"Use Adapters Matching Output for Each Home Appliance" ... Beware of Explosion and Fire Risks

In an experiment conducted by the National Fire Research Institute, a wireless vacuum cleaner rated at 30V caught fire within 30 minutes when charged with a 50V high-output adapter.

[Asia Economy Reporter Jo In-kyung] When household appliances that use adapters, such as cordless vacuum cleaners, laptops, computer monitors, and electric drills, are connected to adapters with higher output than the rated adapter for the product, there is a high risk of fire or explosion.

According to the National Fire Research Institute on the 5th, there was a reported case this year where a battery exploded and caused a fire while charging a 7.4V steam cleaner using a 37.5V vacuum cleaner adapter.

Last year, there was also a case where a fire occurred due to battery overcharging when an electric scooter with a rated voltage of 46V was charged at 60V.

The Fire Research Institute conducted fire risk experiments to observe what happens when adapters are mixed and used. The results showed that when a product with a lower output was charged using an adapter with a higher rated output, the battery temperature inside the product gradually increased, and as charging continued, it overheated and caught fire.

Additionally, in products containing multiple batteries, batteries exploded one after another, causing battery fragments to fly while on fire, confirming a very high risk of leading to a fire.

An official from the Fire Research Institute said, "Adapters for household appliances should be used according to the rated voltage to prevent overcurrent or fire. Attaching tape with the name of the device used on the adapter can help prevent mixing."
