Household Solar 12V Device Charger

This in house 12v charge station is a simple solution for charging of phones and other small devices in the event of power failure.  It is derived from many similar projects here.  I used 3 12v batteries found in a used electric scooter.  They may not be the best configuration, but wired in parallel they maintain a constant charge of around 12.2v.  They are topped off by the Amazon solar panel and controller here:  http://www.amazon.com/gp/product/B005LR9IOG/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1.

I place the batteries and controller in the basement close to the window which the panel is mounted under. The output from the controller then leads up to a standard wall outlet that has been modified to accept a standard 12V plug.  It is located in the kitchen. This then can be used with any sort of adapter to power or charge small devices independent of the main electric system.
