Satechi launches the ultra-slim EX1 and EX3 keyboards with easily replaceable modular batteries.

At CES 2026, Satechi officially introduced the EX1 and EX3 ultra-thin keyboards along with a new aluminum mouse. The biggest breakthrough in this launch is the modular battery solution, a rare feature on ultra-thin accessories, allowing users to maintain and replace the battery with just a few simple steps.

Ultra-slim design combined with flexible maintenance options.

Currently, ultra-slim keyboards on the market often face challenges in replacing components due to their tight, unibody design. However, with the EX1 and EX3, Satechi has proven that slimness doesn't necessarily come at the expense of repairability. The new modular battery system allows for quick removal and installation, enabling users to proactively replace the battery when performance degrades instead of having to replace the entire device.

Besides the ability to replace batteries, this keyboard duo also boasts a minimalist and sophisticated design language, suitable for many modern workspaces. The use of aluminum not only provides a premium look but also ensures durability during daily use.

Cross-platform connectivity and productivity.

In terms of compatibility, Satechi equips the EX1 and EX3 with a flexible dual-connectivity system. Users can choose to use a USB-C dongle for the lowest latency or connect via Bluetooth for optimal compactness. Both keyboard models fully support popular operating systems such as macOS and Windows, allowing for smooth switching between different devices.

New aluminum mouse: An economical and durable solution.

Accompanying the new keyboard line is an aluminum mouse at a relatively accessible price. Similar to the EX keyboard series, this mouse is also designed for users who prioritize compactness and high portability. With its reasonable price, it is considered a strong competitor in the mid-range office accessories segment.

Vision for sustainable accessories at CES 2026

Satechi's focus on modular battery replacement demonstrates a strategic move in minimizing electronic waste. In a context where consumers are increasingly concerned about sustainability, Satechi's solution not only offers long-term usability but also contributes to environmental protection by extending product lifespans.
