Safety Alert: Over a Million Anker Battery Packs Recalled Due to Fire Risk
In a major safety announcement, Anker has issued a recall for over a million of its portable battery packs due to potential fire hazards. The popular power bank models, known for their reliability, are now under scrutiny after reports of overheating and safety risks. If you own an Anker battery portable charger, it’s crucial to check whether your device is affected.
Why Are Anker Power Banks Being Recalled?
The Consumer Product Safety Commission (CPSC) has flagged several Anker battery packs for posing a fire risk. According to reports, certain units can overheat, leading to melting, smoke, or even flames. The recall affects specific models sold between 2019 and 2023, primarily through Amazon, Anker’s website, and other retailers.

Anker has acknowledged the issue, stating that the lithium-ion batteries in these power banks may fail under certain conditions, increasing the risk of thermal runaway—a chain reaction causing extreme heat buildup. While no severe injuries have been reported, multiple incidents of property damage have prompted this safety recall.
Which Anker Portable Chargers Are Affected?
The recall includes multiple models, with the most notable being:
- Anker 535 Power Bank (PowerCore 20K)
- Anker 537 Power Bank (PowerCore 26K)
These high-capacity battery packs were marketed as travel-friendly and fast-charging solutions. However, the defective units have raised concerns about battery safety.
If you own one of these models, check the serial number on the back of the device. Anker has set up a recall website where users can verify if their power bank is part of the safety recall.
What Should You Do If Your Anker Battery Pack Is Recalled?
If your portable charger is on the recall list, stop using it immediately. Anker is offering full refunds or replacements for affected customers. Here’s what you need to do:
- Visit Anker’s official recall page and enter your device details.
- Follow the instructions for returning the defective unit.
- Choose between a refund or a replacement—Anker is processing both options.
Since lithium-ion battery fires can be dangerous, avoid keeping the recalled power bank near flammable materials. Store it in a cool, dry place until you can return it.

How to Stay Safe When Using Portable Chargers
While Anker’s recall is concerning, battery safety is a broader issue. Here are some tips to minimize risks when using any portable power bank:
- Avoid Extreme Temperatures: Don’t leave your battery pack in hot cars or direct sunlight.
- Use Certified Chargers: Always charge your device with Anker-approved cables and adapters.
- Watch for Warning Signs: If your power bank gets unusually hot, swells, or emits a strange odor, stop using it immediately.
- Don’t Overcharge: Unplug your portable charger once it’s fully charged to prevent stress on the lithium-ion cells.
