Did they have portable radios in the 30s?
The vast majority of radios in the 1930s were very large console radios. They had heavy wooden cabinets and looked like furniture. But they did also have portable battery operated radios too. They used a 1.5V dry cell to power the tube filaments and a 45V to 150V dry battery to power the tube plates. These batteries alone might weigh 1 to 2 pounds, so although the radios were portable they were not light weight. Also as these radios used fewer tubes than the console radios did, they usually had lower sensitivity, selectivity, and "extra features" so could not pick up as many stations or receive as many bands or produce as good sound or support "magic eye" tuning, etc.

Does a 7200mAh battery last longer than 4400mAh?
mAh stands for milliamp hours and is a partial measure of the energy that can be stored in a battery. It is the standard used for rechargeable batteries but rarely used for non-rechargeable batteries. The rating is only a partial measure because the voltage affects the total energy stored. For a given mAh rating, the higher the voltage of the battery, the more energy can be stored. For two batteries that deliver the same voltage, a 7200mAh battery will store more energy than a 4400mAh one. Therefore, the 7200mAh battery should last longer. There are other factors that affect how long a battery can last. The type of load can have a significant effect on the battery life and the condition of the battery itself.
