Both electric and non electric types have their own pros and cons. The standard water bag is simple to use and they are flexible. It also remains warm for a longer period of time provided the cost is also comparatively low. But unlike the electric hot water bag, they don’t inform you about the water’s temperature. The electric hot bag gets heated within 5 minutes and has many advanced features. They also come with an auto-cut feature and hence you don't have to any disadvantages or threats either. Electric water bags are the best as they are more advanced.
