Microsoft Surface Pro series comes with top-notch specs and stellar build quality. The Surface devices are lighter than any other laptop with similar specs. One problem with having a powerful processor and bright 400-600 nits display in a light tablet like form-factor is that the battery size is small.
However, the good thing is that the Surface Pros can be charged via the USB-C port. As all recent iPhones, Samsungs and nearly all recent years’ Androids also support USB-C charging, one can use high-power USB-C power banks with 30-watt or higher output to charge Surface Pro 11/10/9/8/7.
To charge on-the-go, you can use a USB-C Power Delivery power bank with anywhere from 10,000 to 27,000 mAH capacity. The added convenience is that you can use the same portable charger for Surface 11 to 7 as for your phone.
A decent power bank for Surface Pro 11, 10/9/8/7 should charge it minimum once. The Surface Pro 11, 10/9/8/7 has a 46.5Wh battery, which means that a 20,000 mAH is the minimum battery capacity for any power bank to charge it fully once. As Surface Pro 11, 10/9/8/7 support 30+ watt USB-C Power Delivery, power banks with 30 watts or higher USB-C PD output will be perfect for it.
