It is recommended to use 5V/2A charger, this allows for full usage of the raspberry pi and also devices needed for the brewing.
using a charger with higher ampere rating is fully usable etc. 5V/2,5A or more.
When the Red PWR led on the raspberry lights up, it indicates that there is accepted 5V voltage supply connected.
if the red Power low Led (PWR) blinks, it means that the voltage on the raspberry 5V is marginal below and is detected to be below 4.6 volt.
In Raspbian Operating System this low voltage indication is displayed as a yellow lightning in the top right of the screen, in order to notify the user of low voltage detected on the Raspberry 5V supply.
To avoid this warning use a charger with higher Ampere rating.
