Is there a specific reason why you want the electrical USB port in your cup holder area vs using the 12 volt outlet in the
ashtray location? One BIG advantage is never having to worry about spilling a liquid down into an electrical outlet.
If you need additional USB connectivity (even USB-C)...you could purchase and insert one of these USB adapters...either a single or dual...and you can still be hidden from view when not needed by closing the ashtray cover...then opened when USB connectivity is needed:
