What caused the Anker & ROMOSS power bank to burn?

Global safety regulators are sounding the alarm following massive recalls of power banks from major brands Romoss and Anker. The U.S. Consumer Product Safety Commission (CPSC) and Safety Canada have flagged multiple models (including Romoss PH80, Anker 335 Power Bank [https://www.escpowerbank.com/fast-charging-power-bank/]) for overheating, melting, or catching fire during use or charging - incidents linked to catastrophic battery cell failures. This crisis exposes a dangerous industry truth: the relentless pursuit of lower prices often sacrifices safety at the altar of cheap components and lax quality control.

The Root Cause: Compromised Cells & Unverified Third-Party Manufacturing

Investigations point decisively to substandard lithium-ion cells as the primary culprit. To meet aggressive cost targets, some brands:

Source Non-Certified Cells: Using cells from unvetted suppliers lacking critical safety certifications (UL, IEC62133).

Outsource Cell Production Blindly: Contracting cell manufacturing to uncertified third-party factories with inconsistent process controls, leading to microscopic defects (dendrite growth, separator flaws).

Skip Rigorous Batch Testing: Failing to conduct destructive physical tests (nail penetration, crush tests) or deep cycle aging on incoming cells.

A power bank is only as safe as its weakest cell, warns Dr. Elena Rodriguez, battery safety engineer at PowerSafe Labs. "Thermal runaway - where one failing cell overheats its neighbor in milliseconds - is often caused by impurities in electrode materials or poor separator integrity. These defects are invisible without X-ray inspection or advanced cycle testing that many factories omit to save $0.50 per unit."

The Deadly Cost of Price-Only SourcingBrands and wholesalers prioritizing "lowest cost per unit" above all else unknowingly gamble with safety:

Inferior Cell Chemistry: Cheap cells often use unstable cobalt oxide (LCO) blends instead of safer LiFePO4 or NMC formulations. LCO decomposes violently at lower temperatures.

Counterfeit ICs: Fake charging/power management chips fail to regulate voltage/current, causing cell overstress.
