INIU Power Bank Fire: What the Official Records Say

How a Power Bank Fire Can Happen

A power bank is a small, portable lithium-ion battery pack used to recharge phones and other devices. It shares the same basic fire mechanism as other lithium-ion products, from phones and laptops to e-bikes and hoverboards.

The mechanism most often described is thermal runaway: heat inside a lithium-ion cell drives reactions that make more heat, until the cell can vent, ignite or burst. Once a cell is in that cycle, the fire can be hard to stop, and it can spread to nearby cells in the same pack. The CPSC's notice uses plainer words: the battery "can overheat and ignite."

If your power bank seemed to be working normally right up until it overheated, that does not rule out a defect. Most rechargeable packs contain a battery management system, circuitry meant to watch voltage, current and temperature and cut power before a cell overheats. It is a safeguard, and it can still fail because of its design, a flaw introduced when a particular unit was built, or a component that did not work as intended. Federal regulators describe defects in those same broad terms, a point taken up below.

A device small enough for a pocket or a pillowcase can cause burns, set fire to bedding and fill a room with smoke. For someone in that position, the next questions are usually which model and serial number the unit carries and what was happening when it failed, such as whether it was charging. The site's general page on lithium battery fires covers the technical side in more depth.

Is Your INIU Power Bank Part of the Recall? What the Official Records Say

The U.S. Consumer Product Safety Commission (CPSC), the federal agency that oversees consumer product safety, published the notice "INIU Recalls Power Banks Due to Fire and Burn Hazards; Sold on Amazon", recall number 26-135, with a recall date of December 5, 2025. A recall is a public action announcing that a product carries a stated hazard and offering owners a remedy, such as a repair, a replacement or a refund.

The notice states the hazard this way: "The lithium-ion battery in the recalled power banks can overheat and ignite, posing fire and burn hazards to consumers."

The notice names the product as "INIU BI-B41 Power Banks." It describes them as INIU 10,000mAh portable power banks, model BI-B41, with a black or blue case, the INIU logo and a paw-print LED light on the front, and the model and serial number printed on the back at the bottom. It states: "Only portable power banks with serial numbers 000G21, 000H21, 000I21 and 000L21 are included in this recall." It lists about 210,000 units and a refund as the remedy, and directs consumers to INIU's recall page to verify the serial number and register for a full refund.

Under "Incidents/Injuries," the notice states: "INIU has received 15 reports of power banks overheating, including 11 reports of fires that resulted in three minor burn injuries and property damage totaling over $380,000." Those are reports the company received; a report is not a finding of what caused any particular fire. The notice lists Shenzhen Topstar Industry Co., Ltd., of China as the manufacturer and INIU, of Seattle, Washington, as the retailer, and records that the products were sold online at Amazon.com from August 2021 to April 2022 for about $18.

For you, the practical stake is the serial number on the back of the unit. If it matches one of the four listed, the notice describes your product's stated hazard and its refund. A recall, though, is not a finding that any product injured anyone, and it is not a finding that the company is liable.

If your INIU power bank caught fire but its model or serial number is not one listed, the notice simply does not speak to that unit. It says nothing about any other INIU model or serial number. Whether that unit had a defect would be a question about that product and that incident, the same as for any other device, and the product liability rules below still describe how such a question is generally approached. The site's page on the INIU recall notice covers the record on its own, and the Samsung recall records show how another recall is read the same way.

What People in This Situation Usually Gather

After a power bank fire, the first days are usually taken up with treatment, cleanup and insurance calls, and gathering anything else can feel like too much. Still, when injured people and families later look back, certain records and items tend to carry the most weight.

If you were hurt, the records that usually matter include:

• medical records and treatment documentation, from the emergency room through any follow-up care for burns or smoke inhalation;
• photographs and video of the power bank, the injuries, and the room, vehicle or bag where the fire started;
• the power bank itself, along with its packaging, charging cable and any device it was connected to;
• purchase receipts, order confirmations or account order history showing when and where it was bought;
• fire department, insurance or other incident reports;
• the names of people who saw the fire or the scene right afterward.

The device itself, even badly burned, is often the single most important physical item. The serial number on the back is what ties a unit to a recall like 26-135, and the remains of a pack can show what failed inside it. A damaged lithium-ion battery can still pose a fire risk; the CPSC notice itself says recalled lithium-ion batteries must be disposed of differently than other batteries "because they present a greater risk of fire."

None of these items decides a claim on its own. They are what tends to let the facts be shown later, when memories have faded and the scene has been cleaned.

Who May Be Responsible When Your Power Bank Catches Fire

If you were burned or your home was damaged, the law looks past the store or website where the device was bought. Product liability law can hold the businesses in a product's supply chain responsible when a defective product causes harm, and it looks at each business's role, not just at who put the device in your hands.

Those roles usually include the manufacturer that made the battery or the finished power bank, an importer that brought it into the United States, and a seller or retailer that offered it to the public. In some cases a repairer or a maker of a component, such as a cell or a charging circuit, also has a role. Which of these businesses, if any, may be responsible depends on who did what with the specific product. Nothing on this page states or implies that INIU, or any company named in the notice, fits any role in a reader's situation or caused anyone's injury.

Most product liability claims turn on one of three kinds of defect:

• a design defect, where the product's design itself is unsafe even when every unit is built as intended;
• a manufacturing defect, where a flaw was introduced during production, so a unit differs from its design;
• a warning defect, where the instructions or safety warnings were inadequate to make a product's risks clear.

Federal safety regulations describe defect in a similar way, for a different purpose. A regulation on what companies must report to the CPSC, 16 C.F.R. § 1115.4, states that "a defect is a fault, flaw, or irregularity that causes weakness, failure, or inadequacy in form or function," and that one "can also occur in a product's contents, construction, finish, packaging, warnings, and/or instructions." The federal reporting statute, 15 U.S.C. § 2064, requires manufacturers, distributors and retailers who obtain information reasonably supporting the conclusion that a product contains such a defect, or creates an unreasonable risk of serious injury or death, to inform the Commission immediately, unless they actually know it has already been adequately informed. Those rules govern reporting to a regulator; they do not decide an injury claim.

A claim generally asks for proof of a defect and proof that the defect caused the harm. For a reader, that means the questions worth weighing are who made, imported and sold the unit, and which kind of defect the facts might point to. Those are questions a conversation with an attorney can help sort out. The site's page on e-bike battery fires walks through the same three defect types for a larger battery.

Why State Law Shapes What a Claim Can Show

Product liability claims for a battery fire are generally governed by state law, not by the federal recall statute. The state where the injury happened often sets the rules that matter most, and those rules differ from state to state.

For a family managing recovery, the state's statute of limitations can matter as much as any piece of evidence. It is the period within which a claim must be filed, after which the claim is generally barred, and each state sets its own period, the event that starts it running, and the exceptions that can pause or extend it. Some states also have other deadlines, such as notice rules for claims against public bodies, and they vary too.

Fault rules differ as well. Some states reduce what an injured person may recover by that person's own share of fault, under one of several comparative fault approaches; a few apply contributory negligence, which can bar recovery where the injured person was at fault at all. If you were charging the power bank overnight or storing it in a bag, for example, how it was charged, stored or used can become part of that discussion.

The damages the law may allow are also set by state law. Depending on the state and the facts, the categories can include medical expenses, lost income, pain and suffering, and property damage, such as a burned room or belongings. Where a battery fire caused a death, many states allow a wrongful death claim: a claim brought by surviving family members after a death caused by another's wrongful act. Who may bring it, and what it may include, turn on that state's law.

Because these rules change at each state line, a conversation about the specific facts and the state involved is how a person comes to understand which deadlines and rules apply. If you would like to talk through a power bank fire with our attorney, you can request a case evaluation.
