Abstract: A mobile portable gas water heater, belonging to the outdoor equipment technology field. It comprises a water heater and a connector assembly, where the water heater is detachably mounted on the connector assembly. The connector assembly consists of a supporting portion, an adjusting portion, and a connecting portion. The connecting portion is fixedly attached to the back of the water heater, while the adjusting portion is detachably connected to the supporting portion. The connecting portion can be installed on the adjusting portion and is detachably connected to it. The adjusting portion regulates the installation height between the connecting portion and the water heater.
