Review: Okay - So far it works no issues yet will update if I have a problem
Review: Good replacement power supply for WiFi POE adapter - I got this to replace our church's WiFi AP POE adapter's supply, which had failed. This one puts out slightly more current (3A vs 2.5A). It has a 3-prong removable AC power cord, while the prior one was only 2-prong. Overall, it seems better constructed and hopefully will last for years.
