January 15, 2026 – A safety incident involving the Yissonger KT-D007 portable magnetic charger has been reported, raising concerns about potential battery failures. A consumer reported that their device expanded and cracked around the battery back, indicating a significant malfunction that could pose serious safety risks.
Product Details
Incident Overview
On December 26, 2025, a consumer filed an incident report detailing a malfunction with their Yissonger KT-D007 portable magnetic charger. According to the report, the device underwent a concerning physical change: its casing expanded significantly and subsequently cracked in the area surrounding the battery. This type of physical deformation is a strong indicator of an internal battery issue, often linked to overheating, overcharging, or internal cell failure, leading to gas buildup within the battery pack. The incident occurred without further details regarding the specific circumstances, such as whether the device was in use, charging, or stored at the time of the malfunction.
Safety Concerns
The expansion and cracking of a device’s battery casing, as reported with the Yissonger KT-D007, present several serious safety hazards:
- Immediate Dangers: Battery expansion is a critical sign of internal pressure buildup, which can precede more severe events such as thermal runaway. This process can lead to excessive heat generation, venting of flammable gases, fire, or even explosion. Such an event could cause severe burns, smoke inhalation, or other traumatic injuries to anyone nearby.
- Chemical Exposure and Burns: If the battery casing has cracked, there is a risk of electrolyte leakage. Battery electrolytes are often corrosive and toxic, capable of causing chemical burns upon skin contact and posing a health hazard if inhaled or ingested.
- Property Damage Potential: A thermal runaway event, fire, or explosion originating from a malfunctioning charger can quickly ignite nearby combustible materials, leading to significant property damage to furniture, other electronics, and the structure of a home or office.
- Who Might Be Affected: Anyone using or in close proximity to the affected charger is at risk. This includes adults, and potentially children if the device is left within their reach.
What Consumers Should Do
If you own a Yissonger KT-D007 portable magnetic charger, or any similar device exhibiting signs of swelling or cracking, please take the following immediate actions:
- Stop Use Immediately: Do not attempt to use or charge the device further. Unplug it from any power source.
- Isolate the Device: Carefully move the device to a safe, non-flammable location, preferably outdoors or in a well-ventilated area away from combustible materials, and on a heat-resistant surface. Do not puncture or apply pressure to the swollen battery.
- Do Not Dispose of in Regular Trash: Lithium-ion batteries, when damaged, are fire hazards and must not be discarded in household trash. Contact your local waste management facility or recycling center for proper disposal instructions for damaged batteries.
- Check Your Product: Verify if you own the Yissonger KT-D007 model by checking the product’s packaging or the device itself.
- Report the Incident: If you experience a similar incident or have safety concerns, report it to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
