There are two parts to the power adapter rating: The voltage and the
current. What is the current output rating of the other adapters that
don't? It could be that the routers take 1-2 Amps and the generic
adapters are capable of less than that. A USB port can only source
500mA per hub which unlikely to be able to power an entire router.
