Anker Nano Charger (45W) Review: Compact GaN USB-C Fast Charger with Included Cable

As USB-C charging becomes the standard across smartphones, tablets, and lightweight laptops, compact fast chargers are increasingly important. The Anker Nano Charger (45W) is positioned as a portable GaN-based USB-C charger designed for users who want strong charging performance without carrying a bulky power adapter. With support for USB Power Delivery, PPS fast charging, and a USB-C cable included in the box, it aims to serve as a simple, everyday charging solution for both home and travel use.

Sitting alongside Anker’s Nano power bank lineup, this charger focuses purely on wall-based fast charging, prioritising size, efficiency, and ease of use.

What It Is

The Anker Nano Charger (45W) is a single-port USB-C wall charger built using Gallium Nitride technology. It delivers up to 45W of power through USB Power Delivery and supports PPS for compatible devices. Anker also includes a USB-C to USB-C cable in the box, which removes the need to purchase an additional cable for fast charging out of the box.

It is designed to work across a wide range of USB-C devices, including smartphones, tablets, and compact laptops that support charging at or below 45W.

Design & Build

The Nano Charger immediately stands out for its size. Measuring approximately 49 × 49 × 34.1 mm, it is significantly smaller than most traditional 45W chargers. The foldable plug design makes it easy to store in a bag or pocket without snagging, which is especially useful for travel.

Build quality feels solid despite the compact form. The casing has a clean, minimal finish and does not feel flimsy or hollow. For a charger that is likely to be carried around daily, the overall construction inspires confidence and matches Anker’s usual build standards.

Performance

With a maximum output of 45W via USB-C, the Nano Charger comfortably supports fast charging for most modern smartphones and tablets. It is also capable of powering lightweight laptops and ultrabooks that accept 45W USB-C charging, making it a practical single-charger solution for mixed device use.

Support for USB Power Delivery and PPS allows the charger to adjust voltage and current dynamically based on the connected device. This helps maintain efficient charging while keeping heat under control. Devices that support PPS-based fast charging can take advantage of more stable and optimised power delivery throughout the charging process.

While 45W is not intended for larger or high-performance laptops, it strikes a sensible balance for users who want one compact charger that covers phones, tablets, and lighter laptops without unnecessary bulk.

Safety & Thermal Management

Despite its small size, thermal management is handled well. The charger uses Anker’s ActiveShield 3.0 protection system, which continuously monitors temperature and power output during charging. This allows the charger to regulate performance when needed, helping prevent overheating and electrical stress on both the charger and connected devices.

Heat is noticeable when charging higher-power devices, but it remains controlled and within expected limits for a charger of this size and output class.

Practicality

In daily use, the Nano Charger proves to be highly practical. Its compact footprint and foldable plug make it ideal for commuting, office use, or travel. The inclusion of a USB-C cable adds convenience, particularly for users who want a complete charging setup without carrying extra accessories.

The main limitation is its single-port design. Charging multiple devices at the same time will require a separate charger or a multi-port alternative. That said, this design choice clearly prioritises portability and simplicity rather than versatility.

Verdict

The Anker Nano Charger (45W) with USB-C Cable is well suited for users who want a compact USB-C fast charger for everyday devices. It handles smartphones and tablets with ease and provides enough power for lightweight laptops that support 45W charging. Its GaN-based design, foldable plug, and included cable make it especially appealing for travel and daily carry.

Users who regularly need to charge multiple devices at once or rely on higher-wattage laptops may be better served by a multi-port or higher-output charger. For everyone else, especially those already using Anker USB-C accessories or Nano power banks, the Nano Charger 45W fits neatly into a streamlined and reliable charging setup.
