I called the Service Call Center and they said that "FL" means the battery is fully charged, which is the way it is shipped from the manufacturer.

Since you say, it is a 12v DC portable Jump starter, the battery inside it is also a 12V battery. You need a 12V charger (eliminator, wall adaptor or whatever you may call it) Regarding current, it could be anything above 500 mA. Better if it is a 1A or 2A or even 3 A depending on the amount you are willing to spend. Now is the most important part. The polarity. I do not know it since i do not have this equipment. Most chances are that you will find (on the RoadPro) a circle and a dot (along with a +VE and -VE marked near it) around where you plug in the adaptor. For most equipments the outer circle is the -ve and the inner dot is the +ve. (unfortunately this could be reversed in some equipments) If you can find this notation on your RoadPro you are lucky. Just go to any electronic shop and buy an adaptor (12V) that matches this circle and dot notation. The same symbol representing polarity will be marked on the adaptor also. Else, you will need the assistance of someone who can check the continuity using a multimeter. This way you can find the polarity. It is pretty easy. Hope this helps.

It will not charge without an adapter suitable for the rated charging amperage. Also,
it must have a ground.

I had the same problem today and I found out that is the battery itself causing the problem. It's actually the connection. So disconnect the battery and scratch the battery pins and connect them again. If you can dip them in soda water (no sugar in it!) that would be better.
This problem starts as the battery beggins to get old and combined with cold weather outside becaomes a receipe for disaster. Anyway, if you can't afford a new battery at the moment remove your battery from your car (but first try and drain it totally...leave a light on or something) and recharge it (fully) with the duralast (havbe the duralst plugget into a outlet). It will have your battery working for couple of weeks.
