You can take most stuff in your carry on. Medications and chargers etc will be fine.
You can't take any fluids of more than 100ml. That includes soft solids (my son had a jar of Vaseline for his dry lips and they took that off him).
You also can't take anything that may be used as a weapon (I guess that includes the razors). So take anything like nail scissors, Swiss army knife, razors etc only in checked in luggage.
That's all I can think of at the moment.
