Setup, Compatibility & Care
To begin using the charger, simply connect the provided USB cable to the input port and connect the other end to a USB power source (ideally 5V/1A or higher). Insert your Ni-MH AA or AAA batteries into the slots, noting the correct polarity. To use the power bank feature, insert charged batteries and connect your device to the USB output port. For care, keep the charging contacts clean of dust and debris, and avoid using the device in humid or extremely hot environments. Always ensure you are using compatible Ni-MH rechargeable batteries to prevent malfunction.
