Sleek and light, it works with in-seat DC power ports available on many commercial airliners — both EmPower ports and 20mm ports (using the included adapter). Check with your airline regarding the availability of in-seat power ports.The magnetic DC plug ensures a tight connection and enables a clean break from the power port if there is undue tension — preventing your Mac from being pulled off your tray table if someone accidentally trips over the cord.*** Pictures are Part of the Description *** The item will be securely packaged and posted using an eBay partner courier service.
