I have a couple, keep them in the cars, they’ve always worked fine. Random brands bought off Amazon, didn’t buy the cheapest or the priciest. One looked like a Norco, different brand, same actual maker I suspect. You do want to check them occasionally to make sure they’re still fully charged. I don’t know of one that can be left connected to the car (to stay fully charged), but that would be a good feature to have.
