I bought a few cheapo UPS units one time. They're only 2-prong (no ground) and the capacity is low. But they were like $20 each with "refurbished" batteries from the vendor. All of my routers are 2-prong so I have one unit for every router/switch/AP in my house. Actually really helpful and if I was running a Chromebook for a server like this, I could keep my services accessible remotely even if a short power outage happened!
