Anker, the electronics manufacturer, has issued another major recall — this time involving five of its most popular charging devices. It’s the second recall the company has announced this month, affecting more than one million power banks so far, with more potentially to come. Anker says the move is being made “out of an abundance of caution.”

Despite the company's reassurances, owners of specific Anker MagGo and Anker Zolo power banks are being urged to check their model numbers immediately. According to the recall notice, the affected devices are at risk of overheating, melting, smoking, or even catching fire.

The following models are included in the recall:

Anker Power Bank (10K) – Model A1257

Anker Power Bank (20,000mAh, Built-In USB-C Cable) – Model A1647

Anker MagGo Power Bank (10,000mAh) – Model A1652

Anker Zolo Power Bank (20K, Built-In USB-C and Lightning Cable) – Model A1681

Anker Zolo Power Bank (20K, Built-In USB-C Cable) – Model A1689

Anker says the issue stems from faulty lithium-ion battery cells used in the affected models. Customers with eligible devices can file a claim to receive a free replacement or a gift card for use on Anker.com. To do so, users must submit a recall claim form along with proof of purchase.

Owners are also encouraged to properly dispose of recalled devices by taking them to an authorized electronics recycling facility, such as those available at local hardware stores like Home Depot.
