This charger works. Its orderly provision of electrons to the telephone is clear; I'd say even indisputable.Sure, I've had other chargers before. And those chargers worked satisfactorily. They supplied an electrical flow, of given specifications defining current, voltage and frequency, to the device whose energy requirements they could satisfy. Whether they be telephones, MP3 players, batteries, computers, cameras or sundry other of the myriad energy-consuming portable contraptions whose presence and activity have suffused the public spaces of contemporary society, and that have changed our conceptions and practices of social interaction, information retrieval and intertextual narration, those devices absorbed the energy they needed from their respective chargers, and then went on to perform their intended functions.And then this charger arrived.It came in an unassuming box, and an investigation of the accompanying literature made clear that there was, in the end, only one way this charger was likely to be used. Upon accepting the tightly defined boundaries of the charger's identity -- its proclivity to perform only a single action, but to do so in a way that was adequate to achieve the evident goal -- I was ready to proceed with the device's inaugural employment.Plugging this AC-3U travel charger into the wall, and then proceeding to plug it, in turn, into the phone, confirmed my expectations that it was capable of fulfilling the tasks that I had set for it. The electrical current seemed to flow into the phone, and the phone in turn accepted the current while visually confirming such, along with the progressive charging of the battery.It was then that things were clarified. This charger works.
