What happens if you leave device chargers plugged in? An expert explains

How many chargers do you own? We’re surrounded by rechargeable electronic devices – mobile phones, laptops, smart watches, headphones, e-bikes and more.

You might have a phone charger plugged in next to your bed without ever bothering to switch it off at the wall or unplugging it when not in use. The same might go for a laptop charger by your desk.
