I have an iPhone 6s Plus. I drive a 2011 Honda accord. The integrated USB port does not output enough to charge my phone. Any suggestions other than buying a cigarette lighter charger?

 

you won't get more output from the integrated socket. phones have become power hogs since then.

the only thing you could do to maintain connection to the integrated port (for audio) is get a cable that has signal split from power then solder that into two separate cables and two separate adapters.

when i want to add a USB charging cable without the bulk, i bury a cig adapter in the dash or center console.
