Anker 523 Charger (Nano 3, 47W) 2-Port USB-C Charger

Two-Port USB-C Charger

The Anker 523 Charger (Nano 3, 47W) delivers dual USB-C outputs in a compact form factor. One port provides up to 27W while the other supplies 20W, allowing a phone and a tablet to charge simultaneously. Total output reaches 47W across both ports.

Single-Port High-Speed Output

When only one USB-C port is used, the charger supplies up to 45W for larger devices such as a MacBook Air. Power distribution shifts automatically between the 27W and 20W ports depending on the number of connected devices. This flexibility suits travel scenarios where only one laptop requires fast charging.

ActiveShield 2.0 Temperature Monitoring

Proprietary ActiveShield 2.0 technology monitors temperature over 3 million times per day, doubling the protection frequency of the previous 1.0 version. The charger measures 2.86oz and matches the footprint of a standard 20W adapter while delivering more than twice the power. Foldable prongs enhance portability without adding bulk.
