Real·Second Charging, Realme launches 320W fast charge + foldable 4-cell: fully charged 4420mAh battery in 4 minutes and 30 seconds

On August 14, Realme released the "320W super-light speed charging" technology, officially announcing that it can fully charge a 4420mAh battery in 4 minutes and 30 seconds.

Also released are the first "folding 4-cell" technology, the 320W gallium nitride charging head with the highest power density currently, an anti-reflective film that claims to reduce reflectivity by 80%, and the first solid-state button that supports sliding and pressing (Yes, it’s the one expected to be on the iPhone 16 Pro, used to simulate zoom and shutter).

The power of "320W Super Light Speed ​​Charging" is 33.3% higher than the 240W fast charging that Realme previously mass-produced, and also exceeds the 300W fast charging previously announced by Xiaomi, and this 320W is based on domestic UFCS integrated fast charging standard.

PS: The now common UFCS 2.0 (Universal Fast Charging Standard) integrated fast charging protocol is generally 44W (generally 33W online), but in fact the maximum power of UFCS 2.0 is 240W.

The core of the bottom layer is the "4-cell foldable battery" technology launched by Realme. It uses a flexible circuit board to connect four 2.9mm thick cells together. The new lamination process claims that the capacity of 4 cells is 10% higher than that of traditional designs.

In terms of safety, in addition to the already commercially available safety protections such as adapters, interfaces, battery overload protection, and battery fuse protection, Realme claims to have made innovations in chargers, charging protocols, and charging software algorithms.

In terms of physics, the "power transmission" technology launched by Realme sounds mysterious, but it is actually a high-power density magnetic coupling DCX step-down technology, which is used to isolate high-voltage electricity and batteries to prevent circuit breakdown. .

The real difficulty is miniaturizing its module. Realme claims to compress the corresponding module to 3mm thick, and at the same time, it can complete the voltage reduction from 40V to 20V with 98% power efficiency.

(In fact, the safety of battery cells is not a problem. Compared with the previous generation of 240W fast charging, it has 10C dual cells, each cell is 120W. The current 4 cells are 320W, and each cell is only "80W", so the load is low. 1/3).

The official 320W fast charging head is also very powerful. It is the 320W gallium nitride charging head with the highest power density currently.

The power density of 3.3W/cm is 41% higher than the previous generation 240W fast charging head, but the size of the charger is similar, and it also has dual C ports. In addition to SuperVOOC, it is also compatible with PD, PPS, and UFCS protocols (charging The computer is a 65W PD), which is quite environmentally friendly (perhaps for confidentiality or other reasons, the charger on site does not even have a silk screen).

The fastest test on site, 4 minutes and 05 seconds↑

"Regular score", 4 minutes and 32 seconds↑

Realme 320W fast charging charger has a maximum power of 328W (Realme YouTube promotional video data), in four field tests on August 14, it was fully charged in 4 minutes and 58 seconds, 4 minutes and 23 seconds, 4 minutes and 05 seconds, and 4 minutes and 32 seconds respectively (the starting power is 2% and 3%) , we directly take the detailed data of the most conservative results, which far exceeds all historical records.

Realme 240W mass production version, 4600mAh dual battery, charge to 17% in 60 seconds, charge to 20% in 80 seconds, fully charged in 9 and a half minutes;

Xiaomi 300W, 4100mAh battery, charge to 10% in 43 seconds , charge to 50% in 2 minutes and 13 seconds, fully charged in 5 minutes;

Realme 320W, 4420mAh four batteries, the most conservative results on site are (compared to Xiaomi 300W) 23 seconds to charge to 10%, 1 minute and 44 seconds to charge to 51% % (compared to the mass-produced version 240W) 28% in 60 seconds, 36% in 80 seconds, and fully charged in 4 minutes and 30 seconds.

No kidding, this 320W fast charger can indeed be called "second charge". Its charging speed is more like a capacitor than a battery.
