Anker Power Bank (20K, 87W, Built-in USB-C Cable) Black The Anker Power Bank (20K, 87W, Built-in USB-C Cable) is a high-output portable charger built for travellers, remote workers, and anyone charging phones, tablets, and laptops away from a wall outlet. Its 20,000mAh cell pairs with an integrated USB-C cable, so there’s no separate cord to pack for daily charging. This power bank suits people who need laptop-level output in addition to standard phone charging. Technical Specifications Capacity & Power Battery capacity: 20,000mAh. For instance, this typically supports 3 to 4 smartphone charges depending on device battery size. Total output: 87W combined. Specifically, this splits into 65W max through the built-in USB-C cable or USB-C port, and 22W max through the USB-A port. Single-device maximum: 65W, available through either the built-in cable or the separate USB-C port. USB-A output: Up to 12V/1.5A. Additionally, this port suits accessories and older devices without USB-C. Physical Design Weight: 430.91g (approximately 15.5 oz). Consequently, this size suits a bag rather than a pocket. Dimensions: 15.75 x 7.35 x 2.6 cm. Cable: Built-in USB-C cable, rated to withstand over 10,000 bend cycles for daily use. Charging Behaviour Recharge time: Approximately 1.5 hours using a 65W charger; slower chargers extend this, with a 30W charger taking around 4.5 hours. Device compatibility: Works with USB-C laptops, phones, and tablets, plus USB-A accessories through the third port. Warranty: 18-month manufacturer warranty included. Travel note: The 20,000mAh capacity stays within common airline carry-on limits for lithium-ion power banks. Use Cases Will this charge a laptop? Yes. The 65W single-device output charges many USB-C laptops, including a 14-inch MacBook Pro to 50% in under 40 minutes. However, laptops with higher power requirements may charge more slowly. Can it charge three devices at the same time? The built-in USB-C cable, a separate USB-C port, and a USB-A port allow simultaneous charging. Additionally, total output stays capped at 87W combined, so each device charges a bit slower when all three are active. How long does a full charge last? A 20,000mAh capacity typically covers several phone charges or one to two laptop top-ups before needing a recharge. Consequently, this power bank suits multi-day trips without regular access to an outlet. Internal link: Anker power banks
