The type of connection plug may be easier to visually identify than the wattage, but for those who still have their chargers and need to replace them, the technical information is printed in tiny type on the side of the square white power-plug end of the cord.įor those with PC laptops, check with your manufacturer about replacement power cords and where to buy them. If you have access to another power adapter from a previous Mac notebook, keep in mind that you can use a compatible charger of a higher wattage than your MacBook, but using a charger with a lower wattage may not provide enough juice.
Apple gives its power adapters specific names, like “60W MagSafe power adapter with ‘T’ style connector” or “Apple 29W USB-C Power Adapter and USB-C Charge Cable.” You can use this name to search for a replacement unit on Apple’s online store, in its retail stores or at stores that sell Apple hardware, like Amazon or Best Buy.
