Replacement AC adapter for Acer Chromebook R11
This 45 W charger delivers 19 V at 2.37 A through a 3.0*1.1 mm barrel connector. It accepts 100-240 V input at 50-60 Hz for worldwide use. The unit is brand new and includes a detachable power cord. Safety circuits protect against short circuit, overvoltage, overcurrent and overheating.
Who this suits and who should look elsewhere
Owners of the listed Acer Chromebook R11, Aspire A315-58, A317-33, A317-53 or Spin 1 SP114-31 models needing a direct replacement will find the correct voltage and tip size. Buyers whose laptops require a different connector diameter, a USB-C power input or a higher wattage rating cannot use this adapter.
Deciding specification: 3.0*1.1 mm barrel connector
The 3.0 mm outer and 1.1 mm inner diameter determines physical compatibility with the charging port. If the original charger uses this exact barrel size the adapter will fit; any other tip dimensions mean it will not connect.
