Anker Prime Power Bank 27,650mAh (250W) Black The Anker Prime Power Bank 27,650mAh (250W) is a high-capacity portable charger built for laptop owners, frequent travellers, and anyone juggling a phone, tablet, and laptop away from a wall outlet. Its 27,650mAh cell delivers up to 250W across three ports using PD 3.1 technology, making it a strong match for 16-inch MacBook Pro users. This power bank suits people who need real laptop charging speed, not just a phone top-up. Technical Specifications Capacity & Power Battery capacity: 27,650mAh (99.54Wh). For instance, this typically supports around 4.5 iPhone 14 charges or 1.28 charges for a 13-inch MacBook Air (M2). Total output: 250W max combined across two USB-C ports and one USB-A port. USB-C output: Up to 140W per port (5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A, 28V/5A), with PD 3.1 support. USB-A output: Additional lower-wattage output for phones and accessories when all three ports charge together. Charging Behaviour Recharge input: Up to 170W max using both USB-C ports with a 140W charger, full recharge in about 37 minutes. However, this top speed applies mainly above 55% remaining charge to protect the battery. Single-device limit: 140W max per port, so the full 250W becomes available only when charging multiple devices at once. Air travel: The 99.54Wh capacity stays under the 100Wh threshold most airlines apply to carry-on lithium-ion batteries. Warranty: 24-month manufacturer warranty included. Physical Design Weight: 23.5 oz (approximately 666g), sized for a bag rather than a pocket. Dimensions: 6.37 x 2.24 x 1.96 in (approximately 16.2 x 5.7 x 5.0 cm). Connectivity: Bluetooth links the power bank to the Anker app for monitoring and control. Use Cases Will this charge a MacBook Pro? Yes. Each USB-C port outputs up to 140W, bringing a 16-inch MacBook Pro to 50% in around 28 minutes. Additionally, the power bank can keep charging a phone or tablet at the same time. Can it charge more than one device at once? The two USB-C ports and one USB-A port support simultaneous charging, with combined output capped at 250W. Consequently, each device receives slightly less than its maximum speed when all three ports stay active. Is it suitable for air travel? The 99.54Wh capacity falls within the common 100Wh limit most airlines set for carry-on lithium-ion batteries. However, exact rules vary by airline, so confirming with the specific carrier before a flight remains worthwhile. Internal link: Anker power banks
