Wall charger not charging iPhone

mine die after 1 moth of infrequent use. I went to an Apple store, was told that had to wait an hour or make a appointment to swap the AC adapter. it is kind of ridiculous that an appoint is needed for swapping an AC adapter. The GENIUS explained to me that he needs to do paper work and he had to help others that were waiting in line. The time he took to explain that to me could have completed the swap already. I was kind of upset cause I couldn't wait, and had to make another drive to the Apple store again another day. As I walked out of the store, I notice there are 10+ sales person wondering in the store, and only 2 GENIUS helping out people with problem.

I'm really glad I found this thread. I was beginning to wonder if I was crazy. I've been having the exact same symptoms as what is being described here.

I have two iPhone charging kits (I frequently commute between cities), and about two weeks ago, one of them simply stopped charging the iPhone--I had to plug the USB cable into my PowerBook and charge it that way. Yes, I tried every outlet, and yes, I was sure that the outlet had power. Since i bought it from the Apple Store, I was going to return the AC brick and swap it, but I saw that Apple charges a restocking fee if it's not defective, so on the last day of my 14 day return period, I tried it and it worked... now it seems ok. But then this week, my second AC brick stopped working, and it is still dead. I have to charge off my computer.

Going to take it to the Apple Store and see if they'll swap, but I'm not sure it will help if they are all defective. Apple: Please, PLEASE recall these things and fix them! I don't trust the iPhone charger enough to travel with it. If I don't take my PowerBook, and the AC brick fails on a trip, I'm going to be SOL.

This has to be a result of firmware 1.01. Mine was working fine, I took out the USB cable to update the firmware, and now the power brick won't be recognized. Also, I lost my sounds (keyboard clicks, etc.) and music won't play through my speakers. Highly annoying!

Mine stopped working after 4 weeks of daily use. Called apple and they sent me a new one 2 days later. The new AC adapter didn't work either! Tried hard reset, restore, switching prongs, switching outlets, etc. Is it a phone issue? They are sending me a temp phone while I send mine in for them to look at. I gotta say though, I love Apple customer support. they rock.

I've had an interesting ecperience with the iPhone charger I would like to relate. It may contain a clue to the problem for the techs. My included USB charger works perfectly at HOME. In the past 3 weeks, I've stayed in 2 hotels. One in Florida and one in California. The AC charger would not work. My car charger (Griffin) worked fine. It also charged fine from a laptop using USB. This has been a real mystery to me. Any ideas folks?

My iPhone charges normally with the larger brick that came with one of my iPods however, it doesn't charge with the small one that came with the phone. The same thing happens when I try to charge my iPod.

I decided to measure the output of the larger iPod brick vs the smaller iPhone brick.

While the larger brick had a steady output at 5.2V, the smaller brick fluctuated rapidly between 4.3V and 4.8V.

As far as I know, USB specs require an output between 4.75V and 5.25V therefore I think that the output of the small iPhone brick is too low for both the iPod and iPhone to recognize it properly. I'll go back to the Apple Store tomorrow...

Any thoughts?

UPDATE

I went to the Apple Store and, after an appointment at the Genius Bar, they replaced the non-working charger.

To make sure, I measured the output of the charger both at the store and at home and it showed a steady 5.1V, therefore my phone recognizes it properly and charges normally...

Well, this is weird how different Apple store handle things differently. I went to the Apple store at Pasadena, CA to swap a dead charger, I was told I had to wait inline to do paper works.. etc, and the line was long. So, I left to come back another day. Then, I was in Glendale Galleria, and I stop by the Apple store then to see if the line was long. They just gave me one on the spot, no question, no forms..
NOTHING.

Ditto on all counts. Mine worked fine for a month. Last night it was plugged in at my boyfriends house and charge beautifully. Came home, plugged it in and now it won't work. Still charges fine from the laptop. Swapped out the prongs with the set from my macbook. No dice. On my way to the apple store, 10 bucks says they get it to work no problem.

Add two of ours to the list. Both our charges stopped working on a vacation this weekend. Both at the same time.... luckily USB ports exist all over and I was able to charge our phones..

off to apple store to get them swapped out

I had the same issue, narrowed it down to the wall charger, and then brought it into the Apple Store. When they tried it, it of course worked. The problem was that they would not replace it. The 'genius' said to reset the phone and try it again later. Now the phone is in Arizona, and there is no Apple Store anywhere near here. This blows.

Add me to the list. I swapped the plug with a friend and the craddle worked fine. Also swapped his plug with mine on the brick and it did not work so it looks like it is the brick. I'll try plugging and unplugging the USB wire to see if that helps as someone suggested. Otherwise it is back to the Apple Store.

i had the same issue... but it worked in iowa, went to wisconsin to visit my sister and the charger did not work. now, probably just a coincidence, it just stopped working in iowa after the 1.0.2 update.

I had this issue happen last month with my iPhone charger and then just yesterday with my wife's. In both instances, they were replaced on the spot, without me having to wait for a Genius to tell me it's not working. I appreciated the quick turn-around. They must be aware that that there's a few bushels of bad apples here.

I had the same problem 3 x. I checked the usb wall charger for voltage, nothing, changed cable, nothing. cable assemblies are good. Was told I could call or take back to apple. Well, I tried testing them again so I wouldn't look like an idiot, Both of the USB wall adapters I thought were bad now worked. Still working. I suspect something internal. Can't fix what's not broke!
