As with all ACUPWR products, the AU-250 is proudly manufactured in the USA using the best materials available. This includes copper wiring that allows the unit to operate at home or work under heavy duress, and in the most heavy-duty situations. Unlike less expensive, foreign-made products using aluminum wiring, our products are designed to last for decades. Each unit is hand assembled in our factory and bench-tested at a full-load (the maximum stated wattage) to ensure years of dependability. Among the AU-250’s features is thermal protection (CTOC); the unit will turn off when overheated.

ACUPWR stands by its products by providing a lifetime warranty and insurance coverage up to $10,000. We count military and government agencies, including NASA’s Goddard Space Flight Center, among our customers for good reason: ACUPWR products are the most best-made, dependable, and long-lasting transformers available.

When considering which model ACUPWR transformer/voltage converter is best for your needs, keep in mind that our products are safe for continuous power at 120 percent beyond the stated wattage, unlike other products that adhere to an industry standard of 2-3 times higher than the appliance’s stated wattage. So, for example, an appliance rated for 300 watts of consumption would, according to the industry standard, require a 900-watt transformer. With an ACUPWR transformer, you can safely use your 300-watt appliance with a 300-watt transformer/converter; our products, remember, can handle 120-percent beyond their stated wattage handling ability.

ACUPWR recommends that you purchase our Global Surge Protector to protect your appliances from voltage spikes. Additionally, our Global Surge Protector allows you to plug in up to 6 appliances using any plug type, thus ensuring its use anywhere in the world. We also highly recommend our voltage stabilizers/line conditioners, in countries where the line voltage is particularly unstable.
