This product is designed to maintain power bank operation by providing a consistent current draw, preventing automatic shutdown due to low or no load. It can be used for testing power bank consumption and charger performance. Most power banks automatically shut down after a few minutes when they detect minimal or no current draw, similar to when a phone is fully charged or disconnected. This module simulates a load by drawing a controlled amount of current to keep the power bank active. The module features a USB-A port with adjustable current draw settings: 25mA, 50mA, 75mA, and 150mA. Users can select the appropriate setting based on their power bank's requirements. If the power bank still shuts down, additional jumpers can be connected to increase the load. For example, connecting the 50mA setting draws 50mA; if needed, combine with 25mA or other settings until the total draw is sufficient. Maximum combined current draw is 300mA (150mA + 75mA + 50mA + 25mA). Color: As shown Material: Plastic Package Contents: 1 x Anti-shutdown module Note: Other items not included.
