Incidentally, some MacBook owners have found that they prefer 85W MacBook Pro adapters to the standard 60W adapters included with their systems. If the MacBook Pro is sleeping or powered off, the 60W adapter will increase the available charge. In other words, while the 60W adapter will generally allow you to operate the MacBook Pro without draining the battery, it may not also increase the available the charge. However, the lower-power unit may not deliver enough power to MacBook Pros to offer simultaneous charging and operation. The 60W adapter can also be used to some extent with both the MacBook Pro and MacBook. It will provide ample power to both the MacBook Pro and MacBook, and will not damage the latter despite a higher-than-necessary wattage. The 85W adapter can be used inconsequentially with both models. So are the two adapters interchangeable? Yes, with a caveat. Both adapters use the same MagSafe connection point that will fit either model. A product specialist at Apple commented that although the packaging indicates use for the MacBook, the power supply would charge a MacBook slower and didn't recommend extended use."īy default, the MacBook Pro uses an 85W power adapter, while the MacBook uses a 60W power adapter. Their information didn't specify whether it was OK to use it or not OK to use it. I called Apple for a more definitive answer, but was unable to get one. The Apple store employee thought it was a bad idea to use the 85W with the MacBook, as the MacBook comes with a 60w adapter, even though Apple's packaging for the adapter indicated it was also for use with a MacBook. (I have a MacBook Pro and thought it would be good to have an adapter that we could both use). The packaging indicates that it is for use only with a MacBook Pro or MacBook. "I bought an extra 85W MagSafe Power adapter for my wife's MacBook. de Sequera recently inquired about the interchangability of MacBook and MacBook Pro power adapters. If you prefer to travel as light as possible, get an international adapter set, which allows you to take only the adapters you need.MacFixIt reader J.E. Note that these won’t always work for appliances that need to be grounded, which will require a more expensive grounding adapter. If you shop around, you can usually find one for less than $10 online ( this one also comes with a surge protector). If you travel a lot, invest in a universal travel adapter, which lets you slide out different plug formations so that you can use the adapter in outlets in any country.
If you’re packing lots of devices (like a camera, smartphone, and tablet), you should invest in multiple adapters so that you can charge all of your electronics at once. Most are small and lightweight, making them easy to pack. An adapter will allow you only to plug your appliance into another type of outlet.

If this is the case, you’ll only need a plug adapter (see below for more details).
If you see something like “INPUT AC 120/240 V 50-60 Hz 1300 W,” then your device is dual-voltage, and you can safely use it for voltages anywhere between 120 V and 240 V. If you want to use it elsewhere, you’ll need a converter. How do you know if your device is dual-voltage? Check the label and/or owner’s manual: If it says something similar to “INPUT AC 120 VAC 60 Hz 200 W,” then your gadget is single-voltage and can only be used on 120 V. Most smartphones, tablets, and other gadgets are dual-voltage, and if you use a converter on something that is already dual-voltage, you can damage your device. The vast majority of modern travel gadets are dual-voltage, meaning they automatically convert to run on other voltage systems. For a complete list of voltage requirements by country, visit .īefore you run out and buy a voltage converter, there’s a very important piece of information you need to know. While Japan, most of North America, and parts of South America and the Caribbean use voltage between 100 and 125, the vast majority of the world uses 220 to 240 volts. Most American-made electrical appliances work at 110 volts.
