A DEVICE that claims to help households save money on their energy bills is “highly dangerous”, a charity has warned.

Video footage shows the devices – some for sale on eBay – exploding, risking fire and electric shock, Electrical Safety First said.

eBay said it took the findings “extremely seriously” and immediately removed the products from sale.

Electrical Safety First investigated the products after they were brought to the charity’s attention by adverts claiming that they were a way of making savings on energy bills.

South Wales Argus:

The charity bought four of the plug-in devices, which claimed to either save energy or “stabilise electrical current”.

One was bought directly from GetMotex.com and three similar devices were bought via eBay, with all four sent to an independent lab for specialist testing.

All four samples failed basic safety standards, risking fires and electric shock, the charity said.

The video footage captured during testing designed to demonstrate the product’s capability to safely handle a short circuit shows the device exploding, sending fragments of hot glowing metal into the air.

Further testing found failures with the size and dimension of plug pins, risking damage to the mains wall socket.

Energy saving claims are broadly linked to internal electronic components called capacitors which can “smooth the electrical current”.

In one of the devices tested the capacitor was not connected internally, rendering the component useless.

The findings come as consumers are urged to save energy anywhere they can to cut soaring bills.

Electrical Safety First chief executive Lesley Rudd said: “Claims surrounding energy savings will undoubtedly be more attractive to people during this time yet the devices we have tested could cost you your safety.

“Given the current climate and hardship people are facing, the safety failures present in each of these devices are even more contemptible. We urge everyone to buy from a reputable retailer that you know and trust to protect yourself from dangerous goods.”

The charity has also shared its findings with the Advertising Standards Authority over concerns about the products’ energy saving claims and with the Office for Product Safety and Standards.

An eBay spokesman said: “We take product safety extremely seriously, and welcome the information provided to us by Electrical Safety First about these products. In addition to our block filter algorithms and security teams monitoring the site, we work closely with a wide range of stakeholders to ensure eBay remains free of unsafe products.

“In this instance, our close working relationship with Westminster Trading Standards enabled the swift removal of these products through our Regulatory Portal.”

Electrical Safety First said it also contacted the seller of the unit purchased from GetMotex.com but had received no confirmation of any action taken, adding that the products remained on sale.
