I'd like to use my ebike battery as a power bank. From some research it sounds like I need a buck converter, particularly of the synchronous variety. I'd be stepping 52v down to 12v to power a variety of devices that don't have huge energy needs (12v fridge, laptops, phones).
I found the product below on amazon which seems to fit what I'm looking for. It's only 12 bucks and reviews (all 50 of them) are generally positive. Sounds like the output voltage is adjusted with a screw ("clockwise big") and then presumably checked with a multimeter.

Has anyone used this by chance, or have a specific product to recommend that would accomplish a similar task?
