oraimo PowerNova L21 20000mAh 30W & PowerNova L11 10000mAh 22.5W Power Banks

Stay powered wherever your day takes you with the oraimo PowerNova L21 20000mAh 30W and oraimo PowerNova L11 10000mAh 22.5W Power Banks. Designed for users who need reliable portable charging for smartphones, tablets, wireless earphones and other compatible USB-powered devices, both models combine fast charging, multiple outputs, built-in Type-C cables, smart power management and advanced safety protection in a compact and convenient design.

The PowerNova L21 is the higher-capacity option, featuring a powerful 20000mAh / 77Wh battery and up to 30W maximum Type-C output. It is ideal for customers who spend long periods away from a wall socket, travel frequently or need enough reserve power to recharge multiple devices several times. According to oraimo laboratory testing, the L21 can fully charge a compatible smartphone up to approximately 4.2 times, depending on the phone battery capacity, charging conditions and energy conversion efficiency.

The PowerNova L11 offers a lighter and more compact portable charging solution with a 10000mAh / 37Wh battery and up to 22.5W maximum output. It is a practical everyday choice for commuting, school, work, short trips and general daily use. Its smaller capacity makes it easier to carry while still providing dependable backup power when your phone or accessories need an extra boost.

Both power banks support two-way fast charging, allowing them to quickly charge compatible devices while also supporting fast input when the power bank itself needs to be recharged. The PowerNova L21 supports up to 30W output and 25W input, while the PowerNova L11 supports up to 22.5W output and 20W input. This helps reduce charging time and keeps your portable power source ready for use.

For multi-device users, both models provide 2 Type-C connections and 1 USB-A output, allowing as many as three compatible devices to be charged simultaneously. This makes the PowerNova series convenient for customers carrying a phone, tablet, earbuds, smartwatch accessories or other USB-powered electronics. When multiple outputs are used together, the total output is rated at 5V ⎓ 3A, 15W Max.

A major convenience feature on both models is the built-in 29cm braided Type-C charging cable. The integrated cable reduces the need to carry a separate charging cord and is designed for everyday durability. According to oraimo testing, the braided cable is rated for approximately 10,000 bend cycles, helping provide long-term reliability during regular use.

Both the PowerNova L21 and L11 are designed with broad compatibility and can power more than 1,000 compatible devices, including smartphones, tablets, wireless earphones and other supported electronics. This makes them suitable for users with devices from different brands and helps simplify everyday charging by reducing the need for multiple portable chargers.

Battery longevity is another important advantage of the PowerNova series. oraimo states that the battery cells can retain more than 80% of their original capacity after 300 complete charge and discharge cycles under laboratory testing conditions. This represents approximately 50% more rated cycles compared with a stated industry reference of 200 cycles, helping provide more dependable long-term performance.

For added peace of mind, both models incorporate an advanced 15-layer smart protection system designed to support safe and stable charging while helping extend the usable life of the power bank and connected devices. Whether you prefer the greater endurance and faster 30W performance of the PowerNova L21 or the lighter everyday convenience of the PowerNova L11, both models offer a practical combination of portability, charging speed, multi-device support and durable construction.
