Asked my mom to get me the Apple 60W MagSafe 2 Power Adapter from iStudio in Changi Airport because she is travelling to Hong Kong with my dad. The retail price is S$108 but if you get it from the Airport, you don’t have to pay tax for it. So it is cheaper by about 7%, so it cost about S$100.93.
The Apple 60W MagSafe 2 Power Adapter is meant for MacBook Pro Retina 13″. As long as your MacBook uses 60W or less, you can use this particular adapter. Case in point, you can use this power adapter with MacBook Air 11″ or MacBook Air 13″.
The Apple 85W MagSafe Power Adapter is for 15″ and 17″ MacBook Pro. Got it in Hong Kong for only HK$588 (~S$93). It is selling for S$128 in Singapore!
I am also using a 15″ MacBook Pro for work and I have a power adapter at work, it has been wired so nicely that it makes removing it very difficult and hence I decided to get a spare power adapter that allows me to bring it along when I am on call.
