This is a brand new replacement (from Apple) 85w MagSafe 2 power adapter for MacBook Air and MacBook Pro Retina Display.
This is the most powerful adapter available and sold with the 15" MacBook.
I had this replaced as my previous charger wasn't working but I couldn't wait until I received it back so bought another one (hence this sale).
These are £65 new and I am willing to sell this at £40 delivered (more than 40% off shops price)
£35 now - no lowers offer than this
