Product Description
Made by one of the leading manufacturers in the industry, the Goldsource STU series step up/down voltage transformers offer you a safe, reliable, affordable & convenient solution to converting voltages from 110-120 volts up to 220-240 volts or from 220-240 volts down to 110-120 volts for both home use & industrial applications.
The STU-3000 is rated at 3,000 watts maximum. It features a heavy-duty cord with a standard US 3-prong plug plus a free American to German outlet plug adapter. There are a total of three outputs on the front panel. Two are grounded outputs, one designated for 120 volts with a US standard outlet, the other for 220 volts only with a universal outlet. The last one is a 5V standard USB jack, a unique feature of the STU series & 1st in the industry. And most importantly, all three outputs can be used simultaneously & continuously.
For safety, it's recommended by the manufacturer that the voltage transformer's maximum power should be equal or greater than the power rating of your appliance multiplied by 1.5. For example, if you have an appliance rated at 100 watts, you will need to pick a transformer with a maximum power of 150 watts or greater.

This transformer worked excellent for 2 months, and then one day while I was brewing coffee with my expensive Cuisnart Espresso machine, I started to smell smoke from the espresso machine. I shut it down, shut the transformer, and decided to open the box and see if I can figure out the problem. I noticed a wire disconnected. After numerous emails to the seller, and numerous emails to the manufacturer, I received no replys. Today, I decided to take it to a private electrician which found out that that wire wasnt solderd properly to the system, and due to that, it took 220V of electricity, and transfered 220V straight to the Espresso machine which can is rated for 110v. My expensive espresso machine is ruined, and since I live abroad, the seller, or manufacture can care less about my concern. In my opinion, they did a poor job with the soldering in the inside of the machine. Thanks for ruining my prefectly running Espresso machine which i bought a few months ago. Stay away from this seller as his customer service lacks big time, and stay away from goldensource as they are simply cheap transformers, and their cutomer care lacks big time as well. Id be more than happy to hear back from the seller if he so decides to contact me.
