Ultra-thin Tri-fold Folding Touch Bluetooth Keyboard for iPhone, Android & Microsoft Devices

This portable tri-fold folding touch keyboard provides a space-saving typing solution for users who need to work across Apple iOS, Android, and Microsoft Windows platforms. Its primary advantage lies in its compact, ultra-thin form factor, which folds down to dimensions of 302 millimetres by 97 millimetres by 18 millimetres for easy transport in bags or cases. When unfolded for use, it presents a spread size of 152mm by 97mm by 18mm, offering a full keyboard layout alongside an integrated touchpad. The product connects wirelessly via Bluetooth 3.0 technology, eliminating cable clutter and supporting a range of modern smartphones, tablets, and laptops. Available in both black and silvery white finishes, with some options configured with Spanish keyboard layouts, it caters to international users seeking a versatile, portable input device.
Features and Construction

The keyboard's design centres on portability and cross-platform compatibility, incorporating specific hardware to support mobile and desktop operating systems.
Material and Build
Powering the keyboard is a built-in rechargeable lithium battery with a 140mAh capacity. This battery type is commonly used in portable electronics for its energy density and recharge cycle life. The keyboard itself utilises an ultra-thin construction that contributes to its folded profile of 18mm in depth. The inclusion of a touchpad measuring 54.8mm by 44.8mm is integrated into the chassis, providing a pointing device without adding bulk or requiring separate peripherals. The product's construction enables it to fold twice into a compact shape, a design choice aimed at reducing its storage footprint.
Size and Practical Fit
The keyboard's dimensions are clearly defined for both operational and transport states. In its opened, ready-to-use form, it measures 152mm in width, 97mm in depth, and 18mm in height. When folded for portability, its width doubles to 302mm, while its depth and height remain at 97mm and 18mm respectively. These measurements allow users to assess how it will fit into laptop sleeves, backpacks, or briefcases. The touchpad's specified size of 54.8x44.8mm offers a practical area for cursor navigation, proportionate to the keyboard's overall compact form. The ultra-thin 18mm profile, maintained in both states, supports its description as a low-profile accessory.
Uses and Placement

Designed for versatility, this keyboard suits various scenarios where a compact, wired-free input device is beneficial, from professional travel to casual home computing.
Event or Professional Use
The keyboard's compatibility with Apple, Android, and Microsoft systems makes it suitable for professionals who use multiple devices across different platforms, such as presenters, sales personnel, or IT support staff. Its 100-hour continuous battery life, supported by the 140mAh cell, reduces the need for frequent recharging during conferences, trade shows, or client meetings. The Bluetooth 3.0 connectivity allows quick switching between a smartphone, tablet, and a laptop without physical connections. The tri-fold design and resulting 302x97x18mm folded size enable it to be packed alongside a tablet or small laptop as a complete mobile office setup. The availability of a Spanish layout option further supports its use in international business or educational contexts.
Everyday Home Use
At home, the keyboard can serve as a secondary input device for a media centre PC, a gaming console, or a family tablet, thanks to its multi-system support. Its ultra-thin profile and compact folded size make it easy to store in a drawer or on a shelf when not in use, avoiding desk clutter. The integrated touchpad can replace a separate mouse for basic navigation on a smart TV or home entertainment system. The under two-hour charging time means it can be conveniently topped up between uses. For households with multiple device types—an iPhone, an Android tablet, and a Windows laptop—this single keyboard can serve all, reducing the need for several dedicated peripherals.
Benefits and Buying Value

The product's value stems from its specific combination of portability, compatibility, and integrated features, which address common needs for a versatile, travel-friendly keyboard.
Reuse and Low Maintenance
The built-in rechargeable lithium battery supports repeated use cycles, with the stated 100-hour runtime minimising daily charging interventions. The Bluetooth connection eliminates wear and tear on physical ports that can occur with plug-in keyboards. Its compatibility across three major operating systems—Apple iOS, Android, and Microsoft Windows—extends its usable lifespan, as it remains functional even if the user changes their primary device ecosystem. The sturdy folding mechanism is designed for repeated opening and closing, a necessary feature for a portable product. Minimal maintenance is required beyond occasional cleaning of the keys and touchpad surface, and ensuring the battery is charged periodically.
Why Choose This Product
This keyboard is chosen for its clear, measurable differentiators: its tri-fold design that achieves a specific folded size of 302x97x18mm, its inclusion of a 54.8x44.8mm touchpad within that footprint, and its verified compatibility with three distinct operating systems. The 140mAh battery capacity and 100-hour use time provide a concrete performance metric for battery life. The availability in both black and silvery white colours, plus Spanish layout options, offers aesthetic and functional choice. It solves the practical problem of carrying a keyboard and mouse separately by integrating both into one ultra-thin unit. For users searching for a 'portable Bluetooth keyboard with touchpad for multiple devices', its specifications directly match that intent.
