American-Made Quality

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


Goes Above Stated Wattage If Needed!

The ACUPWR AJD-1800 will operate at 120-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

The ACUPWR AJD-1800 uses a thermal protection circuit instead of fuses. This circuit 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 AJD-1800 and all ACUPWR products 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 AJD-1800 and all of our voltage 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.
