magsafe 85 watt after market compatible with 13"?

[pcpete]

We are setting up our system for reordering power supplies for computers. I was at the point of mac power supplies. Often we will just carry 90 watt for certain types of windows laptop adapters since they can be used in both 90 and 70 watt. I am not so sure I can do that with with these mac adapters

I was reading on the wiki that each pin puts our different voltages for different models. Does that seem correct? I usually use after market chargers to keep the price reasonable to the end user. I was looking at these

or
http://www.amazon.com/MacBook-Repla...F8&qid=1438632950&sr=8-14&keywords=magsafe+85

They only mention 18.5 volts, but I am assuming if the are used for a 13" mac they must also output other voltage via another of the pins. Does that seem correct?

Your customers may be different than mine, but mine prefer real Apple adapters. With the crap that comes out of China for third party adapters, It's not worth it to sell someone a knock off, only to have something go wrong with their $1200 laptop and have them blame it on the cheap adapter I sold them. I mark it up for the convenience of me having it when they need it.

Doesn't answer your question, I know.

I agree with @altrenda. Not worth the risk using no-QA'd 3rd party stuff.

We recently started using pwr+ brand for all of our windows computers. I think they are better than genuine.

I agree, we may start using genuine for apple.

 

[pcpete]

what are you guys paying for genuine? where are you buying them? What about the genuine ones listed on amazon?

No shop or store front so I'm not reselling. AC adapters are pretty simple so I let them order on their own. If they ask about the cheap stuff on eBay I tell them they are on their own. I've had mixed results with AC adapters from eBay.

I'll throw in my agreement : all third party adapters i've used are CRAP.

They're poorly made, throw noise into any computer that's used for Audio production, and usually fail after 6 months or so.
