## Questions & Answers

**Q: You listed the input three separate times, but what is the output?**
A: Its a passive plug.  The power supplied on the input will be provided on the output (IE if you need 12V to drive a remote device, you need to supply 12V)

**Q: Is this a 5.5mm or 5mm plug? The listing mentions both but thats not compatible.**
A: Power Jack: 2.1x5mm male. 
Power Plug: DC 2.1X5.5mm female
As the plug is slightly wider so the 5mm jack can insert properly.

**Q: Has anyone gotten true “gig” speeds over this? Have you see 900+Meg on throughput?**
A: yes this injector/splitter definitely connects all 4 pair and I have tested it at 1000Mb/s.  It works great and it is the only injector/splitter that i have found that works at 1Gb/s speeds

**Q: What’s the max amperage/wattage?**
A: 10A For standard gauge Ethernet cable

## Customer Reviews

### ⭐⭐⭐⭐⭐ Yes, a passive 1gbit poe adapter that works!
*by T***P on January 13, 2020*

I am by no means an expert on this but from what I can tell these are quite rare. Not a lot of companies make passive poe adapters that are both passive AND 1Gbit.We have a fiber to ether box provided by our ISP on the roof of our home. They used a 100mbit passive adapter. It was starting to fail so I had to replace it, decided to see if I can find a passive 1gbit one. I did.After replacing the old one with this, the ethernet port auto negotiates to 1gbit. My internet speed jumped from about 95mbit to about 270mbit.There is about 3 floors between my home router downstairs and the fiber to ether box on the roof. And I am powering it via a good quality 12V (5A, shared with my router and switch though) adapter. 12 hours so far, no issues to report!

### ⭐⭐⭐⭐ Works a lot better than I thought (Still working Febuary 22, 2024)
*by U***1 on November 4, 2022*

I decided to use this to bring battery power from my backup battery upstairs to my WiFi. Around a 35-foot run with minimal voltage drop (<0.2v) despite multiple cable extensions+changes in cable gauge.It didn't work directly with my WiFi since the voltage regulators inside my access point can't handle the voltage changes when the battery dips below 12.2V, but a Netgear 16-port switch holds up a lot better.If I used a boost-buck converter I think this would work perfectly with my WiFi 24/7.Update: November 4, 2022 -> Febuary 22, 2024. This is still working. I used a voltmeter to adjust my boost-buck converter so that the voltage would account for the drop across the ethernet cable. It works perfectly. I drained my LiFePO4 12v battery all the way down to 11.0V before my solar controller decided to cut the voltage output. That's when I realized I was using PoE and forgot to finish the battery system maintenance.Probably going to buy another one of these soon. I have another project that needs better PoE and this is about the best injector+splitter kit I've seen on Amazon so far, and I've been looking.

### ⭐⭐⭐⭐⭐ Works great with Netgear Orbi
*by M***Y on June 30, 2022*

After some trouble with various other PoE setups, I decided to give this a try to power my Orbi using an ethernet cable. To my surprise, this works great. I plugged my included power adapter into one end and used the included splitter on the end end. Worked flawlessly - great for setups where there aren't outlets available or are practical.
