Anker Innovations Initiates Global Voluntary Recall
for Select Power Banks
Choose Your Region or Country for This Recall

Earlier this year, Anker implemented a series of enhanced quality assurance protocols designed to detect manufacturing issues earlier in the production cycle. These safeguards—including expanded component-level audits and supplier testing—helped us identify a potential issue with common, lithium-ion battery cells from a single vendor.

While the likelihood of malfunction is considered minimal, out of an abundance of caution, we have decided to initiate a voluntary global recall of several Anker power bank models. We have formally notified and are coordinating with regulatory authorities in all regions to ensure the recall is conducted in compliance with all applicable local guidelines.

The following products may be affected:

How to Tell If You Have an Affected Power Bank

Step 1: Check your model number—located on the bottom or side of your power bank.
If it matches one of the following models (A1257, A1647, A1652, A1681, A1689), proceed to Step 2.

Step 2: Verify your serial number or submit your proof of purchase using our online recall form: http://www.anker.com/mmrc2506-form

Note: Please carefully review the letters and numbers in your serial number, such as "1," "L," "l," "2," and "Z." Characters like "0" (zero) and "O" (letter O) are easily confused. Affected serial numbers do not contain the letters "O" or "I."

If your unit is confirmed to be part of the recall, please submit the Recall Claim form

If your product is confirmed to be affected:
- Stop using the device immediately.
- Do not dispose of the power bank until you receive confirmation from Anker that your unit qualifies.

How to Safely Dispose of Your Power Bank

After you've received confirmation from Anker that your power bank qualifies for a replacement or gift card, please dispose of the affected unit at a certified facility that accepts recalled lithium-ion batteries. Anker will arrange pick-up of your recalled power bank. Alternatively, you may ship the unit to Anker according to the recall instructions. Anker will dispose of it at our certified facility. Do not throw this recalled lithium-ion battery in the rubbish, general recycling stream (e.g., street-level or kerbside recycling bins), or in used battery drop-off boxes typically found at retail or home improvement stores. These are not equipped to handle recalled lithium-ion products like power banks.
Recalled lithium-ion batteries must be handled differently from regular batteries because they present a greater risk of fire.

Frequently Asked Questions

What is the issue with the power bank?

We identified a potential manufacturing issue involving lithium-ion battery cells supplied by a single vendor. These cells—commonly used in the consumer electronics industry—were included in five PowerCore models sold in multiple markets.
This issue was detected through enhanced quality assurance protocols that Anker implemented following a previous recall. While the likelihood of malfunction is considered minimal, we are initiating a voluntary recall out of an abundance of caution.

Can I continue using the power bank if it seems fine?

No. Even if the device appears to function normally, any unit confirmed to be part of this recall should be stopped from use immediately due to the risk of overheating, melting, smoke, or fire.

How should I dispose of the recalled power bank?

After you've received confirmation from Anker that your power bank qualifies for a replacement or gift card, please dispose of the affected unit at a certified facility that accepts recalled lithium-ion batteries. Anker will arrange pick-up of your recalled power bank. Alternatively, you may ship the unit to Anker according to the recall instructions. Anker will dispose of it at our certified facility. Do not throw this recalled lithium-ion battery in the rubbish, general recycling stream (e.g., street-level or kerbside recycling bins), or in used battery drop-off boxes typically found at retail or home improvement stores. These are not equipped to handle recalled lithium-ion products like power banks. Recalled lithium-ion batteries must be handled differently from regular batteries because they present a greater risk of fire.

Why are there multiple recalls happening this year?

This recall is part of a broader quality assurance initiative implemented earlier this year. We've expanded component-level testing and supplier audits to detect issues earlier in the production cycle. These improvements helped us identify the affected battery cells. We remain committed to ongoing enhancements in quality and safety across all Anker battery products.
