The Japan charger voltage and plug is diff at 100v vs 230.
Can we just use a normal adapter to charge the phone??
Or can we use an Sg iphone Charger to charge a Japan iphone??
Any 1 have similar experience??
Take a closer look at the provided Japanese iPhone charger. If its printed anywhere "100V-240V 50/60Hz" that means the charger is good internationally.
The plug head may be different but that can easily solved with a cheap US/JP-to-UK travel adapter plug.
Else you can simply use the provided lightning cable and any Anker Charger, quick charger or spend more money to buy a iPhone charger from the Apple Store or you can use your comp to charge your iPhone 11 Pro.
