Explain Better...

Answer 1

The person wants a Pokemon with Charge from the other Version. The easiest way to do so is to have a Blitzle from White/Black with Charge and trade it to your Black/White. If you do so, he will give a Cell Battery, an item that raises Attack when hit by an Electric move when held.

thanks

Answer 2

The guy needs a Pokemon from the other version of White/Black that knows charge. In exchange, he gives you an item.
