OPPO 50W mini SuperVOOC charger
Apart from World leading 65W AirVOOC wireless charging and 125W wireless charging Oppo also introduced OPPO 50W mini SuperVOOC charger and 110W Mini Flash Charger.
The OPPO 50W mini SuperVOOC charger pioneered the ultra-thin runway shape. The large-area application of a multi-radian curve design is round and delicate like a pebble. The thickness is only 10.5mm. With the design of the folding pin, it is easy to adapt to daily storage and carrying. The jeans pocket is super small and has no burden.
In terms of specifications, the 50W super flash biscuit charger is compatible with SuperVOOC and VOOC flash charging. It supports 27W PD, 18W QC, and 50W PPS and another industry general fast charging protocols, and can be used for fast charging for mobile phones, tablet computers, and other devices.
How small is the OPPO 50W mini SuperVOOC charger?
8.22×3.9×1.05cm, or 33.66cm³, which is about the size of a biscuit, I think. exactly where its product naming comes from. For comparison, OPPO’s previous 50W SuperVOOC charger was 5.19 x 5.19 x 3cm and 80.8cm³, more than twice the size.
To adapt to high power, its miniaturization must break through traditional solutions. Traditional chargers need to rely on built-in electrolytic capacitors to achieve stable power output. However, with the increase of power, the volume of electrolytic capacitors needs to be increased accordingly. The traditional transformer causes a high-power charger under the traditional scheme to remain high.
In response to the volume problem of electrolytic capacitors, the OPPO flash charging team designed a new generation of revolutionary technical architecture: no electrolytic capacitor design, and the industry’s first introduction of a smaller aviation-grade device-a clamping diode, to absorb surge surges up to 250KW, allowing the charger safely supports the full grid voltage.
After the electrolytic capacitor was canceled, the current input by the charger to the mobile phone was 100 Hz pulsed DC. For this reason, the 50W super flash biscuit charger uses a new charging technology-pulse charging. Compared with the traditional charging method, due to the extremely short charging gap in the pulse charging, the polarization reaction of the battery is eliminated, the loss of the battery is smaller, and the temperature change is also smaller.
In response to the volume problem of traditional transformers, the 50W super-flash biscuit charger was upgraded from a conventional transformer to a high-frequency flat transformer, and the longitudinal space was reduced by 50%. Introducing gallium nitride high-frequency switches to reduce the single energy storage requirements of the transformer, thereby reducing the size of the transformer, OPPO’s self-developed ACF (Active Clamp Flyback) control architecture achieves zero voltage (ZVS) and zero current (ZCS) switches, switches the loss is infinitely close to zero.
OPPO 110W mini flash charger
Based on the 50W super flash biscuit charger, the 110W super flash mini charger realizes high-efficiency power conversion and temperature rise control through a groundbreaking two-stage architecture. With an innovative laminate stacking and extreme structural shell material design, it will thickness is also controlled at 12mm.
In addition to being fully compatible with SuperVOOC and VOOC, 110W super flash mini charger also supports 110W PPS, 65W PD, 36W QC, covering the fast charging protocols of mainstream laptops, tablets, and mobile phones on the market.
