    FAQs about Charging the battery with a low current

    What is low current charging?

    Low current charging, also known as trickle charging, is a feature found in some power banks designed to safely charge devices that require a lower current. This mode delivers a smaller amount of current (typically around 1A or less) compared to the standard charging mode.

    What happens if you charge a lithium ion battery below voltage?

    Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.

    What happens when a battery is fully charged?

    At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.

    Is it safe to charge a low-current device with a battery charger?

    It is safe to charge a low-current device with a battery charger only if it is designed to charge such devices. Most power banks are not compatible with low-current devices and treat them just like any other smartphone. This may cause them to send a high-intensity current which can damage your device.

    How does a low power charger work?

    When a low-power device is connected, the charger or power bank automatically detects its power needs and switches to Low Current Mode, delivering a smaller current output tailored to the device's specifications. This prevents overcharging, overheating, and damage to the device's battery, ensuring safe and efficient charging.

    How do I charge a lithium ion battery?

    When charging a lithium-ion battery, the charger uses a specific charging algorithm for lithium-ion batteries to maximise their performance. Select LI-ION using the MODE button.
