One of which required 1500W power supply, so I thought, without reading enough about the product, that 2000W would cover my needs. After a few months, the transformer began to fail sporadically, and mostly stopped working after about 5 months. I contacted their tech support to see if there were any suggestions (I wasn't hopeful, because I was outside the return and the support windows, both.) Huang in Tech Support, however, answered immediately, explaining that they strongly recommend purchasing a transformer that supplies at least 2x your power requirements, and included the snapshot of their product recommendations. That meant it was my fault that I burned out the first transformer. Instead of leaving it at that, however, which they had the right to do, Huang offered to refund me the first purchase if I was interested in paying the cost difference to the higher 3000W model that I needed. Obviously, that is exactly what I was interested in, and so I took the offer, purchased the new model, got a refund immediately, and am powering all of my appliances again, but correctly this time! Thank you to Yinleader - both making a great product and also standing behind it. Review: Very useful - This is both convert from 110 to 220 and from 220 to 110.
