Magnetic accessories have become increasingly popular in the tech world, but they've primarily been limited to phone chargers and holders. Now, peripheral maker ESR is bringing magnetic technology to computer mice with its innovative MagMouse, which has just launched on Kickstarter. This unique wireless mouse is designed to magnetically attach to laptops for easy portability, addressing the needs of on-the-go professionals and students.
A Magnetic Solution for Mobile Users
The ESR MagMouse represents a novel approach to mouse portability. Weighing just 75 grams (2.65 oz), this lightweight travel mouse features embedded magnets that allow it to attach securely to laptops and tablets. The magnetic connection works through a detachable base that attaches to your device using reusable 3M adhesive. According to ESR, the magnetic base offers a strong 600-gram holding force, enhanced by retractable magnetic pins that align and lock precisely with the mouse. This double-locking design aims to prevent accidental detachment while moving between workspaces with your laptop in hand.
Built-in USB-C Cable and Versatile Connectivity
Perhaps the most innovative feature of the MagMouse is its built-in USB-C charging cable that folds neatly into the mouse's body when not in use. This thoughtful design element eliminates the need to carry a separate charging cable, making it truly portable. The mouse supports both Bluetooth 5.0 and 2.4GHz wireless connectivity, with the 2.4GHz USB-A dongle storing conveniently in a slot beneath the mouse. This dual connectivity ensures compatibility across Windows, macOS, iOS, iPadOS, Android, and Linux devices.
Performance and Battery Life
The MagMouse offers adjustable DPI settings ranging from 800 to 4800 across six levels, providing flexibility for different usage scenarios from photo editing to casual browsing. It features seven buttons and a four-way scroll wheel, making navigation through documents and spreadsheets more efficient. ESR has also implemented silent switches that reportedly reduce noise by about 90% compared to conventional mice, making it suitable for quiet environments like libraries or shared workspaces.
Battery life is another strong point, with ESR claiming up to 160 hours of use on a full charge. The charging process is quick, taking approximately 45 minutes for a complete charge, with a one-minute quick charge providing about four hours of runtime—a potentially valuable feature for users caught in low-battery situations during meetings or presentations.

Limitations and Compatibility Considerations
Despite its magnetic design, it's worth noting that the MagMouse isn't MagSafe compatible and won't stick to iPhones, Samsung Galaxy phones, or other devices with MagSafe/Qi2 technology. The mouse is specifically designed to work with ESR's own magnetic laptop docking pad, which is somewhat bulky due to the pins that help secure the mouse. While the mouse can lightly stick to fridges and metal rings designed for third-party magnetic accessories, ESR doesn't recommend these alternative attachment methods.
The docking pad's sticky gel surface, while reusable and washable, may make it challenging to slide laptops into tight sleeves or cases. Additionally, the magnetic connection, while secure for carrying, isn't strong enough to use the mouse as a handle for the laptop or to open stiff laptop lids.
Pricing and Availability
The ESR MagMouse is currently available on Kickstarter with early bird pricing starting at USD $24, representing a 32% discount from its planned retail price of USD $36. It comes in three color options: black, white, and gray, each bundled with a color-matched magnetic base. According to ESR, shipping to Kickstarter backers should begin on June 6th, though potential buyers should consider the usual caveats associated with crowdfunding campaigns, especially given the uncertain import situation related to recent tariff changes.
A Promising Concept with Room for Improvement
While the MagMouse represents an interesting innovation in the peripheral space, some may question why ESR didn't fully integrate its magnetic expertise by incorporating wireless charging or better compatibility with the broader magnetic accessory ecosystem. For frequent travelers, the value proposition is clear—a lightweight mouse that attaches securely to your laptop could eliminate fumbling through bags for peripherals. However, the requirement of ESR's specific magnetic pad rather than compatibility with existing magnetic solutions might limit its appeal for some users already invested in magnetic accessories.
