Anker B121A 70W 3-Port USB-C GaN Charger Black with Cable

Compact GaN Charger for Multi-Device Users

The Anker B121A delivers up to 70 W from three USB-C ports in a GaN form factor measuring 2.09 × 1.68 × 1.24 inches. It can charge a 14-inch MacBook Pro (2024) from 0 to 50 % in 35 minutes and includes a 4.9 ft USB-C to USB-C cable. The 41 % smaller footprint suits travellers and desk-minimalists who need one brick for laptop, phone and tablet.

Check Your Devices Before Ordering

Each port tops out at 20 V and 1.8 A, so verify that your laptop, phone or tablet accepts 70 W over USB-C Power Delivery. The bundled cable is USB-C to USB-C only; devices with Lightning, Micro-USB or proprietary connectors will need a separate lead. Total output is shared across the three ports, so simultaneous charging splits the available power.

Sustained Load Behaviour

ActiveShield 4.0 thermal monitoring keeps surface temperatures up to 50 °F (10 °C) below international safety benchmarks during extended sessions. TÜV Rheinland certification confirms the design meets recognised safety standards for continuous operation. The compact GaN layout maintains stable output without throttling when all three ports are active for long periods.
