Capacitors instead of rechargeable batteries
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).

capacitors instead of rechargeable batteries | Electronics Forums
Capacitors are less energy dense than batteries (so a capacitor bank is larger for a given amount of energy) Capacitors have a voltage which decreases as you discharge them. Batteries tend to maintain a more constant voltage for longer. This means that it becomes more difficult to provide a stable voltage from them under load and over time.
