Suits owners needing a direct replacement

Buyers who need a charger that matches the original voltage, current and connector for this specific model will find it suitable. It is not for laptops that require a different output voltage or current rating. It is not for devices that use a different barrel size or a USB-C power input. It is not for users who need a higher-wattage unit for a larger workstation.

Deciding specification: 5.0 mm inner

The connector dimensions are the single detail that decides fit. If the laptop’s DC jack does not accept a 5.0 mm by 7.4 mm plug, this adapter will not connect. Verify the original charger’s tip size before ordering.
