This product can be used to keep the power bank powered on, test power bank consumption, and maintain charger functionality. It also serves as a load to draw current, preventing the power bank from shutting down due to low current draw. Most power banks automatically shut down after a few minutes when they detect no or very low current draw, similar to when a phone is fully charged or unplugged. This module maintains a consistent current draw to keep the power bank active. The device features a USB-A port, with adjustable current draw settings: 25mA, 50mA, 75mA, and 150mA. Adjust the setting based on your power bank's requirements. If the power bank shuts down, add another jumper to increase the load. For example, selecting the 50mA setting draws 50mA. If shutdown occurs, add a 25mA or other setting until sufficient load is achieved. Maximum total current draw is 300mA (150mA + 75mA + 50mA + 25mA).
