Since the SB-PWR-48V delivers the same standard of PoE - 802.3af, you could still use it to power on the AIR-CAP1620E model. However you are advised to use Cisco AP1600 Local Power Supply (AIR-PWR-B=) which is the officially supported PS for the 1600 series Cisco Aironet 1600 series access points: https://www.cisco.com/c/en/us/products/collateral/wireless/aironet-1600-series/data_sheet_c78-715702.html **Q: Can you confirm if this item has the standard barrel connector, or is it the 4-pin mini-din looking connector? cisco has two hardware revs of wap-581** A: Hello Ryan, Yes, this SB-PWR-48V-NA power supply has 90-degree DC power plug 5.5 x 2.1 x 9.5 mm barrel power plug (https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/small-business-network-accessories/datasheet-c78-740988.html). The one with 4-pin connector suitable for the WAP581 should be this one https://www.amazon.com/UPBRIGHT-Cisco-SG100D-08P-V01-SG100D-08P-NA/dp/B078P921FF Thanks ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good price, great product *by M***Y on August 26, 2019* The product came as described and I'm very happy. --- ## 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/31589615-cisco-sb-pwr-48v-power-adapter-for-small-business-limited](https://www.desertcart.us/products/31589615-cisco-sb-pwr-48v-power-adapter-for-small-business-limited) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
