I noticed that the new mbp 13" charger plugged into the wall, the wall adapter gets very hot.
is that suppose to happen?
 
A few people have had 'asploding ones. Maybe you should bring in your notebook and charger and Apple will give you a new one. After spending a week on this forum it seems as if 75% of the people here would do that.
 
Wfm

Not here - my power adapter is nice and cool. Plugged into the wall with the three prong adapter and all.

I'd be concerned if yours is unusually hot. I've read here of a number of people having problems with them.

For what it's worth, I'm in the US using 110v. I'm curious if people using 220v are having different experiences.

Ok I was using the 2 prong adapter
I will try the 3
 
it is normal for them to be hot. What I have observed however is that if you have add that extension cable then it really gets hot.

To the contrary, I noticed that when I use the extension to the 3 prong wall connector that it becomes less hot, but still warm. Jut my personal experience.

im just worried about the magsafe adapter to the macbook and pray it doesnt burn or something.
 
Everything's relative I suppose. I haven't used a Mac laptop before I got this MBP 17" last week, and I gotta say this 85W adapter is lukewarm at most. Every adapter for every Dell laptop I've owned previously would get twice as hot as this one (despite being larger), to the point where you can't hold it in your hand for more than a couple of seconds without getting a lasting burn. I was always careful to keep them away from carpets and other textiles, I don't think that's gonna be a problem here.
 
mine started getting hot...then it burst into flames and burned my desk , firewire 800 cable...

return that adapter.

ok my adapter is very hot plugged with the 3 pong into the outlet where you can hold it only for 6-7 secs.
my laptop temperature using istatspro is at 55'c.

very strange.

Is there supposed to be a correlation between laptop temp and charger temp? The only part of your computer that should get hot when charging is the battery/compartment, no?
 
come to think of it, mine was really too hot when I unplugged it from the 3 prong adapter on friday. so much that I waited for it to cool down before placing it in my bag.

it's fully charged already so wonder if the 'charging' state has anything to do with it - runs less hot when already charged...?

we'll see how it goes today.
 
Side question: how long is the total power cord? (from wall to laptop)

Probably close to 3.5, 4 meters (≈10-12 ft) total with the power brick at the middle. You can remove one of the cords and replace it with a small plug that snaps onto the power brick.

Have you also noticed that they charge faster compared to the old UMBs? Maybe you should also take that into consideration.

I did speak to apple specialist over the phone who asked me some questions fire hazard related lol.
I said its just piping hot buddy.
he said it was fine and should not worry etc etc.
according to him, as long as there is no sparks or fire or any DAMAGE yet, im fine ;)

and then when and if it does catch fire they ask your more questions then a doctor who thinks you have colon cancer....


its ridiculous.
 
Just make sure you have it in your life insurance policy to whoever inherits your computer that Apple replaces the computer/adapter after you die in the housefire.
 
The MagSafe Power Adapter came with the new 13" uMBP is definitely hotter than my previous gen MBP (85W MagSafe). It didn't matter if the uMBP was fully charged or not, when it's plugged in for awhile, there is a burning sensation to the touch. When it's removed from extension or wall plug and replug back, it showed some sparks!!!

Here is the Model No came with unit:
60W MagSafe Power Adapter Model No: A1330

For those who went to exchange another MagSafe Power Adapter from Apple Store, what Model No do you get?
 
cant believe this thread got this long. Chargers get warm, end of story, when the batt. is drained, or you use a monitor with it, it gets warm/hot. Whats there to discuss
 
To the electricians: do you NEED to use the 3 prong cord? I was under the impression that it was safer because it is grounded. Is this true?

Is it okay to use JUST the 2 prong block charger?
