Genuine first-generation MagSafe 1 45 W adapter for pre-2012 MacBook Air systems. Available with either the original T-style (model A1244) or the revised low-profile L-style (model A1374) magnetic DC connector, it delivers the 14.5 V⎓3.1 A output Apple specifies for these ultra-thin notebooks. An LED on the connector shows amber while charging and green when the battery is full. The folding-plug “duck-head” and removable AC cord (included!) make travel and cable-management easy. We can supply this adapter in bulk—place your order and our team will fulfil it promptly.
