Posted January 20, 2019 The big issue here is the voltage of the Surface Pro 3. It requires a 12v input, and that power bank only has 5v USB outputs. You could get a step up converter to create the 12v output, but then it would not have the amperage required to charge your device. Suffice to say no, I don't believe it's possible. ¯\_(ツ)_/¯ Desktop: Intel Core i7-11700K | Noctua NH-D15S chromax.black | ASUS ROG Strix Z590-E Gaming WiFi | 32 GB G.SKILL TridentZ 3200 MHz | ASUS TUF Gaming RTX 3080 | 1TB Samsung 980 Pro M.2 PCIe 4.0 SSD | 2TB WD Blue M.2 SATA SSD | Seasonic Focus GX-850 | Fractal Design Meshify C | Windows 10 Pro Laptop: HP Omen 15 | AMD Ryzen 7 5800H | 16 GB 3200 MHz | Nvidia RTX 3060 | 1 TB WD Black PCIe 3.0 SSD | 512 GB Micron PCIe 3.0 SSD | Windows 11 Link to comment Share on other sites More sharing options...
