Or wait till you get crushed by the pile of chargers and cables. I do not want to carry more cables with me when I travel. Yep, I am sure that a battery operated one is less powered than a wire one, but not everyone has a power socket inside their bathroom. Also, I am not a barber, so the amount pf trimming I need to do is less. My current Remington it on its last days but lasted me more than 10 years and it has a battery! I still, wonder how it managed to work for so long, probably I did not use it often enough.
