Cheaper is Not Better: Copper versus Aluminum
Why do ACUPWR transformers cost a bit more? One factor is workmanship; our products are meticulously built by hand and rigorously tested on the workbench before shipping. A second factor is parts and materials, such as the type of wiring used for our transformer’s conductivity. ACUPWR uses only copper for the primary and secondary coils, in the end making for a high-quality product that will last for decades. Contrast that with our competition, much of which is manufactured in Asia with inexpensive materials, particularly aluminum. Copper? Aluminum? What’s the difference? When it comes to electrical conductivity, it’s everything. All metals conduct electricity but some are much more efficient than others. That said, copper ranks #2 behind sterling silver...
