Mini Bluetooth Wireless Keyboard with 44-Hour Battery Life for 7, 9, and 10-Inch Tablets

This compact Bluetooth wireless keyboard provides a practical typing interface for tablets and smartphones, eliminating the need to rely solely on touchscreens. It connects seamlessly via Bluetooth 3.0 technology, offering a stable link within a 10-metre radius, allowing you to type from a comfortable distance. Designed for portability, it is available in black or white to suit your device's aesthetics and is proportioned for use with 7-inch, 9-inch, or 10-inch screens. Its core advantage lies in a substantial 44 hours of continuous working time, supported by an integrated 110mAh lithium battery that recharges in under two hours, making it a reliable accessory for extended use without frequent power interruptions.

Features and Construction

The keyboard is built around its wireless functionality and power system, engineered for efficiency and compatibility with common mobile devices.

Material and Build

At the heart of the keyboard's operation is a 3.0 x 25 x 25 mm lithium battery, which delivers the stated 110mAh capacity. This battery supports the quoted performance metrics, including the 44-hour continuous runtime and over 30 days of standby time. The keyboard utilises GFSK (Gaussian Frequency-Shift Keying) modulation for its Bluetooth 3.0 connection, a standard method for reliable, low-power data transmission. Keys are designed with an actuation force of 80±10 grams, providing a defined press feel during typing.

Size and Practical Fit

The product is described as a 'mini' keyboard, indicating a compact form factor. It is offered in size variants explicitly matched to 7-inch, 9-inch, or 10-inch device screens, suggesting its physical dimensions are scaled appropriately for use with these common tablet sizes. This fit ensures the keyboard remains portable and usable without dominating your workspace. The available colour choices of black and white offer straightforward options to coordinate with most tech accessories.

Uses and Placement

The 10-metre wireless range and extended battery life open up several practical applications, from casual home use to more mobile scenarios.

Event or Professional Use

The combination of long battery life and a 10-metre operational range makes this keyboard suitable for presentations or controlled environments where you may need to type or navigate from a distance. Its compatibility with various tablet sizes means it can serve as a discreet input device for note-taking during meetings or for operating a device connected to a display. The standby time exceeding 30 days also means it can be left in a bag or desk drawer as a ready-to-go peripheral without constant charging.

Everyday Home Use

For everyday tasks, the keyboard offers a more tactile alternative to on-screen typing for writing emails, composing messages, or browsing the web on your tablet. The effective 10-metre range allows for use from a sofa or bed while the tablet rests on a table or charger. Choosing the size variant (7, 9, or 10 inches) that matches your primary tablet ensures a balanced and practical pairing for daily entertainment or light productivity tasks.

Benefits and Buying Value

The value of this keyboard stems from its quantified performance parameters, which provide clear expectations for its operation and maintenance.

Reuse and Low Maintenance

The source states a lithium battery life of three years, indicating the expected functional lifespan of the power cell under normal use. With a 44-hour working time per charge and a quick sub-two-hour recharge cycle, the keyboard requires minimal daily power management. The very low sleep current (under 40μA) and standby current (0.3-0.5mA) contribute to preserving charge when not actively in use, enhancing its readiness and reducing energy waste.

Why Choose This Product

This keyboard presents a clear, specification-driven choice for users seeking a wireless typing solution with defined parameters. Its value is anchored in the provided 44-hour runtime, 10-metre range, and explicit compatibility with three common tablet size categories. Unlike products with vague claims, its specifications for working voltage (1.8-3.6V), current draw, and operating temperature range are stated, allowing for informed use. The simple black and white colour options and straightforward size selection remove guesswork from the purchasing decision.
