The power injector provides up to 15.4 W over the unused wire pairs of a Category 5 or better Ethernet cable, supplying enough power for a distance of 328 ft. (100 m) on the Cisco Access Point. It is a general output for all APs. **Q: Am i missing something or should this be powering my cbw140ac-b? my wap turns on, green for 3-4 minutes then off.** A: You don’t need this particular unit. So long as your PoE source supports 802.3af, and the source is not over the limit. I use a switch to power my 240Aac wap’s. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Deal *by J***Y on 13 October 2025* ### ⭐⭐⭐⭐⭐ Works as expected not issues with random shut downs. *by R***2 on 29 July 2021* ### ⭐⭐⭐⭐⭐ A very helpful device *by D***K on 26 June 2021* ## Frequently Bought Together - Cisco Business Power Over Ethernet Injector | Limited Lifetime Protection (CB-PWRINJ-NA) - Cisco Business 140AC Wi-Fi Access Point | 802.11ac | 2x2 | 1 GbE Port | Ceiling Mount | Limited Lifetime Protection (CBW140AC-B) - Meraki Go Ethernet Router Firewall Plus | Cloud Managed | VPN | Cisco [GX50HW-US] --- ## 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.us/products/287282920-cisco-business-power-over-ethernet-injector-limited-lifetime-protection-cb](https://www.desertcart.us/products/287282920-cisco-business-power-over-ethernet-injector-limited-lifetime-protection-cb) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
