Anker Nano 45W 1-Port USB-C Charger (Smart Display, Foldable)

Anker Nano Charger (45W, Smart Display, 180° Foldable) Overview

Design and Build

Starting with the design, the Anker Nano Charger (45W, Smart Display, 180° Foldable) takes a compact approach, measuring just 34 × 35.5 × 40mm and weighing 75 grams. Its small form factor makes it easy to carry, while the dual foldable prongs can rotate to different angles, helping the charger fit into tight spaces and different outlet positions. 

The charger features a single USB-C port on the front and a built-in display on the body. The display provides real-time information such as charging power, temperature, charging status, and supported charging modes. It can also identify compatible iPhone models and show battery information, although some display features are limited to supported devices. 

It is not a touchscreen, but it adds a useful way to check charging information without relying on your phone. It also includes simple animations during charging, while the screen automatically turns off after a period of inactivity to reduce light and extend its lifespan.

For heat management, the charger uses GaN technology and Anker’s ActiveShield 5.0, which monitors temperature continuously during charging. It also includes Care Mode, designed to manage charging temperatures and help reduce battery aging.

Power Delivery and Protocols 

Moving on to the charging performance, the Anker Nano Charger supports up to 45W USB Power Delivery (PD) through its USB-C port, making it suitable for fast-charging compatible smartphones, tablets, and other USB-C devices. It supports multiple PD output profiles, including 5V/3A, 9V/3A, 15V/3A, and 20V/2.25A.

The charger also supports PPS (Programmable Power Supply) up to 3A, allowing compatible devices to adjust voltage and current dynamically for more efficient charging. However, this 3A PPS limit affects charging speeds on some Samsung Galaxy models. Devices such as the Galaxy S23+, S23 Ultra, S24+, and S24 Ultra require 5A PPS to reach their 45W Super Fast Charging 2.0 speeds, so they are limited to 27W Super Fast Charging with this charger.

While, the newer Galaxy S25 series is an exception, as these models can achieve their supported fast-charging speeds with a 3A PPS charger. For other compatible devices, the charger can deliver up to its rated 45W output, with power automatically adjusting according to the device's charging requirements.
