I won’t replace it (until I get the new Retina 15″ in the next few months), and I’ll get an adapter to MagSafe 2 so that I can still use this one as a spare.Ultra-small 60W 16.5V 3.65A Laptop AC Adapter/Power Supply Charger/Power Cord for Apple A1181 A1184 A1278 A1330 MacBooke Pro 13 13.3-inch, Fits Apple MA538LL/A MA538LL/B 661-4269 661-4485 661-3957 (White) Our Price : Average Customer Review:Ī1184 / A1184 / MA538LL/A / MA538LL/B / 661-4269 / 661-4485 / 661-3957Īpple MacBook: MA254LL/A, MA255LL/A, MA472LL/A, MA699LL/A, MA700LL/A, MA701LL/A, MB061LL/B, MB062LL/B, And teeth marks from the cats chewing on the magsafe adapter.
Bare wire is visible between the cable cover and the “nipple” mounted to the power supply, and there are some cuts in the insulation on the cord between the power block and the magsafe adapter. I’m still using my original PS on my early-2008 15″ MBP.

Since they are all the same price, it makes sense, if you’re buying one, to buy a higher wattage PS in the event that you later upgrade your machine.Īs far as durability, it only takes a little bit of common sense to understand that you don’t pull the cord tight from the power block when wrapping it around the “wings.” The older 15″ and 17″ Pros all used an 85W Power Supply, and the 13″ MacBooks (White, Black and Aluminum Unibody) have all used 60W PS.Ī lesser known fact is that the higher wattage power supplies can be used on the smaller machines. MagSafe 2 85 W = MagSafe 85 W = 18.5V / MagSafe 2 60W = MagSafe 60W = MagSafe 2 45W = MagSafe 45W to current models, the MacBook Air has a 45W power supply, the 13″ MacBook Pro is a 60W, and the 15″ machines (Retina and Standard displays) use an 85W Power supply.The 60 Watt models are unchanged, so there shouldn’t be any difference in charging times between MagSafe and MagSafe 2 adapters. However, individual differences may not be as pronounced as originally estimated. UPDATE: Testing has shown that because of the lower voltages in the 45 W and 85 W MagSafe adapters, charging your MagSafe 2 machine may take a little longer when using an original MagSafe supply with adapter. How much of a difference there will be, we can’t say at the moment we’ll have more info once the adapters are available and we can test it. We don’t foresee any catastrophic problems from this, just the minor inconvenience of longer charge times when using the older adapter with the converter. So if you use that converter to hook an older MagSafe adapter to your MagSafe 2 MacBook, charging can potentially take longer, due to the lower voltage output compared to the newer adapters.
The new MagSafe 2 adapters output at 20 volts, while the original MagSafe adapters only output at ~18 volts. While the wattage for both adapters is the same 45W, the voltage is different. There’s only one small thing you’ll want to be mindful of. This isn’t something insurmountable Apple offers a $10 converter that allows you to connect a MagSafe adapter to a MagSafe 2 equipped MacBook. It’s a slight redesign on the current models, so your old spare MagSafe adapter or the ones from an Apple display won’t fit in the new ‘Books. Along with all the other bells and whistles covered last week, the new MacBook Pro with Retina display and MacBook Airs also sport MagSafe 2 power connectors.
