Review: Functions well under constant load - Ordered this 500 Watt transformer to use an appliance from Korea in the U.S.A. Per the manufacturer, I computed the amount of wattage needed for the appliance and then doubled it. So for example, I computed that my appliance required 210 watts, so I doubled to 420 and rounded up. The appliance I have (from Korea) didn't specify the wattage using "Watt" or "W", but instead said "VA". I believe this is the same or equivalent, but you should check with a qualified electrician if this is the case with your appliance. If your unit shows just Amp or Voltage, you can multiply the two to arrive at Wattage. Again, check with someone who is qualified before using the appliance or ordering a unit so you can ensure you get the correct wattage. My calculations worked well and the appliance has functioned without problems under constant load the entire time without issues at the selected wattage. My understanding is that you'll want to double the wattage due to changes in the flow of electricity and the appliance's peak demands that could exceed the normal wattage used or identified on the back of the appliance. Be careful for laser printers or microwaves (and other high wattage appliances), I believe that can have peak watt use of much greater than their rated wattage. I believe the rule of thumb is to multiply by 3 instead of 2 to arrive at the wattage of transformer you will need. If you live in a country that has inconsistent power delivery, you may consider purchasing a separate unit that regulates the voltage. Some transformers have this built in, but this one does not. If you will be using this transformer in the U.S.A. on a modern electrical circuit, you probably do not need a regulator. I did not purchase one and have had no trouble in the month of so that I've used the unit. The transformer does get warm to the touch, but does not get hot. I expect to unplug and turn off this transformer during vacations and while away from the home for a long period of time, but I believe that this should function well under constant load indefinitely. When you plug in, make sure you select the correct voltage on the back as the removable plug should represent the SOURCE voltage of the electricity that you will be plugging the transformer INTO. In my case, I was using a 220V appliance in the U.S.A. (110V) so I selected 110V on the back and plugged the appliance into the 220V plug on the front. For some reason, I found this a bit confusing so make sure you read the instructions included with the unit. This transformer comes with a quality plug converted for U.S. style plugs (110V) to the European/Asian style (220V) which is useful if you travel internationally and have a dual 110/220V appliance (like cell phones, laptops, etc.). It may come in helpful if you need to convert plugs for the appliance you'll be using with the transformer. In general, the unit feels like it's well made and will be able to withstand a long period of consistent use. The transformer I received was cosmetically damaged during shipment (one corner bent and a few scratches). However I'm hiding this transformer behind some kitchen items so it's not a beauty contest. The unit held up well to shipment and I didn't think the scratches and bent corner warranted a return. As far as the value of the unit is concerned, I'm very pleased with the purchase. This unit appears to be quality and will last quite a while. It was less expensive than similar units and was available for delivery with desertcart Prime. The unit includes a 3-year warranty. With this transformer being used under a constant load 24/7 almost every day, I'm comfortable that all the quality issues with the unit should come out in the first 3 years. Overall: good value, quality unit, and fast free delivery with desertcart Prime. Recommended!
Review: Excellent converter — works perfectly with our European coffee machine! - This converter has been a lifesaver for us. We brought our coffee machine from Europe to the U.S. a few years ago, and thanks to this transformer, we’ve been able to use it every day without any issues. The quality has been great so far, and it hasn’t let us down at all. We’re still enjoying our machine just like back home. Highly recommend!
