Of particular concern is this little piece: "Adapters that shipped with the MacBook Air (Original), MacBook Air (Late 2008), and MacBook Air (Mid 2009) are not recommended for use with MacBook Air (Late 2010) models. adaptor MacBook pro retina 15 inch 17 inch magsafe 2 85w display di Tokopedia Promo Pengguna Baru Cicilan 0 Kurir Instan. The OP was right to ask this question, and it still doesn't seem to have been addressed - nor do I know why Apple decided to switch voltages in the first place! Slightly different voltages, as other posters have mentioned, may work fine, or they may (in the case of higher voltages) overheat the system and cause damage in the long run, or who knows what else?
Voltages are much more important than wattages, as you can easily blow out a piece of hardware by using an adapter with a different voltage, but even the same wattage. This does _not_ mention using an adapter of a higher voltage. Although you should always use the proper wattage adapter for your Apple portable, *you can use an adapter of a higher wattage without issue.*" "Power adapters for Intel-based Apple portables are available in 45W, 60W, and 85W varieties.
Even then, as much as I move around, it'd be great to put one or two of the 85w adapters into service for the MBA so that I have plugs at the ready atĪny of the spots I work at in two different buildings.Īctually, the question is still not answered - and I am wondering too. I've already purchased three extra 45w adapters for my late-2010 MBA 13". If my concerns are without merit, though, I'd appreciate someone explaining why. I understand my concerns may be completely without merit-electricity and power adapters are not my areas of expertise. So, then, my specific issue here is that the decal on the outside of the 85w adapter does not show it auto-matching voltages down to 14.5v, only 18.5v and 16.5v. That is, I'm of the understanding that, in general, a 2-amp, 5-volt adapter should be fine with a device (for which the tip polarity and size match) requiring a 0.5-amp, 5 volt adapter. It has been my understanding that, in general (assuming tips match), that the use of higher current adapters with devices requiring lower current is okay, as long as the voltage matches. I understand wattage equals voltage times current. Wattage rating (85w) being higher than the Air adapter's 45w, or theĬurrent rating being higher-but, specifically, the higher The thing that bothers me (with respect to using the 85w adapter with the Air) isn't the Because most of my work is done at a few different desks, I ordered extra 85w adapters for my 17" MacBook Pro (one for the bag/travel, one for desk one, one for desk two). Here is an Apple article (HT2346) that seems to me to suggest that it's okay to use the 85w with the MBA:Īll that said, I have not used the 85w with the Air. From what I can tell, the consensus seems to be that you can safely use the 85w MacBook Pro power adapter with the MacBook Air.
