Plugging these items in at the same time can cause a fire, homeowners warned
Overloading your plug sockets with multiple electric appliances can be tempting, but just because your extension lead can squeeze in four plugs doesn't mean it's safe to do so.
Some appliances require so much power that, when grouped together, they can cause the plug to overheat and possibly start a fire. Experts are also urging homeowners to think twice about charging devices overnight, especially using USB adapters.
Fire and Rescue technical support officer Tim Benham, said: "Adaptors with several USB charging ports can get overloaded. Take care not to charge laptops or mobile phones overnight and ensure you don't plug too many items into the same adaptor at any given time.

"We advise people to buy electronic goods from reputable retailers and to stop using them immediately if their chargers are showing any signs of heating or damage."
When asked by Which? if overloaded plug sockets are a fire hazard, Tom said: "It really depends on the appliances you're plugging in. Always work out the total wattage of all the devices going into the one socket. If they add up to more than 3,000W then it's not safe - the plug in the socket can overheat and potentially cause a fire."
Surprisingly, some of the smallest appliances in our homes use the most power. A typical kettle uses around 3,000 watts - significantly more power than a fridge, even though the kettle will only be active for short durations. And an iron can use up to 720 times more power during operation than is needed for a mobile phone charger.
As a guide, you should only load one plug socket with a maximum of 3,000 watts. But it might be easier to remember the sorts of products that require more and less around the home.
A kettle can max out the socket capacity all on its own, while having your washing machine and dishwasher plugged into an adaptor would mean you're a massive 1,440 watts over the recommended amount.
Tim added: "Appliances like your fridge, radio or lamp are far more suited to sharing sockets. Take note if you're moving plugs around to try to squeeze extra devices in."
