there is power lost in between the output side of charger and converter side behind phone

thesun
sorry i quote wrongly, that one is for wireless charger. power loss when convert the "wireless" to battery power

usually it is device who withdraw amp (tarik), instead of charger push out amp.
so safe to use high amp charger, at cost of more expensive price.

if underpower, it will drop voltage to cover back the amp that withdraw by device.
so either it take long time or wont charge at all, depends got safety implementation or not

traditional charger get hot is normal for heavvy type (built in transformer).
nowadays phone charger design very light & small, inside is frequency switching PCB.
wont generate a lot of heat unless short jor

btw, not sure about shorting 2 wire in middle will work for all type because they are data in & data out pin for computer
i no plan to try at all (own risk)
