Our take on the Anker Ultra-Fast 70W USB C Nano Charger Block

The Anker Nano is a three-port USB-C wall charger rated at 70W per port, built around GaN so it fits in a 2.09 × 1.68 × 1.24 inch body. Anker says it is 41% smaller than a standard 70W USB-C charger and can take a 14-inch MacBook Pro from 0 to 50% in 35 minutes. ActiveShield 4.0 thermal monitoring and TÜV Rheinland certification address the heat that small high-wattage chargers are known for. It suits people who carry one brick for a laptop, phone and earbuds, though a single 70W port means a laptop slows down when other ports are in use.

Questions and answers

Can it charge a MacBook Pro?
Yes. Anker rates each USB-C port at 70W and says it takes a 14-inch MacBook Pro (2024) from 0 to 50% in 35 minutes. A 16-inch MacBook Pro wants more power, so it will charge, but slower.
Does the wattage drop when I use all three ports?
The 70W is shared across the ports, so a laptop gets less when a phone or earbuds are also plugged in. Charge the laptop alone for the fastest result.
Is it safe to leave plugged in?
It is TÜV Rheinland certified and uses ActiveShield 4.0 thermal monitoring. Anker says surface temperatures stay up to 50°F (10°C) below international safety benchmarks.
What comes in the box?
The charger, a 4.9 ft USB-C to USB-C cable and a welcome guide. You need your own cable for USB-A devices, and there is no USB-A port.
Will it fast-charge an iPhone?
Yes. It supports the USB-C iPhone 17, 16, 15, 14, 13 and 12 series, and the 70W headroom means the phone draws what it needs rather than being limited by the charger.
