Use your old PSU
on 18 October 2013
Replaced a dead 5 year old MBPro with an Air. I have a few extra older PSUs (MagSafe ones lets call them) at my key locations and buying this converter means I can use those instead of spending over a hundred pounds replacing them with Magsafe twos. So yes you can save some money using these on working MagSafe ones.
This adapter is tiny 22.5x12.6x17.2mm but the strong magnet inside means it will stick to the cable (and laptop) reducing the chance of it dropping off and disappearing behind a cupboard. Or for that matter being swallowed by a kid or pet. The only decision is: do you buy one and hope you manage to keep it with you at all times or buy one per PSU and hope no one pinches it when away from your desk.
The tiny size for £9, the scepticism over Apple really needing the shape change for 'design' reasons has made me stick to one for now but I anticipate eventually buying more. It is actually a remarkable object from an engineering and manufacturing point of view, quality item with fine tolerances, I just get a bit annoyed about the reasons for its existence and the profit margin.
