(If that’s not bad enough, we waste £134 million a year by overcharging them: According to research commissioned by insurance provider Row.co.uk, part of the problem is overcharging which happens when users plug in their devices overnight.
A massive nine in ten owners keep gadgets on permanent charge, often unaware that overcharging batteries can reduce their lifespan, and under certain conditions lithium-ion batteries can pose a safety hazard. The figures suggest that around 85,000 tonnes of CO2 could be saved if people disconnected as soon as charging was complete.)
Average charging times:-
- Mobile Phone – 2 hours
- Laptop, with Express Charge – 2 hours
- Hand-held vacuum cleaner – 3.5 hours
- Mp3 player – 4 hours
