I use an Instant Pot now, but I've had electric pressure cookers since the mid 1990s. I typically refer to a bean cooking chart in Lorna Sass's book, Great Vegetarian Cooking Under Pressure. Electric pressure cookers don't have as high pressure as stovetop, but the times work out well regardless. I never soak my beans (I have, but it's not needed, and pressure cooking reduces anti nutrients better than soaking), and I always do natural pressure release. Unsoaked pinto beans need 20 minutes high pressure, black beans need 22. For reference, I'm at about 1400 foot elevation.
My husband grew up eating beans made from dried beans, so he's never much cared for canned beans. I do think canned beans can be economical, and I have them in the pantry now because of Covid. I think I pay 44¢ per can for Aldi canned beans. Canned beans are probably one of the cheapest, healthiest convince foods out there.
