Why?** A: This is a poe injector - it adds power to any non-PoE switch. In the description it says * this is not a switch - you use it to add PoE to any switch or router for each PoE port used, you need a jumper to a non-PoE switch. **Q: can this device power 4 class3 devices at the same time? If not can the power supply be swapped out to one that can support?** A: This injector kit cannot support four, class 3 PoE devices at the same time. This injector, WT-GPOE-4, can be used with other power supply options such as the PS-48v60w, or PS-48v120w if you need a higher power budget. For further questions, please contact our technical support team. **Q: Can i use this to power 4 ubiquiti uap-ac-lr wifi access points?** A: If they have a date code of 1638 or higher, yes. Models with that date code (or higher) will operate using 802.3af PoE. Models with earlier date codes will need 24V PoE. Please feel free to contact our technical support team for more information. Thank you! **Q: Does the power supply come with this product? I dont see that mentioned in the description or in any of the poctures.** A: It says in the title and description - No power supply included * We recommend our 48 volts DC, 1 amp, 48 watts Power Supply * 2.1mm x 5.5mm DC power jack ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Mode A passive injector *by S***N on August 11, 2020* I originally purchased this injector with the PoE Texas PS-48v60w power supply.This combination works well with my Netgear devices that function as 802.3at passive devices.It does *not* work with my Reolinks, which are 802.3af active devices.When I wanted to use this injector to power a Unbiquiti Nanoswitch with Mikrotiks connected, I purchased the PoE Texas PS-24v60w power supply. This combination did not work, and I contacted PoE Texas for advice.Maria got back to me quickly with a detailed response that got me on track. The Ubiquiti switch uses a different wiring scheme (Mode B) that is not supported by the GPOE-4A. She pointed to the GPOE-4B injector as the correct injector to use for that application.As far as I can tell, this is a good product with great support. I suspect that the negative reviews are from people like myself, who are unfamiliar with the different PoE standards and are using the wrong product. ### ⭐ Who's got the Power? Not this one. *by J***O on April 19, 2025* I would like to say its good, but it doesn't come with a power supply. ### ⭐⭐⭐⭐ Nice home network POE injection with GIGABIT speed. *by N***2 on January 31, 2025* A very nice inexpensive way to deploy POE equipment with gigabit speeds. I’m using this device in a home network and it’s working great. Only downside is it doesn’t have a LAN port to give it more versatility. ## Frequently Bought Together - PoE Texas 4 Port PoE Injector - Gigabit Passive Power Over Ethernet - 802.3af or at Compatible PoE Injector for VoiP Phones, WiFi Access Points, IP Cameras - 4 Ports of Data + Power Out - PoE Texas 48v Power Supply - 48 Volt 60 Watt AC to DC Power Supply for Power Over Ethernet, PoE Injector, Adapter, Splitter, Extender, Network Switch - 60w 48vDC PoE Power for 802.3af, 802.3at Devices --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/18740205-poe-texas-4-port-poe-injector-gigabit-passive-power-over](https://www.desertcart.vn/products/18740205-poe-texas-4-port-poe-injector-gigabit-passive-power-over) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-17*
