American-made ACUPWR voltage transformers/converters are the best available and guaranteed not to blow up or put on a fireworks display. You might think we're kidding, but research the cheaper, Chinese-made brands; they're notorious for breaking down, catching on fire, and taking your valuable appliances down as well!Don't risk it: ACUPWR is renowned for safety, reliability, and longevity. And not surprisingly, they're used extensively by the US military, NASA, and United Nations. Our transformers and converters use premium components-copper wire and laminated silicon steel cores-and they're safe for continuous use at 120-percent beyond their stated wattage. Further, they can handle bursts of 200-percent wattage for a short period. Unlike our competition, ACUPWR transformers/converters use thermal protection, not fuses. When an ACUPWR transformer/converter is overheated, it simply shuts down, returning to operation after a few minutes.Our AUD-1000 model is a 1000-watt, step down/step up model that converts 220-240 volts to 110-120 volts and vice versa. ACUPWR provides a lifetime warranty with up to $10,000 in damage coverage for this product.
