These handy add-ons are designed to provide backup power to your full-fibre broadband service. This means that even if there’s a power cut, you’ll still be able to access the internet and make emergency calls.

Battery backup units maintain power to the Wi-Fi Hub 2 and Fibre connection box during a power cut, this will enables you to maintain a broadband and telephone service. The battery backup unit will last for one hour, depending on the number of devices requiring Wi-Fi/internet connection.

  • Two backup units
  • Wi-Fi Hub 2
  • Fibre connection box
