The Anker Prime Power Bank (27K, 250W) is a 27,650mAh portable charger that delivers up to 250W across three ports — enough to fast charge two laptops and a phone at once.

Built on PD 3.1 technology, the two USB-C ports and one USB-A port combine for 250W of total output, taking a 16-inch MacBook Pro (M2 Pro) to 50% in about 28 minutes. When it's time to refill, dual USB-C input recharges the power bank itself in roughly 37 minutes.

Despite the soda-can size, the 27,650mAh capacity charges a 13-inch MacBook Air (M2) about 1.28 times or an iPhone 14 around 4.67 times. At 99.54Wh it stays under the TSA 100Wh limit, so it's carry-on approved. The Anker app adds find-my-device alerts, real-time stats, and smart charging.
