## Description

This product belongs to the hot aerosol automatic fire extinguishing device. It has small size, no pressure storage tank, high efficiency and rapid start-up, and can work normally at the ambient temperature of -40°C-85°C (Fahrenheit-40°F-185°F). This product is suitable for small power distribution cabinets, communication rooms, battery compartments, car engine compartments, outdoor battery boxes and other small equipment with potential fire hazards This product belongs to the hot start type, when the ambient temperature is ≥170°C (338°F), it will automatically trigger in 1 second and provide about 30 seconds of fire extinguishing time. The size of this product is 93mm*68mm*23.7mm (3.66 inches*2.67 inches*0.93 inches), the fire extinguishing capacity is 0.3m³(10.59 cubic feet), or about 0.55m*0.55m *1m(1.8 feet*1.8 feet*3.28feet) equivalent volume This product is easy to install, and it can be firmly fixed on the surface of the object with the double-sided adhesive tape on the back or by installing the fixing screws by yourself

Review: Safety Addition in RV - I installed in my RV electrical compartment. So far it hasn't gone off, but if it needs to I sure hope it works!! I like the little piece of mind having some automatic suppression at least to buy more time to get out.
Review: Highly Recommended. Quality Built. These Will Do Their Job in the Right Situation - I will preface in saying I used to be a professional firefighter for a large department in the Washington DC area. That doesn't qualify me to speak intelligently about this item, but I did ask several former coworkers about their opinion of these and they thought they were a great idea...asked for the link. I will say the instructions state "electronic initiator valid for 10 years", and there is a 'made on' date of 6/21/2024 on all 4 that I purchased on 3/30/2025. Item is a very solid steel construction, no defects no lazy crimps, no defects in the punches or paint. Uses 3M VHB tape on the bottom...so cursory look indicates quality materials and good but simple workmanship. I can see a smaller "puck" inside and two insulated wires that appear to be about 14 gauge. Have not tested, but bought multiple so I can take one apart to see what is inside. I intend to use these inside a metal storage cabinet that stores multiple solvents. Sticking one or two onto the underside of each shelf should be sufficient. Their effectiveness will be exponentially increased if the cabinet stays closed and is relatively airtight. Bottom Line: yes, highly recommended. For $30-$40, the peace of mind should be worth it even if they inventively fail to completely extinguish suppress a blaze. I imagine they will at least buy time in a situation where stored items in a cabinet catch on fire or a charging battery overheats....the smoke detector should go off and the open flames will at least be beaten back a bit.

### ⭐⭐⭐⭐⭐ Great safety device for peace of mind
*by K***Y on 27 October 2025*

This small automatic fire extinguisher is an excellent product for extra protection in places that are often overlooked. I installed one near my car battery and another in a small power cabinet at home. It was easy to mount using the adhesive backing and feels secure. I really like that it activates automatically at high temperatures, so I don’t have to worry about checking or replacing it often. The compact size makes it perfect for tight spaces and doesn’t get in the way. It gives me confidence that small fires will be stopped quickly before they spread. A great investment for safety and peace of mind.
