Those gadgets are sold more cheaply than it would probably cost you to build one.

The charger characteristics will depend on the characteristics of your mobile battery. You need to specify the output voltage and current quoted on the mains charger intended for that particular mobile.

We have no idea what your mains charger spec is! You need to specify the output voltage and current quoted on the mains charger intended for that particular mobile. Look at its label and tell us what info is there.

As suggested, you're not telling us what you need, but this 'might' do the job, or be modified to do it:

@Nigel Goodwin:nothing bro...till sterday i studied electronics theoretically...but 2day i have started studying them in practical...so i selected this basic project..im not genius to handle all the electronic devices...i want to know where to use the particular device..(for ex resistor for minimizing current ,diode to convert ac to dc)..help me

If you to are not able to understand the suggested circuit then your first step is to google for on-line tutorials about the basic electronic components, the symbols for them, and how they are used in circuits. Until you have that knowledge you are unlikely to be able to follow any advice given in this forum.
