Question: Is this transformer guaranteed to work in China?
Document: I purchased an English-made, cordless, electric, hand pruner through Amazon, only to discover that it required 220 volt power to charge. The transformer/charger that came with the pruner would not fit any variety of US standard 220 outlet and I could not locate a source for a single plug adapter to make the tansformer/charger plug work.
There are many up/down voltage converters to consider, at a wide variety of cost and power output. Selecting one that met the modest amount of power needed to make the transformer/charger work meant that the cost was minimal, less than $30. This was my first converter and I did not know what to expect, a bit of a gamble to me.The device arrived a little worse for wear. Its own significant weight had worked against it.
Hate it does not work kills fuss as soon as it gets plugged, such a waist of money, hate hate it
Does what we needed for, (220 to 110) hoping to work as good when we take it overseas(110 to 220) .! As heavy as it is.
Bought this product after I decided to take out the the mixer/grinder we brought from India couple of years ago. Product seems to work great and thanks to all the previous reviews, I bought the one with enough wattage. My only complain would be about the weight and size of the product. It does not look great sitting in the kitchen.
I then plugged the car's 220 plung into 220 outlet on the box per the instructions. Not 5 seconds later the box started to smoke, made a loud popping sound, and shut off. Now I'm stuck with a 5 pound weight that doesnt work. The cost of shipping the box back from my current location is more than the box is even worth!!!!
Product arrived on time from Amazon. This was purchased to take on a trip to Italy, and since I'm obviously flying, weight is an issue. The product specification claims it weighs 6 pounds - real weight is more like 12 pounds. It may work fine, but for a 300 watt device, this thing is a boat anchor. I would recommend looking for something else.
I bought this product to convert my Australian 220V PAL Xbox360 to use in the U.S. Did not work for me so i returned this 300W one and have ordered a 750W. Did not work with that either so what ever. Return was simple, i just printed out the shipping label and put it back in its box and dropped it off at the UPS drop off location.For anyone that will be using it for a 220v (asia/europe/australia) xbox360, you need minimum 550W converter.
I have never written a review before, but I am so upset with this piece of junk I felt I needed to warn other buyers. While we were stationed overseas at our last assignment, I bought my daughter a barbie car that requires 220 power. Now that we have relocated to our current assignment overseas we have 110 power and I needed a way to charge the car. I figured this box wasnt too expensive and should work fine, right?
I have an amplifier and a mixer plugged to the transformer.It is compact and works very well.I did not try the USB yet.
Answer: I have no idea if it will work in China...it should but check with the company who makes it.  you need to find out what system China uses
