A man has been left stunned after purchasing a supposed 120,000mAh power bank that failed to deliver the promised performance.
He discover that the device was a poorly assembled counterfeit containing just a single working battery and an unusual paste-like material resembling fufu filling the remaining internal space.
Poor performance raises suspicion
The incident has sparked renewed concern over the circulation of fake electronic accessories in the market, especially high-capacity power banks that often fail to meet advertised specifications.
According to accounts shared about the incident, the man noticed almost immediately that the power bank did not perform as expected.
Despite being marketed as a high-capacity portable charger capable of multiple full phone charges, the device struggled to sustain even a single meaningful charge cycle.
His phone’s battery drained unusually quickly after being connected, raising suspicion that the product’s claimed capacity was false or exaggerated.
Inside discovery reveals fake fill material
Growing frustrated with its poor performance, he eventually opened the device to inspect its internal components.
What he found inside was far from the sophisticated battery system suggested by its packaging.
Instead of multiple high-density lithium cells that typically make up large-capacity power banks, the device reportedly contained only one functioning battery.
The remaining internal cavity was filled with a thick, dough-like substance resembling fufu, seemingly used to give the product artificial weight and bulk to mimic a legitimate high-capacity unit.
The discovery has highlighted ongoing concerns about counterfeit electronics flooding informal markets and online platforms, where visually convincing packaging often hides substandard or outright fraudulent internal construction.
Consumers are being advised to exercise caution when purchasing high-capacity power banks, especially those sold at unusually low prices or from unverified vendors.
