My house is loaded with techshit.
We have three laptops, two desktops, four cellphones, three tablets (and another under the Christmas tree), two drills and a small screwdriver, a weed eater, an electronic piano, a pencil sharpener, weather monitor center, security system, camcorder and two digital still cameras all of which are battery powered and all of which need to be recharged if they are to be dependable. SO my idea of centralizing the charging station is impractical in my home, but for most it would NOT be.
This tech shit is in addition to the normal shit: the three HDTVs, three Bluray players, two network printers, two refrigerators and one deep freezer which all draw huge amounts of power, constantly, in addition to the water heater, lighting (now a few extra Christmas lights as well) and the air conditioner/heater system, range, coffee pot, dishwasher, clothes washer and dryer, two hair dryers, four electronic toothbrushes, including a Waterpic (both kids have braces!), air purifier, multiple area fans.
All these remain a draw on the power grid and some of them draw current constantly, such as anything computery or networky or comforty (air water, etc.).
I have a lot of work to do.
