Are usb mobile charger the same.?

Guys..i have just purchased micromax canvas 2 plus mobile..and the thing is ..that usb charger is not separate... i mean when i want to charge the mobile i have to plug the usb cord into the charger adapter and plug into the socket..and the same usb cord when i have to transfer any files from pc to mobile i have to discoonect the cord from the adapter and then connect to the pc ..but the wire is little short...and another thing is that i have a LG GD510 mobile that too have a usb charger and
usb cord both are separetly given and the wire is also long...so can use the LG gd510 usb charger
and usb cord for micromax..and also both LG and Micromax usb slot are same..Thank you.

you can give a try. But i dont think it will work since both are different companies
