XT30/XT60 Smoke Stopper – a useful tool for drone enthusiasts. This device helps protect electronic components from current surges during initial power-up of mini quadcopters. It limits current flow in case of wiring errors or short circuits, providing early warning before damage occurs. The LED indicator glows solid green under normal operating conditions. In abnormal conditions, the LED turns off and an audible alert sounds.
