The power bank device is operable in a discharging mode in which the battery cells power the DC-to-DC converter, and the converter drives a regulated DC voltage onto the output connector. The detection circuitry detects whether a light load condition exists in which only a small amount of current is being output onto the output connector. If the condition is detected, then the converter is disabled so that current flow out of the output connector is stopped. In one example, the condition is detected by supplying a constant current onto the output connector and detecting whether the voltage on the output connector rises and stays above a predetermined voltage for a predetermined amount of time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light load detection and current drain cutoff in a power bank device","description":"A power bank device has an input connector, an output connector, a DC-to-DC switching converter, a plurality of battery cells coupled together in series, and novel light load detection circuitry.
