Can the Surface Book 3 be charged via a power bank?
I saw a community question asked in 2020, but not other results so far. I find it ridiculous that in 2022 am forced to use mains power for a PREMIUM "laptop" mobile device, and it cant be charged via a power bank.
Thunderbolt "security" issues were laughable, but let go. But I need to be able to charge my device whilst on the road.
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
I was able to charge my Surface Book 3 15' with a power bank of 20.000mAh with the following output specs:
USB Type-C1 65W max (5V-3.0A/9V-3.0A/12V-3.0A/15V-3.0A/20V-3.25A, USB Type-C2 18W max (5V-3A/6V-3A/9V-2A/12V-1.5A), USB-A 18W max (5V-3A/6V-3A/9V-2A/12V-1.5A)
Thank you for responding. Try using at least the same wattage on power supply that came with the device, you may refer to the table below:
| Power supply unit model | Surface model | Main charger | USB power on charger | Total wattage |
|---|---|---|---|---|
| 1932 | Surface Book 3 15" | 15 volts @ 8 amps=120 watts | 5 volts @ 1.5 amps=7.5 watts | 127 watts |
| 1798 | Surface Book 3 13.5" (with Nvidia discrete GPU) | 15 volts @ 6.33 amps=95 watts | 5 volts @ 1.5 amps=7.5 watts | 102 watts |

Hi CalClifford1,
Greetings!
Thank you for posting in Microsoft Community.
I understand that having a back up power for Surface devices are important specially for on-the-go cases.
What are the exact specifications of your Surface Book 3?
The Surface device can be charge using a USB-C charger. In this case, we recommend using a USB-C charger that provides at least the same wattage as the power supply that was included with your Surface (see Surface power supplies and charging requirements).
Please also see article For devices using USB-C.
