The short answer
Cordless fountains run on a rechargeable battery, so they go anywhere and remove cords cats chew; makers state from about a month (PETUNO, PETLIBRO Dockstream 2) to six months (FEELNEEDY filter-free) per charge, depending on mode. Corded fountains run continuously without recharging.

Sensor modes
Sensor modes run water only when a cat approaches, stretching the battery, but a cat that drinks quietly may not trigger them. Timer modes are a good fallback.
Which to choose
- Cord chewers or no nearby outlet: cordless.
- Heavy drinkers or multi-cat homes: a large corded tank, or a large cordless one like CEESC 4 L.
- Lowest upkeep: corded.
