DC Barrel Plug

5.5mm X 2.1mm is often referred to "standard DC barrel connector" or plug and is the most common size of power jack for electrical adapters for WiFi equipment, including our Power Over Ethernet injectors.

Boats and RV's are generally 12v and they do not want to run their 110/220v inverters all the time. With our ADEBARREL4 you can wire directly into the boats power supply. You may use it with our POE injectors for examples: APOE03, APOE01 & APOE02-WM) by joining a female 5.5mm X 2.1mm power jack, then attaching a male jack connected to the 12v boat system. The male jack will also connect to the POE injector.
