Any problem using a lower amp charger?

[wrench]

I'm using a Galaxy S4, which comes from the factory with a 2A charger. I'm using a 1A charger, which does fully charge the battery, and unlike a Galaxy S3 charger I tried, this charger does not give a warning about long charge time due to lower amp charger.

So, apart from longer charging time (which I'm ok with because I charge overnight), is there any downside to using a lower amp charger? I'm thinking there might be a slight benefit to a slower charge, but mostly I just want to make sure there's no downside.

Slower charging and might get overheated.

I'm using an app (Galaxy Charging Current Lite) to measure the draw, and the battery is getting 1.1A. Charger feels a little warm, but not unusually so.

I guess from a fire hazard (charger, not battery/phone) perspective, it's better to get a charger that can comfortably handle the current the battery will draw.

There shouldn't be any issue using 1A charger. The only side effect if you're using your phone while charging and you drain your battery faster than you charging it up For example, when I'm driving in my car and have NAV on, screen on, BT paired up, picking up occasional calls, etc. - 1A charger will not be able to keep up with a drain of all the running apps and you really need 2A for that. Other than that, shouldn't be an issue.

Lower amp charging is actually safer for your battery, it will last longer than with quick charger.
