It is possible to reduce the energy used by your MP3 charger.
Britons waste £134 million a year by overcharging phones, MP3 players and laptops. Overcharging your MP3 player can reduce the lifespan of the battery. It takes 4 hours to fully charge a MP3 player.
Electric toothbrushes, hand-held vacuum cleaners and cordless phones are also likely to zap unnecessary juice.
Spending a few minutes unplugging ten common household gadgets when they are fully charged could save around £60 a year.
