Oppo has been spearheading the
fast-charging market in the past few years and today the company introduced the
mightiest charger for smartphones ever at 125W. At a launch event in China, we
saw three new ultra-fast charging solutions - the 65W AirVOOC wireless charge,
a pocket-sized 50W mini SuperVOOC charger, and 110W mini flash charger.
The 125W flash charge technology is said
to charge a 4,000 mAh battery up to 41% in five minutes, while it will need a
total of 20 minutes to reach 100%. In order to protect the power cell and the
smartphone, the design of the tech comes with three parallel charge pumps that
split the power, and Oppo has implemented 10 additional temperature sensors for
extra safety.
The AirVOOC wireless flash charge adopts a
circular design for better cooling, a glass panel for heat dissipation, and
“self-developed isolated charge pump technology” with parallel dual-coil design
to increase wireless charging efficiency. It operates on the same level as the
wired 65W SuperVOOC 2.0 - two coils are charged simultaneously and a full charge
of a 4,000 mAh battery should take about 30 minutes.
Currently, the charger is in its
conceptual stage, since there are no Oppo smartphones that support the
standard. The bottom of the charger comes with a cooling fan that lowers the
temperature by two degrees Celsius, and the overall design is made in such a
way to always provide a flow of fresh air.
The 50W mini SuperVOOC charger is no
bigger than a portable 4G modem. The idea is to put it in a pocket or a purse
and get on with your day, instead of having to bring around the standard heavy
power brick. It is compatible with VOOC protocols (up to 4.0 at 30W) and also
works with 27W and 50W PPS.
In order to provide proper current, the
mini charger comes with so-called “pulse charging” - Oppo removed an electrolytic
capacitor and allowed the charger to literally pump massive amounts of power at
equal time slots of 40 ms, instead of going for the traditional increase of
power throughout time.
The 110W mini flash charger has the same
idea - it is slightly bigger, but operates on the same level. It will be
compatible with all popular standards - SuperVOOC up to 65W, VOOC up to 30W,
constant output of PD at 65W and Quick Charge at 36W.
Oppo even said it could charge competitor
devices, although at limited rates - the Huawei P40 Pro at 18W, instead of 40W,
the Xiaomi Mi 10 Pro at 30W, instead of 65W, and a MacBook Pro at 65W - in all
cases charging be carried out with the original cable, provided in the retail
box.
Currently, there are over 157 million
users all over the world of the various VOOC technologies, and Oppo is
promising to keep delivering fast-charging solutions with applying for more
than 2,800 global patents on flash charging.
