In searching this site, the last discussion on USB charging cables was done almost five years ago. Has anything changed? Is there a way to charge my Surface Pro 4 on an airplane, in the car, using a brick charger? I would love to be able to use my SP4 when traveling, but haven't been able to locate an ability to use my external brick charger to keep the SP4 battery topped off.
Any solution to this problem would be greatly appreciated!

Hi Doss,
Most of the chargers that come with the Surface handles 100 to 240 volts and 50/60hz. Your Surface is designed to work best with the included power supply, however, if you love using your Surface on long flights and road trips, you can choose a power bank that has the same Voltage output.
Furthermore, you can check this link for more information about the Surface battery and power.
If you have any additional concerns, please let us know.
Regards.
