@rbaker said in Is 2.4A enough?:
@HenrikoMagnifico I have a brick similar to what you describe but I have 4 usb ports on it. It is rated at 4.5A. This means that inside my cabinet, I can power the pi comfortably with joypads, keyboard and an ipac decoder. I also have another for charging things like phones and kindles at the same time. As long as your current draw across all devices doesn't exceed the rating of the charging device, you will be fine. No need to worry about how the current is shared. Your devices will only draw a maximum as described on their case. E.g. This keyboard I'm on is 70mA, so only 0.07A out of the 4.5A available. Look on the back of devices, usually printed on. A charger can never output more than a device needs so don't worry.
Thanks for the help, I will purchase the USB charger I talked about earlier :)
