Since the POE ma ximum power output of 802.3af's is only 15 watts.when used on the IEEE802.3af standard POE switch/POE injector, the power of the connected device should be kept within 13 watts (such as 5V2.5A/9V1.3A/12V1A), exceeding this power will cause the POE switch to start Overload protection.
