Constant Vigil MK2 with integrated battery. No longer being manufactured. IYKYK.

Very handy device. Like a mini UPS with enough juice to run your networking essentials like the ONT and router. So when the power goes out your internet keeps going.

This one is a few years old now and I can't speak for the battery health but it has got us through a number of power cuts.

Comes with the pictured cables. I only used the red to black ones which worked on my router and ONT.

$75 plus shipping

I’ve got two of these (but not intergrated battery).

stopped using one because I was too lazy to replace the battery. The other one, I stopped using because I was too lazy to get a new connector (as router changed from the original).

shame these guys don’t trade anymore…I feel they didn’t market themselves properly, otherwise it was a good product.

im wondering if I just go get some adapters and a new battery or two !

Yes, they are a really good unit! Should have been more popular with rural and semi-rural folks. Especially after weather events when you are often without power and mobile service. There's a bit of discussion about them here.
