Part 3/12:

In Singapore, regulations require that power banks sold in the country meet specific safety standards, such as the IEC 62133-2 certification, which tests lithium-ion batteries against safety risks like overheating, short circuits, and other failures. Many local vendors display stickers indicating compliance, but these are not always present on the device, especially on products imported from overseas markets like Taobao or other online marketplaces outside Singapore's regulatory control.

When purchasing online or from unfamiliar sources, consumers may unknowingly buy untested or poorly manufactured power banks. Andreas Hauser, an expert in battery testing, emphasizes the importance of verifying certification labels, as untested models are significantly more likely to pose safety hazards.
