Question about USB-rechargeable trackpads

[GanChan]

I need a rechargeable trackpad for my Mac Mini setup, and I'm considering something like the Logitech Trackpad. I've found some refurbished/used options in addition to buying new, and I was just wondering:

-Will a used trackpad have a shorter charge life than a new one?
-If the unit loses its ability to hold a charge, can I still keep it powered merely by leaving it plugged into the USB connection?

I have no general issues with buying pre-owned stuff, but it never hurts to know these things in advance....

Thanks!

Dunno, but it looks like the battery isn't that hard to replace when the time comes. <https://www.ifixit.com/Teardown/Magic+Trackpad+2+Teardown/51032>

All lithium batteries will slowly hold less charge as time goes on, even if you don't use it. So an older model might need to be charged every 2-3 weeks vs every 4 weeks, for example. A refurbished model should have a new battery (the Apple ones all do).

My Logitech MX Master mouse is rechargeable, but it still works when charging so I imagine any rechargeable device can be both charged and used (except the Magic Mouse 2 because the charging port is in a strange location). It looks odd when the mouse is plugged into a random charger and yet it still works to move the cursor.
