How do you keep your nuc running during a power cut? Mine is a 12v unit drawing 10w. I got a small battery backup unit for it that keeps it going about 15 minutes which is fine to handle the transient outages we frequently get but I need something that will keep it running through a longer break ie up to 2 hours. I already have a 12v 7Ah battery and a car charger that is unused, can i repurpose these somehow?
