你有冇睇官網段嘢?
To accompany Zero 2 W, we’re also launching a new official USB power supply. This closely resembles the Raspberry Pi 4 PSU, but with a USB micro-B connector in place of the USB-C connector, and with a slightly reduced peak current rating of 2.5A. Even this is overkill if you’re powering a Zero 2 W, but it comes in handy if you want to power a Raspberry Pi 3B or 3B+.
都寫到明 "overkill"....再講,如果無咩特別嘢駁(例如 USB HDD/keyboard/mouse/HDMI),做我頭先講嘅 headless operations(事實上用 Zero 系列嘅就多數都係咁玩,或者會駁 GPIO 但呢 d 都唔使用電),有人測試埋 overclock 之後都用唔到 1A 電,咁現有嘅電腦 USB port 都俾到電啦 |
