Anker Nano 3 30W Review: 8.4/10 - Tiny GaN charger with big power

8.4/10

Overview

The Anker Nano 3 (model A2147) is a 30W GaN USB-C charger that packs impressive power into a remarkably compact form factor. Released in September 2022, it features a foldable plug design, PowerIQ 3.0 technology for optimized device charging, and PPS support for Samsung Super Fast Charging. It is available in multiple colors and is designed alongside Anker’s bio-based USB-C cables.

Design & Build

The Nano 3 is exceptionally small, measuring barely over an inch on each side and weighing just 1.3 ounces. The foldable plug makes it even more portable and reduces the risk of damage in a bag. The glossy plastic exterior is available in several colors, and the compact size means it won’t block adjacent outlets on a power strip. Build quality is excellent for its class, with a sturdy USB-C port that can withstand repeated plugging. Anker’s ActiveShield 2.0 technology monitors temperature and adjusts output to prevent overheating.

Performance

The Nano 3 delivers up to 30W via its single USB-C port, enough to fast-charge an iPhone to 50% in about 30 minutes or fully charge an iPad Air in 1.6 hours. It can also charge a MacBook Air at full speed. PowerIQ 3.0 ensures compatible devices receive optimal charging current, and PPS support enables Samsung’s Super Fast Charging on Galaxy devices. The GaN technology keeps the charger cool even during extended use. When not in use, the charger draws negligible standby power.

Features

The Nano 3 is compatible with a wide range of USB-C devices, including iPhones, iPads, Samsung Galaxy phones, MacBook Air, and Nintendo Switch. It supports USB Power Delivery 3.0 and PPS for broad compatibility. The foldable plug and ultra-compact size make it ideal for travel. Anker’s environmental commitment includes 90% less plastic in the packaging and 30.9g less plastic in the charger compared to conventional 30W chargers.

Pros

  • Incredibly compact and portable
  • 30W PD fast charging for phones and tablets
  • Foldable plug for travel
  • PPS support for Samsung devices
  • ActiveShield 2.0 thermal protection

Cons

  • Single port limits simultaneous charging
  • Glossy finish can show scratches
  • No USB-A port for older cables
  • Not enough for full-speed laptop charging

Verdict

The Anker Nano 3 is the perfect travel companion for anyone who wants a tiny, powerful charger that can fast-charge phones, tablets, and even some laptops without taking up bag space.
