Anker Nano 70W GaN Charger

The Anker B121A is a 70W GaN charger with three USB-C ports, designed for users who need fast charging for laptops, tablets and phones from a single compact block. It ships with a 4.9 ft USB-C to USB-C cable and is offered in a pink finish.

Compact Build and Everyday Connections

Measuring 2.09 × 1.68 × 1.24 inches, the unit is 41% smaller than a standard 70W charger and features a textured shell with a glossy finish and metal frame. ActiveShield 4.0 thermal monitoring keeps surface temperatures up to 50°F lower than safety benchmarks, while TÜV Rheinland certification backs the safety claims.

Practical Limits of the 70W Interface

Each USB-C port can deliver up to 70W at 20V and 1.8A, enough to charge a 14-inch MacBook Pro (2024) from 0 to 50% in 35 minutes. Total output is shared across the three ports, so simultaneous charging reduces the power available to each device. The charger does not support devices that require more than 70W from a single port.

Questions about this item

What USB standard do the three ports support and what is the practical power limit?

Each of the three USB-C ports can deliver up to 70W at 20V and 1.8A, so a single device can draw the full 70W while multiple devices share the total budget.

What are the exact dimensions I need to clear in a bag or outlet strip?

The charger measures 2.09 × 1.68 × 1.24 inches, making it 41% smaller than a typical 70W brick and easy to fit in tight spaces.

How do I set it up for fastest charging and what step is often missed?

Plug the included 4.9 ft USB-C to USB-C cable into any port, connect your device, and ensure the device requests 20V/1.8A — some laptops default to a lower profile unless the correct cable and port are used.
