Accidents have occurred in battery packs manufactured by Shenzhen Ollop Technology Co., Ltd., that are installed in cordless vacuum cleaners manufactured by Dyson Limited. The products in question are suspected of having ignited while users were charging. METI would like to encourage consumers who have purchased any of the products in question to stop using them immediately.
Nature of the accident: According to the report submitted by Dyson Limited, fires occurred in some battery packs for rechargeable vacuum cleaners, which are non-genuine battery pack cordless vacuum cleaners placed and sold in online shopping malls. The products in question are suspected of having ignited while users were charging. Eight similar fire accidents have been reported as serious product accidents since March 2019, among which five accidents occurred in July 2019, showing a steep increase in the number of accidents suspected to be caused by the products in question. The details of the cause are still under investigation.
It was found that multiple brands are stamped on the battery packs in question, which were confirmed as non-genuine products during the investigation of the fire accidents. However, as the inside structures of these packs are found to be the same, these packs are suspected to be the same model sold under different brands. It was also found that a sticker indicating the company name of “Shenzhen Ollop Technology Co., Ltd.” is labeled on these non-genuine battery packs in question as a manufacturer of the battery packs.
Dyson Limited issued an alert to consumers to stop using the battery packs in question manufactured by Shenzhen Ollop Technology Co., Ltd. to prevent further fire accidents caused by the same model of the products in question.
Please check the sticker on the battery pack in your product and confirm the indication of “Shenzhen Ollop Technology Co., Ltd.” on the sticker to see if your battery pack is the same model as those found to have caused the fire accidents.
Indication of “Shenzhen Ollop Technology Co., Ltd.”
