The Anker Prime Power Bank (26K, 300W) is a high-capacity USB-C battery pack built for laptops and travel. It pushes 300W total across two USB-C ports and one USB-A port, with up to 140W on a single port, enough to run two MacBook Pros at full speed. Its standout is recharge speed: 250W dual-port input refills it to 50% in about 13 minutes. The 26,250mAh (99.75Wh) cell sits just under the TSA carry-on limit, so it flies legally. It suits frequent travelers and laptop-heavy users who want desktop-class charging in a bag; rivals in this class usually top out near 140W output and recharge far slower.
