For Surface Pro 5, there is no alternate built-in charging method besides the Surface charging port.
The supported power requirement listed for Surface Pro (5th Gen) is 39W, with no fast charge, using Model 1800: 39W (15V @ 2.58A). A moderator-provided answer also states that Surface Pro 5 does not have USB charging.
If the standard Surface charger is not working, the supported troubleshooting path is:
- Check whether the LED light on the Surface Connect charger turns on.
- If the LED is off, blinking, or flashing, disconnect the charger from the Surface and wall power, wait at least 10 seconds, clean the connector with a soft dry lint-free cloth, and reconnect it.
- Flip the Surface connector 180 degrees and test again.
- Try a different wall outlet.
- If available, try another genuine Surface power supply.
If another Surface power supply works, replace the charger. If not, the Surface itself may need service.
