Hey, I was looking to a UPC to power a preamp with a 9v 1 amp power supply for maybe 3 hours, 6 hours if possible. What would be a good UPC for a thing like this? Thank you.

We typically measure UPS load in watts, but estimating roughly 100w draw or less from that device, an SUA1500 will give you 2h 52 minutes of runtime at 100w. You will get more runtime if the draw is less than 100w.
