The apparent electrocution of a young woman wearing headphones has prompted a warning to consumers from authorities against buying cheap, unapproved USB chargers or adaptors.

The woman was allegedly wearing headphones and holding a laptop when she was found dead with burns to her head, ears and chest on the NSW Central Coast.

Fairfax reports the woman is mother of two Sheryl Anne Aldeguer who was from the Philippines and due to start work as a theatre nurse at Gosford Hospital. 

She had been in Australia for six-months while converting her nursing training to Australian standards and hoped her Manila-based family would be able to join her.

A report is being prepared for the coroner after the 28-year-old’s body was found in a home in North Gosford on April 23, police say.

Officers from Brisbane Water are investigating the circumstances.

NSW Fair Trading Commissioner Rod Stowe said there was a “real and present danger” with electrical items that are not approved to Australian standards.

“We’ve been trying to hammer that message for some time, but I suppose this is a bit of a wake-up call,” Mr Stowe told AAP.

He warned people not to be tempted by cheap, replica products.

“These devices pose a serious risk of electrocution or fire,” he said.

“With electrical items, you don’t get much of a second chance.”

Fair Trading NSW says a number of unapproved and non-compliant USB style chargers, travel adaptors and power boards had been removed from a shop in Campsie, in Sydney’s west.

The Campsie trader faces fines of up to $87,500 and two years’ imprisonment, meanwhile a corporation can be fined up to $875,000.

Consumers who have already bought unapproved and non-compliant USB-style chargers, used to charge phones and tablets, are advised to bend the pins on the chargers and throw them away immediately.

Anyone with information about unapproved and non-compliant electrical or gas products should contact Fair Trading on 13 32 20.
