13$ Aliexpress RTL8812AU module, is it suitable?

Hey guys !
Along the TaoBao modules, I found this RTL8812AU module on Aliexpress :

Specs are pretty detailed, but if I understand correctly, there is no integrated Power Amplifier.
Still, would the module be suitable for short range flying ?
Also could someone tell me how those Db translate versus a 25mW analog VTX (The max legal power on 5.8GHz here in France) ?

They’re nice cards, one person flies out to about 2km with them.
