What was recalled
If you have purchased a battery-powered phone case from Endliss Technology, specifically those marketed under the "Trianium" brand name, it is important to know that this specific product line has been subject to a significant safety recall. This action was taken by the U.S. Consumer Product Safety Commission (CPSC) to address serious safety concerns associated with the internal power source of these cases. The recall encompasses all models of the Trianium battery phone cases, which were designed to be compatible with various types of mobile phones rather than being exclusive to a single device model. This broad compatibility is part of why the scope of the recall is so extensive, affecting consumers across different demographics who rely on extended battery life for their daily communication needs.
The recalled items are identifiable by several distinct features. First, the brand name "Trianium" is clearly printed on the back of each case. These cases were available in four specific colors: black, gray, white, and pink. The most critical identifier for consumers is the model number, which is located on the product packaging or potentially on the device itself. There are exactly 17 different model numbers included in this recall list. If your case bears any of the following model numbers, it is part of the recall: TM000006, TM000007, TM000008, TM000009, TM000010, TM000011, TM000046, TM000047, TM000048, TM000049, TM000101, TM000103, TM-06A-4000BBLK, TM-06A-4000ROGD, TM-06A-4000WSLV, TM-S6BC-BLK, and MTS-3000-BBLK. It is crucial to check your specific case against this list, as even minor variations in the model number can determine whether your unit is affected.
Regarding the distribution of these products, it is important to note that these Trianium battery phone cases were sold exclusively through Amazon.com. They were not distributed through brick-and-mortar retail stores, third-party electronics shops, or other online marketplaces. This exclusivity helps narrow down where you might have acquired the product. The recall was officially announced on October 7, 2020. If you purchased a case from Endliss Technology prior to or after this date through Amazon, it may still be subject to this recall depending on whether it matches one of the listed model numbers. The decision to issue this recall stems from reports indicating that the lithium-ion batteries within these cases can overheat, leading to a condition known as thermal runaway. This specific hazard has already resulted in 96 reported incidents of overheating, including 10 reports of burn injuries to consumers, underscoring the necessity of identifying and removing these products from use immediately.
To confirm if you have one of these recalled items, please inspect your phone case carefully. Look for the "Trianium" branding on the back panel. Then, locate the model number, which is typically found on the side edge or inside the packaging box. Compare this number against the list provided above. If you find a match, do not panic, but do take immediate action. The fact that these were sold exclusively on Amazon means that your purchase history there can serve as a secondary verification method if you are unsure of the exact model number. However, relying on the physical markings on the case is the most reliable way to determine if your device is part of this specific safety notice. Understanding exactly what was recalled allows you to take control of your safety and seek the appropriate remedy offered by the manufacturer.
The hazard, explained
At the heart of this recall is a failure within the lithium-ion battery embedded inside the Trianium phone case. To understand why this is dangerous, it helps to look at what happens when that battery experiences "thermal runaway." In simple terms, thermal runaway is a self-sustaining cycle where a battery’s internal temperature rises uncontrollably. Lithium-ion batteries are designed to release energy in a controlled chemical reaction, but when they overheat—due to manufacturing defects, physical damage, or internal short circuits—that control breaks down.
Once the process starts, the heat generated by the battery actually causes more chemical reactions that produce even more heat. This creates a vicious cycle: the hotter it gets, the faster it heats up. Because these batteries are sealed tightly inside a phone case, there is very little room for the excess heat to dissipate safely into the air. The temperature can spike rapidly, turning the battery into a significant source of intense heat rather than just a power source.
This rapid overheating poses a direct and immediate burn hazard. The CPSC record notes that Endliss Technology has received 96 reports of batteries overheating due to this exact mechanism. While not every instance leads to fire, the surface of the case can become hot enough to cause injury. In fact, there have been 10 reported cases where consumers suffered burn injuries. These burns can range from mild skin irritation to more serious tissue damage, depending on how long the phone was in contact with the skin and how quickly the user noticed the heat.
It is important to understand that you might not know this is happening until it is too late. Thermal runaway can occur even if the phone appears to be functioning normally or charging correctly. The defect is internal, meaning external checks like looking for cracks or checking the charger won’t necessarily reveal the danger. The heat builds up silently inside the casing, often while the phone is in your pocket, on a nightstand, or being held against your body. This is why the recall emphasizes immediate cessation of use rather than waiting for visible signs of damage.
While lithium-ion batteries are generally safe when functioning as intended, this specific class of hazard highlights the risks of compact power sources in enclosed spaces. The Trianium cases combine a phone cover with a battery pack, creating a dense environment where heat can accumulate quickly if the internal components fail. By understanding that the danger comes from unchecked internal heating rather than just electrical shock, you can better appreciate why stopping use immediately is the only safe course of action.
Who is most at risk
When we look at who is most vulnerable to the hazards posed by the Endliss Technology Trianium battery phone cases, we have to look beyond just the physical product and consider how people interact with it every day. The primary group at risk includes anyone who purchased these cases exclusively on Amazon.com in black, gray, white, or pink colors, specifically those whose devices match one of the 17 model numbers listed in the recall notice. However, the nature of this burn hazard creates a specific profile of vulnerability that extends beyond simple ownership.
The most immediate risk falls on individuals who are using their phones while charging them through these cases. Because the defect involves thermal runaway—a rapid, uncontrollable increase in temperature—users are often in close physical contact with the device during incidents. This is particularly dangerous for people who habitually hold their phones against their bodies, such as tucking a phone into a pants pocket or bra, or those who sleep with their devices on nightstands near their faces or hands. If the battery fails while plugged in or actively charging, the heat generated can be intense enough to cause burns before the user even notices the device is getting hot, especially if they are distracted by media consumption or work.
Certain demographics face heightened risks due to physiological factors. Children and teenagers, who are statistically heavy users of mobile devices for gaming and social media, often charge their phones overnight or during long periods of unattended use. They may also be less attuned to early warning signs of overheating, such as slight warping or warmth, assuming it is normal behavior for a fast-charging battery. For elderly users or those with reduced sensitivity in their hands and feet due to conditions like neuropathy, the danger is equally severe but different. They might not feel the initial stages of heat buildup, allowing the device to reach temperatures capable of causing second- or third-degree burns before they have a chance to react and disconnect it.
Furthermore, individuals living in small spaces or with limited mobility are at greater risk of secondary injury. If the case ignites or leaks hot electrolyte, nearby flammable materials like bedding, curtains, or clothing can catch fire quickly. For people who rely on others for care, such as seniors needing assistance, a malfunctioning battery device poses a risk not just to them but to their caregivers who might handle the device after an incident. The 10 reported burn injuries highlight that this is not a theoretical risk; it is a physical reality for those carrying these specific Endliss models. Therefore, while any owner of the listed TM-series or alphanumeric model cases is at risk, those with slower reaction times, reduced sensation, or habits involving close-body contact with their phones are in the most precarious position.
How to tell if you have the recalled item
Identifying whether your phone case is part of this specific recall requires a careful visual inspection and a check of the model number printed on the device. Because these cases are designed to look like standard protective gear, they do not always have obvious warning labels attached at the point of sale. You need to look past the general appearance and focus on the specific text markings that confirm it is a Trianium product manufactured by Endliss Technology.
First, turn the case over and look at the back panel. The brand name "Trianium" must be clearly visible, written directly on the surface of the case. This is your primary indicator that the item falls under this specific safety notice. If the case does not have "Trianium" printed on the back, it is likely not part of this recall, though you should always exercise caution with any lithium-ion battery accessory.
Next, you must verify the model number. The recall affects 17 distinct model numbers. These are typically located near the Trianium branding or in the packaging if you still have it. You need to check your case against this exact list of identifiers: TM000006, TM000007, TM000008, TM000009, TM000010, TM000011, TM000046, TM000047, TM000048, TM000049, TM000101, TM000103, TM-06A-4000BBLK, TM-06A-4000ROGD, TM-06A-4000WSLV, TM-S6BC-BLK, and MTS-3000-BBLK. If your case’s model number matches any of these codes, it is included in the recall.
You can also narrow down your search by looking at the color and sales channel. These recalled cases were sold exclusively on Amazon.com. They came in four specific colors: black, gray, white, and pink. While color alone cannot confirm a recall, finding a Trianium-branded case in one of these colors that was purchased from Amazon makes it highly probable that it is one of the affected units.
If you are unsure about your model number or cannot find the branding, do not guess. The safest approach is to stop using the item immediately and contact Endliss Technology for confirmation. You can reach them toll-free at 844-609-0847 or visit www.trianium.com and click on the recall link on the page for more information. They can help you verify if your specific serial or model number is part of this safety action.

What can happen if you ignore it
It is easy to feel attached to a convenient accessory, especially one that extends your phone’s battery life or adds a sleek layer of protection. The Trianium battery cases are visually unassuming, coming in neutral tones like black, gray, white, and pink, with the brand name discreetly printed on the back. Because they look like standard phone cases, it is tempting to dismiss early warning signs or simply continue using them out of habit. However, ignoring this recall carries serious, tangible risks that go far beyond a simple inconvenience.
The core danger lies in the lithium-ion battery technology housed within these specific units. Unlike standard power banks that are separate from your device, these cases have their power source integrated directly into the shell you carry in your pocket or hand. When a lithium-ion battery experiences "thermal runaway," it is no longer just a minor malfunction; it is a rapid, self-sustaining chemical reaction where the cell heats up uncontrollably. This process can escalate from a warm case to a dangerously hot surface in a very short period. If you continue to use the recalled cases, you are essentially carrying an unstable heat source against your body.
The consequences of this thermal runaway are not theoretical. According to reports received by Endliss Technology prior to this recall, there have been 96 documented incidents where the batteries overheated. More concerning are the 10 reported burn injuries. These injuries likely occurred because the case was in direct contact with skin—whether held in a hand, kept in a front pants pocket, or tucked into a bra or shirt pocket during charging. Lithium-ion fires can produce intense heat capable of causing second- and third-degree burns, which are painful, slow to heal, and often require medical intervention. In the worst-case scenarios involving battery fires, these can also ignite nearby flammable materials, such as curtains, bedding, or upholstery, leading to property damage.
Beyond the immediate physical risk of burns, there is a secondary danger of unexpected failure. A battery undergoing thermal runaway may swell, leak electrolytes, or rupture its casing. If this happens while you are walking, driving, or in public, the sudden release of pressure and heat can startle you, potentially causing you to drop your phone or even lose your balance. Furthermore, if the battery ignites while charging overnight on a nightstand or near your bed, the risk expands from personal injury to home safety. You might wake up to smoke or fire, endangering not just yourself but your family and your home.
Some consumers might think that because they haven’t experienced an issue yet, the product must be safe. However, battery failures are often unpredictable and can occur even in units that have been used gently for months. The 96 reports indicate that this is a systemic manufacturing defect, not a rare anomaly. Continuing to use the case relies on luck rather than safety engineering. By ignoring the recall, you are gambling with your personal safety and the safety of those around you for a convenience that can be instantly replaced with a free, safe alternative. The peace of mind that comes from knowing you have eliminated a known fire hazard is worth far more than holding onto a defective product.
Staying safe: broader tips
While this specific recall addresses a manufacturing defect in Endliss Technology’s battery cases, the underlying issue—thermal runaway in lithium-ion batteries—is a category-wide concern that affects nearly everyone who carries power banks, wireless earbuds, or smartphones with built-in batteries. Understanding how to manage heat and charge cycles is one of the most effective ways to prevent incidents before they start. Lithium-ion cells are remarkably efficient, but they are also chemically sensitive to temperature extremes. When these batteries are charged too quickly, used while charging, or exposed to high ambient temperatures (like leaving a phone on a dashboard in summer), the internal pressure can build up faster than the safety mechanisms can vent it. This is why general consumer education emphasizes avoiding "trickle charging" scenarios where a device sits at 100% charge for extended periods while remaining warm, as this degrades the separator layers inside the cell over time.
To mitigate these risks in your daily routine, consider adopting a few simple habits regarding how you store and charge portable electronics. First, always use charging cables and adapters that are certified by a recognized laboratory, such as UL or ETL. Counterfeit chargers often lack the necessary circuitry to regulate voltage properly, which can lead to overheating even if the battery itself is functioning correctly. Second, be vigilant about physical damage. If you notice your phone case bulging, your power bank feels unusually hot to the touch during use, or your device smells like sweet chemicals (a sign of electrolyte leakage), stop using it immediately. Do not attempt to puncture or open the device yourself; instead, place it in a non-flammable container and contact the manufacturer or local waste management for disposal instructions.
Beyond individual device care, proactive monitoring of product safety is essential. The Consumer Product Safety Commission (CPSC) maintains a public database of recalls that updates daily. Subscribing to email alerts for specific brands you own or categories like "consumer electronics" can provide an early warning system. Additionally, when buying second-hand tech or refurbished items, inspect the battery health through software diagnostics if available, and physically check for any signs of swelling or corrosion on the charging ports. Finally, ensure that your home has working smoke detectors on every level, particularly near areas where you frequently charge devices. While rare, a thermal event can escalate quickly; having immediate detection and an escape plan is the ultimate layer of protection for you and your family.
- Avoid extreme temperatures: Never leave lithium-ion devices in hot cars or direct sunlight for prolonged periods.
- Use certified accessories: Only use chargers that meet safety standards (look for UL, CE, or FCC marks).
- Monitor for swelling: If a case or device back looks warped or feels loose, the battery may be failing.
- Check recall lists: Visit SaferProducts.gov regularly to see if your specific models have been flagged.
