OPPO today unveiled 125W super-fast charging technology that can charge up to 41% in 5 minutes. The Chinese smartphone maker previously launched the VOOC, SuperVOOC, and AirVOOC fast charging technologies.
The temperature sensor used in OPPO's 125W fast charging is increased to 14, and the temperature of the phone does not exceed 40℃ during charging.
OPPO said that 125W Super Fast Charge technology can be used for mobile phones, tablets, and laptops, as long as the A specification-compliant Type-C interface is fine.
OPPO 125W Super Quick Charge supports VOOC, SuperVOOC, compatible with PPS, PD, QC protocols.
It supports a 12.5A current input with a high 98% conversion efficiency and a triple charge pump in parallel.
The OPPO 125W super-fast charger has positive and negative polarity in each layer of the cell, which doubly shortens the charge path and reduces the impedance of the cell.
This technology can charge a phone with a 4000mAh battery to 41% in 5 minutes. It takes only 20 minutes to fully charge the battery and the temperature is below 40°C when the screen is off standby charging.
The 20V*6.25A output from the adapter is stepped down by the three charge pumps and converted to 10V*12.5A into the battery.
Each charge pump only needs to convert 20V*2.1A about 42W of power, effectively avoiding the charge pump caused by high current. Overload, overheating.
In addition to the four temperature sensors of the previous fast-charging technology, the 125W Superfast Charge adds 10 temperature sensors, any temperature All abnormalities can be fed back to the phone and adapter immediately.
OPPO also announced 65W AirVOOC wireless fast charging technology, which can charge up to 25 percent in 5 minutes and 30 minutes. It can charge a phone with a 4000 mAh battery capacity.
It features a dual-coil design with an active semiconductor cooling solution that keeps the phone's temperature from exceeding 40°C while charging.
The 65W AirVOOC has an efficiency of 88% from transmitting to receiving. In addition to the dual-coil, OPPO is also simultaneously validating the 65W single-coil solution.
OPPO is not alone on this.
On Monday, another Chinese smartphone maker iQOO, a Vivo brand, unveiled its 120W ultra-fast charging technology at a tech briefing and demonstrated the charging speed on a phone.
IQOO said it will mass-produce the phone while hinting that it could be released in August.
The phone can be charged to 50% in 5 minutes and the entire battery in 15 minutes, the company said.
