The Amass XT60 Smoke Stopper Plug is a safety device designed to protect your RC components from short circuits, reverse polarity and damage during the first power-up of a new build. It acts as a circuit breaker so a wiring fault does not turn into smoke.
It is equipped with resettable PPTC fuses, which recover automatically after an overcurrent event. The listing says this removes the risk of fire or explosion caused by faulty connections.
A visual fault indication helps you spot problems before they cause permanent damage, so the plug is described as an indispensable tool for hobbyists, drone builders and RC enthusiasts.
Smart circuit protection: PPTC resettable fuses prevent short circuits.
Reverse-polarity protection: automatically stops power flow if the battery is connected incorrectly.
Visual fault detection: an early warning system for circuit issues.
Made for first-time power-ups: safe testing of new drone and RC builds.
Wide compatibility: XT60 connectors on drones, FPV quads, aircraft, cars and boats.
Easy to use: plug it between the battery and your device.
A smoke stopper is a safety plug that limits current when you power up a new or repaired build for the first time. If there is a short circuit, the protective element limits the current and an indicator shows the fault, so you can find the problem instead of destroying an ESC or flight controller.
A resettable PPTC fuse works by increasing its resistance when too much current flows, which limits the current. Once the fault is removed and the fuse cools, it returns to normal, so it can be used again.
Always use the smoke stopper on the first power-up after soldering a new power lead, changing an ESC or replacing a power distribution board. Once the build powers up normally and shows no fault, you can connect the battery directly.
The plug does not replace careful soldering and a visual check of polarity, but it gives a valuable extra layer of protection when something has been missed.

Checking for shorts after soldering
Catching reverse polarity before damage
Safe testing of RC cars, boats and aircraft
The plug fits XT60 connectors and is used between the battery and the device under test. The page does not list a rated current or the fuse trip value, so check the seller or the manufacturer's information if you need exact protection limits.
No package contents section is shown on the page; the product is the smoke stopper plug itself.
