That's a separate question. Yes, reliability is always something to consider when going non-OEM, but the question was about amperage ratings only. For example, my answer is correct even when applied to an OEM charger of higher or lower amperage than what came with the device.
One thing I did forget to mention about lower amperage chargers is that you'll be putting more strain on the components due to running flat out more than the included charger. That can cause premature failure in the charger. There is a risk of it damaging the device being charged as well, but it's been my experience that the charging brick will show signs of failing before getting to the point of danger to the device. I.e. Slower charging than spec or getting extra warm during charging. So the risk is small, and avoidable if you are paying attention. Under normal conditions, there is no risk. I don't recommend using a drastically undersized charger in general, though, and not just for that reason. The big reason is simply time waste. There isn't much of a cost difference to go with better chargers, so may as well do that if you are shopping anyway.
