The UGREEN MU102 90538 FUN+ Rechargeable Wireless Mouse is a versatile dual-mode wireless mouse designed for users who want comfortable everyday control, reliable wireless connectivity and the convenience of a rechargeable battery. With support for both 2.4GHz wireless and Bluetooth 5.0, the MU102 can connect to multiple compatible devices while keeping your workspace free from unnecessary cables.

Designed with productivity and everyday computing in mind, the UGREEN FUN+ MU102 features an adjustable optical sensor with four sensitivity levels: 1000 DPI, 1600 DPI, 2000 DPI and 4000 DPI. This allows you to choose a slower, more controlled cursor for detailed work or a faster setting for navigating large displays and multiple applications.

The mouse supports connection to up to three devices simultaneously — one through the 2.4GHz USB receiver and two through Bluetooth — with a convenient button allowing you to switch between connected devices. This makes the MU102 particularly useful for people who regularly work across a desktop PC, laptop and tablet.

Another major advantage is the built-in 500mAh rechargeable lithium-ion battery. Instead of replacing disposable AA or AAA batteries, you can recharge the mouse through its USB-C charging port. UGREEN specifies an approximately 2-hour charging time, while product documentation promotes extended usage between charges.

The MU102 also features a quiet-click design, making it suitable for offices, libraries, classrooms, bedrooms and shared workspaces where loud mouse clicks can become distracting. Its compact, modern design and comfortable surface make it suitable for long periods of browsing, office work, study and general computer use.

Whether you need a reliable wireless mouse for your Windows PC, MacBook, laptop, Chromebook or tablet, the UGREEN FUN+ MU102 90538 provides a practical combination of multi-device connectivity, adjustable DPI, silent operation and rechargeable convenience.

Dual Wireless Connectivity

The UGREEN MU102 gives you two ways to connect:

2.4GHz Wireless

Use the included USB receiver for a traditional wireless mouse experience.

Simply plug the receiver into a compatible USB port and connect the mouse.

The 2.4GHz connection is ideal for:

• Desktop PCs
• Windows laptops
• Office computers
• Gaming PCs
• Computers without Bluetooth

Bluetooth 5.0

The mouse can also connect directly through Bluetooth, eliminating the need for the USB receiver on compatible devices.

Bluetooth is particularly convenient for:

• MacBooks
• Bluetooth-enabled laptops
• Tablets
• Compatible Windows PCs
• Other supported Bluetooth devices

The MU102 can maintain connections with up to three devices: one 2.4GHz device and two Bluetooth devices.

---

Connect Up to 3 Devices

One of the standout features of the FUN+ MU102 is its multi-device functionality.

You can simultaneously connect:

Device 1: 2.4GHz USB receiver
Device 2: Bluetooth
Device 3: Bluetooth

A dedicated switching function lets you move between connected devices without repeatedly pairing or reconnecting the mouse.

This is especially useful if you work with multiple computers.

For example:

Desktop PC → 2.4GHz

Laptop → Bluetooth

Tablet → Bluetooth

This makes the MU102 an excellent choice for professionals, students and home users who regularly move between different devices.

4000 DPI Adjustable Precision

The UGREEN MU102 provides four selectable DPI levels:

• 1000 DPI
• 1600 DPI

DPI determines how far the cursor moves in response to physical mouse movement.

1000 DPI

Ideal for:

• Precise office work
• Document editing
• Basic browsing
• Detailed cursor positioning

1600 DPI

A balanced setting for:

• Everyday computing
• Office work
• Web browsing
• General productivity

2000 DPI

Suitable for:

• Larger monitors
• Faster navigation
• Multi-window workflows

4000 DPI

The highest sensitivity setting is useful when you want faster cursor movement with less physical mouse movement.

This can be particularly convenient with large or high-resolution displays.

---

Rechargeable 500mAh Battery

Forget the inconvenience of constantly replacing disposable batteries.

The MU102 contains a 500mAh / 3.7V rechargeable lithium-ion battery. Charging is handled through the built-in USB-C port.

UGREEN specifies approximately 2 hours of charging time.

This rechargeable design is useful for users who want:

Quiet Clicking

You can browse, work and navigate without the pronounced clicking sound associated with many conventional mice.

---

Useful for Multi-Computer Workstations
