As a potential customer it is clear that you will have your eye caught by one of the advantages offered by our 12v dc adapter. First and foremost, it is convenient: the device looses one of the most awkward aspects of modern living – need for four walls and an outlet. Second, it protects your electronics. The use of regulation to keep voltage constant and prevent power surges will prevent both immediate danger to fragile little parts (as sometimes happens in lightning storms or when things just go phut ) but also less-than-obvious long term hidden costs. Third, the adapter is energy-efficient. This saves on electricity costs and reduces environmental burdens. And compact size means that you carry less weight with you everywhere – making it possible to use your instrument stably even on-the-go. It even has the added benefit of being able to accompany you on your journey with any degree of comfort (or none). An essential tool for both daily and emergency uses.
