Hi , either get ones with a solar panel of use an extension cord from your garage or window.
Yes, I know how you feel , I don't have an outdoor outlet in my new home 😕 when my husband retires and we move to the home full time, it will be one of the things I will have to do first !!!
Extension cords running in house to outside,solar lights,battery operated lights,put them on insides of all windows
Extension cord through a window or garage. When I upgraded my electrical panel, I added several electrical outlets outside and in my garage.
