I have a shorty iPhone cord plugged into the USB in the fairing storage mini-box.. I have a RAM mount on my bars and the cord plugs in while I'm using GPS on my phone. Issue is that while it doesn't drain much, if at all, (GPS, and Google Maps, is a battery hog) the USB barely even charges the phone much, if at all, past the % it's at when it plugs in. I do see that the phone is charging. I know the bikes electrical system has limits, but is there any way to beef the juice up at that USB?

 

Use the cigarette lighter port to charge and connect the device via Bluethooth.

 

Try a different cord. Some cords have issues with charging.

 

I've plugged in my iPhone almost completely dead, and it goes to a complete charge before pretty quick.

 

Never had an issue with charging, I'd definitely try a different cord.

 

+1 Never had a problem with mine. Agree with trying a different cord.

 

I had a similar issue in my car. The phone would not discharge, but barely charged. I just thought that was how it was. One day, my kid plugs his phone in, with his own cord, and it charged right up no problem. I went out and got a new cord and it worked perfectly.

 

Hmmm interesting. Will have to try that. The cord I'm using is a little 6" cord for iPhone forget where I got it from; Best Buy I think. I always try to get the good cords for that reason; but I didn't think of trying that. Great ideas Thanks!

 

The fairing USB port can supply 1A max current for charging, which should be plenty. Sounds like the the cord as most replies have suggested.

 

Increasingly, phones are needing 2 amps to charge, particularly when using power-hungry features like GPS.

A 1A charger on my Nexus 6 actually drains the battery because it keeps the screen on.

Ditto on the recommendation to plug your own adapter into the accessory/lighter outlet.
