At present, The world’s fastest charger owned by Oppo, that is Oppo SuperVOOC, The 2nd number is Huawei with Huawei Quick Charger while Samsung is an innovator in Mobile phones but they don’t focus on their charging speed they only give 15W charger in the box (But Apple don’t), But with Samsung Galaxy S10 & S10 Plus, Samsung May change this method.
Reports say that Samsung may their Typical Adaptive fast Charging and they give us Approx 40W in the box with Samsung S10. They may be called it Samsung Super Fast Charging. But I just think, If Samsung Focus on their Battery Charging Speed. Oppo should upgrade their Charging speed to maintain Worl’s Fastest Charger Title.
