Did you know? A recall notice has been issued in the United States regarding handheld fans!
The U.S. Consumer Product Safety Commission issued a recall notice for handheld rechargeable fans.
On July 21, 2021, the U.S. Consumer Product Safety Commission (CPSC) issued a recall notice for about 9,780 handheld rechargeable fans imported from my country. The reason for the recall is that the lithium-ion battery of the handheld fan will overheat when charging, posing a fire hazard.
On January 8, 2021, the CPSC also issued a consumer safety warning: If the lithium-ion battery cell is separated from the battery pack and used to power the device, it may cause serious injury or death. Consumers are reminded not to buy or use bulk 18650 lithium-ion batteries.
The CPSC cooperates with major domestic e-commerce websites in the United States and plans to remove consumer products with bulk lithium-ion batteries, and handheld rechargeable fans account for a high proportion of such consumer products.
What may cause handheld rechargeable fans to overheat?
1. Handheld rechargeable fans are low-end electrical products with overly simple circuit designs and lack an effective battery management system (BMS). When the product is charging, in use, or when the internal metal parts cause an external short circuit of the battery, it is impossible to monitor and manage the temperature, current, and voltage of the lithium-ion battery, which may cause the battery to "overheat", posing a fire and explosion hazard.
2. In order to save costs, the quality of the batteries selected by the manufacturer is not high. In actual use, under environmental changes or abuse (overcharging, impact, external short circuit, etc.), the materials are very likely to undergo adverse chemical reactions, causing "overheating", leading to fire and explosion.
3. Some handheld rechargeable fans are equipped with bulk 18650 lithium-ion batteries, which have exposed metal positive and negative electrodes. When they come into contact with metal objects (such as keys and coins) carried with you, external short circuits may occur. Once short-circuited, the bulk battery may overheat and thermal runaway, causing the internal battery materials to catch fire and explode, causing personal injury.
Customs reminder:
Domestic small electronic consumer product export companies should pay attention to the US CPSC recall notice in a timely manner, strictly follow the relevant UL standards to conduct product design and safety assessment of handheld charging products exported to the United States, and improve the "thermal management" performance of such products.
Do not simplify circuit design or configure inferior batteries to save costs, which will increase the risk of recall; at the same time, do not export consumer products with bulk lithium-ion batteries to the United States to avoid losses caused by product removal.
Sellers of this type of handheld rechargeable fan should pay attention!
