MPB21 Magnetic Power Bank

Operating Instructions
As shown in Diagram (2), attach the MPB21 to the end marked with (+) of the i Series Battery and the blue indicator will be steadily turned on. (Please recharge the battery first if the blue indicator flashes to indicate a low power.)

Battery Charging: After attaching the product to the battery, use the USB cable to connect an external power supply (e.g. a USB charging device) to the input port to begin the charging process.

During the charging process, the red indicator will flash to indicate this process.
When the battery is fully charged, the red indicator will be steadily turned on.
The max charging current is 2A.
The MPB21 is available for battery charging and USB output simultaneously. It will automatically adjust the charging current accordingly when the external power is insufficient.

USB Output: When the MPB21 is disconnected from an external power supply, it can be used as a power bank combined with a 21700 i Series Battery to charge an external USB device. After attaching the product to the battery, use the USB cable to connect an external USB device to the output port to begin the charging process.

During the charging process, the blue indicator will be steadily turned on to indicate a sufficient battery power. It will start to flash when the battery power is low. The MPB21 will automatically cease the output process to protect the battery when the battery voltage is below 3V.

Warnings:

Please ensure that the product is attached to the battery first before connecting to an external device. Otherwise the indicators will not function correctly.
The product is only functional when combined with a NITECORE 21700 i Series Battery.
When the MPB21 is attached to the battery without connecting to an external power source or a USB device, the blue indicator will be turned off automatically in approx. 40 seconds to access Hibernation Mode. Connecting to an external power source or a USB device will exit Hibernation Mode.
The product contains strong magnetic components. DO NOT put it close to objects that tend to suffer from magnetic interference.
The product will not work if attached to the end marked with (-) of the battery.
Please keep the connectors clean to avoid malfunctions due to an unstable contact.
