A consumer investigation by Which? finds that some phone chargers sold by Amazon, B&Q and eBay pose electric shock and fire risks. According to reports, Which? tests a range of chargers purchased from these retailers and concludes that several are so poorly manufactured that using them could expose people to an electric shock. The outlets also say the report identifies nine chargers that are badly made and therefore present a risk to users. One source describes the chargers as “potentially lethal,” adding that some could also overheat, with the risk of fire or other failure modes. Another outlet reports that more than half of the chargers tested are defective enough to create an electric shock hazard. The findings are presented as a consumer alert, urging customers who bought affected chargers to check for issues and follow any guidance provided by the watchdog. The reports do not specify model numbers or brands beyond the retailers, and they frame the results around Which?’s testing rather than any confirmed injuries or incidents.
