## Description

The built-in retractable USB-C cable gives you a charging connection whenever you need one, without carrying a separate cable for your phone. Pull it out, connect your device, and keep the setup neat while you’re away from an outlet.

With 10,000mAh capacity and up to 45W single-port output, this pink Anker Nano power bank is designed for portable phone charging. Its compact body and smart display make it easy to carry and check while you’re on the move.

Pass-through charging lets the power bank and a connected device charge at the same time. That’s useful when you have one place to plug in and want to replenish both before heading out.

## Quick overview

The Nano combines a built-in retractable USB-C cable with USB-C and USB-A ports, giving you three ways to connect devices. The cable pulls out for charging and retracts for storage, helping keep your bag or pocket free of a loose cord. Its 10,000mAh capacity suits portable top-ups for a smartphone during a commute, day out, or time away from a wall charger.

A smart display shows charging information at a glance, while 24/7 battery protection is designed to support safe, efficient power delivery. The maximum output is 45W from a single port. Charging speed depends on what the connected phone accepts, when using two ports, output is limited to 15W maximum per single-port use, and with three ports it is up to 7.5W per port. For the fastest available charging, connect one device at a time.

## Size & fit

Measuring 3.21 × 1.42 × 1.99 inches and weighing 8.2 oz, the power bank is made for carrying alongside everyday essentials. Its retractable cable is especially handy when you prefer an all-in-one charger over a separate battery pack and loose charging cord. The pink finish also makes it easy to distinguish from other gear in a bag.

## Everyday use

For a phone that needs a boost between home and your next stop, pull out the cable and connect directly, then use the display to check the power bank’s charging status. The 45W maximum single-port output supports fast charging with compatible devices, while pass-through charging can replenish the power bank and connected phone together when you have access to power. The power bank can also be replenished through its USB-C connection, with up to 30W input.

Customer feedback often highlights quick phone charging, the compact size, and the convenience of the retractable cable. Impressions of battery life vary, so the practical number of top-ups will depend on the phone and how it is used. This is a portable phone-charging option rather than a laptop power source, Anker recommends it for phones and quick top-ups.

## When it makes sense

It makes sense if you want a phone power bank that keeps its charging cable attached and offers multiple connection options in a compact form. Compared with a battery pack that requires you to carry a separate cable, the retractable design keeps the charging setup together, the USB-C and USB-A ports add flexibility when you need to connect another device. Choose it for everyday smartphone charging on the go, with the clearest benefit when you can use its built-in cable and charge one device at a time.
