Just how far can the fast charging craze go? We have mused severally. Well, going by the events of the past month, it appears that it can go as far as you can imagine. We are right on the road to 300W fast charging on mobile devices. Yes, that. Just the other day, we needed assurances from device makers that 120W fast charging won’t fry batteries. Now we’re here.
In the space of a month, since the launch of the realme GT Neo 5 in China in last month (known globally as the realme GT3 from this month), we have gone from marvelling over 240W wired fast charging to the 260W wired fast charging that Infinix just announced yesterday. And, there’s a 300W fast charging mechanism that is still awaiting its date with destiny.
Just 9 months ago, we got to see Infinix’s 180W fast charging dubbed “Thunder Charge” which was an improvement of the 120W fast charging it had shipped with its Note 12 VIP smartphone dubbed “HyperCharge”.
Infinix is calling its latest fast charging technology “All-Round FastCharge” and it comprises a 260W wired fast charging and a 110W wireless fast charging. Yes, that’s right, 110W wireless fast charging. What won’t 2023 show us?
The 260W wired fast charging sees a phone go from 0 to 25% in just a minute and do the run to 100% in seven and a half minutes.
The 110W wireless fast charging, on the other hand, juices up a device in just 16 minutes.
“This innovative All-Round FastCharge technology can meet the different charging needs of users in all weathers and alleviate users’ charge anxiety in the era of 5G where power consumption has never been higher,” says Infinix in a statement.
“The charging architecture uses a 4-Pump Intelligent Circuit Design that intelligently identifies power requirements and allocates the number of charge pumps needed to work, and the upgraded 12C high rate 4400mAh battery with a multi-electrode lug structure, which ensures a high charging conversion efficiency of up to 98.5%, while also increasing battery durability. The battery retains more than 90% of its energy after 1,000 cycles,” the statement adds.
As was the case with the realme GT Neo 5 (and GT3), the charger that allows a phone to achieve the above-stated charging speeds makes use of gallium nitride (GaN) to allow for safer handling with the increased power output.
“The charger uses triple GaN material PFC + AHB innovative circuit architecture, which has high power density, small size, more intelligent and safe charging control, and a wider range of chargeable products. The charging cable adapts Emarker identification chip, with new interface structure design. This cable can carry a current up to 13A[5], and when combined with Infinix’s customized fast charging protocol, ensures that 260W high-power extreme fast charging is possible,” notes Infinix.
The fast wireless charging, on the other hand, is made possible by a combination of small-sensitive coils that have fewer coils than traditional designs and wider coils in the same space to reduces coil internal resistance so as to lower phone temperature rise, increase peak power charging time, and improves wireless charging efficiency and a fan at the base for silent air-cooling, which improves heat dissipation efficiency in typically high heat areas.
The “All-Round FastCharge”, according to Infinix, is compatible with various other fast charging protocols, including Power Delivery 3.0, the latest iteration of the industry standard.
It also supports reverse charging, for its wireless implementation, turning phones into portable chargers (power banks).
“In terms of safety, Infinix’s solution includes over 140+ protection mechanisms and 20+ temperature sensors, ensuring safe operation even in extreme environments,” says Infinix.
According to Infinix, the new “All-Round FastCharge” technology will be experienced by users soon in upcoming devices in its Note lineup. As we have always shared over the years, Infinix’s Note smartphone lineup is known for its high endurance rating and supporting 240W wired fast charging and 110W wireless fast charging will build on its renowned long battery life by offering the shortest possible charging times.
