I'm looking at getting a level 2 charger. Will all level 2 chargers work? Looking at buying used online. So I want to make sure it is compatible. I can always try it out.
they should all work now, but if you're buying used, don't buy too used, they have a limited lifetime.
I got a broken one from eBay, which was refunded by eBay because it was through eBay motors. I don't know what to do with the broken one as I never got any sort of return instructions. Other than that, I got another one and it works fine. A lot of them seem to have a bunch of features. If you're satisfied with the car's charge scheduling, you don't need the advanced features in the charger. I'm happy with the car's charge scheduling, so I saved my money there and got a new one. If the charger has the features you want, it's best to delete all the items in the charge schedule so the car doesn't interfere with the charger's scheduling.
I purchased a Schumacher SC1455 Level II (recommended on PriusChat, thanks) from Amazon for $230 a year ago. I use it almost every day and sometimes multiple times a day based on how much local driving I do. There's value in purchasing things new and with a warranty that guarantees that it works.
