This product is designed to maintain power bank operation by providing a consistent current draw, preventing automatic shutdown due to low or no load. Many power banks automatically turn off after a short period when they detect minimal current consumption, similar to when a phone is fully charged or disconnected. This module provides adjustable load settings to keep the power bank active during testing or charging processes.The device features a USB-A port with four selectable current draw levels: 25mA, 50mA, 75mA, and 150mA. Users can adjust the load by inserting jumpers to meet the specific requirements of their power bank. If the power bank shuts down, additional jumpers can be added to increase the load. For example, selecting the 50mA setting draws 50mA; if the power bank still turns off, adding a 25mA or other setting increases the total draw until the power bank remains on. The maximum combined current draw is 300mA (150mA + 75mA + 50mA + 25mA).Color: As Shown Material: Plastic Package Contents: 1 x Anti-shutdown module Note: Light reflection and differences in display screens may cause slight variations between the color shown in the image and the actual item. Measurement may vary by up to 1-3 cm due to manual measurement.
