Mi 18W Fast Charge Power Bank 3
Classic Design Becoming Even More Advanced
18W Fast Charge
Dual Port Inlet/Outlet
Lithium Ion Polymer Battery
Dual port for both Micro-USB and USB-C. Maximum input power as high as 18W;
Self-charging can be completed in 4 hours*.
Uses thermistor and temperature
regulation mechanism to ensure the
battery works within the safe
Short circuit protection
Automatically protects the main
board and battery from damage
in case of abnormal short circuits.
Added circuit rest function. In case of
faults preventing the power bank from
working properly, you can tap the
“Check Battery” button to recover.
Input over voltage protection
The OVP circuit can prevent input
over voltage to avoid damages to
the back-end circuits.
Reverse charging protection
If the cable and the Micro-USB port
are reversely plugged, the circuit will
automatically shut down to protect the
Output over current protection
Smart detection of output current
when necessary. If the output current
exceeds the upper limit, the output will
automatically be shut down to protect
the charging device.
Output over voltage protection
Smart detection of output voltage
when necessary. If the output voltage
exceeds the upper limit, the output
will automatically be shut down to
protect the device that is being charged.
Overcharge and over discharge
Added dedicated battery protection
components to effectively prevent
the battery from overcharging and
very-discharging and avoid damages
to the battery.
Hardware-level over voltage
Detects the over voltage short
circuit status of the battery at hardware
level and responds quickly to break the
current circuit and effectively protect the
