The U.S. Consumer Product Safety Commission (CPSC) ordered the recall of approximately 11,000 HAIARA model W5 PRO external batteries due to the risk of their lithium battery exploding or catching fire, posing a threat of burns, serious injuries, or death.
The official notice published on Thursday indicates that the affected product is black, has "20W" printed on the front and "Model: W5 PRO" on the side.
This battery model was sold exclusively on Amazon by the seller Mitrytech — the commercial name of the Chinese company Huizhou Yancheng Trading Co., Ltd. — between May 2025 and September 2026, at a price ranging from 18 to 22 dollars.
How to know if your battery is included in the recall
Not all HAIARA W5 PRO units are affected. The recall only applies to those that do not have a date code in YYYYMMDD format printed on the side.
If upon checking the side of the device you find that eight-digit code, the unit is not part of the recall.
The seller's name (Mitrytech) and the brand (HAIARA) do not always appear on the physical device but are indicated on the Amazon purchase receipt.
What to do if you have a withdrawn unit
The CPSC recommends discontinuing use of the device immediately and contacting Mitrytech to arrange a full refund.
To receive it, the consumer must write the word "recalled" with a permanent marker on the battery, take a photo of it, and send the image to HAIARArecall@outlook.com, also confirming that the device was disposed of according to applicable regulations. Additional information can also be found at www.haiara.net/recalls.html.
Regarding the disposal of the device, U.S. authorities warn that lithium batteries should not be thrown in household trash or municipal recycling bins, as they can catch fire during collection or at waste facilities.
The correct approach is to take them to an electronic recycling center or to a local hazardous household waste management program.
If the battery is swollen, hot, smoking, or damaged, it should not be charged, punctured, or disassembled. If it is on fire, evacuate the area and call 911.
The scope of the problem
Mitrytech received 600 reports of fires and other thermal incidents related to the product, including three cases of burns to individuals and nine reports of material damage.
This recall adds to a series of similar alerts issued by the CPSC in the past two years against power banks sold on Amazon, including the models NEWDERY ZHX-PB22, INIU BI-B41, VEEKTOMX VT103, and Hererod PW40/EW40, all due to the same failure mechanism: lithium-ion batteries that can overheat and catch fire.
The risk of fire from lithium batteries is also a documented issue in Cuba, exacerbated by frequent blackouts and abrupt power reconnections.
According to data released in August 2026, the risks associated with improper battery use have claimed dozens of lives on the island in recent years, with thousands of incidents primarily linked to electric motorcycles.
