OK what is this controller of made to? Is it the original (OEM/Original Replacement) controllers. a.k.a. Official Controller made by Sony, or is this the one of the rip-off Chinese made products. If it is Chinese made product, then you deserve what you pay for.
I highly discourage any imitation products (even if they're prices are too low) still the quality is down to the ground.
the charging process on PS3 controllers is done on the controller it self. PS3 console has nothing to do with it. It only throws 5v to the controller to charge it up.
