Prob not a necessary item because just about anything can be used to hold extra water but being compact, light, and large capacity but fillable under a shallow sink goes in the pros column. Trying to fill an empty 2L soda bottle or gallon jug under a small sink isn’t easy. 2L should be good to boil water for a pasta dinner, coffee in the morning, and some left to drink.
