Using Official Raspberry Pi Power Supply to charge phone?

Question

— E J | Sources

Answer

USB standards specify 5V plus / minus 0.25 V which is supplied by pi 10W supply whereas 13 W supply is 5.1 V which is not recommended



So you can use the 10W power supply



Thanks to Ghanima in comments
, who pointed out something I overlooked




The 13W supply is listed as 5.1 V with a 2% line regulation (that would be 5.1 V plus/minus 0.1 V) which puts it well within the USB spec




So you can use both chargers safely, as pointed out in other answer giving additional reasons. Sorry for missing this detail
