Hey there,
I plan to build one portable mobile phone charger. This is because my handphone always runs out of battery and when I need to use my handphone, the battery is empty. So I plan to build this to be used when in emergency case.
Can anyone suggest to me how to build one ?
Is it ok to just use the simple concept of Vin = 9V, Vout=5V from 7805 then use to charge my handphone ? I am using Nokia 5800 XM
Thank you
