New RV USB plugs, what amperage are they?
Many new(ish) devices require the higher powered, 2.1-amp USB plugs. On the flip side, most of the plugs I've seen in RVs I believe are under an amp. Anybody knowledgeable on this subject? Is the R...

No one can really answer your question, you will have to try a test charge to find out unless they have marked the ports as to what they are.
USB1/2 ports specifications by PC standards are limited to .250A and USB chargers typically will be .5A-2.4A with newer "C" ports at 3A.
Most of the USB chargers that are unmarked will be 1A or less, 2A ones many times are marked. Two port chargers often "share" current and unless marked that current is divided between both ports. Some of those may deliver full current only when 1 port is used.
If not marked, assume 1A or less per port until you do a test to see how fast your device charges. If it charges too slow then consider using another USB charger.
