Chinese manufacturers have been at the forefront of charging technology over the past five years, and this is especially true for OPPO and its VOOC/SuperVOOC charging solutions. The VOOC standard was introduced back in 2014 and went up to 20W (5V/4A). It was licensed as Dash Charge by OnePlus, and over the years we’ve seen the emergence of 30W, 50W, and 65W charging technologies.
Today most of the phones in the BBK portfolio use the 65W standard by default, which works at 10V/6.5A. OPPO also has 80W charging technology limited to select devices, and the brand unveiled its 150W charging solution earlier this year, already available on some devices like the Realme GT Neo 3.
Since OPPO uses a custom charging solution, all phones come with a SuperVOOC charger by default. And while being able to fully charge a battery in just over 30 minutes is great, the biggest problem with OPPO’s bundled phone chargers is that they tend to be massive. Although the brand started using gallium nitride (GaN) technology to reduce the size of their chargers, they weren’t very portable.
That changes with the 50W Mini SuperVOOC Charger. As the name suggests, the 50W charger is aimed at portability and has a ridiculously thin profile that doesn’t convey the fact that this is a charger at all – let alone one that goes up to 50W. OPPO says this is the world’s thinnest 50W charger, and it’s not hard to tell. The charger was first launched in 2020 and OPPO aims to bring it to global markets.
OPPO switched to an elongated design, with the charging pins tucked into the charger when not in use, further increasing portability. At 82.2mm long, 39mm wide and just 10.5mm thick, it’s pretty much the most portable charger I’ve used to date. Using it alongside the standard 65W and 80W chargers demonstrates the magnitude of OPPO’s performance, and this is one of the best USB-C chargers for portability.
Instead of the standard electrolytic capacitor, OPPO uses 100Hz pulse charging to deliver 50W of power. The charger also features a new AC-DC control panel and high-efficiency switching to manage thermals, as well as GaN internals to reduce overall size. And in another first, OPPO uses clamping diodes to minimize interference:
“The use of a new filter architecture, custom integrated inductors, optimized control algorithms, and layout and wiring strategies in the charger reduce electromagnetic interference and meet stringent reliability index requirements.”

The 50W Mini SuperVOOC Charger is designed for OPPO and related brands that use the SuperVOOC standard, but the best part is that it also works with the USB PD protocol and reaches up to 33W. That means you can charge the best Android phones and accessories with the charger, and I’ve used it with the Galaxy S22 Ultra, the Nothing phone (1) and a wide range of wireless earbuds over the course of the last month.
Here are all the performance profiles you get with the charger:
- SuperVOOC (100-240V): 30W (5V/6A), 50W (10V/5A)
- USB PD (100 – 130V): 7.5W (5V/1.5A), 9W (9V/1A)
- USB PD (180 – 240V): 15W (5V/3A), 27W (9V/3A)
- USB PD PPS (180 – 240V): 33W (11V/3A)
The charger isn’t particularly useful in the US, as it only goes up to 9W via USB PD, and it’s a moot point anyway since OPPO is unlikely to officially sell it in the country. But the fact that it delivers 27W fast charging via the PD standard and 33W with PPS makes this an extremely enticing option for most global markets.
As you can imagine, the charger does a great job with SuperVOOC devices like the Find X5 Pro and OnePlus 10 Pro, and while both phones use the 80W standard, it doesn’t take significantly longer to charge either battery with these 50W full charge load.
But what makes it a standout option for me is the fact that it works with the USB PD protocol; It’s a great portable alternative if you’re using Galaxy A series phones, the S22, or other devices like the Phone (1) that don’t come with an included charger.
The 50W Mini SuperVOOC Charger costs around $55 in China, and while OPPO hasn’t shared any details on when it will debut outside of the country, it shouldn’t be particularly long.
