Brits urged to avoid dangerous plug adaptors this summer - what to watch out for

Watch: Power adaptors fail fire resistance testing

Brits going on holiday abroad this summer have been warned to watch out for dangerous travel adaptors, after an investigation suggested thousands may be for sale online.

Consumer safety group Electrical Safety First (ESF) tested 14 products from AliExpress, Amazon Marketplace, eBay and TikTok Shop - and found they all failed to meet UK safety requirements.

It said in some instances the devices could expose users to risk of serious electric shock or electrocution.

AliExpress, Amazon, eBay and TikTok all said they had removed the products ESF flagged from sale, and that they treated product safety as a top priority.

But Giuseppe Capanna, ESF product safety engineer, urged those "heading abroad this summer to think before they buy".

"What looks like a bargain could come at a much higher cost," he warned.

Capanna also said shoppers should buy travel adaptors from trusted retailers "so they can travel with confidence".

ESF tested six regular travel adaptors and eight universal adaptors it suspected could pose safety concerns.

To be sold in the UK, adaptors must not have accessible live parts and only one set of pins should come out at a time.

But the charity found multiple sets could be exposed simultaneously in six out of eight of the universal adaptors it tested.

None of the eight met the required dimensions and mechanical strength, while some pins snapped off under force during tests.

ESF said anyone who tried to remove a broken pin from a socket would be at risk of electric shock.

The six basic travel adaptors also presented fire safety concerns in tests.

These included missing safety shutters - which protect people from coming into contact with a plug's live internal parts - missing fuses and oversized pin holes.

The Office for Product Safety and Standards has noted such concerns when issuing alerts for travel adaptors.

For instance, it recently ordered the recall of one product , external it said lacked safety shutters and rejected the import of another , external , saying it presented a serious risk of fire because it did not meet UK plug dimension requirements.
