I am building a Project where I Need to toggle between the power supplies of Adapter and a self power supply, Preferrablly an ac source which provides an UPS and stable supply without doing any harm to the board. I have seen many websites of providing a additional board to the PI, I would like to hear from the People who have used it.

Here, This will help you to provide an Unterrupted supply and can toggle between your adaptor supply and self supply(DC supply of 6V to 61V can be supplied along the board). I have personally used this board.

Cost of Strom pi 2 is a tad high but the StromPi 2 provides up to 3A of power which will be sufficient to supply even larger devices with enough power. It also has a reset function for the Raspberry Pi, which cleverly expands the UPS function of the StromPi 2. I have used it for Raspberry PI 2 Model B.

Data Sheets and requirements are also provided in the site.


Most easy way is to use a dumb USB battery pack. But this does not notify your Raspberry PI when there is a power loss. You really need a proper UPS which is connected with an USB cable running apcupsd.
