A connected cable can mean several things
Seeing a cable between a keyboard and a computer can make a setup look complete. The question is what that cable is documented to do. Power, charging and input transport should not be treated as synonyms. If the reason for changing keyboards is a requirement for wired input, identify that requirement explicitly before choosing a product described as wireless. A visible port alone is not evidence that it fulfils the requirement.
Read the guide as two separate routes
Logitech's MX Keys Mini guide documents Bluetooth and Logi Bolt receiver connection methods. In a separate charging section, it describes using the USB-C cable and says typing can continue while charging. Those statements should remain separate in the shopping decision. 'Can type while charging' does not by itself establish that the charging cable carries the keystrokes. This article does not add an undocumented wired-input mode to the product.
The practical question is what happens without the wireless path
A recipient or workplace may need a particular approved input method. In that situation, compare the requirement with the model's documented connections rather than assuming that plugging in the charging cable changes its operating category. If the documentation does not answer your precise question, obtain model-specific confirmation before choosing it. This is especially important when the purchase is intended to solve an existing connection restriction rather than simply replace a worn keyboard.
Who the documented arrangement suits
Someone comfortable with a supported wireless connection and a separate charging routine can continue considering MX Keys Mini's compact format. Someone who specifically requires an evidenced wired typing path should resolve that point first or choose an option whose documentation clearly supplies it. The advantage of wireless placement and the obligation to maintain its connection are part of the same choice; neither should be hidden by a desk photograph showing a convenient cable.
Write two lines in the setup note
Record 'input connection' and 'charging arrangement' separately. For the first, note the actual supported computer and connection choice. For the second, note where the cable can reach without displacing normal work. Keep the exact model guide with the note. This gives a future user something more useful than 'it plugs in here' and makes troubleshooting begin with the right question instead of repeatedly moving a charging cable to solve a different link.
If two people share the desk, make the two-line note understandable to both. One person moving a cable for power should not accidentally be interpreted as completing the input setup. Clear labels can prevent that ordinary misunderstanding without changing any hardware.
