Why Good-Quality Steel Makes a Difference in Voltage Transformers

When it comes to high-quality step up and step down voltage transformers, parts isn’t just parts. Rather, it’s the ability for a transformer to work safely under extreme conditions and without energy loss that is the measure between a model that is safe, reliable, and efficient and one that can be outright dangerous.   We noted in a recent blog how the use of copper wiring for our transformer’s primary and secondary coils enables superior electrical conductivity and performance over the aluminum wire used in low-quality, inexpensive, foreign-made transformers. With this blog entry, we will discuss the importance of the transformer’s core and the need for high-quality electrical steel toward the goal of creating a safe, highly efficient transformer. To...

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...

ACUPWR Introduces the AB Power Booster Series

What do you do when you relocate to the United States, Canada with a high-end European refrigerator model that operates on 220-250 volts and 50 Hz. Of course, AC voltage in the USA, Canada, Taiwan and other countries is 110-120 volts and 60 Hz? The motor in your luxury Gaggenau, Liebherr, Miele, Sub-Zero, or hip-looking SMEG refrigerator might need as much as 250 volts and 50 Hz AC to work efficiently and without burning out. [Note that using a 60-Hz electricity for a high-power 50-Hz motor results in that motor turning too slowly and eventually burning out. (The opposite holds true when using a 60-Hz motor with 50-Hz AC.) And when that motor is used in an appliance such as a refrigerator...

Which Voltage Transformer/Converter Do I Need?

  It's not uncommon for travelers and expats to bring electronics and appliances with them when they travel or move overseas. Still, it's not as easy as packing these items up and sending them across the pond; there's a dilemma involved--one that keeps ACUPWR in business. Simply, we solve international voltage differences with our voltage transformers/converters so a 120-volt microwave oven  can work safely in a country that uses a 220-240 volt standard.    ACUPWR's line of voltage transformers/converters are available in different wattage sizes, from 100 watts to 2500 watts, and they'll accommodate the wattage consumption of most consumer appliances and electronics. Still, consumers aren't experts about things like wattage and voltage, nor should they be.    Toward that end we've provided...

A Word About our Warranty (And Using Non-ACUPWR Global Surge Protectors with ACUPWR Transformers)

ACUPWR products are built to last for a lifetime. This is not only true of our voltage transformers and converters, but it extends to our plug adapters, voltage stabilizers, and global surge protectors. Still, we can’t say the same about the quality of our competition. And with regard to global surge protectors specifically, they’re often cheaply made with sub-par surge protection components. Further, many people use inferior surge protectors to distribute 220-240-volt electricity while the unit is designed for only 110-120 volts.   ACUPWR’s AS6WWK Global Surge Protector is designed to handle 100 to 240 volts and 50 or 60 Hz. Moreover, it features such as as angled universal inputs and up to 720 joules of surge suppression while shielding...
