Beginners • need help in powering raspberry pi zero 2w

im using pi 02 from last year

due to occasionally freezing i upgraded my setup and i use raspberry pi 27 watt charger to power up raspberry pi usb hub which gives power to ssd and seperate power for raspberry pi 02w, running smooth ,but this makes things messy

i want to use single power source which power pi 02w and also powers my ssd directly from pi

options came in my mind

1. use official raspberry pi 3 power supply (5v 2.5a )
2. use official raspberry pi 4 power supply ( 5v ,3a )


1 one use micro usb ,so it can directly goes into pi 02w
2 one use usb c , so i need adaptor to change it to micro usb

pi 4 power supply is 3$ cheaper and have extra power

i want to use pi 4 power supply but i read somewhere that their is some compability issue ( releated to e mark cable ) hence im fearing that if it doest give enough power to pi 02w ( due to some compability) ,then it will go waste

i have seen some people where pi 4 power supply only providing 300-400 ma to mobile where its capable of providing 3a ,no issue with pi4


please help
