Is it safe to use an 85watt adapter from a 2006, 17" macbook pro on a late 2011 15" macbook pro?

Hi. My question is pretty much as the heading says :

Is it safe to use an 85watt adapter from a 2006, 17" macbook pro on a late 2011 15" macbook pro?

As far as I can tell from googling and searching around, it does appear that it is safe to do so.

Specifically this page

But I just wanted to double-check for confirmation that it is indeed safe to use the adapter from such an old mbook pro in a newer one.

The wattage is the same.

I wish to do so as I prefer the T-connector, and my older adapter has a much longer extension cord on it.

If not I may order another one from ebay.

Any idea how to check that an adapter from ebay is a true / legitimate / authentic apple adapter?

Thanks for your help.

MacBook Pro (15-inch Late 2011), OS X Mountain Lion (10.8)

Yes.

I recommend you buy one directly from Apple. There are many counterfeit power adapters on the market that could damage your MacBook Pro or potentially cause a fire.

Nearly all of them are, even if the seller insists it is "genuine OEM". Legitimate adapters from eBay are likely to be used, not new. There is nothing wrong with used, as long as you know what you're getting.

Identifying a counterfeit is possible only through close examination.
