current and voltage are two different things.
voltages = volts. current = amps.
an ipad charger would be 5V and is the appropriate voltage.
pretty much all devices are really sensitive to higher voltages
than they are designed // rated to run at.
over voltage is one of the easiest ways to kill an electronic device.
any device only draws as much current as it needs.
doesn’t matter if your power supply can supply half an amp (0.5 amps) or 1000 amps
if it only needs 0.1A to run it will only draw 0.1A from the power supply.
if u use a power supply that is rated less than or equal to the amount of current your device desires
then u actually run the risk of overworking your power supply, which may then overheat, damaging the power supply, damaging your device, maybe even starting a fire.
a higher current supply is actually safer because it will be able to do the same job more efficiently with less stress on its components. less stress = less heat = less chance of danger.
i know ur intentions are good but spreading misinformation and half truths on topics that u may not fully understand doens’t really help anyone.
