Incident Overview

According to the CPSC incident report (ID 5973911), on March 30, 2026, a TG90 power bank was being charged via an external cable and power adapter inside a home. Residents reported hearing a loud bang or explosion noise, followed by flames erupting from the power bank. The occupants used a household fire extinguisher to put out the fire before calling 911. The device sustained extensive damage, with one half destroyed beyond recognition and the remaining half still displaying the "TG90" marking.

The device owner noted that the charging cable used may not have been the original one supplied with the unit. The incident caused damage to household belongings, and three individuals were evaluated by medical professionals for exposure to products of combustion. The report does not specify whether the individuals required hospitalization or were treated and released.

Safety Concerns

Immediate Dangers: The explosion and fire from the power bank pose immediate risks of burns, smoke inhalation, and blast injury. In this incident, flames erupted without warning, requiring a fire extinguisher to suppress. The sudden thermal event could easily ignite nearby combustibles and cause severe injury to anyone in close proximity.

Long-Term Risks: Even after the fire is extinguished, residual heat and damaged battery cells can reignite or release toxic fumes. Exposure to combustion byproducts, as seen in this case, may lead to respiratory issues or other health effects that require medical follow-up. Damaged lithium-ion cells can also enter a state of thermal runaway hours or days later.

Property Damage Potential: The fire caused damage to household belongings, as reported. Depending on the location and speed of response, such an incident can lead to significant property loss, including damage to furniture, flooring, and potentially structural elements if the fire spreads beyond the immediate area.

Warning Signs: While the report does not mention prior warning signs, lithium-ion battery failures can sometimes be preceded by swelling, hissing, excessive heat, or a chemical smell. Consumers should watch for any deformation, bulging, or unusual heat from power banks, especially during charging. The use of a non-original cable may have contributed to the failure by delivering improper voltage or current.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: If your power bank shows any signs of swelling, overheating, or makes unusual noises, stop using it and place it in a non-flammable area away from people and combustible materials.

Do Not Attempt Repairs: Never open, puncture, or attempt to repair a damaged power bank. The internal lithium-ion battery can ignite or explode if mishandled.

Preserve the Product: Keep the damaged device and all packaging, receipts, and charging accessories in a safe place. These items may be critical evidence if you pursue a claim for injury or property damage.

Document the Incident: Take photographs of the damaged product, the scene, and any injuries. Write down the sequence of events as soon as possible. Save all medical records and receipts for property repairs.

Seek Medical Attention: If you have been exposed to smoke, fumes, or flames, see a medical professional even if symptoms seem mild. Smoke inhalation can have delayed effects.

Report to the CPSC: File a report at SaferProducts.gov to alert regulators and other consumers. Include as many details as possible about the product and incident.

If you or a loved one has suffered injury or property damage from a product failure, it may be wise to speak with a product liability attorney to understand your legal options.
