20000 mAh capacity

74 Wh energy (3.7V, 20000 mAh) Powerful and lightweight Redmi Note 7, MI 9T charging 3.5x, MI 9 charging 4.5x, iPhone XS charging 4.7x.

18W two-way fast charging

The powerbank supports a maximum input charging power of 18W, both via microUSB and Type-C input. The powerbank supports a maximum of 18W output fast charging power when using a USB output port.

4 types of connectors

USB-C and microUSB input for charging. 2 pcs. USB-A output for charging up to 2 devices at the same time.

Built-in safety elements

Several types of protection serve to ensure safety, e.g. protection against overcharging, protection against overheating, protection against short circuit.

Low voltage charging

Press the battery check button twice to start low-voltage charging for 2 hours - making it easy to charge devices with low current requirements, e.g. Mi Bluetooth earphones, Mi Smart Band 4 activity monitor.

It is safe to take on the plane

Compliant with international aviation regulations, safe to bring on board.

Two-way, 18W fast charging

The Redmi 20000 mAh fast charging power bank has two USB-A output charging ports and one USB TypeC output/input, either of which can achieve the 18W fast charging function (when a compatible mobile phone is connected). The intelligent charging controller has higher charging efficiency than its predecessors, saving even more time for mega users.

THE 9-LAYER, WORLD-CLASS CIRCUIT CHIP PROTECTION

The adopted intelligent control chip and charge control ICs can safely handle certain situations, e.g. overcharge, overcurrent, overvoltage. The Redmi Powerbank 20,000 mAh not only provides nine-level circuit chip protection, but also increases charging efficiency.

Heat resistance

The heat sensor and the temperature regulator keep the cells at a normal temperature.

Short circuit protection

Automatic protection of the motherboard and cells in the event of a short circuit.

Reset mechanism

The on/off button can be used as a "reset" button in case of unstable operation.

Input overvoltage protection

The OVP circuit protects the device from overvoltage.

Protection against bad connection

It detects if the charging cable is incorrectly connected and automatically stops charging.

Output overcurrent protection

Monitors the output for current and interrupts charging if the limit is exceeded

Output overvoltage protection

It monitors the output voltage and turns off the charge when it reaches the final limit to protect the device.

Overcharge and discharge protection

We have adopted Japanese technology for this role, which prevents overcharging and discharging to protect the battery cells.

PTC cell protection circuit

The battery cells are equipped with the PTC circuit, which controls the current and provides protection when the temperature or current exceeds the permissible limit.
