Travel power bank for multi-device users

The Anker A1383 delivers 20000mAh capacity with a built-in USB-C cable, targeting professionals and travellers who charge phones, tablets and laptops from one unit. It supports a wide range of devices including iPhone 15 and 16 series, MacBook models, Samsung phones and Nintendo Switch. The integrated cable removes the need to carry a separate lead.

Sustained output and recharge behaviour

Total output reaches 87W distributed across three ports, with a single device able to draw up to 65W. A 14-inch MacBook Pro reaches 50 percent in under 40 minutes, while an iPhone 15 Pro hits 58 percent and a MacBook Air 52 percent in 30 minutes via the built-in cable. Recharging the bank itself takes 1.5 hours with a 65W charger or about 4.5 hours with a 30W PD charger at 25°C.

Usable capacity after conversion loss

Energy loss in cells and circuitry reduces the deliverable charge to an estimated 11000mAh to 14000mAh. Using the provided formula, a 3500mAh device receives approximately 3.8 full charges from a full bank. The integrated USB-C cable is rated for over 10000 bends for long-term durability.
