iPhone won't charge. "This accessory is not supported"

Hi everyone. My iPhone 3gs won't charge fast enough.

Every time I plug in my iphone 3gs to charge, it keeps getting the error message: "This accessory is not optimized for this iPhone". And even when it does charge, it will have that message, and it takes 30 minutes just to charge up 5% of the battery

What I have done=

-Replaced Charging port 2x with brand new parts (Mengtor & Wireless parts inc)

-Cleaned the board and all chips and possible connections with isopropyl Alcohol.

-Used many MANY different chargers (Wall, Car, Docks, Firewire, etc etc)

-Hard resets

And none of them have worked!! Any help guys?

Answer this question I have this problem too

Is this a good question?

Have you tried a new Apple sync cable? I have multiple cables that give me the same error.

The3gs is sensitive to cheap cables. I had one blow from a car charger I bought off eBay. The power management ic is prob bad. Possible to switch yourself if you feel up to the task. If not just take it to a repair shop

I have heard from several repair shops that the 3GS & first-gen iPad are extremely sensitive to 3rd party cables, so.. best bet is to get a new Apple sync cable.

@Alex Nguyen, did the new cables work?

I second Nick27's answer. Forgot about the Power Management IC...

Seems to me that car chargers are harmful to the 3GS, unless its a reputable one.
