In addition to protecting your devices from power outages, a UPS also provides protection against power surges, which can occur when the voltage of the electrical supply spikes above the normal level. 

For a WiFi router, a UPS is particularly important because it allows you to maintain internet connectivity during a power outage, which is critical if you rely on the internet for work or communication.

For a laptop, a UPS provides protection for your data and ensures that your device does not suffer from sudden power loss, which can cause data corruption and system crashes.

Overall, investing in a UPS for your WiFi router and laptop is a wise decision that can help you avoid data loss, prevent damage to your devices, and maintain connectivity during power outages.
