Anker Nano Power Bank (10K, 45W, Built-in Retractable USB-C Cable) — Black
The Anker Nano Power Bank solves the most common power bank annoyance — a forgotten or missing cable — by building a 27.6-inch retractable USB-C cable directly into the unit. Pull it out, lock it at one of six length positions roughly four inches apart, and charge without digging through a bag for a loose cord. The 10,000mAh battery delivers up to 45W output through either the retractable cable or a separate USB-C port, fast enough to bring an iPhone 16 Pro Max to 50% in about 30 minutes, while a physical USB-A port allows a second device to charge at the same time. A smart TFT colour display shows real-time charging information, and pass-through charging lets the power bank recharge itself while still topping up a connected device.
