TP-Link 2.5G PoE+ Injector (TL-PoE260S) - 2 2.5G Ports, IEEE802.3af/at, Supplies up to 30 W, Integrated Power Supply, Plug & Play, Desktop/Wall-Mount

Powered my access points for a couple years until I got PoE. Always came back online after a power outage.

Meets all stated specs, stays cool. No problems so far.

I bought this network extender to connect a web camera that I wanted to locate on a power pole 40 meters from my house. Once I worked which phase wire to connect to, so both were n the same phase, it connected easily and has been working without problem for a couple of months now.

Works great for extended range of my webcams

I have two Unifi Flex switches. These are quarky little entries in the Unifi lineup as they are are 5 port gigabit switches that do have 4 POE ports but no internal power. The power for the switch and for any downstream POE devices is supplied by an upstream switch or POE injector. They do support (and recommend) 802.3bt 60W as the the power supply. These TP-links work well for that use. I have two switches and two injectors. The first is powering an access point and a PTZ camera. The second is powering three stationary cameras. You may notice the POE availability listed as 46W. This is a self imposed limit inside of the switch as the remaining 14W is to ensure the switch isn't starved of power by overrunning the injector. The injectors are in a garage and have shown no issues in six months. They run cool and haven't shown issues about the lack of temperature control. I would buy again.
