Guys, you are arguing so much, yet nobody here reported back whether you have tried a very cheap
iTALKonline Quality 3 Pin Mains UK Mains Charger for Amazon Kindle, Kindle DX, Kindle2, Kindle US, Kindle International, Kindle 3 3G. It was mentioned almost at the beginning of this topic that Kindle charger works with Sony.
£5 is a fraction of Sony charger's cost and nobody is interested? You spend so much time and energy on typing and arguing and testing...why re-invent the wheel?
