I would not assume nor try to use any power supply (charger) with max. output of 5V/1.5A or less (5V/1.0A) because those will overheat within relatively short time and probably catch fire ASAP (it might all of a sudden turn into very dangerous game). Please avoid such experiments if not familiar with power supply in usage, rather use compliant docking station in between of … or at least consider usage of at least 3A compliant converter (if about to reduce, from higher value only, power supply provided current for some purpose that is not supported officially): https://www.assmann.com/product-pdf/4016032468707?PL=en.
Again, please recheck twice which power supply connecting toward any smartphone and confirm your expectations with the expert opinion/address (open other relevant review, many very relevant ones present there):
