This question has been asked of European adapters, however, I am traveling to some other countries such as India, Thailand, and Indonesia. I wonder if it is safe to charge my MacBook Pro and iPhone 8 simply using an adapter in those countries.
I know most appliances these days are 110/220 dual voltage and I've had no problems charging my MacBook pro in hotel rooms in India before. However, I will be mainly staying in homes during this visit - I did some research and found out that there are commonly neighborhood "brownouts" in India and several other Asian countries which can fry your electronics. I've been trying to research my options and the best I've found is to purchase a voltage transformer with a regulator. I wouldn't even require the transformer aspect and the appliance is both expensive and bulky.
Is it safe to use my US iPhone/iPad charger with international plug adapter?
