Adding a diode will create a 0.7V voltage drop (for a typical silicon diode) at the router, so instead of 4.5V the power supply is putting out, the router will only see 4.5-0.7=3.8V at the router, which would be within the range of a Lithium battery voltage range (Lithium batteries have voltages ranging 3.3 - 4.2V).
Anvender vi kun batterier til at håndtere spidser frem for at erstatte al anden energiforsyning, så har vi jo slet ikke brug for kapacitet i den størrelsesorden du nævner, Holger.
