National Trading Standards said 15,000 of the 17,000 – or nine in ten - of the gadgets it has examined since October have been detained, mainly for having non-compliant electrical components that could explode or catch fire.
With electrical items becoming more expensive it can be tempting to cut corners with dangerous copy chargers.
But with the majority of cheaper models deemed unsafe, especially while charging, you have to ask yourself – is it worth buying a substitute copy if it could destroy your home?
Always check the three pin plug on the device states its made to BS 1363 and avoid buying it if this information is missing.
Other tips from trading standards:
- Never leave the device charging unattended, especially overnight. A faulty cut-off switch or plug without a fuse - seen in many of the items - could lead to it overheating, exploding or catching fire.
- Check the shape of the plug. The first unsafe items identified often had a clover-shaped plug.
- Check for online reviews that seem genuine and for information about the company's head office and landline number. Sites that have spelling or grammar mistakes, including in the small print, can be an indication that it is not a professional operation.
- Never be dazzled by a bargain. If the price is too good to be true, it probably is.
