devices lose their static ip after the router reboots

I set static IPs on my NAS and printer, but after a power cut some of them came back on different addresses and the printer vanished from every laptop. Should I set the IP on the device or reserve it on the router instead? Bit confused about the difference.

Set the reservation on the router instead of a static address on each device. In the router's DHCP settings there's usually a 'reserved IP' or 'address reservation' list, you tie the device's MAC address to an IP and it gets the same one every time, reboot or not. If it's phones losing them: they use a random private MAC per network, so turn that off for your home Wi-Fi or the reservation won't stick.
