Fritzbox's power consumption

[binary_dreamer]

Hi. i am running Fritz 7270 and 7170 in two different sites. i would like to know its power consumptions so i could get a battery or a UPS to get them alive for more than 12 hours.
In both places they do get power cuts quite often for more than 8 hours.
i would appreciate a cheap solution.
sincerely yours!

The average power consumption of the two boxes is about 6 to 8 Watt at 12 V DC (0,5 to 0,8 Ah)
The cheapest solution would be an automotive lead battery or a smaller one from a motocycle.
The charging unit should be designed for continious/refresh charge and could be a little bit more expensive.

thanks a lot for the quick reply.
6 to 8 watt for each one right?
any ideas where to find a diagram how to build the charging unit?
