52V Gigabit POE Injector Adapter Power Supply,100/1000Mbps IEEE 802.3af Compliant, for Most Cisco/Polycom/Aastra Phones and More

I bought this so that I could power my Cisco 525 using PoE. My phone is refurbished, and it developed a problem with the power connector. I attached the adapter to my Ethernet port and my phone, then plugged it in. The phone booted without issue. Problem solved.

This 48V POE Injector Adapter Power Supply proved to be a lifesaver for my doorbell camera installation. Since I lacked existing doorbell wiring, this injector provided a convenient solution by delivering both power and an Ethernet connection via a single cable. The setup was straightforward: I plugged the injector into my router and a power source upstairs, then ran the Ethernet cable downstairs to the doorbell. The injector functioned flawlessly, enabling the doorbell camera to operate as expected. I highly recommend it for anyone seeking a reliable and affordable way to power their PoE-compatible devices. 👍

This is the only POE that ive found that will power my extenders. But it also works great for regular cameras.

I have just moved to a new office without ethernet cable ran through the walls, and I needed to power two PoE phones. I ran this, along with a wifi bridge, and it works perfectly. Great product so far, lets hope it stays effective.

You truly do get what you paid for. I have been sent two of these devices (one was a replace for the first one) and both injectors were defective out of the box. I know it wasn’t end user error because I have a known working injector that I hooked up and it worked perfectly. Avoid and save your self the trouble of having to return defective items.

Finally found a low price power injector that works after bad ones from Temu and eBay. Turned on my Reolink camera immediately. I would buy it again.

Perfect for single Power Over Ethernet requirements. Using as a POE injection unit for troubleshooting surveillance equipment at work.
