Review: Works as described - 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. Review: Made installing my doorbell camera so much easier - 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. 👍 ## Features - Provides remote power to equipment through CAT 5 ,Ethernet cable up to 100 meters (328 ft.). - IEEE802.3af Power over Ethernet with DC 48V 0.5A Power Supply, US Desktop plug type. - Input 110-240VDC 50 / 60HZ Output: 48V-0.5A 24W passive PoE Out put. - Short Circuit, Over Current and Over Voltage Protection. - Compatible with most 10/100Mbps IP camera, IP phone, Wireless IP point and other PoE devices. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08DHWHQT8 | | Best Sellers Rank | #147,728 in Office Products ( See Top 100 in Office Products ) #53 in VoIP Telephone Adapters | | Brand | STEAMEMO | | Color | black | | Compatible Devices | Desktop, Internet Protocol Camera | | Customer Reviews | 4.3 out of 5 stars 288 Reviews | | Data Link Protocol | IEEE 802.3 | | Data Transfer Rate | 100 Megabits Per Second | | Hardware Interface | Ethernet | | Manufacturer | STEAMEMO | | Mfr Part Number | Webcam-HK108 | | Model Number | Webcam-HK108 | | UPC | 779139143628 | ## Product Details - **Brand:** STEAMEMO - **Hardware Interface:** Ethernet - **Color:** black - **Compatible Devices:** Desktop, Internet Protocol Camera - **Data Link Protocol:** IEEE 802.3 - **Data Transfer Rate:** 100 Megabits Per Second - **UPC:** 779139143628 - **Manufacturer:** STEAMEMO ## Images ![52V Gigabit POE Injector Adapter Power Supply,100/1000Mbps IEEE 802.3af Compliant, for Most Cisco/Polycom/Aastra Phones and More - Image 1](https://m.media-amazon.com/images/I/51mX7xXnp9L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as described *by C***3 on December 9, 2025* I bought this so that I could power my Cisco 525 using PoE.
