    I want to encrypt an ex-FAT formatted USB pen drive, so that a password is required to access it when it is inserted into a machine.

    It is vital that I'll be able to access the pen drive on both Windows and Mac operating systems.

    I have Windows 10 Home (not Pro) , so I don't have access to BitLocker.

    I don't need government-grade encryption or anything like that. I won't have highly sensitive material on the drive. It's just stuff I'd rather people don't have access to, if for example I misplace my pen drive somewhere.

    Is there a simple and free (or cheap) way to do this?

    There are some USB drives which already have a password protection program included in it.
    You may want to save your documents in google drive. You have 15 GB free storage. You can buy more storage if necessary.
    Here is a free program if interested.
    Instructional video is here.

    If you don't want to buy another stick or store your files in the cloud, rather than protecting the entire stick, you could simply right click, use 7-zip and password protect each file. You could change the names of the files so people inserting the stick would not know the actual file.

    It appears that although 7-zip doesn't work on Macs, there is software that can decompress 7Z files.

    I'd test with 1 file to see if unzipping and asking for a password works on all computers you'd use the stick on.
