U.S. Consumer Product Safety Commission issued a recall notice on handheld charging fans

On July 21, 2021, the US Consumer Product Safety Commission (CPSC) issued a recall notice on approximately 9780 hand-held rechargeable fans imported from my country. The reason for the recall is that the lithium-ion battery of the handheld fan will overheat during charging, posing a fire hazard.

In addition, on January 8, 2021, CPSC also issued a consumer safety warning: “If lithium-ion battery cells are separated from the battery pack and used to power the device, it may cause serious injury or death”, reminding consumers not to buy or use Bulk 18650 lithium-ion batteries. CPSC cooperates with major domestic e-commerce websites to plan to remove consumer products with bulk lithium-ion batteries, and handheld rechargeable fans account for a high proportion of such consumer products.

What can cause the handheld charging fan to overheat?

1. The lower end of the handheld rechargeable fan electric products, the circuit design is too simple, the lack of an effective battery management system (BMS), the product cannot be Temperature, current, and voltage are monitored and managed, and battery "overheating" may occur, posing a fire and explosion hazard.

2. In order to save costs, the quality of the battery selected by the manufacturer is not high. In actual use, under environmental changes or abuse (overcharge, impact, external short circuit, etc.), the material is prone to adverse chemical reactions, causing "overheating". Causes fire and explosion.

3. Some handheld charging fans are equipped with bulk 18650 lithium-ion batteries. These batteries have exposed metal positive and negative electrodes. When they come in contact with metal objects (such as keys, coins) that you carry with you, an external short circuit may occur. Once short-circuited, the batteries in bulk may overheat and cause thermal runaway, causing the internal materials of the battery to catch fire and explode, causing personal injury.

Customs reminder

Domestic small consumer electronics export companies should pay attention to the US CPSC recall notice in a timely manner, and conduct product design and safety assessment of handheld charging products exported to the United States in strict accordance with the relevant UL standards, and improve the "thermal management" performance of such products. Do not save money. Cost simplification of circuit design or configuration of inferior batteries increases the risk of recall; at the same time, do not export consumer products with bulk lithium-ion batteries to the United States to avoid the loss of product removal.
