Does the USB port charge your phone?
 

Mine doesn't. The service guy tells me no. To me, this is just bizarre, a USB port that doesn't charge. Does yours?

Charges my iPhone 5.

Depends on the phone.

Mine won't charge my Windows 8 Phone (HTC 8x), but charges my wife's, Android (HTC Evo) just fine.

Charges my blackberry z10 and my iPhone 5

Charges my nexus, just very slowly.

Charges Samsung Galaxy SIII fine.

Won't charge my S2 or gfs S3, might have to try again based on the above.

Not all USB ports are created equal (1.0 vs 2.0, powered vs unpowered), besides if you're in a bind the cigarette lighter works great and adapters are cheap.

Charges my iPhone4 but much slower that my wall charger.

Charges my iPhone 4S...but slowly like everyone else

The iPhone wall charger is 5W charger, so I would assume the USB doesn't have that full 5W output. Phones with bigger batteries will need a higher wattage and/or just charge slowly

What everyone else has said: charges really slow, as in just a c-hair over keeping it alive.

I assume it's only 1 amp port... it charges extremely slow for my iPhone 5. Depends on the phones, it might not charge the battery. It certainly doesn't charge my iPad Mini.

Any USB with a data connection charges at a max of .5A as per the USB standards. On a charge only plug you can get close to 1A on most phones. I bought a USB charger for my car so that I can use the GPS on the phone and still charge. Before it would act as if it was charging and then die unexpectedly.

The way Android and Apple signal charge rate is different. Android just shorts the data connection, Apple chargers send a specific voltage that tells the in-phone battery regulator what rate it can charge at. Charging an Android phone on a USB plug meant for Apple products won't hurt it, but it may limit it to .5A. Both will be limited to .5A on a computer or other connection that also has data capability (e.g., our car's plug).

Was wondering if there was a way to splice a 2.1 amp power feed into the usb port to charge while freeing up my cigarette lighter. I have a usb hub that has a power brick to make it 2.0 capable. Wonder if something like that could be used.

I bought a powergen on amazon for like 10$.. Charges fast 2amp works very good on my iPad /nexus 7/GS3/iPhone.. Its like begin plug to the wall.. The USB port on FRS don't even supply 1 amp of charging power that's why it charges slow..
