or casual users who value both typing convenience and easy transport between locations.

Why This Keyboard Suits Mobile Users

This keyboard suits mobile users because it addresses the specific constraints of tablet and smartphone text entry without compromising device portability. The 10-metre Bluetooth range provides placement flexibility in various environments, while the extended battery life accommodates unpredictable access to charging during mobile use. By offering size variants matched to common screen dimensions, it ensures proportional compatibility rather than a one-size-fits-all approach that might not integrate well with all devices.
