Information screen
The power bank body is made of white plastic and is equipped with a display that shows the battery charge percentage, as well as the parameters of the input and output voltage and current. The screen displays an indication of the active fast charging mode.
Three USB ports
The device is equipped with a 20,000 mAh lithium-polymer battery, with an effective capacity of up to 12,600 mAh for charging connected devices. There are two full-size 22.5 W USB ports with Quick Charge 3.0 support and one 30 W USB type C, operating on the Power Delivery protocol.
Charging connectors
The two-way USB type C interface is also used to charge the power bank itself, supporting power up to 30 W. The device also has microUSB and Lightning ports for charging. The only downside is the relatively large weight (475 g), which is offset by the affordable price of the device.
