American-Made Quality

The AJ-1800EUD and all ACUPWR voltage transformers are manufactured in the USA with premium components that include copper wiring and silicon steel cores. All of our products are assembled by hand and bench-tested well beyond their stated wattage to ensure safety, reliability, and years of service.


No 2x the Wattage Rule!

With ACUPWR voltage transformers, there’s no need to buy a transformer with more wattage capability than you need. Our products work continuously as stated in their wattage. Unbelievably, you can’t do this with our competitors; the rule of thumb when buying a foreign-manufactured voltage transformer is to buy two-times the wattage you actually need. Therefore, if your microwave requires 500 watts, our competitors will suggest buying 1000 watts. Why? Because the transformer they actually label as “500 Watts” will stop working well before it reaches its wattage limit due to poor construction and quality. With ACUPWR, you can buy what you need!


Goes Above Stated Wattage if Necessary

The ACUPWR AJ-1800EUD can operate at 20-percent beyond its stated wattage IF NECESSARY, such as in the event of a power surge or inrush voltage. In such an instance, It’s nice to know that that wattage “cushion” is there. Please note that we don’t recommend using an appliance with wattage requirement that is beyond what’s stated on the transformer. (Doing so can void the warranty.)


Thermal Protection (No Fuses!)

ACUPWR voltage transformers use a thermal protection circuit that detects excessive heat caused by an overload. The circuit automatically turns off the transformer and restarts the unit when it has returned to normal operating temperature.  


Lifetime Warranty and Customer Support

The AJ-1800EUD and all ACUPWR transformers come with a lifetime warranty and continuous customer support. We encourage our customers to contact us with any concerns or questions about our products. Our response is timely, courteous, and supportive.


Versatility and Dependability

ACUPWR’s AJ-1800EUD and all of our transformer models can be used in any interior setting and environment, whether it’s your bedroom, a garage, a manufacturing space… wherever. They’re built like tanks and can handle dust, heat, and moisture, and they’ll keep chugging along—quietly!—under heavy duress.
