The Portronics Bubble 3.0 is a full-sized, sleek, and highly versatile wireless keyboard designed to seamlessly bridge the gap between multiple devices on your desk.

Key Features

• Quad Connectivity (Bluetooth 5.3 + 2.4 GHz): Pair with up to four devices simultaneously. It supports three distinct Bluetooth 5.3 channels and one ultra-stable 2.4 GHz wireless connection via the included USB nano receiver. You can toggle between your PC, tablet, and phone instantly using dedicated hotkeys.

• Integrated Device Slot: Features a built-in, silicone-padded cradle at the top of the keyboard. This slot safely props up smartphones or tablets at an optimal viewing angle right in front of you, turning mobile devices into mini workstations without scratching them.

• Built-in Rechargeable Battery: Say goodbye to constantly swapping out AAA batteries. The Bubble 3.0 houses an eco-friendly 500 mAh rechargeable battery that juices up quickly via a modern Type-C port, lasting for days of uninterrupted workflow on a single charge.

• Full-Size Layout with Integrated Numpad: Unlike cramped travel keyboards, this features a complete layout with a dedicated numeric pad—essential for data entry, finance tasks, and calculations.

• Ergonomic Dual Height Adjustment: Built with flip-out feet underneath, allowing you to choose between two distinct typing angles. This slight elevation minimizes wrist extension and reduces fatigue during long typing sessions.

• Silent X-Structure Keys: Equipped with low-profile, concave keycaps backed by a scissor-switch mechanism (X-structure). This balances every keystroke to provide tactile feedback while operating almost completely silently—ideal for quiet offices or late-night remote work.

• Multimedia Hotkeys & AI Integration: Includes intuitive quick-access shortcuts for volume adjustments, media playback, and system controls. It also features a dedicated Microsoft Copilot key for instant, one-tap access to AI assistant features on compatible systems.
