Yes, it would still help if the broadband was down. This is not how they work. You said that if there was a power outage it would work, yet when there's a power outage, then your broadband is down too!
These battery backups are constantly attached to the landline phone, albeit it has to be a digital corded phone, not a handset phone with a battery charging base and AA/AAA batteries needed also. The phone then essentially becomes a mobile phone, as such, with a mobile number if the power supply or broadband is down. Because the battery back up is constantly plugged in, then there will be a full charge available if the electricity went off, so you could at least contact someone to come to your aid or emergency services if required.
I'm disabled with very complex needs, so I can't adhere to the government's carer help, albeit that I am entitled to it, so because I don't have a carer, I don't get a care alarm and therefore can't get a battery backup from Sky, yet when I contacted their Accessibility Team, they couldn't tell me what actually WAS available from Sky as I wanted to see if u could change my package that I had just ordered! Virgin Media and BT in NI were able to offer me this backup for free, or for a price if I hadn't have qualified, but their customer service is atrocious in both companies and their deals are too expensive for me to afford after any initial new customer deals, so I decided to go back to Sky and just hope for the best that I never need the battery backup or that someone comes looking for me if there's a power cut or don't contact them in a few days!! 😱
