Rechargeable batteries and ports becoming ubiquitous has been a boon for households. Case in point: we wanted lighting for our stairs like many people do. You can buy, in the single digit dollars, motion sensor lights that are rechargeable and come with magnetic and adhesive to mount the lights in the stairwell. Keep a usb fan out cable cluster nearby and recharging them once a week is a 10 second endeavor to pop the lights off the magnets in the walls and leave them plugged in for an hour. Amazing. Such a setup would have been in the hundos of dollars even 25 years ago
