I am trying to get as many devices to run off the POE switch as I can, that way I only need to have the POE switch and my main server plugged into the UPS so when the power goes out, they all remain on from that single switch powering them. I had a hard time finding a splitter that could provide enough power to my 5G modem which requires 15v at 3.0A. This adapter seemed like the only splitter out there that can do both the 15v and the required amps, unlike many other adapters I've tried. I took a chance and was pleased to see it worked perfectly. So now I've managed to get my other 2.5gbe network switch, my router (both using different adapters) and now my 5G modem.The only thing left I would like to power with it is a micro PC I use for media playback and watching my blu-ray rips that are shared on my file server. That PC needs 19V at 3.42A and sadly this adapter just does not provide enough power to do it which I figured would be the case. The computer would power on, but within seconds it shuts off. It's the closest I've gotten for it so far. At least its working great for my 5G modem which also requires a bit of power to run, but its handling it.I am looking to upgrade to a better POE switch that can put out more power per port. I suspect that may be another bottleneck of mine. Hopefully I can find some other option for the PC, but its not critical really, the modem was more important, and I'm glad to see its working great!

I bought this so that I could power my T-Mobile 5G Home Internet Router (G4AR / G4SE) which I have placed in my attic, far from any 120v outlet. I have it connected via a 35ft Ethernet run to my equipment rack with a Ubiquiti Unifi US-8-150W PoE+ Switch. Note that despite not being PoE++, the adapter is able to pull enough power from my PoE+ switch to operate the router and a usb-c fan I have plugged into the router itself.It is fairly pricey, but that is likely due to it being in-spec with both PoE++ AND USB-C PD. Other, cheaper adapters may only supply limited voltages like 5v, and may not even be regulated. At best those cheap adapters won't power your device, at worst they will damage it. In my case, the G4AR requires 15V over USB-C which this adapter easily provides.Highly recommended.

This device arrived and I was excited.I tested it on my PoE switch in multiple ports with PoE enabled.It works, but the power light is pulsating, and the deviceplugged into it is actively turning on and off with charge stateat the same pace as the adapter.my switch notes the power going through, but also notes something iswrong and gives an error.For this reason, I cannot recommend this product.Maybe I got a dud.

I bought this adapter because it said it is compatible with IEEE802.3(af)(at)(bt) [POE, POE+, POE++] and conforms to the USB-C power delivery specification for 5-9-12-15-20V @3A or 45W whichever limit is reached first. So far, so good.My application connects to a Zyxel GS1900-EP IEEE802.3at POE+ (30W max) port to a Microsoft Surface book 2 laptop for charging and 1Gigabit wired Ethernet through a USB⇉Ethernet adapter. I definitely get gigabit speed over Ethernet. Power delivery to the laptop overloads the splitter PS60UC / GS1900-EP power delivery combination. The PS60U reacts badly to this overload condition by attempting to renegotiate at 1-sec cycle times. This causes the laptop to be unusable and doesn't charge the battery or power the laptop. What I expect to happen is for the PS60UC to detect the POE+ port and limit power to 30W by negotiating USB-C down to the upstream POE limits. This should allow the laptop to run and provide lower charge rate to the battery.I measured the laptop power through a wall 130W USB-C charger and see once the battery reaches full charge, the laptop only draws 15W-20W to run. This suggests 10W should be available from the POE+ port to charge the battery. On the higher powered adapter, the laptop can draw up to 53W while charging. I expect the laptop will still charge and operate properly if the USB-C negotiates a lower power level to stay within 30W, or the PS60UC 45W limit. The PS60UC doesn't behave this way.I ordered a Netgear IEE802.3bt POE++ switch (60W/port) to see if this will put enough distance from this operating condition to resolve this problem. In about another week I'll be able to determine if I keep the two PS60UC units I bought (work & home) or send them back to try some other solution. If this unit were able to negotiate a lower 30W power level to stay connected and stable on POE+ IEEE802.3(at) power source while powering a laptop that wants to negotiate for more, I'd give it 5 stars.

Using it to power a 5g home Access Point. No issues

Based on the reviews, I tried to use this with my T-mobile 5G internet modem TMO-G4SE. All it did was pulsate. I measured the stock adapter and it is 15v (14.6) at .6 amps and 8 watts when connected. When I tried with this adapter is just flickers 14.1v or 14.6v and then restarts. I tried a 60 watt PoE++ Ubiquiti injector, and a Trendnet PoE 15.4 injector both with the same results on a 15v load. It did work to charge a USB charger at 12v (11.9) at 10 watts, but failed with the higher voltage required to start the 5G modem. Disappointed, not sure if I will try a replacement or look at another vendor.

I use this to power a T-Mobile home internet gateway (Sagemcom Fast 5688w) with no issues over PoE. That device only draws 10-15 watts, but requires a PoE++port which is a bit odd, but I'm assuming it's a quirk in the gateway and not this splitter.I mounted to the back of the bookshelf and with a short path cable and USB-C cable, I'm able to run the gateway with a battery backup with a single cable ran to it.
