My country has a problem with the mains electricity supply, which cuts off and comes back straight away. My router restarts every time that happens.
What I like to know is: What would be the most efficient way to have a 5 seconds power supply backup on my router?
- Router: ASUS RT-N12+
- Power Supply:
- AC Input: 110V~240V (50~60Hz)
- DC Output: 12 V with max. 0.5 A current
A schematic would be amazing since I am totally new to this subject.
