Where to find a power supply

If you’re interested in either purchasing an additional power supply or upgrading your power supply, see Microsoft Surface power supplies at Microsoft Store .

Surface power supplies are designed to work with Surface. We strongly recommend only using a genuine Microsoft or Microsoft-licensed power supply—one that either came with your Surface or was purchased separately—to charge the battery.

Additional Microsoft power supply info (if included)

If your Surface included a power supply or you purchased one separately, here are additional details:

  • The USB-A port available on some power supply units is only for charging other devices while your Surface is charging and can’t be used to transfer data. The wattage of the USB-A port is:

    • For power supplies of 100W or higher: 7.5W (5 volts @ 1.5 amps)

    • For all other equipped power supplies: 5W (5 volts @ 1 amp)

  • For info on how to properly care for the power cord and power supply, see Clean and care for your Surface .

  • The model number for the Surface power supply unit is in small print in one of two places—on the bottom of the unit or on the adapter itself.
