Pardon my ignorance but I just can seem to find an Answer to my question and I hope that you can help me.
What is the equation for calculating how long a Lithium Battery can supply a device?
For instance a Lithium battery has a capacity of 5600mAh, and an Output of 5V 2A. The drawing device requires 350mA and 5Vdc.
Is it as simple as dividing 350 into 5600 which would give me 16 hours of charge with optimal conditions? (This seems too easy.) or am I missing something?
