Experts warn of data theft and safety hazards from unsafe power banks sold online
Experts warn unsafe power banks sold online can install malware, contain hidden Wi‑Fi chips and pose battery hazards; consumers urged to buy certified brands.
Smartphone users are being cautioned about the growing threat posed by unsafe power banks sold on e-commerce platforms, with experts saying these devices can carry malware, hidden wireless chips and pose physical battery risks. Two technology and cybersecurity specialists told UAE media that the problem is rising in parallel with increased reliance on mobile devices and portable chargers. Authorities and security firms are urging consumers to prioritise certified brands and adopt simple safeguards when charging on the go.
Experts describe how malware can transfer via charging ports
Imad Al‑Haffar, a technology and digital security specialist, said some low‑quality power banks can automatically install malicious software onto smartphones the moment they are connected for charging. He explained attackers increasingly exploit everyday peripherals that users consider safe to bridge into personal devices and exfiltrate data unnoticed. According to Al‑Haffar, these infections can lead to remote access, data theft and persistent breaches that remain undetected for extended periods.
Security researcher details hidden Wi‑Fi chips and keylogging risk
Global cybersecurity investigations by firms including OMG have uncovered power banks with concealed Wi‑Fi modules that can record keystrokes and transmit them wirelessly to attackers at distances of up to 90 metres. Jis Kim, a technology expert, said such hardware-level compromises enable attackers to capture passwords, messages and other sensitive input without touching the user’s phone. The hidden chips represent a more advanced threat because they do not rely on the phone’s operating system and can operate independently of device security settings.
Physical safety hazards from poor manufacturing explained
Beyond cyber risks, both experts warned that cheaply manufactured power banks pose significant physical dangers due to substandard batteries and components. Faulty cells and poor thermal management can lead to overheating, battery swelling or even explosions during charging or storage. Continuous use of inferior power banks can also degrade a smartphone’s battery health and shorten its overall lifespan, increasing long‑term costs for consumers.
Attack vectors: how USB and wireless interfaces are abused
Specialists say attackers may exploit standard USB interfaces to initiate data transfers or prompt users to install malicious files disguised as legitimate updates. Some compromised units are also designed to broadcast unsecured wireless networks that trick phones into connecting, making it easier to push malware or capture traffic. Experts recommend treating any public or unfamiliar charging device as a potential data conduit unless proven otherwise.
Consumer guidance on purchases and in‑use precautions
Security advisors recommend buying power banks only from reputable manufacturers and authorised retailers, checking for recognised safety certifications such as CE, FCC and RoHS. They also advise validating serial numbers, looking for clear product documentation and avoiding deals that appear too cheap to be genuine. When charging in public or using third‑party power banks, users should employ charge‑only cables or data blockers and enable any available “charge only” mode on their devices to prevent data exchange.
Industry and regulatory actions suggested by experts
The experts urged regulators and marketplaces to tighten controls on listings that sell unverified electronic products and to enforce testing standards for portable chargers. They also called on manufacturers to improve labelling and to provide tamper‑evident packaging that helps consumers distinguish authentic units from counterfeits. Cybersecurity firms and independent labs should continue publishing test results to raise awareness and guide safe purchasing decisions.
Consumers should keep smartphone operating systems and security apps up to date and regularly back up sensitive data to reduce the impact of any potential breach. Simple behaviours — such as avoiding charging from unknown devices, using power banks from trusted brands, and inspecting units for unusual features or heat during use — can significantly lower both cyber and physical risks. As portable chargers remain essential for daily life, combining cautious buying with practical charging habits will help users protect their data and their devices.
