Full Speed. Cable Ready
The Anker Power Bank (20K, 87W, Built-In USB-C Cable) (model A1383 or similar variants like A1383H11) is a versatile, high-performance portable charger designed for travelers, professionals, and everyday users who want convenience without extra cables. With a substantial 20,000mAh capacity (approximately 72Wh, airline-friendly under 100Wh), it delivers up to 87W total output across three ports: a built-in retractable USB-C cable (durable for over 10,000 bends and tested for strong pull force), one additional USB-C port, and one USB-A port.
This allows simultaneous fast charging of multiple devices, with a single port reaching up to 65W via PD (Power Delivery) for laptops like MacBook Air/Pro (e.g., charging a 14-inch MacBook Pro to 50% in about 40 minutes or an iPhone 15/16 series rapidly), while the USB-A supports up to 22.5W for phones or accessories. The built-in cable eliminates the hassle of carrying separate ones—simply extend it to charge directly—and the power bank recharges quickly at up to 65W input (full recharge in around 90 minutes via the USB-C port or built-in cable). Compact and lightweight at roughly 6.2 × 2.9 × 1.0 inches (157 × 74 × 25 mm) and 15.5 oz (about 440g), it includes a clear digital display for real-time battery status, compatibility with a wide range of devices (iPhone, Samsung Galaxy, MacBooks, Nintendo Switch, and more), and Anker’s reliable safety features like temperature control and overcharge protection. Perfect for on-the-go use in Nairobi or international travel, it’s a reliable all-in-one solution that combines power, speed, and cable-free convenience.

FAQs
Is the built-in USB-C cable capable of delivering the full 65W charging speed?
Yes, the retractable built-in USB-C cable supports up to 65W PD output, just like the dedicated USB-C port. It can fast-charge laptops (e.g., MacBook Air to significant levels quickly) or phones efficiently. Users confirm it performs at full speed when used alone, though multi-device use shares the 87W total output.
Why does the power bank provide fewer full charges than the 20,000mAh rating suggests (e.g., not 4-5 full iPhone charges)?
This is normal due to energy conversion losses (efficiency around 70-85%), voltage differences, heat, and cable/device factors. The actual usable capacity is about 11,000-14,000mAh equivalent for devices, so it typically delivers 3-4 iPhone charges or 1+ laptop top-ups—common across all power banks, as noted in Anker’s explanations.
