Charging via usb-lightning connection overseas
Is it safe to plug in my iPhone or iPad directly in to a USB outlet in a hotel overseas that uses 220v? By "plug in", I'm referring to NOT using the small white "brick charger" that one plugs in to the electrical outlet, and then plugs the USB cord in to.
I do realize that with an adapter, one can directly plug the brick in to the socket and the brick will convert to the correct voltage. However, I'm asking about removing the brick when a USB outlet exists overseas.
I can't risk frying my devices.
Thanks very much!
