Anker Recalls Select Power Banks Over Battery Cell Issue

Anker issued a voluntary US recall for select GaN power bank models after identifying a battery cell defect that can cause overheating in rare cases. The affected units include batches of the popular 733 GaNPrime hybrid charger and related SKUs sold in 2024–2025.

→ Affected model in our guides: Anker 733 Power Bank

If you own an Anker pack - especially one that lives in a hot car or stuffed pocket - stop using it until you verify serial numbers.

Affected models (check your label)

Anker’s recall covers specific manufacturing lots, not every unit sold. Commonly flagged families include:

• Anker 733 Power Bank (GaNPrime PowerCore 65W) - model A1651
• Anker PowerCore III 10K Wireless - select lots
• Anker 535 Power Bank (PowerCore 20K) - select lots

The exact list evolves as Anker updates support pages. Do not rely on model name alone - use the serial lookup tool on Anker’s recall portal.

How to check your unit

1. Find the serial number on the back label or packaging.
2. Visit Anker Support → Power Bank Recall and enter the serial.
3. If flagged, Anker provides prepaid return label and full refund or replacement - no purchase receipt required on most US registrations.

Processing times run 2–4 weeks during high-volume recall windows.

What to do while you wait

• Stop charging affected packs overnight or unattended.
• Do not gate-check lithium batteries - carry-on only when traveling with any power bank.
• Temporary replacement: our budget pick list includes Baseus 20,000mAh as a stopgap - see Best budget power banks.

Are new Anker units safe?

Retail inventory after the recall cutoff uses revised cells. Buying new from Amazon or Anker.com post-announcement is generally fine - still register the serial for warranty.

Why this matters for budget buyers

Anker dominates sub-$50 charging because reliability used to be the brand promise. Recalls happen across the industry, but lithium thermal runaway is not theoretical - verify your serial even if the pack “works fine.”
