Sony Computer Entertainment is voluntarily recalling 3.6 million power adapters that were shipped worldwide with its slim-version PS2.

Not all of the AC adapters in question may be defective but as we are not able to identify which are defective, we are voluntarily recalling all to make sure all customers are safe,” said Nanako Kato, a spokesperson for Sony Computer Entertainment in Tokyo.

In the U.S., Sony has received reports of 38 adapters overheating, with 19 cases of adapters melting. The company also mentioned four reports of minor property damage, two reports of minor burns and one report of a minor shock.
