Gigabit USB Type C Active PoE Splitter 48V to 5V IEEE802.3af Power Over Ethernet for Raspberry Pi 4B

As someone who's been tinkering with Raspberry Pi projects for a while, I was looking for a way to power my Pi 4 without the usual mess of cables and power adapters. This PoE splitter from DSLRKIT has been a game-changer. Pros: Reliable Power Delivery: Provides a stable 5V 2.4A output, ensuring my Raspberry Pi 4 runs smoothly without any power issues. Gigabit Ethernet Support: The splitter supports gigabit speeds, making it perfect for projects that require high-speed connectivity. Compact Design: Its small size makes it easy to integrate into tight spaces without adding bulk. Easy Setup: Simply connect the PoE input from your switch or injector, and you're good to go. Cons: Compatibility: Some users have reported that the green LED on the Ethernet port doesn't light up, which could be confusing. However, this doesn't affect the functionality of the device and hasn't affected me personally. Final Thoughts: If you're looking to streamline your Raspberry Pi setup and eliminate the need for separate power cables, this PoE splitter is an excellent choice. It's affordable, reliable, and does exactly what it promises. Highly recommended!

I used this with a "MotionBlinds smart hub" The supplier claims it doesn't support PoE but I was skeptical of that as USB C power isn't typically something that's particularly energy intensive The USB hub from them doesn't have an ethernet port but that's neither here nor there, as you can still use this splitter to provide power only. If you had a device that had an ethernet port, then you could use it for data as well. I just needed power, in order to free up a power socket. It's pretty decent in that sense I'd recommend this for sure.

After seeing the reviews that say this device doesn't deliver gigabit performance I decided to test the effect on network throughput. I used the iperf3 program to do this, running the server on a desktop PC and the client on a laptop that was first connected directly to the POE switch, and then connected via this device with the power from this device also plugged into the laptop. The results were that my network setup without this device achieved about 940Mbps throughput, but via this device that dropped to around 850Mbps. So it seems that this device DOES slightly reduce the network speed, but only by around 10%, which I don't think is a major problem. As for the power side of things, I found that devices that expect to negotiate voltage and current, such as a modern iPad and iPhone, would only draw 5V 0.5A, which is the original USB 2 spec. Equipment that requires more than 0.5A and simply draws what it needs did seem to be able to draw 2A. So it seems that to make the most of this device you need to connect equipment that DOESN'T negotiate its power draw using the PD protocol. Possibly this also explains why another reviewer saw this adapter overheat and fail - if connected equipment tries to draw more than the specified maximum 2.4A there might be no protection. So be careful not to connect anything that requires 2.5A or more. Like other reviewers I also found that there's no status light for network activity, only for power, but for me this isn't a big issue. For my use case I'm completely happy with the way it works. Hopefully my research will help others assess whether it will do what they need to do.

Whilst the local link is 1Gbps, the throughput is actually limited to 100Mbps

I have used this to power my Pi 4 Model B from a POE ethernet port. This allows me to power the device without running any other wires and also I am able to power cycle the Pi via the switch software so it saves me having to use ac psu and a smart plug. Which means a mear £10 is basically a saving.

Works great for my raspberry pi 4b. Combined with pxe boot (and a poe switch) this is all you need to have a working raspberry pi server, saving money on cables and power supplies.

Wanted to be able to use google WIFI using PoE as the "puck" is mounted on the ceiling in one room so getting power to it any other way was going to be difficult, Worked perfectly first time and is happily supplying power and gigabit network

Worked perfectly with my Pi 4 and pulling 4.10 W down from the POE switch. Quality seems good, only thing would be a slightly longer cable run would have suited me better.

I use this with my Philips Hue hubs and it works perfectly. So good to get rid of a bunch of power cables and free up some slots. Have been using them for just on one year now with no problems at all.

Geniale Lösung um USB-Geräte POE fitt zu machen.

Alimenté correctement un pi4 8GB avec son SSD M2 branché sur un port usb3 du raspberry. Donc rien à signaler si ce n'est que le poe est assez chaud. Mais rien d'anormal ... Quand on abaisse de 48 ou même 57V à 5V en tirant 2A .. pas de mystère : ça chauffe obligatoirement un peu

I bought 3 of these adapters and they all work, and work the same way. They do what I need, 5V @ >1A. Pro: — Runs Raspberry Pi 4 @5W, required for boot-up and heavy processing (all 4-cores @100%) — Works with Raspberry Pi 4 Pre-v1.2 USB-C connectors (CC lines wired together, not separate as required, newer RP4's do it right) — Convenient small size, light weight — Will charge my cell phone using a µ-USB adapter — Provides the higher current needed to run the RP4 reliably. My laptop Type-A USB ports don't provide enough power, and my pre-v1.2 RP4 won't power off the USB-C port, because it is wired incorrectly. This makes this higher power adapter necessary for my application(s). Con: — USB-C is 5V only, won't negotiate to higher voltages. — No real con, except the green light on the Ethernet port never lights. I couldn't decide if this is an Ethernet activity light, or a USB-C connected light. Either way, nothing I do makes this light turn on. Wondering what it's for?

Sto realizzando un piccolo sistema di videosorveglianza per una seconda casa. Per fare sia da router che da server per le telecamere ho comprato un Raspberry Pi 4 da 2GB (qualsiasi altra versione sarebbe stata adatta allo scopo ma quella era la più economica). Avendo già tutte le telecamere alimentate da uno switch PoE e mi sono detto "tanto vale alimentare anche il Raspberry Pi così e avere solo un cavo di alimentazione che va allo Switch". Sapevo però che i vari HAT PoE fanno aumentare di più di qualche grado la temperatura della scheda e che il Raspberry pi 4 già di per sé non è freschissimo, così ho deciso di optare per questa soluzione esterna. Per ora posso dire che funziona senza problemi e sembra ben costruito. Speriamo nella durata. Aggiornamento: Funziona da mesi ininterrottamente senza problemi.
