Chinese OEM OPPO recently unveiled its new 125W flash charge technology, which is capable of charging a 4,000mAh battery up to 41% in 5 minutes and 100% in 20 minutes. Now, just a few days since the announcement, OPPO’s sister company Realme has come out with its own 125W fast-charging solution called UltraDart. Realme’s new 125W UltraDart charging technology, which is most likely a rebranded version of OPPO’s tech, is capable of charging a 4,000mAh battery up to 33% in just 3 minutes and 100% in 20 minutes.
Much like OPPO’s flash charge technology, Realme UltraDart charging includes support for a variety of charging protocols, including USB-PPS at 125W, USB-PD at 65W, and QC at 36W. The technology is also backward compatible with older fast-charging solutions like OPPO’s VOOC, SuperVOOC, and SuperVOOC 2.0, Realme’s SuperDart, and OnePlus’ Warp charge.
In order to combat overheating, Realme’s UltraDart features ultra-temperature control with 14 temperature sensors and a vapor cooling system on supported devices. Along with that, Realme’s solution also makes use of a reversed battery layout, dual board-to-board connectors, and Multiple Tab Winding (MTW) battery cells to keep the temperatures low. Realme claims that its solution is designed to keep the average temperature at 40°C or less during the entire charging process and that without temperature control, it’s solution is capable of charging a 4,000mAh battery to full in approximately 13 minutes.
Along with the 125W UltraDart solution, Realme has also revealed plans to launch two SuperDart ultra-thin chargers rated at 50W and 65W. While the company hasn’t revealed any details about these upcoming chargers, the 50W SuperDart charger will, most likely, be based on OPPO’s 50W GaN mini SuperVOOC charger which was announced just a couple of days ago. The charger measures 1.05cm in thickness and it supports USB-PD at 27W and USB-PPS at 50W. While Realme’s charger may not feature the same design or dimensions, it might support the same charging standards as OPPO’s offering.
