Hi
I am bit confused about the Wattage rating of Qi (wireless chargers)
e.g., they come in different flavours as 1W / 5W/ 7.5W / 10W etc
I know P = V x I
But, I am struggling to understand how the above Wattage translates into Voltage & current
e.g., I were to charge a Li-ION battery 4.2V, what is the maximum current that I could get out of the above?
& what happens if battery voltage is different e.g., 4.22V or something like 3.7V (during charging)
& if my receiver demands more current than what Charger is able to supply then would it damage anything?
