January 15, 2026 – A safety incident involving an INIU 22.5w fast charge power bank, model BI-B61, has been reported. The power bank reportedly failed and experienced significant expansion, a common indicator of internal battery cell failure. This incident highlights potential risks associated with lithium-ion battery products and prompts an alert for consumers using similar devices.
Product Details
Incident Overview
On December 28, 2025, an incident was reported concerning an INIU 22.5w fast charge power bank, model BI-B61. The report states that the unit failed and experienced noticeable expansion. The specific circumstances surrounding the failure, such as whether the device was charging, discharging, or idle at the time of the incident, were not detailed in the report. Likewise, information regarding any resulting property damage or personal injury was not provided. Battery expansion, often referred to as “battery swelling,” is typically caused by the accumulation of gas inside the battery cells, indicating a serious internal defect or damage to the battery’s structure.
Safety Concerns
Battery expansion in power banks, particularly those utilizing lithium-ion technology, is a critical safety concern that should not be overlooked.
- Immediate Dangers: An expanded battery is at a significantly increased risk of thermal runaway, which can lead to overheating, ignition, fire, or even explosion. This risk is present whether the device is in use, charging, or simply stored.
- Long-Term Risks: Even if the expanded power bank does not immediately catch fire, its compromised integrity means it could spontaneously fail at any time. Continued use could exacerbate the internal damage, escalating the hazard.
- Who Might Be Affected: Anyone owning or using an INIU BI-B61 power bank, or similar portable charging devices, is potentially at risk if their unit exhibits signs of swelling or unusual heat. The risk extends to anyone in the vicinity of the failing device, including family members, colleagues, or pets.
- Property Damage Potential: A fire or explosion from a defective power bank can cause extensive property damage to homes, vehicles, or personal belongings. The chemicals released during a battery fire can also be toxic and harmful.
What Consumers Should Do
If you own an INIU 22.5w fast charge power bank model BI-B61 or any other portable power bank:
- Immediate Steps to Take: If your power bank shows any signs of swelling, overheating, unusual odors, or a change in shape, immediately stop using it. Do not attempt to charge or discharge it further.
- Safe Handling and Disposal: Place the compromised device in a safe, non-flammable area, away from combustible materials. Do not puncture, crush, or disassemble the battery. Contact your local waste management facility or an electronics recycling center for proper disposal of swollen lithium-ion batteries. Do not throw it in regular trash, as this poses a fire risk.
- How to Check If You Own the Affected Product: Verify the model number (BI-B61) on your INIU power bank. This information is typically found on the device’s casing or packaging.
- Prevention Measures: Always use the charging cables and adapters provided or recommended by the manufacturer. Avoid overcharging or fully discharging lithium-ion batteries frequently. Store power banks in a cool, dry place away from direct sunlight and extreme temperatures.
- Reporting Procedures: If you experience a similar incident with this product or any other consumer product, report it to the U.S. Consumer Product Safety Commission (CPSC) at www.SaferProducts.gov. Your report helps identify trends and initiate investigations and recalls.
