Not long ago, digital blogger @digitalchat.com broke the news that a major manufacturer is trial-producing a 24V10A 240W charger. On July 14, the blogger confirmed that this major manufacturer is OPPO.

Digital Chat Station stated that for a battery designed with dual cells and three charge pumps, its theoretical peak power can reach 300W, but the current maximum power of the USB Type-C interface specification is With 240W, OPPO has suddenly brought C-port fast charging to the "ceiling" level this time. However, OPPO and vivo are different. Although the former tested 240W fast charging, the charging strategy is conservative, and the actual speed may not be as good as vivo's 200W.
According to Xiaolei’s understanding, the USB-IF Association has announced the latest fast charging standard USB PD 3.1. The new standard adds an extended power range, which can increase the power of the charger from the highest 100W of PD 3.0 to 240W. Perhaps in a few years, the new standard can also support expansion to higher power.

At present, vivo’s 200W super fast charge has been officially announced and will be mass-produced on the iQOO 10 series. It is said that it only takes 10 seconds to fully charge a set of batteries with a capacity of 4700 mAh. Minutes, smartphone fast charging will also usher in the "10-minute era."
To achieve such high-power fast charging, the heat generated during charging must be very large. The components inside the mobile phone are exposed to high temperatures for a long time. Although they will not cause direct damage, they will also accelerate aging. Considering this aspect, Xiaolei believes that OPPO’s conservative charging strategy makes sense.

The technological iteration speed of the Android camp is still too fast. The internal roll-out of into is very serious. In the past, the charging power was generally only about 20W. In just two or three years, it has reached more than 200W. Fast charging It has also changed the charging habits of many mobile phone users. Now, when you wake up and brush your teeth, your mobile phone can be fully charged. Looking back at apple , the current highest wired charging power for iPhone is less than 30W, leaving it far behind Android.
Of course, the marginal effect of fast charging on smartphones is still serious now. The power is several times higher than before, but the final charging time is only a few minutes faster. Xiaolei believes that the main reason is that the mobile phone has limited heat dissipation capacity and cannot maintain high charging for a long time. Power charging, so there will be what netizens call a "virtual standard". When manufacturers calculate internal power, they should also consider the actual charging efficiency.
