Power bank with retractable cable
The Anker A1638 is a 10000mAh lithium-polymer power bank that integrates a USB-C retractable cable for direct charging. It delivers up to 45W maximum output through the built-in cable and USB-C port, supporting fast charging for smartphones. The unit measures 3.21 × 1.42 × 1.99 inches and weighs 231 grams. Its compact form and flight-approved rating suit travellers who want cable-free convenience.
Sustained charging behaviour
The power bank provides two-way fast charging with a 45W single-port maximum output for devices and a 30W maximum input for replenishment. Pass-through technology allows simultaneous charging of connected devices while the power bank itself recharges. A connected iPhone 16 Pro reaches 50% in 27 minutes, while the power bank fully recharges in approximately 2 hours. The smart display reports real-time status during extended sessions.
Thermals noise and power
Active Shield safety technology monitors temperature and adjusts power delivery to protect the battery during normal use. The solid-state design has no moving parts, so operation is silent. Advanced battery care circuitry manages the 10000mAh cell across charge cycles, and the retractable cable withstands over 20000 bends for long-term durability.

Questions about this item
Does the 45W output generate noticeable heat during extended charging sessions?
The power bank uses Active Shield safety technology and a smart display to monitor temperature, maintaining safe operation during 45W fast charging.
What charging brick do I need to reach the 30W maximum input speed?
A USB-C charger delivering at least 30W via USB Power Delivery is required to replenish the power bank in about 2 hours.
Can the built-in retractable cable charge an older phone that only has a USB-A port?
No, the integrated cable is USB-C only; you would need a separate USB-C to USB-A cable or adapter for legacy ports.
