I bought a Magsafe 1 85W adapter from eBay (new, supposedly genuine) for and old 2008 MBP that I'm getting ready to sell. It charges the laptop fine but I noticed that the tip is hot. It hasn't even been plugged into a computer for hours. Is that normal or is it shorted internally?
Got a tip for us?

Magsafe connector hot even when not charging

Heat means bad electrical connection. Also check for the stuck/fallen pins, they are quite common.

The connector looks fine, no fallen pins or debris. I messaged the eBay seller so hopefully they will replace it. BTW I'm pretty sure it's genuine because nothing looks off and it even had protective plastic on the grounding pin, around the tip, etc.
If it came from eBay & you can't remember if it was Apple packaged and sealed then chances are it's not genuine

I think it was just a white cardboard box. Are they making fakes that good now? It looks just like an authentic Apple unit
Yep. I would source yourself something genuine & stop using the one you have asap.
And here's a good place to start for that:

If you have a really accurate scale, could you weigh both the "new" charger as well as your original and report the results?
Yeah, those fake MagSafe chargers have a tendency to heat up like crazy. They also tend to emit a ton of electrical noise when they're about to die so they'll interfere with anything else plugged into the same electrical outlet or power strip. It's genuine chargers all the way for me now.
I was using a cheap usb to lightning connector to charge my iphone via usb and 2 things happened straight away :
1.) Took forever to charge my iphone, about 6 hours to get 100%
2.) Even after disconnecting from usb, battery usage would be huge, completely discharged in about 3 hours.
I stopped using the fake and went back to the original and the phone got back to its normal state. Amazing what a cheap fake can do to an expensive gadget ! Lesson learnt ;-)
Cheers
mine gets quite warm.. 85W 'genuine' magsafe 1 psu with metal t-connector. all my other power supplies stay cold when not in use. don't forget there's a tiny computer inside the plug (google 'magesafe teardown' .. but it shouldn't get this hot :-/
i'm gonna wait and see if it blows up ! - need some excitement here.
