The 12V DC power adapter has many benefits that are quite helpful to customers. First and foremost, it will not disrupt current flows with its steady output, so sensitive electronic equipment receives fewer structural damage caused by spikes in computer data line connectors or other cable connections on TV set-top box inputs; those times when there's enough electricity but no connection to ground. Secondly, it saves on space and power (and so money). Everything nowadays consumes energy, whether it's a car, computer or air conditioner. In the future, one of mankind's great challenges will be to find ways for us all not only to enjoy our ever increasing consumption in terms of material goods, but also life and culture itself. Thirdly, because of its small size this function provides a very good answer for locations with limited space. Last of all, the transformer's rugged reliability guarantees there will be no more frequent replacements or maintenance in operating years to come. These down-to-earth benefits make a difference that is substantial for users: money is saved; conveniences are increased; and reliability is enhanced.
