USB cables come in normal USB plugs( into hub PC etc )
at the other end you get a mini plug
OR the latest which is micro plug
You probably have the mini plug cable whereas the Apple product
is a lightning plug and at other end a Micro socket
This is to allow Apple to meet the world wide adoption of the micro cable
as the charging medium for ALL mobile phones along with USB power source
To reduce the multiplicity of chargers shipped worldwide every day
Look on amazon for the cables and the pictures will immediately make sense
of the difference
so yes an Apple adapter and USB micro cable would give you a longer cable
All you need is a USB Extension Cable. Plug your current Lightning cable in to this and you will have a longer cable. It comes in different lengths.
Thank you for the responses. After thinking about what I really needed -- and not just what I presumed would be appropriate -- I just purchased another Apple USB-Lightning cable. I learned from you that (a) there's a difference between a USB mini and a USB micro connector and (b) that the make USB extension cables. I appreciate the education you've both supplied. Thanks.
