EF ECOFLOW Laptop Power Bank, 25,000mAh 170W, Dual 140W USB-C Ports

This is a good deal on a high-capacity and high-wattage power bank from a reputable brand. While the original price isn't specified, $56.99 for a 25,000mAh, 170W power bank with dual 140W USB-C ports is very competitive, especially considering its ability to charge laptops at high speeds.
