In July of this year, OPPO released the 50W mini Super VOOC charger for the first time, which is called a biscuit charger because of its size. Since then, since the company has not put it on the market, the product has been elusive. OPPO has now started selling the portable 50W mini Super VOOC in China through the Hutai shopping mall (co-developed by Oppo, Realme and OnePlus).
OPPO 50W Mini Super VOOC charger adopts a crawler-style ultra-thin shape, a multi-curve design and a folding pin design for large-area applications.
The 50W super flash biscuit charger uses a new pulse pulse charging technology. The person in charge said that compared with the traditional charging method, pulse charging has a very short charging gap, which can eliminate the polarization reaction of the battery, the loss of the battery is small, and the temperature change is also small.
The 50W ultra-flash biscuit charger introduces a gallium nitride high-frequency switch, which reduces the single energy storage requirement of the transformer, thereby reducing the size of the transformer.
OPPO’s self-developed ACF (active clamp flyback) control architecture realizes zero voltage (ZVS) and zero current (ZCS) switching, and the switching loss is infinitely close to zero.
The 50W mini SuprVOOC charger is thinner than other similar models on the market, with a thickness of only 1.05 cm.
The charger supports popular fast charging protocols, such as Oppo’s own SuperVOOC, 27W PD (power supply), 50W PPS (programmable power supply), etc.
Oppo advertises that the size of this charger should be as small as a cookie. With the help of the foldable/retractable pin and its size, it can be carried in various pockets, including pockets for pants, shirts and coats.
