I brought over a couple of power converters from the US  I used one with my crockpot from the US and it work OK. The other I was going to use in the garage for my battery chargers for my cordless tools. I plugged it in, check with a meter and it showed 110v so I plugged in one of my battery chargers and the charger went pop and is dead. I opened it and the fuse looks good so I don't know what popped. I checked it again with meter and it shows 110v so I am totally lost. Just ordered a better converter from Lazada hope it works.

 

 

Lazada has many power converters (transformers) to choose from. I have brought many 110v appliances to Thailand and learned a few things along the journey. First, you need to buy a power converter strong enough to handle the amperage. For example, I bought a power converter on Lazada that could handle 5 amps, which matched my paint spray gun specs. But it failed within a week. One must take into account the "start up" amps which spikes every time you turn something on.  First, know your amperage requirements, then buy a transformer that can handle double that.
