## Description

100 Watts is the maximum capacity of this transformer including the power surge. This Step up and Step down voltage converter can be used for small electronics. This continuous use transformer is capable of both up and down voltage conversions for Japan and USA electricity to enable the use of Japanese products in the USA and USA products in Japan. It converts 110/120 volt to 100V AND 100 volt to 110/120 volts, (means it will convert the American power to Japanese power and also convert Japanese power to American. Fuse protection for safety and Indicator On/Off light. Comes with 2-extra fuses.

Review: Works as described - Good quality autotransformer, silent, works as described. Weighs in at 328g so it stays plugged into a good wall outlet just fine. No ground prong, non-polarized. Does not heat up much, uses about 1.5W on its own (3.7VA) at idle (no load). The ratio seems to be 117V/100V. Although it is advertised as a 100W that's peak power, so it's fine for a small piece of electronics drawing less than that.
Review: Works for my Japanese water filter - Good item to have for using Japanese original products in USA.

Good item to have for using Japanese original products in USA.

### ⭐⭐⭐⭐ Works as described
*by A***Y on December 5, 2024*

Had an issue initially where the transformer would not power on when plugged in. Prongs were slightly bent (from handling during shipping perhaps, the packaging was minimal) and so I looked it over to see if I could find the fault. The issue was that the contact tabs for the fuse were spread too wide, causing loss of contact. Carefully pushing them closer with the fuse removed did the trick and the unit now powers on and seems to operate as it should. The fuse "carrier" is a bit flexible and can be pushed down into the body of the device, so I imagine rough handling could have also caused the fuse carrier to be pushed in too far, opening the contacts slightly and causing the fault. Still, seems a solid device aside from that initial problem.
