Encased in a premium matte black shell, the design is not only sleek but highly practical, boasting an anti-smudge texture that ensures it looks clean even after being tossed into a rucksack or carried during a dusty commute.

Furthermore, the inclusion of an easy-to-read LED indicator system allows users to check the remaining battery capacity quickly—a simple feature that vastly improves daily convenience.
Performance Mastery: 33W Fast Charging and Triple Output
The core differentiator for the Xiaomi Power Bank 4i 20000mAh is its impressive charging technology.
⚡ Blazing-Fast 33W Power Delivery
This device supports 33W Super Fast Charging via its versatile USB Type-C port, which acts as both an input and an output. For users with compatible flagship smartphones (Android or iPhone), this means significantly reduced charging times compared to conventional power banks, often topping up a phone to 50% in under 30 minutes.
Crucially, the 33W capability extends to re-charging the power bank itself. Instead of waiting an entire day, you can fully replenish the huge 20,000mAh cell in a matter of hours, ensuring it’s ready for your next adventure or potential power outage. This two-way fast charging is a massive advantage in fast-paced Indian life.
🔄 Triple Port Charging Convenience
The power bank is equipped with three output ports: two USB-A ports and one USB Type-C port. This ‘triple output’ capability transforms the device into a charging hub, allowing a user to simultaneously charge their smartphone, Bluetooth earphones, and a tablet or second phone. This level of versatility boosts productivity and eliminates the need for carrying multiple charging bricks or waiting for one device to finish charging before starting the next.
💡 Smart PD 3.0 and Low Power Mode
The integration of Smart Power Delivery (PD) 3.0 ensures intelligent power optimisation. This feature allows the power bank to negotiate the precise power required by the connected device, delivering fast charging to a high-end smartphone while safely regulating power for smaller gadgets like fitness trackers or wireless earbuds via the Low Power Mode (activated by double-tapping the power button). This meticulous safety control is central to the product’s Authoritativeness.
