The boss of Anker, a well-known manufacturer of mobile accessories, says charging times for top-end smartphones, including iPhones, will soon be reduced to about 20 minutes thanks to the latest-generation GaN chargers.
Most chargers today are silicon-based. Their biggest disadvantages are weight and size, which increase with power, and the relatively poor performance and heating tendencies associated with these parameters.
The much newer GaN technology uses gallium nitride transistors as a semiconductor in the manufacture of chargers. This allows you to achieve more power and efficiency with a much smaller size and weight of the power supply.
Apple recently released its first GaN PSU, the 140W PSU, which is being added to the new 16 ”MacBook Pro but also sold separately.
In the near future, the Cupertino-based company is expected to introduce more chargers using GaN technology that will be used to charge iPhones and iPads.
Charge your smartphone in 20 minutes?
Stephen Young, CEO of Anker, was interviewed by The Verge a few days ago. Among other things, he talked about the revolution in charging speed that is being achieved by the use of gallium nitride.
Anker has been manufacturing GaN chargers for several years. This year, he introduced GaN2 power supplies to the market, which charge up to 65 W, which can reduce the charging time of a smartphone to 30-40 minutes.
Next year, GaN3 chargers will go on sale, which Yang predicts will be able to charge a smartphone from 0 to 100% in just 20 minutes. Of course, everything will depend on the maximum charging power allowed by the phone manufacturer. The head of Anker notes that already some “brave manufacturers” allow charging their smartphones with a power of up to 120 watts.
Apple currently sells a 20W charger for iPhones and iPads, and its smartphones can be charged at a maximum output of 20-27W (using a more powerful power adapter of at least 30W). Charging time for iPhone 13 is approximately 1 hour. 30 minutes – 1 hour 50 minutes (depending on the model).
While the Cupertino-based company is very conservative about increasing the maximum charging power for fear of overheating the device and damage to the cell, it should be expected that in the near future this will allow faster charging of the iPhone, as it did with the MacBook Pro.
Of course, you shouldn’t expect the iPhone 14 to charge at 120W, but I don’t rule out that the maximum charging power will be increased to between 30W and 45W. Even if Apple doesn’t. By selling their charger with this capacity, users will be able to rely on third-party products.
Anker GaN chargers are now available in Europe. One of the most popular models is the 45W Anker Nano 2.
Ugreen also manufactures very high quality and inexpensive GaN chargers. Their 65W charger with four USB-C PD ports is on sale now.
