Anker’s Nano Charger disrupts portable charging with 70W power in a compact design

Anker’s new Nano Charger in Japan combines high power output with a remarkably small footprint, offering a versatile solution for charging smartphones, tablets, and laptops on the go.

According to ASCII.jp, Anker’s Nano Charger is drawing attention in Japan because it combines a claimed maximum 70W output with a very small footprint. The charger is being sold on Amazon.co.jp for ¥5,390, after a 10% discount, as of August 7. The appeal is straightforward: one charger for a phone, tablet and laptop, without the bulk that usually comes with that kind of output.

The unit provides two USB-C ports and one USB-A port, so it can power three devices at once. Anker says each USB-C port can independently deliver up to 70W, which is enough for a MacBook Air and similar ultraportable laptops. B&H Photo Video and Anker’s own product pages describe the charger as a practical all-round option for smartphones, tablets and notebooks.

Its compact size is another key selling point. Anker says the design uses multiple GaN chips, or gallium nitride chips, which help shrink the charger to about 55% of the size of a typical 67W model. The company also says the foldable plug and low weight, about 120g, make it easier to carry in a bag or use on the move.

Safety and stability are part of the pitch as well. Anker says the charger uses ActiveShield 4.0, which monitors temperature continuously, while the housing and weight distribution are designed to help keep the plug seated firmly in a wall socket. Notebookcheck reported that the model has also been positioned as a compact high-power charger for users who want fewer compromises between portability and charging speed.
