Some NRBs asked me how our 110v electronics from the US have fared in Bangladesh.
I was fortunate to find Mr. Latif of Hardy Electronics. He converted all my stereo equipment from 110v to 220v. He also built a transformer for my laser printer, and later fixed it when it was accidentally connected directly to 220V. He is amazingly competent.
Computers are not a problem because they run on 110-240.
Smaller devices (boomboxes, telephones, faxes, scanners, etc) run with step-up transformers I got in the US. You can buy them here for much less. Rule of thumb is to use a transformer with 2x the wattage of the device. So, for example, if you have a boombox that consumes 50W, you should use a 100W transformer.
Our lamps from the US were converted to local receptacles and wiring. That seems to work.
The only things that I have not figured out yet are the high wattage 110V kitchen equipment (coffeemaker etc). If anyone has an idea let me know. (And when I get that coffemaker working, I will start searching for freshly-roasted French Roast. Never a dull moment :-) )
