The online retail giant has been forced to send out an email to millions of customers offering to replace the wall plugs for the devices after it emerged they could cause an electric shock.
Amazon told parents that the worrying fault affects two models of its best-selling Kindle Fire tablet, including a specific model designed for children.
In an email sent to customers tonight Amazon said: “We have determined that, in rare cases, when the power adapter included with the UK Fire 7″ and UK Fire Kids Edition 7″ tablet is pulled from the socket, the adapter assembly may detach and create a risk of electrical shock.”
Worried parents are being offered new chargers for free and have been warned to stop using their original adapter over safety concerns.
However, they have been told they can continue using the original USB cable attached to a computer or another generic charger to power up their tablets.
Amazon has asked customers to send back the faulty chargers and says the problem only affects devices sold in the UK and Ireland from September 2015.
“But kids these days look after all the technology themselves. She understands it better than I do.
“My daughter turns it off and on and charges it herself, so I was appalled to receive an email from Amazon warning of the risk of a potentially serious electric shock.”

“Parents are run off their feet and it’s scary to think how many people might miss this email recall – and who might have young children out there using these chargers every day at real risk of a 240 volt electric shock.”
The Amazon-branded gadgets, which are sold for £49.99 and £99.99, launched in September 2015
In an emailed response the company included a link to its website featuring the product warning and said the problem was rare.
The children’s Kindle Fire tablet was one of last Christmas’ most sought after gadgets
Last month Apple recalled some plugs for iPhones, iPads and Mac after it emerged chargers made between 2003 and 2015 and used in Europe and Australia may be at risk of breaking or causing an electric shock.
