Koledzy przecież jest mowa nie tylko o ładowarce ale i o urządzeniu w telefonie (ja to rozumiem baterii innego typu) i że w teście do rozładowywania używana była dioda LED.
Eesha Khare, from California, was awarded the Young Scientist Award by the Intel Foundation after developing tiny device that fits inside mobile phone batteries, allowing them to charge within 20-30 seconds.
The device can last up to 10,000 charge-recharge cycles. (Rechargable batteries can only be recharged about 1000 times).
Unfortunately the gadget has so far only been tested on an LED light, but the good news is it worked just as it was supposed to, meaning it has a good chances of working succesfully in other devices, like your mobile phone, too.
