2000 w Watt Voltage Converter

I am an electrical engineer by training and work for an International Oil Company in Africa. I have a number of small step down transformers, voltage stabilizers and UPS systems in my apartment in Africa. The utility power supply to the apartment fails at least daily and the staff starts up a backup generator within a few minutes. Both the utility supply and generator are subject to large fluctuations in voltage.I was looking for a combination voltage converter and stabilizer that would provide 120 volts from the 240 volt supply and simultaneously provide stabilized 240 volts. This would be useful in the bedrooms, for example, to power a locally purchased TV that needed a stabilizer for the 240 volt supply and a US purchased Blu-Ray player and cordless phone that needed 120 volts. I also have photographic lighting equipment brought from the US that requires fairly high wattage at 120 volts. I wanted a single unit that would provide stable 120 volt power for the photographic lights and could be used for household equipment when not being used for the photo lighting.The unit that I received differs from the photo as the outlets on the front panel are black and the name on the front is "Superite" - not "Seven Star". I would have preferred the colored outlets as both the 120 and 240 volt outputs are live when the device is on. Having color coded outlets might reduce the chance of plugging a 120 volt device into the 240 volt output. What appears to be the same item is available from Amazon with different names but probably all come from the same supplier in China.Upon receiving the converter, I did some preliminary testing to confirm functionality and then took the cover off the housing to exam the build quality and circuit design. Typical of cheap Chinese electrical equipment, the hand soldered connections did not look very good but everything worked OK. The converter and stabilizer is of fairly conventional design with a laminated core transformer, voltage sensor circuit and relays to select taps on the transformer to provide the regulated output. Upon sensing an out-of-range condition on the input voltage, a relay selects another tap on the transformer to correct the output voltage. The click that the reviewer of another listing for this same item found annoying is actually an indication that the unit is working - a relay clicks each time an adjustment is made for the input voltage fluctuation.My overall impression is that the unit functions as advertised and is a good value for the money. If it continues to function properly, I will purchase one or two more on my next trip back to the US in two months.

I used this device on multiple 220V equipment and non of them worked as they should be. they were all below 2000W power.I used on on a Kenwood food processor (2000W) and it went turtle speed. i used it on a 600W drill, it couldn't even drill a gypsum board, i also used it on a 1200W vaccume machine and there was no suction power at all.it is so heavy and not easy to carry from one place to another, i always had the fear that the handle will break and it will fall on my feet. i do not recommend this device to anyone.

This unit has met all my expectations. I'm currently in Afghanistan and I needed a voltage converted with enough Watts to handle my US power specification espresso make. This coffee machine requires a very high amount of power to work (1300 Watts) so I needed to find a transformer that can handle that. I also have another 110V device connected to the unit which only requires 220 Watts. I can keep this unit on conituosly with both appliances plugged in and have not seen any spikes or drops in power which I'm very thankful for. I would highly recommend this unit to anyone looking for a solid transformer to plug your US made 110V appliances.

I picked this product because I am deployed overseas and I wanted to protect my high end electronics from bad unreliable electricity. I plugged it in put in my high end TV and immediately heard the converter clicking which means its making automatic voltage adjustments to provide clean reliable output voltages. The product is amazing I'll be ordering 3 more.

Thanx!

ABSOLUTELY AWESOME!
