I am considering bringing back quite a few 110/115V/50/60hz devices to Thailand soon. We will be doing a moderate refurb on my GFs house and one will be some wiring. I have thought about installing this step up/down transformer TOPOW ST-3000 Step Up / Down Transformer (3000W) ST3000 B&H and pull lines around the house to use the 110/115v items. We plan on stocking up on a bunch of good quality kitchen appliances and I have a ton of power tools. My bigger question is it worth it or not. This unit is 3000w peak and most items would use 300w to 400w at max operation which happens infrequently. I have considered the line loss and most Romex wire it is negligible so installing it near the master panel and running wire would not be an issue.
The trade off to not doing this is buying subpar Chinese no name junk or spend big money on high-end Brand items. Most of the items available here are 50% to 75% cheaper then in Thailand.
Thoughts? Anybody attempt or do this?
