We agree that onboard keyboard laptop generally not sophisticated as an external keyboard which mainly supposed for a desktop computer. External keyboards are more tactile than the built-in keyboard.
Since laptop or notebook has a limited number of the USB port, some people are looking to use an external keyboards without utilizing any USB port.
But, is that even possible?
You need a device called Bluetooth Adapter
To connect a wired keyboard or mouse without involving USB port means you need a Bluetooth adapter. This device would convert your wired devices into a wireless one while not occupying one of your laptop’s USB ports.
Wireless keyboards are nothing new, but transform wired keyboard to Bluetooth or WiFi connection is simply new. Now, let see the available way to connect the keyboard to without utilizing an existing USB port.
Please note that these methods require new hardware stuff that cost you more rather than straightly connect to USB port.
#1 USB to Bluetooth Convert Adapter USB2BT
Modern laptop has Bluetooth technology inside the machine. We can take advantage of a device namely USB2BT adapter. This device may look like unfinished electronic gear because it’s originally intended for the DIY project.
Your wired keyboard and mouse can be connected to USB2BT, then start transmitting command data to the laptop. Since it does not come with a built-in battery, you need external power supply such as a wall socket or USB power bank.
The USB2BT will cost you about $76 and appear like the average price of a well-quality Bluetooth keyboard. However, if you already have a better keyboard, purchasing this device may be a reasonable option.
#2 Nulaxy Wired USB Keyboard and Mouse to Bluetooth
While the USB2BT is designed for Arduino stuff, Nulaxy Bluetooth adapter is a more like a simplified version of the previous device. The Nulaxy Wired USB to Bluetooth is easy to use. Plus, it has 2 AA battery for its power.
This device provides two USB port with Bluetooth connection. Just plug in your wired keyboard and mouse, turn on the Nulaxy, and start pairing procedure with the laptop or tablet.
Unfortunately, when I found this device is already out of stock on the Amazon and pricing is unknown. Perhaps it still available on the local market.
#3 Or you can buy a Bluetooth keyboard
Apparently the best options yet. Since USB2BT and Nulaxy are cost you more and may be harder to find, you may want to consider purchasing a new external Bluetooth keyboard.
There are plenty of quality Bluetooth keyboard like Arteck which only cost around $27 and can last up to six months before it needs to be recharged. You can even get Amazon’s Choice Bluetooth keyboard for just $16.
In my opinion, buying a new Bluetooth keyboard seems to be the most reasonable option. But if you need more USB ports for your system, consider using USB hub to get extra ports for your peripherals.
