1 in 2 Out Gigabit PoE Extender, NICGIGA 2 Port PoE Repeater 100 Meters(328 ft),IEEE 802.3af/at Power Over Ethernet PoE Splitter to 2 PoE Devices Like IP Cameras, IP Phone, Wireless AP

Works as advertisedThere is a deceptive ON/OFF switch on the front, you will want it OFF in most cases. It's for port isolation, ON disables data traffic to/from the POE-in port

The small 3 Gigabit power over ethernet port switch by Nicgiga is made in PRC (china). I tested this small POE switch at the end of a 70 meter CAT6 run, and I was able to get full gigabit speed negotiated at both ends. I use the normal mode since I do not need the VLAN separation. The 250 meter mode limits the negotiated speed to 100Mbps. I was able to get 18 watts out of port one and daisy chain another POE switch for another 33 meter run (with gigabit speed negotiated end-to-end). I am not familiar with the Nicgiga brand, so I am not able to talk about durability. The description mentions 4kv lightning protection, and I do use this on an outdoor run, so I am curious to see how hardy this little switch will be.4 stars

These are great for support issues to provide a solution on PoE devices.

I was splitting a rj45 connection but one extender would not work. Using this it works great b

Wish I found sooner!

I am using this to power my Omada EAP-225 Wireless Access Point and is working wonderfully. I have been using it for about a day and it seems to hold up the wireless signal and I am able to connect to my Wireless Access Point without any issues. Speed is not affected and Signal Strength has remained the same when using this device.This does not come with a separate power supply, instead, it will be connected to a PoE switch using its PoE-IN port, and there is an on/off switch. I like the On/Off swich as it gives me a quick way to power-reset devices connected to it.I wish this device has UL or IEC or ETL certifications, but other than that, device works as you'd expect!

Bought this in February. Doesn't work well anymore. Cuts in and out or just stops completely. Wish it would have lasted longer than 5 months.

Plugged this into a Ubiquiti switch & a Cisco switch (separately of course) for testing purposes.On the plus side, it worked flawlessly on both Ubiquiti and Cisco with zero issues when staying within design parameters (be aware of what you want to plug in to this). It is, of course, only 1GB uplink for all devices, but if only one is pulling real bandwidth, or if all three are 'lightweight' devices for bandwidth, it works like a charm. I was able to pull almost full line speed (gigabit) from 'one' device so long as the others were not also trying to pull (or push) full bandwidth. If all three tried, it balanced it decently with some limited overhead. 'Streaming' caused no issues on three devices even at 4k.In both cases, it was able to power two separate Raspberry Pi 4's with PoE Hats and a simple camera with ease, which was my design intent in getting it.Be Aware of your Power Limits! This is not a flaw of the device, it is an inherent limitation in "splitting" PoE: it can only pull 30W from the switch it is plugged in to, takes 4.6W to operate, leaving a budget of 25.4W of power to distribute accordinglyAs a demonstration of this, changing the 'basic' camera out for either a full fledged WiFi 6 AP or a Pan-Tilt-Zoom camera meant that one of the three went either unpowered or underpowered; with the AP it just wouldn't boot (an older WiFi 5 AP from a different brand managed just fine). When the PTZ Camera was plugged in, all three worked until the light kicked on or the camera was attempted to pan and the camera would reboot. In both cases, this makes sense as both the WiFi 6 AP and the PTZ Camera want between 28 and 30 watts of power max on their own, where the RPi's generally pull between 2-5 watts on average. Added together, this makes sense with the 25.4 watt limit across the three devices, when "idling" things were OK but would cause issues when power draw exceeded power limits.
