Some people buy a Bluetooth mouse because they think they can get rid of the tangled cable and save more USB ports. But, some products are shipped with a USB dongle, which means the port needs to be sacrificed.
But is a USB dongle really necessary? There is no free USB port left in my device, how can I deal with this issue? Can I use my Bluetooth mouse without connecting its USB dongle?
Yes, you can use a Bluetooth mouse without its USB dongle

Some Bluetooth mice are tied to a USB dongle, but it works fine without it. If your notebook, laptop, or desktop PC already has a Bluetooth connection, you don’t need to plug in a USB dongle.
Only install dongles when your device does not have Bluetooth. Manufacturers usually provide additional dongles only if their customers do not have a Bluetooth connection on their devices.
On the other hand, if the mouse does not include a dongle in the product packaging, this means that the device can work with the built-in Bluetooth – no additional dongle is required.
If you are considering using Bluetooth on board, it may require manual installation by adding a new device. Please refer to the manual for a step-by-step process of pairing. Meanwhile, the USB Bluetooth dongle is designed to instantly connect to the mouse without interference.
Can I connect multiple devices with Bluetooth?
Yes you can For example, I have built-in Bluetooth in my laptop and I often have a mouse, earphones and printer connected without interference. I can even lock the device via Bluetooth using my smartphone.
Unlike Bluetooth, a Wi-Fi-based mouse still needs a special connection to its Wi-Fi dongle. It will not work on board due to different frequencies. In other words, a USB port is required to connect the dongle.
This is the downside of a Wi-Fi mouse. Needless to say, if your device does not have a regular USB port, you will need an additional USB converter. However, it is known for being more reliable, higher response time, and longer battery life.

My favorite Bluetooth mouse that can run without a dongle
I have a Logitech M557 Bluetooth mouse that can be used for up to 12 months. It does not come with a USB dongle as it is designed for users who already have Bluetooth connectivity in their device. I also have the Logitech M331, a Wi-Fi mouse that requires a Wi-Fi receiver (dongle) from my computer.
Of course, there are many wireless mouse products out there. You don’t have to stick to those options – they’re just an example. If you plan to purchase a wireless mouse, please make sure it is a Bluetooth mouse or Wi-Fi mouse.
