Questions & Answers for Apple 85W MagSafe Power Adaptor (for 15- and 17-inch MacBook Pro)

Yes, the computer knows how much power to draw, and using an 85W adapter on your 13inch MBPro will be perfectly safe.

The white box is a built in power converter so you should be fine with plugging it in as long as you have the adapter that changes plug types. You can check to see if other things are converters if it has something like Input: 100-240V~1.5A 50-60Hz. This shows that an electric current of 100-240 Volts can power the converter without problem, which Spain's electricity falls in. If you cannot find this on a product (though most electronics made in about the last 5-10 years automatically convert) or if you feel you would rather side with caution you can but a converter, but only leave it plugged it when you need the power because converters burn out quickly from overheating if you leave them plugged in too long.

The Apple power supplies are dual voltage (and dual frequency), so all you need is a European plug adaptor.

All three are different sizes, and obviously the higher the wattage, the larger the adapter. I frequently swap between all three (I own 3 laptops - 11", 13" 15"). Using a 45W on the 15" results in a slower charge, but it still charges. With the higher wattage chargers, they can be used on a lower need laptop with no issue at all. The laptop just draws what it needs.

You won't damage the computer. The only thing you'll lose is some protection for yourself in case the computer or power supply exposed a live AC current. I've used ungrounded adaptors in both Europe and Africa without problem.

Practically speaking you may want to try out different ends to see what fits best into the power adaptor you're going to use in Europe. You can actually get European-type ends for the power adaptor which are the best solution, but otherwise I fear the tiny US 2-prong part of the adaptor may not fit so nicely as the longer cord when you're plugging into a US to European adaptor.

No. Apple power supplies are rates 100VAC to 240VAC. You want to look for the proper power cord to prevent having to use a bulky plug adapter. I suggest calling Apple at the 1-800-My-Apple to order a power cord for the country you plan on using the device in. Something to consider is other countries that use 220VAC also use PAL instead of the US's NTSC.

You will not need to use a converter, your MagSafe Power Adapter that came with your laptop will automatically regulate the 230-240 volt power that is common in the UK and throughout Europe. You will however need an adapter that will allow you to plug in your US three prong grounded plug into the standard UK 2 prong outlet. Always remember to plug the Apple MagSafe Power Adapter into the UK outlet prior to connecting it to your computer. It’s just a "good practice" safe guard against any power spikes before connecting it to your computer. I have lived in Europe, the Middle East and Asia for fir the last 5 years and have never had an issue when using the standard macbook pro power cord with the appropriate plug adapter for that region.
