MagSafe overheating

Question

Hello, My MagSafe charger has given out (like many if we believe this: http://www.apple.com/fr-business/shop/reviews/MA538F/B/apple-magsafe-60w-power-adapter-for-macbook), so I bought a "fake," meaning a no-name one a few months ago.  I know: it's bad!  Well, everything was fine until these last few days, when I noticed that the connector (I don’t really know what it’s called, the thing that makes contact with my Mac) is overheating, especially if it's plugged in while I'm using the computer (it’s less of an issue if I charge with the computer not in use/closed). It freaks me out; I'm afraid I'm going to fry my Mac.  Would you recommend I go buy a genuine MagSafe with the apple logo on it? (ugh, €89 still!)  Thanks for your advice.    Configuration: Mac OS X Snow Leopard (10.6.8) / Chrome 49.0.2623.112

Hello,  If the charger overheats... it can be unhealthy and damage the connectors, yes.  "Pirate" chargers always carry this risk: you pay less, but you don't know what you'll get... sometimes with chargers that explode.  -- ~ To know how to listen is to possess, beyond one's own, the minds of others... said Leonardo da Vinci.

Hello, I decided to buy an Apple brand charger after asking the store to take a look, and they tested it with a charger at customer service. Since it was working, I went to buy one. But I couldn't remember if I needed a 45W, 60W, or 85W. The customer service told me they charged it with an 85W, so I should get that. But the notice on my Mac indicates 60W. I called customer service again, and they said that since it had worked with their 85W, it was fine and that "if it can do more, it can do less."  Is that really the case? I haven't unpacked it yet; should I go change it for a 60W?  Thank you for your advice.

Hello,  Indeed, an 85 W charger can perfectly replace a 60 W one. It's the other way around that would pose a problem. What is important to respect is the voltage delivered. It is the same for the different chargers. 85 W simply means that this charger has a greater capacity than the 60 W one to provide the requested current. One could even imagine that Apple only manufactures 85 W or even 100 W chargers to cover its entire range, but if Apple continues to provide 85 W, 60 W, 45 W... it’s for cost reasons. A small MacBook Air 11" does not need as much current as a MacBook Pro 17"... but the charger of a "big" MacBook will be able to provide the current required by a "tiny MacBook"... who can do more can do less... indeed.
