Oppo has expanded its portable charging lineup in China with two new high-capacity power banks, giving users more choices for fast charging phones, tablets, earbuds, and other USB-powered devices. The new models come in 15,000mAh and 20,000mAh capacities, and both focus on fast output, multi-device charging, and compatibility with modern charging standards.
The 15,000mAh Oppo power bank is the faster of the two. It uses three 5,000mAh battery cells connected in series and has a rated capacity of 8,800mAh at 5V/6A. Its biggest highlight is support for up to 80W SUPERVOOC fast charging, making it a strong option for compatible Oppo smartphones. It also supports 65W USB Power Delivery and 55W PPS, which should make it useful for a wider range of devices beyond Oppo’s own ecosystem.
For ports, the 15,000mAh model includes USB-C and USB-A, allowing users to charge two devices at the same time. When both ports are used together, the combined output reaches up to 30W. The power bank measures 125.5 x 72 x 24.8mm and weighs about 330g, making it fairly portable for its capacity and charging speed. Oppo also includes a short 20cm 8A braided cable, which doubles as a carrying strap for added convenience. Color options include Khaki Fragrance and Light Titanium.
The larger 20,000mAh Oppo power bank is built for users who want extra battery capacity for longer trips, heavy phone use, or charging multiple devices throughout the day. It uses two 10,000mAh cells connected in series, has an energy rating of 74Wh, and offers a rated capacity of 11,800mAh at 5V/3A.
This model supports up to 67W SUPERVOOC charging, 45W USB Power Delivery, and 55W PPS. While it is slightly slower than the 15,000mAh version in peak charging speed, it makes up for that with a larger battery and more ports. It includes two USB-C ports and one USB-A port, allowing up to three devices to be charged at once. However, when all three ports are active, the total output is limited to 15W.
In terms of size, the 20,000mAh version measures 121 x 72 x 31.4mm and weighs around 388g. It is available in Morning Mist Gray and Star Torch Orange, giving buyers a choice between a subtle finish and a more vibrant look.
One of the more useful features for Oppo phone owners is smart battery information through ColorOS. Compatible Oppo smartphones can display details such as remaining power, battery health, temperature, and the number of charging cycles. This gives users a clearer idea of the power bank’s condition over time, which can be helpful for long-term use.
Both new Oppo power banks have passed China’s 2026 power bank safety certification. They are also designed to charge a wide range of devices, including Apple products, making them practical options even for users who do not rely entirely on Oppo hardware.
The main difference between the two models comes down to speed, capacity, and port selection. The 15,000mAh model is lighter and offers faster 80W charging, making it better suited for users who want quick top-ups and easier portability. The 20,000mAh model provides more stored energy and an extra USB-C port, making it more useful for users who frequently charge several devices. However, its output drops significantly when all three ports are used at the same time.
Oppo has priced both the 15,000mAh and 20,000mAh power banks at 269 yuan in China, which is roughly $40. The 20,000mAh version may also be available at a discounted price of 249 yuan with a coupon, depending on the offer terms.
For now, both models are only confirmed for the Chinese market. Oppo has not announced whether the new 15,000mAh and 20,000mAh fast-charging power banks will launch internationally.
