Is it a bad idea to power a Pi 2,3, or zero from a mobile phone power pack?
I understand that Pi power consumption is as follows,
*** Idle *** Raspberry Pi 2 B: 420mA Raspberry Pi B+: 230-240mA Raspberry Pi B: 320-330mA Raspberry Pi A+: 180-240mA Raspberry Pi A: 120-140mA Raspberry Pi Zero: 60-70mA Raspberry Pi 3 B: 280-320mA *** Under Load/Max *** Raspberry Pi 2 B: 450-650mA Rasbperry Pi B+: 300-600mA Raspberry Pi B: 380-450mA Raspberry Pi A+: 200-300mA Raspberry Pi A: 170-300mA Raspberry Pi Zero: 120-150mA Raspberry Pi 3 B: 500-800mA
The power pack I have has ratings as follows,
If the output from the pack is 1000mA and for example the Pi zero has a max of 150mA would this power pack be too much for the Pi zero or would the Pi only pull from the power pack what ever power it needed?
So this power pack would run a pi-zero for over 14 hours or 22000/150.
I am thinking of running it headless.
