Who Should Buy This#

Design & Build Quality#
At just 1.12 × 1.12 × 1.39 inches, the Nano 3 is genuinely tiny. It's smaller than most car key fobs and lighter than a pack of gum. The matte black finish resists fingerprints, and the build quality feels solid despite the compact size.
The foldable prongs are the standout design choice. They click into place when deployed and fold completely flat for transport. No more snagged cables or scratched phone screens in your bag. The single USB-C port sits on the front face with Anker's signature blue inner tab.
Key Features#
GaN Technology: Big Power, Small Package#
Gallium Nitride semiconductors run cooler and more efficiently than traditional silicon. That's how Anker fits 30W of output into something 70% smaller than their original 30W charger. The result is a charger you genuinely forget you're carrying.
PPS Fast Charging for Every Device#
The Nano 3 supports USB Power Delivery 3.0 with PPS (Programmable Power Supply). For iPhones, that means up to 27W fast charging. Samsung Galaxy devices get 25W Super Fast Charging. iPads charge at the full 30W. One charger handles everything in your tech bag.
ActiveShield 2.0 Temperature Protection#
Anker's proprietary safety system monitors the charger's temperature over 3 million times per day. That's twice the monitoring frequency of the previous generation. If temperatures spike, the charger automatically adjusts output to protect your device's battery health.
Foldable Prongs for True Portability#
The retractable prongs fold completely flush with the charger body. This isn't just convenient — it protects other items in your bag from scratches and prevents the prongs from bending during travel. Deploy them with a simple flip when you need to charge.
