usb ports are useless

charging current is only the minimum USB 2.0 spec of 500mA which is ancient... c'mon, this is an omission. The new Civic has a 1.5Amp port. My Nexus 6P charged only 10% in 1 hour using the port in my car which is ridiculous. Amphere app measured about 390 mA being supplied on a consistent basis. For the record my Nexus 6P requires a full 3000 mA to charge at full speed. I understand that having 3 Amps available is an unrealistic expectation but at least provide 1.5 like the new Civic does.

I sometimes don't really understand how the engineers can be so thorough with some aspects of the car and not give a F about some other aspects that are much more visible.

Why complain?
The main focus of the USB ports are for media use, not to charge your device
Plug in a separate charger in the 12v power port like I did
my flash drives with music take up the USB ports anyway
The center console even has a hole to pass a cable through it with the lid closed.. so I would think that they did actually think about it

It`s intended to be a "media port", not a "charging port". My 2.5a charger worked like a champ in the 12v socket. Not trying to be dickish, just bringing the other side of perspective in.

I have never even used the USB port. Blue tooth for the music works great. and 12v and charger charges up way faster!

That is disappointing that a new vehicle doesn't offer a more current current (har har) built-in, but like many have said it's an easy though unfortunate and necessary fix e.g. purchasing additional peripherals for adequate charging.

I haven't had a chance to check - but does the 12V turn off with ignition? I only had my car a few days now and it's been crappy weather in NYC so I've had 0 change to play with anything in the car yet.

I had an RX-8 previously and only the front 12V accessory would turn off with ignition, the one in the center console was always hot. Annoyed the hell out of me as I can leave my car parked for up to 2 weeks at a time. Don't want something draining the battery in the background.

12v socket stays hot when ignition is off. I wish it didn't, but that's how it is.

I agree with Gerry, I would rather use the switched USB to charge my phone vs the Cig Lighter.
That being said I am also incredibly frustrated at the slow charge rate. So I will be buying the Cig adapter.
