Is it safe to charge an iPhone on a higher wattage outlet?
I'm traveling out of the country soon and I bought an adapter, but I didn't realize that it's only an adapter for the shape of the plug and not a voltage converter. I'm in the US, so our outlets are 120v, but the country I'm traveling to uses 240v outlets. Will I damage my phone or wireless headphones if I charge them without a converter but with this adapter? I'm having trouble finding information about the safe voltage limits.
