I must add that using CA-146C, you should be aware of the said product to melt. The older CA-146C had this notorious issue with melted adapter and the new one (still bearing the same model number and what not) I am unsure if it would melt but there hasn't been any new complaints of the it melting.

I personally didn't take the risk after seeing the pictures of melted adapters (and how much they cost for just a small little thing!) so I modded the adapter myself. Details are on my own blog.

I should really post pictures of my modded CA-146C however I haven't gone around doing so.
