For the first time, Anker is using GaN-II technology for its new fast chargers. This optimizes the method introduced in 2018 of replacing silicon in the chip with gallium nitride (GaN). Since GaN heats up less and enables a higher switching frequency, the component can be significantly smaller with high efficiency. With GaN II, the operating frequency is increased again, according to Anker, “by more than 20%, which means that the Nano II generates less heat when converting AC to DC, even less than before.”
We can confirm this in the practical test: All three Nano II power supplies stayed nice and cool during the charging process, as did the connected devices. They support the fast charging technologies from Apple, Samsung, Google and Sony, among others. Which is the right companion depends on the intended use.
Three sizes to choose from
Anyone who is primarily on the move with a smartphone and tablet will use the 30W model for 35 euros happy. At only 53 grams and super-compact dimensions of 7.5 x 3 x 3.1 cm, this hardly takes up any space in your luggage and still refills your mobile devices quickly. Laptops such as the MacBook Air 2020, MacBook Pro 13 ”, Dell XPS 13 9360/9380, ThinkPad E490, HP Specter Folio, ThinkPad X390, Google Pixelbook and Microsoft Surface Book 2 can be filled with it.
If you often take your laptop with you on trips, it is worthwhile to use it medium model with 45W for 36 euros. It weighs 73 grams, measures 7.7 x 3.5 x 4 cm and gives correspondingly more gas when charging compatible notebooks.
That switches to turbo mode when it comes to laptops 65W model for 45 euros, which, with a weight of 121 grams and 8 x 3.6 x 4.1 cm, remains very handy and transportable.
