Having completed my first Indonesian trip this year and also electrically challenged I will share what I learned.
First there are 2 issues to consider, plug type and voltage. US appliances are typically style A or B. Other countries have different styles. For appliances that are dual voltage just purchase plug adapters. They are cheap and light. You can get a variety pack so you are covered for multiple trips to different regions. But remember you may need more than one plug unless you will only need to plug a single item at a time.
Next consideration are appliances that are not dual voltage. For these you will need a combo of transformer and plug adapter. Here too these are readily available and not too pricey or unreasonably heavy. On our trip we packed two and could have made do with one since they are multi outlets and often offer usb ports as well.
But hairdryers, curling irons and straighteners are in their own league and many power adapters will say not to use with hairdryers. Here I would use a dual voltage or better yet the dryer offered at you stay.
Several posters have mentioned special considerations for electric toothbrushes. This is new to me. I know of no issues using this with a power adapter and had no problems on my trip.
