Step down transformer , input=220-240volt & output=120volt

Any opinions on the below type of transformers, are they decent quality ?





Sears.com

I am going overseas to South Asia(Sri Lanka) for a short while , and while there I need to help renovate family ancestral home so taking some 120V American power tools with me. Voltage in Sri Lanka is 220-240Volt 50hz and electrical sockets are 13amps.

I need a 3.5kva to 5kva Step down transformer because the most powerfull tool I have is the 15amp Miter saw, rated at about 1850Watts.

But you saw is 60Hz. Good way to shorten the life of the saw if it even runs fast enough to cut. Of course the transformers are probably also intended for use on 60hz so that is problem #2.

Don't most, if not all handheld power tools use universal motors, which don't care about frequency or if it's ac or dc?

What power tools are you using?

You are correct. My bad. If it has brushes it will probably work okay. Thanks for the correction.

Have you given any thoughts about taking a small generator instead?
