Thank guys for you help...
I bought one from the market... Its a 2 in 1 cable.. One cable with two output/input ( whatever.. Don't know what to call it) .. It got a charger head and a PSP Usb pin.... I saw the actual charger too but shopkeeper advised me to buy the 2 in 1.. Now I can charge the PSP with my laptop and also use the cable to copy games and all .... And luckily I have an Xperia phone which has a charger with usb pin for charging.. I connect the PSP cable to the Xperia Charger and charge my PSP too.
