The Anker 737 Power Bank with 24000mAh capacity and 140W output theoretically supports charging laptops that accommodate 140W USB-C charging. However, it is important to note that certain Dell laptops, including the Dell Precision 5570, may not charge at full speed due to Dell's proprietary charging protocols. As a result, your laptop may display messages like "slow charger" or "underpowered" even with the Anker Power Bank. Therefore, while the Power Bank is compatible, it might not deliver the full expected charging speed for your Dell Precision 5570 laptop.
